Quick and problem-solving

calculator breakdown that appears confusing, intangible. And the components of the Windows operating system is relatively intricate, microprocessor event of a failure, for the mean user, you want to needlepoint the reasons for its failure is nearly impossible. So it is that if we encounter when the microcomputer failure, entirely helpless out? This is not so, the computer-generated however there are numerous reasons for failure, but if we see carefully, conscientiously amount up, we can still have some computer failures of the law and treatment reaches. In this brochure, we will some of the most common and most typical computer fault diagnosis, maintenance usages to show you, through it, you'll find - ways to solve computer failure on your side, easy, but efficient!


one motherboard motherboard

key component of the plenary computer, the computer plays a vital role. If the motherboard malfunction will affect the work of the whole PC computer system. Here, we take a look at the motherboard in the course of which the most common faults.

a common fault: boot no display no display

computer boots, the first entity to check is a BIOS. Motherboard BIOS, the hardware store important data, while the motherboard BIOS is part of the more vulnerable, easily damaged, once damaged it will cause the system can not run, the recurrence of such failures are generally due to the motherboard BIOS damage caused by CIH virus (of course not rule out the motherboard itself, cause a system failure can not run..) General BIOS hard drive after the virus devastated the data will be lost, so we can detect the hard disk the data is intact to decide whether the BIOS is damaged, if the hard disk data intact, so there are three reasons why the phenomenon of power no display:

1. because the motherboard or expansion card expansion slot problems, leading to plug in expansion card, such as sound cards, etc. without the display board is not responding.

2. motherboard jumper settings in the CMOS in the CPU frequency does not, it may lead to not show fault, which, by the time the clear CMOS to be addressed. Clear CMOS jumper on the motherboard commonly near the lithium battery, the default place is generally 1,2 short, just short of his conversion to jump a few seconds for the 2,3 to solve the problem, the antique motherboard for the elapse can not be found should the user to the jumper, just remove the power cell, enter the CMOS settings to be displayed after the boot off, will go up also reached the CMOS battery expel purposes.

3. motherboard does not recognize the memories,GHD Blue Straighteners, memories corruption or memories does not mate the boot no exhibit can lead to failure. More selective in some older motherboards memory, once the plug in the motherboard does not recognize the memory, the motherboard will not begin, and even some motherboards do not give you any fault tips (tweet). Of way sometimes in mandate to amplify the memory to enhance system rendition, the results of alter plug brands, types of memory can also cause such a failure occurs, so upkeep should pay more attention.


for the failure of the motherboard BIOS is damaged, we can plug in the ISA card to see whether the display (If prompted, can prompt steps below.), if I were you the boot screen, you can own Automatic Updates BIOS to do a floppy disk, reload the BIOS, but some motherboard BIOS is damaged, the floppy drive did not work this time, try using hot method to solve (I have tried, at a time the BIOS the same at the same class of motherboards can be successful author..) However, in addition need to use the same BIOS hot things, some components may cause damage to the motherboard, so a reliable method is to write code using the BIOS update file to write device inside the BIOS (this service can find a safer computer vendhardly everlution).

Troubleshooting II: CMOS settings can not be saved
such failures are generally due to insufficient battery voltage caused by the motherboard, which can be replaced, but some board battery replacement also can not solve the problem, at this time There are two possibilities:

1. motherboard circuit problems, which are looking for professional service;

2. motherboard CMOS jumper problem, sometimes because of the error will jump on the motherboard CMOS line is set to clear the alternative, or set to an external battery, making the CMOS data can not be saved.

Fault Three: In Windows, install the motherboard driver CD-ROM drive read the disk after a crash or slow down the phenomenon

in some no-name motherboard sometimes such a phenomenon, motherboard drivers programs Bahrain, can not restart the computer into the Windows 98 desktop, normal mode, and the driver under Windows 98 can not be uninstalled. If this occurs, it is recommended to re-find the latest drivers installed, the problem can be solved generally, if it is not, can only re-install the system.

Troubleshooting four: Install the Windows or start Windows when the mouse is not available

recurrence of such failures in the software causes the error is generally caused by the CMOS settings. Power treatment settings in the CMOS has a modem use IRQ field projects, and his options are 3,4,5 ......, NA, generally it is the default option is 3, set it to 3 other than items can be disturbed.

five common faults: prevalent computer crashes, during the CMOS settings will appear the phenomenon of necrosis

Dead phenomenon happened in CMOS, usually the motherboard or CPU have problems, should the press law can not troubleshooting, it can only replace the motherboard or CPU.

such failures usually occur because of a problem with the motherboard or the motherboard designs Cache heat caused by bad, I had found in the 815EP motherboard is not good enough for the motherboard heat caused by the failure phenomenon. Touch the CPU after the crash around the motherboard components, found that the temperature is very hot. After replacing the high-power flare, crash failures can be resolved. Cache problem for the failure, we can enter the CMOS setup, the Cache can fix the problem after the ban, of course, Cache ban would certainly be an shock upon the speed.

Troubleshooting Six: board COM port or parallel port, IDE port failure

the recurrence of such failures are generally due to causes narrated hardware hot plug the user, the user can use this time instead of multi-function card But in lieu must be disallowed before the COM port on the motherboard comes with the parallel port (some motherboards with IDE ports to be banned for proper use.)
graphics
a common fault: boot no display

such failures are generally due to poor contact with the motherboard or graphics slot motherboard causing problems. Fhardly everme integrated graphics motherboard, main memory if the shared memory, you need to pay attention to the location of memory, usually in the first memory slot should be inserted in memory. Causes the graphics card no display power failure,GHD Straighteners, power is generally given after a long, two short beeps (AWARD BIOS for the card is cared).

Fault Two: Show Huaping, blind to the penmanship

such failures are generally due to high-resolution monitor or video card does not support caused. Huaping startup mode can be switched to safe mode, and then again in Windows 98 into the display settings, select the state in 16 colors Restart in normal mode Windows 98 system, delete the graphics drivers, restart the computer. Or not to enter safe mode, in a pure DOS environment, edit
SYSTEM.INI file, display.drv = pnpdrver to display.drv = vga.drv, the Save and exit, then drive in Windows to update the
program.

three common fault: color display is not normal, such failures are generally the following reasons:
1. graphics card and monitor signal line is bad
2. display their own fault
3. In Some software to run when the color is not normal, usually common in older machines, there is a check in the BIOS, the color of the option to open it to
4. Graphics damage;
5. display is magnetized Such phenomenon is generally due to magnetic objects can be caused by too close, magnetized may also cause the display appears deflection phenomenon.

Fault IV: Death

the recurrence of such failures are generally more common in non-compatible motherboards and graphics cards or motherboards and graphics cards bad; graphics card is not compatible with other expansion cards can also cause crashes.

five common faults: the screen pattern of irregular noise or

such failures are generally due to problems with memory or graphics cards caused by poor contact with the motherboard. Finger position to be clean or replace the graphics card was
card.

six common faults: lost

graphics driver graphics driver to load and run automatically after a period of loss of driver, such failures are generally of poor quality due to video card or graphics card and motherboard do not compatible, making the graphics card temperature is too high, causing the system to run unstable or freezes, then only replace the graphics card.

addition, there is a class of special circumstances, the previous graphics driver to load, but the graphics drivers loaded into Windows when the break occurred. To change to other types of cards in loading its driver, insert the old card to be addressed. Should such a failure can not be determined, then the registry failure to restore the registry or reinstall the operating system can be. A common fault

sound: sound dumb. There are common causes of this failure:

1. Default output driver is Click the sound icon bottom right edge of the screen (small loudspeaker), appear to accommodate the volume slider below the

2. soundcard conflict with other cards. PnP card solution is used to adjust system resources so that all cards without agitating each other. Sometimes, open the

3. After installing the Direct X sound card is not aloud. That this sound card with Direct X compatibility is not good, need to update the driver.

4. one channel silent. Check the sound card to the audio speaker cord is disconnected.

two common faults: excessive noise from the sound card. There are common causes of this failure:

1. Card is not correct. Manufacturing precision is not lofty enough for the chassis, sound card manufacturer or installed appearance the damper caused along wrong sound card tin not be closely integrated with the motherboard expansion slots, can be seen visually on the card This phenomenon in the ISA card or PCI card has, are general problems. Pliers generally obtainable alteration.

2. Active Speaker Speaker input connected to the sound card output. For the lively speaker, should be joined to sound card Line out side, it has not been
output signal amplifier on the card, the noise is much smaller. There is only one output card is the Speaker or Line out jumpers on the card depends on the decision, the factory default is often Speaker, so the jumper to disconnect the sound card.

3. Windows comes with a bad driver. Sound card driver is installed, you should select the catalogue box. If you have installed the Windows driver that comes with the optional Installation. Then insert the disk or CD-ROM with sound card, load the driver provided by the manufacturer.

Fault Three: Sound can not I once had a sound card under Windows 98 using the original driver disk to install the driver install does not material how, and had to replace the use of Creative SB16 driver, everything is normal. Then upgrade to Windows Me, not normal and back with Windows 2000 (full version) comes with just the normal sound card drivers.

2.'s most provoking problems than the Windows 9X Plug and Play device under test has chosen to given a free hand to help you install the driver, the driver side is not used, then, every time you delete out reloading will repeat this, and can not use the Here I reveal a secret detached trick: Go to Win9xinfother directory, the *. inf file on the sound card, delete all and restart manually after installation, this was one hundred percent efficacious, have saved innumerable lives ... ... of course, sound card, change up table can accomplish the same purpose.

3. does not support the PnP sound card installed (also applies to not use the PnP install the PnP sound card): Go to Windows quest for new hardware?

Troubleshooting four: Play CD silent


1. completely silent. With Windows 98's Using a 4-pin CD-ROM audio cable to connect the analog audio output and CD-in on the card can be, this line will buy CD-ROM included.

2. there is only one channel sound. Optical output marking generally almost two lines, the middle two lines to floor. Because the audio signal line 4 line color is generally different, the color can be found from the line correspond to the interface. If only one interface just aboutund card and audio cable for every interface does not match the wiring had to change the order of the audio line, usually only one of two lines of the change can be.

five common faults: PCI sound card

sonic rumble occurs generally because PCI video card technology caused by Bus Master PCI bus hung on the hard disk read and write, mouse movements and other operations to amplify the background
noise's sake. Solution: Turn off the Bus Master PCI card functions into AGP graphics card, sound card for the PCI slot.

six common faults: not the normal recording

first check if there is nought wrong with the loudspeaker jack into the other, and second, double-click the little speaker, elect list see if the settings are correct. Then in the If the

seven common faults: Can not Play Wav's, Midi Wav Music

can not play music phenomenon is rare, often due to One can disable; can not play MIDI files may have the following 3 possible:

1. Early ISA sound card 16-bit mode may be due to 32-bit mode is not compatible with the MIDI playback is not caused by the normal, by installing Software wave table
way should resolve

2. Today, most of the renowned PCI sound card with wavetable synthesis technology, if the MIDI playback is not part of it is likely because you do not load the appropriate sound wave table library.

3. Windows volume control in the MIDI channel is set to silent mode.

eight common faults: PCI sound card to use in the WIN98

Some users do not normally reflected in the sound card driver installation process everything is normal, no apparatus conflicts occur, but the following is not in WIN98 loudly, or cause other problems. This phenomenon usually occurs in the PCI sound card, amuse check the installation process your PCI sound card inserted in the treatise which PCI slot. Thermal attentions for some friends, like to stay away from the sound card plugged into the AGP slot, near the ISA slot that several PCI slots. The problem often arises here, because there is a Windows98 Bug: sometimes only correctly identified and inserted in the PCI-1 PCI-2 sound card two slots. ATX motherboard in the two afterward to AGP is the PCI-1 PCI and PCI-2 (the opposite in some ATX motherboard, close to the ISA is the PCI-1), so if you do not have the PCI sound card installed in the correct slot, the problem would be created.
memory


computer memory is one of the most important parts, and its role in mistrust, then the memory what are the most common faults it?

a common fault: no display

boot memory because the recurrence of such failures are generally due to memory with the motherboard memory slot is bad cause, by the time smear his finger back and ahead with the eraser position to solve the problem (Do not use alcohol and other cleaning), there is memory corruption or a problem with the motherboard memory slot can also cause such a failure.
memory causes the boot no display failure, the host speaker beep usually for a long time (for the Award Bios is concerned).

Troubleshooting II: Windows Registry damage often for no reason, prompted for a user to revive

such as memory failures are generally caused by poor quality, it is difficult to repair, replace only one way .

three common faults: Windows often automatically enter secure mode

such failures are generally due to the motherboard is not compatible with the memory or memory caused by poor quality, common in high-frequency memory for Some do not support this frequency of memory on the motherboard, you can try to reduce the memory within the CMOS settings to see whether the read speed to solve the problem, should not, it can merely replace the memory.

Fault IV: random crashes

such failures are generally due to the option of several different memory chips, due to the memory of different speeds to produce a time distinction resulting in death
machine, which can reduce the memory speed CMOS settings to be resolved within, otherwise, the only way to use the same type of memory. Another possibility is that memory is not compatible with the motherboard, these phenomena generally rare, the other is also possible that poor contact with the motherboard memory computer irregular crashes caused. 01

five common faults: memory to increase system resources, but decreased after the

such phenomena are generally not compatible with the motherboard and memory caused the high frequency of memory usually found in memory fknow next to nothing ofme does not support this frequency of memory on the motherboard, such a failure when you try to COMS memory speed will be set too low point try.

six common faults: some software often runs out of memory prompts

This phenomenon is usually due to inadequate system disk space left, you can erase some useless files, leaving some space that is can be generally retained at
300M or so.

Fault Seven: Install Windows to boot from the hard drive to detect disk space, memory

hinted such failures are generally due to the user in the config.sys file, increase the emm386.exe file, by the time it disguised problems can be solved. CD-ROM pedal is

computer hardware components in one of the shortest life. In truth, many scrap the drive there is still much of value, just click on it a little maintenance. This often do not have any mysterious wisdom of radio, do not need everything too complex to use the repair tools and materials. Just look carefully and with reference to the implementation of the following symptoms of some troubleshooting, I believe you can restore the old drive or the old

common fault I: drive is always working hard disk light flashes

This is an fantasy, it is not. Because of the hard disk light flashes and the hard disk drive with an IDE interface connected, the disc also control the hard work the results of light. Drive element can be connected to a unattached IDE interface.

Fault Two: In the Windows environment to operate on the CD-ROM to display ROM to a certain extent. Most CD-ROM connected to IDE hard drive interface does not assist
Windows 32-bit disk way, the Windows generated an internal error crash. After entering Windows, the check box is closed, the confirm, then restart Windows, in Windows, and then way the CD-ROM will not go into error.

Fault Three: drive can not properly read the disk, displayed on the screen: ?

In this case, the virus should be detected by antivirus software on the machine to check anti-virus, the virus can not find the file if the redactor to open C under the basis directory of the CONFIG.SYS if they put up light drivers and drivers are broken, and processing, but also with a text amending software View No issues were found more than two steps, removable drive maintenance.

Troubleshooting four: drive to use when prompted to read and write errors or diskless

this phenomenon mostly in the changer Shihai No area to operate on the drive caused by the fault. for all the operations drive will need to wait for the CD like the bit when the arrow shows the operation can be conducted. In Play DVD when the time should also be transferred to zero and then changer, which can avoid the above error.

five common faults: when playing VCD movies pause or broken screen phenomenon

check the AUTOEXEC.BAT file on MSCDEX.EXE after. If so, you should put
SMARTDRV statement prior to the MSCDEX.EXE; Party not to use high-speed CD-ROM rushed process to SMARTDRV.EXE / U; failure can be ruled out.

Troubleshooting Six: CD-ROM in the read data, read and sometimes not, and the longer the time to read the disk drive

not read the disk hardware failure focused on the laser head assembly, and can be divided into two kinds: one is caused by using long laser tube of the old
; the other is the photocell lens surface is dirty or dirty and transmission of the laser tube deformation. So the power to adjust the laser tube, the need of optical lens tube and the laser tube cleaning.

photoelectric tubes and focusing lens cleaning method is: Disconnect the laser head assembly, a flat cable, remember the intention of the laser head teams separately pieces. then see hooded jacket laser focusing lens, remove the jacket will find that focusing lens from the four fine copper wire connected to the focus, tracing the reel, the optical tube assembly is installed in the bottom of the lens holes in the. with a fine wire mantled in clean cotton mallet a small value of distilled water (not optical tube with an alcohol wipe and focusing lens surface), and to see whether the level of the lens on the laser tube is suspended, it shall be adjusted appropriately. Thus, the cleaning is completed.

adjust the laser power. in the side of the laser head convergence screws are a little like a across potentiometer. the use of color and write the initial position, generally the first clockwise 5 ° ~ 10 °, installed No re-test machine turn 5 ° ~ 10 °, until a smooth read the disk. Note must not rotate too many, so much power and burned photocell.

7 common faults: boot drive not found or observation failure

This may be due to drive data cable connector is loose, damaged or the hard disk drive data cable jumper settings error caused by such problems encountered when
waiting, we should first check the CD-ROM The data cable connector is loose, and if found not plugged in, it will be re-plugged, plug tight. If this does not resolve the fault, we recruited a new data can be put on line to try. this time if the fault still exist, we need to check the jumper settings CD-ROM, and if there is an error, change it to.
mouse mouse
failure analysis and maintenance is relatively simple, most of the fault for the interface or key contacts bad, broken, dirty mechanical positioning system. a few failures for the internal components or circuit Weld mouse, which are found in certain low-quality products, especially in the light-emitting diode, IC circuit damage to the bulk.

A common fault: can not ascertain the mouse

1. mouse completely damaged and need replacement mouse.
2. chained to the host serial port or mouse PS / 2 spoken exposure bad, cautiously take a good line, re- can start.
3. motherboard serial alternatively PS / 2 ports from getting harmed, this position is rare, if this is the circumstance, had apt replace a motherboard alternatively use a serial port on a multifunction card.
4 . mouse line is bad, this is the most common. bad points more in the mouse inside the wire and perimeter board connections. fault by the time not another PS / 2 joints, the general is not complicated to mend. usually due to relatively short lines, or compare the mouse lines are messy and hard plucking causes the reason, the solution is to open the mouse, and then use a soldering steel to solder solder. there is a situation that is bad inside the mouse cable is long because of the time result caused by aging, such failure is often tough to find, replace the mouse is the fastest solution.

two common faults: the mouse can be shown, but can not move

the flexibility of the mouse down, not as arbitrary pointer, but slow, incorrect positioning, or simply could not move. This is mainly due to mechanical positioning the mouse scrolling axis in the collection of transportation failure caused by undue filth, rolling does not cause amenable. maintenance of the internal focus on the mouse X axis and Y axis on the displacement machinery. The solution is to glue the pellet to open the latch chips, remove the mouse pellet to coil, with a clean napkin dipped in mild cleaner on plastic cleaning the pellet, the friction shaft can be cleaned with alcohol. The best place in the axis of drop a few dew of sewing machine oil, but it must be thoughtful not to stream to the friction surface and the suture on the grid encoder. will all the clay removed, the flexibility of the mouse ever resume.

three common faults: the mouse button failure

1. the mouse button without movement, this may be because the mouse button and the circuit board micro switch is too far away or press on the switch after a phase of reduced aptitude to use the bounce. open the mouse, the mouse buttons below the moderate thickness of glue a piece of plastic film, the thickness is resolute according to actual needs, can be used after treatment.

2. the mouse button is not the normal pop-up, this may be because when the key alternate in the bottom of the bowl-shaped micro-fracture caused by exposure to film, principally the long-term use of plastic is accessible broken reed. If a three-button mouse, you can a key that will remove the navel to the emergency. If it is good quality original brand-name mouse, you can solder, the open micro switch, carefully clean the contacts, some of the grease, the bottles can be secondhand.
Keyboard
keyboard in the course of the fault manifestations are varied, the reasons are multi-faceted. There is bad failure, mechanical failure has its own keys, as well as logic circuit fault, Xu Han, false welding, sealing off and the metal hole oxidation failure. repair the fault phenomena according to the thinking of different decrees, find out the cause of the malfunction, make the appropriate repairs.

a common fault: some of the keys on the keyboard, such as space key, the Enter key does not work, sometimes, correction shall be entered many times before - one or two characters, and some
keys such as cursor up key is pressed longer, continuously moving the cursor on the screen, this time the keyboard other characters can not enter, need to press again to bounce
.

this failure as a keyboard new keyboard, the keyboard is too periodically the card key failure occurred. there keyboard card key phenomenon caused by the following 2 reasons: an cause is keycap insert the retinue rank offset column, behind urgent the clasp makes the keycap the body can not gambol a outcome of shell stuck the card key, and because this reason occurred in or approximate the new keyboard on the keyboard. Another reason is the key long-term use, the return spring bounce becomes penniless, shrapnel and reception the pry friction larger, can not make key gambol caused by card key, because this occurred in the long-term use of the keyboard. When the keyboard appears while the card key mistake can be apportioned under the keycap, and then reception the pry press. If the projectile by not up or labor, is caused by the second, otherwise the first causes. If the keycap and the key causes the body shell stuck in the put a gasket among the body, some of the pads can be slightly harder plastic (such as discarded diskette jacket) made of, its size is equal to or slightly larger than the key to body size, and press the pry in the location to open a can through the ammonium Rod freely through the square hole, in consensus with its set of poles, plug keycap; with the keycap and the key pad to stop the body stuck, you can repair problems clasp; if the spring fatigue, resistance to convert massive shrapnel card key causes failure, then the body can be special key to open, a little stress return spring to reinstate bounce; clear the shrapnel ambition be key to the restoration. by removing the shrapnel and reduce the resistance by wand bounce to get the mistake button the resumption.

Fault Two: Some characters can not enter.

if not one key character can not enter, it may be the key failure or joints Weld. inspection, in accordance with the the method depicted above, open the key
disk, measured with a multimeter resistance outline of the on-off status of contacts. If the key does not always turn on when pressed, then button reed fatigue or bad, in need of repair or replacement; if key press off when the contacts under normal, that may be due to cold solder coupler, sealing off holes or gold scrap due to oxidation can be measured onward the printing line, paragraph by paragraph, to find fault re-welding; Ruoyin metal hole oxidation and failure can be clean oxide wafer, and then re-weld; if caused by the metal hole completely off circuit, it can lead to connect appended welding.

three common faults: if only in the same column number, not in the same line can not enter the key.

line or lines may be lines elsewhere in the column circuit, or logic gate circuits may be malfunctioning. this time available for testing 100MHz high frequency oscilloscope to find the device cold solder joint failure point, and then repair.

four common faults: keyboard input is inconsistent with the temperament shade.

such failure may be due to the phenomenon of short circuit caused the board, and its performance is The key is shown as the same as the other characters, this time can be weighed multimeter or oscilloscope to determine the fault repair after.

five common faults: press a key produce a string of multiple characters, or bounce when the character key.

This phenomenon is caused by a logic circuit failure. the first characters of a column is selected, if the enter key of a row without a column, may produce the phenomenon of a number of other characters ; if the one with the Enter key, the character will have a bounce into the system and can not be the last phenomenon, with an oscilloscope checking logic circuit piece, the piece to find fault with the model after the replacement of the new chips, troubleshooting.
Modem
A common failure: 56K of the Modem is not up to 56K. This problem can be from the following considerations:

1. 56Kmodem actual highest speed can only reach 53K know next to nothing of, to consider various effects, 56Kmodem speed generally between 45-53K.
2. Modem telephone line to a large extent influence the transmission rate, if the phone line quality is not good, line voltage instability, 56K on the Modem
to fewer than 56K; Another use of the Internet extension will also affect Internet speed.
3. not installed the correct driver.
4. and the ISP uses different protocol,GHD Midnight Gift Set 2011, only your Modem and your ISP concert is the same, Modem will meet the standard 56K.
exclude the above reasons, your 56K Modem is still much faster than 53K, this is your Modem hardware problems can be considered a replacement or repair
.

common Failure II: Modem disconnects often, the problem may have dropped the following reasons:

1. Phone line quality is not good;
2. If the data terminus ready (DTR) signal is invalid duration Modem settings than the default, it will lead to dropped calls;
3. If your phone has a open;
4. In addition, Modem their quality and compatibility problems between different Modem Modem is caused by a common cause of dropped phones.

three common faults: Modem not turntable intonation

time when the Internet late at night when the dial tone in order not to inspire others slumber, through the applicable AT command to change: You can use the ATM0 set Modem no dial tone, and ATM1 set to Modem Dial-up articulation from a dial tone . For the alternative of the volume you can change the following instructions, ATL0 (cheap volume), ATL1 (cheap volume), ATL2 (in volume), ATL3 (high volume).

four common faults: Fax speeds up to non- 14400

Modem to the maximum fax rate is 14400, and send a fax rate of only 9600. This is because most of the fax machine to send and receive rates are
is 9600, and only use the rate of 14400 or 33600 fax, Modem fax speed will reach 14400.

five common faults: Modem can not dial or connect

if I were you installed correctly on your Modem, communication will not work. The following lists the authentication process of the communication Modem with Windows installed an antagonistic driver files, could lead to COM port and Modem not working properly, it should first check if the correct Windows98 loaded file.

1. Testing existing communication file
(1) the System catalogue and SERIAL.VXD COMM.DRV Windows95 floppy disk or CD-ROM file with the original file to compare, check
check the file size and appointment is the same.
(2) confirm the System.ini file in the following lines: [boot] Comm.drv = Comm.drv [386enh] device =* vcd
(3) in the Run ini is also not associated with the
* VCD file. These files are built in at the VMM32.VXD.

2.
test the modem's configuration in the , click the option, set the maximum baud rate modem support, and click .

4.
check the correctness of the port in the br> listed port is correct. If not, please select the correct port, and then click The present resource settings, see the modem's manual to find the correct settings in the conflict with other devices, click the
use the same variety of IRQ, and in most computers can not use. COM2 and COM4 have the same problem. If possible, change the COM3 and IRQ settings
COM4 port, so they no longer clash. Also , there are some graphics card and COM4 port addresses conflict, the clash if found, use the other ports,GHD Hair Straightener NZ, or replace your graphics adapter.

6.
test port settings in Double-click experience.

7.
test the modem baud rate in the wag
special rate is set to the correct rate.
Note: If you call the main system in the original set baud rate can not communicate, then reduce the baud rate sometimes may resolve the problem.
printer
in the bureau, the inkjet printer is then used in a more general one device. inkjet printers due to the use, maintenance, unfit operation and other factors will often be some failures, how to address the concerns of the user. Here we put journal work and treatment of common faults summed up, we want to assist.

a common fault: printing ink scanty, indistinct handwriting processing, most of the fault is due to the printer does not use or long-term other reasons, resulting in the ink delivery system disorders or nozzle clogging.

exclusion: If the nozzle clogging is not very mighty, then the implementation of the printer instantly to the cleaning operation. If no effect after continual washing, you can win the cartridge (one for non-printer cartridge nozzle, the nozzle need to win,GHD Deluxe Midnight 2011, but the need to carefully), put the nozzle in warm water soak for a while, attention must not be part of the circuit board is also immersed in water, or else , stained with digestive periodical to take away the water droplets, and then washed several times fitted with nozzles on it.

Fault Two: Replace the new cartridge, the printer in the boot panel on the processing

normal circumstances, when the ink has run out of time It is possible cartridge not fitted properly, the other may be won in the off state, self-old cartridge, replace with a new cartridge. as to replace the print cartridge, printer ink will charge the ink allocation system, and this process can not be turned off, so the printer can not detect the re-install the cartridges. In addition, some printer ink capacity of the dimension is the use of electronic counters inside the printer to the calculate (especially in the use of color ink, the statistical ), when the counter reaches a certain merit, to determine the printer ink exhausted. The process of replacing the cartridge, the printer will carry out its inner reset the electronic counter, thus confirming the installation of a new cartridge.

solution : Turn on the power, the print head moves to the cartridge replacement position. the ink cartridges installed, get the printer to charge the ink, the ink filling process is finished, troubleshooting.

three common faults: soft plug in the nozzle Treatment of soft plug plug

mean for manifold reasons on the viscosity of the ink in the nozzle due to break bigger fault. general use elemental ink cartridges can be restored after reiterated bathing, but this path also many garbage of ink. The easiest direction is to use your hands to the head of vacant cartridge cleaning. with one empty ammunition cleaning before it gets inside the cartridge with a pin out of the residual ink as possible,GHD IV Black Straighteners, the cleaner the better, then add the cleaning solution ( accessories available in the mart). filling cleaning liquid should be carried out in a clean context, will add a good cleaning fluid cartridge according to the natural action of the printer on the machine, and often cleaning the printer button at its cleaning. use of the residual ink cleaning fluid merged with the ink color to publish a test light, put on a agreeable cartridge to customary after using a.

Troubleshooting four: Clean the pump nozzle in the printer troubleshooting printer cleaning pump nozzle

go wrong are more, and it is one of the chief elements causing plug. printer cleaning pump nozzle print head conservation on the certain character. Sprinklers automobile back to the bit, to clean the pump nozzle from the nozzle to the feeble pumping of manipulation on the nozzle seal protection. install a new cartridge in the printer or the nozzles are disconnected, the machine's suction pump to the bottom nozzle for exhaust through it, the higher the precision of this work mouths as possible. but in actual use, its performance and atmosphere tightness due to time, the dust and ink remnants in the mouth of the coagulum boosts. If the user is not on its regular inspection or cleaning, it will reserve your print head out of some difficulty.

this part of the maintenance method: Remove the printer's top cover away car, using a needle wash them inhaling pure water, of special note, embedded within the pores of the mouth to fully clean the gasket. In this wish to caution users , cleaning the parts, do not use ethanol or methanol to clean them, this will cause this component liquefied in the mosaic of the porous gasket distortion. The other thing to advert is that inkjet printers should be kept away from the heat and dust work environment, only a good working environment to ensure the normal use of the machine a long time.

five common faults: normal and printing ink line detection accuracy was significantly worse treatment

inkjet printers will be in use the number of times and the use of time and print accuracy become worse. inkjet print head is also a life. the general head of a new life from the beginning to the end use, if you could not see any fault more smoothly, that is, 20-40 a dosage cartridge life. If your printer has been in use for a long time, and now the printing precision variation, you can use the method of replacement cartridges to try, if for a few cartridges, print output results are the same, then you this printer's head will be replaced. If there is a change after the replacement ink cartridges, ink cartridges that you may have used poor quality non-original ink.

If the printer is new, the printed results can not satisfy you , often the print line is not clear, text graphics skew, txt, graphics outside the boundaries blurred, print out the ink control synchronization accuracy, which method you may buy a counterfeit ink cartridges or use non-original products, should be its immediate replacement.

Troubleshooting six: walking car treatment

dislocation encounter inkjet printer is a walking track car alloy of bronze powder by the two sets of circular iron shaft with a precision combination of sliding completed . While walking there is a small car devised and installed to complement the shaft lubricating fuel Felt, but the environment we live in the dust everywhere, a long time, due to air oxidation, dust the surface of the dispose of the axis of fuel aging The failure, then if it continues to use the printer, will be due to bronze sleeve axis and the increased friction caused by car voyage dislocation, can not be used until the collision caused the front.

solution is: Once this failure Turn the printer off quickly, will not return to place his hands back into the car parking spaces. to find a small piece of absorb or felt, full of oil dipped on the sewing machine oil, tweezers grip rub back and forth on the spindle. The best is to spindle removed, washed and oiled, so that the best effect.

meet another car because of damage caused by the device. the printer on top of car parking spaces have a photoelectric sensor, which is the main board to the printer print reset signal to provide an important component car. This component is too large or damaged due to dust if the printer can not find the car back to the signal due to kick the front, which led to not use the general out of the failure to replace the device.
Display
Display in a long time, a kind of small problems will follow. specialists believe that these small problems to solve is actually very simple, with a couple of eyes can see where the failures.

A common failure: the computer screen of just-machine shake so badly, and sometimes even the icons and text are not clear, but after twelve minutes and then will return to normal.

this phenomenon more in watery weather, damp inside the monitor's sake. To solve this problem, use damp sand in the food packaging to string attach with cotton thread, and then open the back cover of the monitor will hang in the damp sand the end of CRT tube nape near Block near the pipe. Thus, even in wet weather, it will not seem upon the one. to wait several minutes to appear on the screen.
seat tube leakage is due to be replaced sockets. open the back cover to see the end of the tube a small circuit board, sockets to solder on the circuit board
. carefully unplug this circuit board, and then welded pipe under the seat, to the electronics store to buy back a seat the same tube, tube socket weld and then back to the circuit board. then do not rush the circuit board back together, to go first to a small piece of sandpaper, very carefully after the end of the tube protruding pin wipe clean with sandpaper. In particular, pay attention to pin on the oxide layer, if it were not for clean and very lustered soon it will relapse. the board back together and you're done.

Fault Three: there is all lingering on the monitor screen clutter interference or lines, and the speaker also has needless ruckus.

This phenomenon is mostly caused by poor power supply interference. If too slothful to get contained, you can replace a new power supply. If there are enough hands to
power, you can also try to replace the power within their own filtering capacitor, which often can be effective; if the result is not apparent, you can switch to be replaced
.

four common faults: display Huaping.

this problem more is the video card cause. If it is new for the graphics card, the card may be of poor quality or incompatible, then there is not yet installed the correct driver. If the old card and added memory, then there may be Added into the memory and the original model parameters alter due to memory.

five common faults: display a blank screen.

card if it is damaged or broken monitors and other causes no signal sent to the monitor, the monitor light flashing constantly prompted no signal is received. If the resolution is set too high, more than the maximum resolution the display will appear black, caustic destruction of the monitor, but now the display has protection feature, when the resolution exceeds the set value is automatically protected. In addition, conflicts can also cause dark hardware.


display jitter causes



display refresh rate is set too low

set when the monitor activate rate below 75Hz, the screen often appears jitter, flicker, the refresh rate properly heaved, such as the set above 85Hz, the phenomenon of screen jitter usually does not happen again.

power transformer from the chassis too near to the monitor and work

power transformer electromagnetic interference will cause a larger, causing screen jitter. away from the power transformer chassis and the monitor where the problem can be solved.

bad power supply or power supply has been aging

many no-name computer components used in power supply work, the matters used are very poor, could easily lead to the computer poor or the power supply capacity can not keep up the circuit, when the system is engaged, the display screen will appear of special note the phenomenon of jitter. the computer when the power supply begin to age, are likely to cause the same problem.

put enough away from the speaker monitor speakers too close to the fascinating field effect

interfere with the normal operation of the monitjust about that the display screen generated string of color, such as jitter and magnetic interference.

virus trouble

some computer viruses disunite the screen display, such as: the character upside down, shake the screen, graphics, flip display. jitter screen everywhere online script, is enough to make you migrate in after the first big as an ox.

bad video card

reseat video card, the fault can be got excluded.

WIN95/98 system caused

after the write cache as is for this reason that in the Control Panel - System - Performance - File System - Troubleshooting maim all drives in write-caching, granting the problem to be solved.

power supply filter capacitor damage

open the case, if you see the power afford filter capacitor ( embark namely heads the largest capacitance) at the top of summon, then it shows bad capacitor, the screen jitter caused by power failure. for the capacitor, the problem can be solved.

common fault recorder A: Install the burner does not start after the computer

First off the computer power supply, check the IDE cable to open the case cover is fully inserted, and to ensure that PIN-1 position of the pins connected correctly. If the recorder with other IDE device uses the same IDE cable, ensure that two devices can not be set to >
Troubleshooting II: successful use of analog logging, the substantial logging but failed

recorder catered by the
alike, that is, and recorder laser power and disc read-write head matches and so on. In view of this, that using the following two methods to re-try it:
1. reduce the write speed recorder, we recommend the following 2X;
2. to replace another brand of blank disc to burn operation. there's another phenomenon One reason is that the phenomenon of laser power attenuation caused by read-write head, and if you use the same brand of disc burning, the first time were normal, it is likely related to power wastage and the head can be sent to the relevant vendor maintenance.

Fault Three: Can not copy the game CD

some large advertisement software or game software, in the production process, the protection of the CD disc to do so during the course of the disc replication will there can not be copied, resulting in the burning process the error occurred, or not work after copying to happen.

Fault IV: Burning the CD music can not melodrama properly

not always audio devices proficient to read normal CD-R discs, maximum of the normal CD drive can not read the contents of CD-RW record, so it is best not to use the CD burner to burn music. In increase, you also need to note that burn CD melody, CD-DA must be loyal with file format.

five common faults: the process of burning software to burn the disc, sometimes message means for the buffer underrun. usually in the burning process, the data needs to be burned off by the IDE hard disk interface by
sent to the host, and then transmitted through the IDE interface to the recorder in the cache (BufferMemory), the final recording machine to store the data in the
BufferMemory for recording message onto CD-R or CD-RW discs, these operations must be perennial, must not be interrupted, if any one part of a problem, will not cause the recorder normal write data, and a buffer underrun error prompt, and then to disc scrapped. The solution is, before the burning need to close some memory-resident programs, such as turn off CD auto insert notification, disable antivirus software, Window mission management and task scheduler and the screen saver and so on.

six common faults: CD burning process, they would often scald burn failed

improve the success rate of the need to maintain a simple system environment, ie Close background resident agenda, it is best to prepare for the recording system, a dedicated hard drive, specifically associated to software installation and burning. In the burning process, it is best to first file stored in the hard disk, made into and then engraved into the CD-ROM. To assure the smooth migrate of process file recorder, you need to sort out debris often hard to avert not work because the file transmit, the peccadillo interruption caused by the burning, you can perform Members send messages to the machine, will influence the burn achieve, In addition, the LAN, do not use resource sharing, if the burning process, the other users to read the regional hard disk, can cause interruptions or failure of the recording. In addition, even
