Quick and problem-solving power
Cause of head malfunction confusing, puzzling. And the components of the Windows operating system is relatively complicated, computer event of a failure, for the average user, you want to find out the failure to accurately
Because it is nearly impossible. So it is that if we meet when the computer failure, completely helpless out? This is not so, the computer-generated however there are many reasons for failure, but at a time we carefully
Observation, conscientiously sum up, we can still have some computer failures of the law and approximate. In this leaflet, we will some of the most common and most typical computer fault diagnosis, maintenance methods show
To you, through it, you'll find - ways to solve computer failure on your side, simple, but effective!
one motherboard
motherboard is the computer off
Key components, plays a vital role in the computer. If the motherboard malfunction will affect the work of the all PC computer system. Here, we take a look at the motherboard in the course of which the most common faults.
often
See malfunction one: boot no display no display
computer boots, the first object to check is a BIOS. Motherboard BIOS, the hardware store momentous data, BIOS, is also
The more vulnerable part of the plate, lightly damaged, once damaged it will cause the system can not sprint, the repetition of such failures are generally due to the motherboard BIOS harm caused by CIH virus (of lesson not rule out the motherboard itself fault
Cause the system can not run. .) General BIOS hard drive after the virus demolished the data will be lost, so we can detect the hard disk the data is intact to resolve whether the BIOS is damaged, if the hard disk data
Intact, then there are 3 causes why the phenomenon of power no display:
1. Because the motherboard or expansion card expansion slot problems, leadership 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, at a time the clear CMOS to be addressed. Clear CMOS jumper on the motherboard of the lithium battery with the general
Recently, its default location is generally 1,2 short, just short of his transition to jump a few seconds for the 2,3 to solve the problem, before the old board for Should the user can not find the jumper, just remove the battery, to be displayed into the boot
CMOS settings and then shut down, will work up also reached the CMOS battery expel intentions.
3. motherboard does not recognize the memory, memory corruption or memory does not match the boot no display 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 start, and even some
Board does not give you any fault tips (tweet). Of course sometimes in order to expand the memory to improve system performance, the results of different plug brands, types of memory can also cause such a failure occurs, so maintenance should be
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 treads below.), if not
A startup screen, you can automatically update your BIOS to do a floppy disk, reload the BIOS, but some motherboard BIOS is damaged, the floppy drive did not work this time, try to use the hot solution method
Decision (I have tried, by the time the BIOS the same motherboard at the same level can be successful writer..) However, in addition need to use the same BIOS hot things, some components may cause damage to the motherboard, so reliable
Method is to write code using the BIOS update file to write device inside the BIOS (this service can find a safer computer vendknow next to nothing oflution).
Troubleshooting II: CMOS settings can not be saved
Such failures are generally inadequate because the motherboard power cell voltage, which can be replaced, but some board battery replacement also can not solve the problem, then there are two possibilities:
1. Motherboard circuit problems Professional maintenance of this find;
2. motherboard CMOS jumper problem, sometimes for the wrong CMOS jumper on the motherboard is set to clear the option, or set to an outer battery, making the CMOS data can not be Save.
Troubleshooting
III: In Windows, setup the motherboard driver CD-ROM drive read the disk after the crash or cut back on the phenomenon
in some no-name motherboard sometimes this kind of phenomenon, the motherboard drivers installed
Finished, restart the computer can not enter 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: Installing Windows, or start Windows when the mouse is not available
software such failure occurred because the error is generally caused by the CMOS settings. In the CMOS settings
Power management 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 items that interrupt be.
Fault Five: Computer frequently
Crashes, during the CMOS settings will appear the phenomenon of death
Dead phenomenon occurred in the CMOS, usually the motherboard or CPU have problems, should the reception statute does not resolve the failure, it only
Have replaced the motherboard or CPU.
recurrence of such failures are generally due to a problem with the motherboard or the motherboard designs Cache heat caused by bad, I had found in the 815EP motherboard because the motherboard
Heat is not good enough result in the failure phenomenon. Touch the CPU after the crash approximately the motherboard components, found that the temperature is very hot. After replacing the high-power flare, crash failures can be resolved. Cache problem for
Fault, we can enter the CMOS install, the Cache can fix the problem after the forbid, of course, Cache ban would naturally be an clash above the speed.
Troubleshooting Six: Motherboard
COM port or collateral port, IDE port failure
the recurrence of such failures are generally due to causes related hardware hot plug the user, the user can use this time instead of multi-function card, but must be replaced before
Prohibition of 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: no exhibit
such power so
Barrier is generally bad because the graphics card or motherboard with the motherboard slots caused problems. For some integrated graphics motherboard, main memory if the shared memory, you need to disburse attention to the situation of memory, usually in the first memory slot should be
Insert a memory. Causes the graphics card no display power failure, power is generally given after a long, two short beeps (AWARD BIOS for the card is concerned).
two common faults:
Show Huaping, blind to the handwriting
such failures are generally due to high-resolution monitor or video card does not support caused. Huaping startup mode can be switched to secure mode, and then another in
Windows 98 into the display settings, select the state in 16 colors Restart in normal mode Windows 98 system, cancel 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, and then to update the
in the Windows driver.
often
See Failure three: 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 in the run-time 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, generally due to such phenomena with a attractive objects too near to the result, magnetized may also cause the display appears deflection phenomenon.
4 common faults: crash
Recurrence of such failures are generally more common in motherboards and graphics cards or motherboards and graphics cards are not compatible bad; graphics card is not compatible with other extensions can also cause crashes.
five common faults: the screen eccentric noise
Or patterns
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

often
See malfunction Six: missing
graphics driver graphics driver to load and run automatically after a phase of loss of driver, such failures are generally due to poor quality or graphics card not compatible with the motherboard
Capacity, making the graphics card temperature is too high, causing the system to run erratic or freezes, then only replace the graphics card.
addition, there is a level of special circumstances, the previous graphics drivers to load, but
After the graphics driver to load into Windows when the crash 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 resolved, then note
Registration Form 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 horn), appear to adjust the volume slider below the Regular pronunciation.
2. soundcard collide with other cards. PnP card solution is used to adjust system resources so that all cards without bothering each other. Sometimes, open the Is not sound, in truth, there is clash, but the system did not check out.
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 cable is disconnected.
Troubleshooting II: Sound Card issued
Excessive noise. There are common causes of this failure:
1. Card is not correct. Manufacturing precision is not high enough because the chassis, sound card manufacturer or installed outdoor the damper caused by bad sound card can 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 common problems. Pliers generally accessible alteration.
2. Active Speaker Speaker input connected to the sound card output. For the spirited speaker, should be connected to sound card Line out side, it has not been
output semaphore amplifier on the card, the rumpus should be small enough
More. There is only one output card is the Speaker or Line out jumpers on the card depends on the determination, 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 With If you have installed the Windows driver that comes with the optional → voice, video and game controllers
often
See Failure three: sound can not I once had a sound card under Windows 98 using the native driver disk to install the driver install does not stuff how, and had to replace the use of Creative SB16 driver, anything is normal. Then upgrade to Windows Me, not normal and back with Windows 2000 (full edition) 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, each time you delete out reloading will repeat this, and can not use the Parts Hundred percentage effective, have saved countless lives ... ... the sound card of course, adjust the registry can also 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
Search for new hardware? CD silent
1. Completely silent. With Windows 98's Using a 4-pin CD-ROM audio cable to connect the analog audio output and sound cards
The CD-in can be, this line will purchase CD-ROM comprised.
2. there is only one channel sound. Optical output signal generally about two lines, the navel two lines to floor. Because the audio signal line 4 line color is generally different, can be found from the color of the line correspond to the interface. If the sound card only
Each interface with an interface or does not match the audio cable, audio cable wiring had to change the order, usually only one of two lines of the change can be.
five common faults: PCI sound card

2. Today, most of the popular 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 wavetable sound library.
3. Windows volume control in the MIDI aisle is set to silent mode.
eight common faults: PCI sound card to use in the WIN98
some of the unusual
Users complained that the sound card driver installation process everything is normal, no device conflicts occur, but the following is not noisily in WIN98 or cause other problems. This phenomenon usually occurs in the PCI sound card,
Please check the installation process your PCI sound card inserted in the article which PCI slot. Thermal considerations for some friends, like to stay away from the sound card plugged into the AGP slot, near the ISA slot that several PCI slots
In. 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. In the ATX motherboard close to the AGP
Two PCI is the PCI-1 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, Q
Question will be produced.
Memory
computer memory is one of the most important parts, and its role in doubt, then the memory is the most common faults are what it?
often
See malfunction one: boot no display
memory because the recurrence of such failures are generally due to memory with the motherboard memory slot is bad cause, at all times tarnish his finger back and forth with the eraser part of the solvable
Decision 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, host spokesmen generally
Long beep (for the Award Bios is concerned).
Troubleshooting II: Windows Registry damage often for no reason, recommending that this requires the user to restore
Classes because of memory failures are generally caused by poor quality, it is difficult to repair, replace only one way.
three common faults: Windows often automatically enter safe mode
Such failures are generally due to the motherboard is not compatible with the memories or the memory caused by poor quality, common in the high frequency of memories because some do not patronize this frequency of memories on the motherboard, you can attempt in the CMOS settings in the lower
Keep reading to see whether the speed to solve the problem, ought not, it can merely replace the memories.
Fault IV: random crashes
such failures are generally due to the adoption of several
Different memory chips, due to the memory of different speeds to generate a time difference resulting in necrosis
machine, which can reduce the memory speed CMOS settings to be resolved among, otherwise, only among the same prototype used
Survival. Another feasibility is that memory is not compatible with the motherboard, these phenomena generally rare, the other is also possible that poor adjoin with the motherboard memory computer random crashes caused. 01
five common faults:
After the memory to increase system resources, but reduced
such phenomena are generally not compatible with the motherboard and memory caused the high frequency of memory commonly base in memory fjust aboutme do not support this frequency of the motherboard memory
, When such a failure you can try the speed of memory in the COMS will be set too low a little try.
six common faults: some software often runs out of memory tips
This phenomenon generally due to inadequate system disk space left, you can delete some useless files, leaving some space can be generally maintained at
300M or so.
Troubleshooting
Seven: Install Windows to boot from the hard drive to detect disk space, memory
reminded such failures are generally due to the consumer in the config.sys file by adding
The emm386.exe file by the time you can to block out the problem. CD-ROM drive is
computer hardware components in one of the shortest life. In fact, there is still a lot of scrap drive
Great value in use, at all times a little maintenance click on it. This often do not have any mysterious learning of radio, do not need everything too perplexing to use the repair tools and materials. As long as you carefully observe the symptoms
And catching into account some of the implementation of the following exclusion method, I believe you can restore the old drive, or old
a common failure: hard disk drive light is always flashing work
This is an illusion, 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 unit can be connected to an IDE interface, independent

See breakdown Six: CD-ROM reading the file, read and occasionally not, and the longer the time to read the disk drive
not read the disk hardware failure focused on the laser brain gathering, and can be divided into two kinds of situations: a
Species caused by the use of long laser tube of the age
; the other is the photocell lens surface is nasty or nasty and transmission of the laser tube deformation. Therefore, the power to adapt the laser tube, the need for optical lens tube and the laser tube
Cleaning.
photoelectric tubes and focusing lens cleaning method is: Disconnect the laser head assembly, a smooth cable, memorize that direction, open the laser head assembly. Then see hooded jacket focused laser
Lens, remove the jacket will find that focusing lens from the four nice copper wire connected to the focus, tracing the roll, the optical tube assembly is installed in the bottom of the hole in the lens. Thin wire with a mallet wrapped in cotton, a small amount of distilled water and wipe (not with brandy
Fine polished surface of optical lens tube and focus), 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 laser head
Component side has a little favor a cross screw potentiometer. Note the use of color under its initial position, generally the first clockwise 5 ° ~ 10 °, not re-installed test machine counter-clockwise 5 ° ~ 10 °, until it can successfully read the disk.
Note must not rotate too much, so much power and burned photocell.
seven common faults: not detected CD-ROM drive or the boot test failed
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 drive's data cable connector is lax, and if found not plugged in,
Will its re-plugged, plug firm. If this still does not resolve the failure,
GHD IV Dark Straighteners, we recruited a new data can be put on line to try. This time if the fault persists, we need to check the jumper CD
Set, if there are errors, you can change it.
Mouse mouse
failure analysis and maintenance is relatively simple, most of the fault for the bad interface or buttons, broken, dirty mechanical positioning system
Pollution. A small number of 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 is damaged the bulk.
a common failure: can not find the mouse
1. Mouse entirely damaged and need replacement mouse.
2. mouse connected to the host serial port or PS / 2 spoken exposure bad, cautiously take a good line, you can restart.
3. motherboard reg code or PS / 2 ports from getting damaged, this situation is rare, if this is the case, had to replace a motherboard or a serial port on the multi-purpose card.
4. mouse line is bad, this is the most common. Poor contact points as the mouse inside the cable and circuit board connections. Failure as long as not another PS / 2 joints, the general is not tough to repair. Usually due to
Relatively short lines, or compare the mouse lines are messy and hard dragging causes the reason, the solution is to open the mouse, and then use a soldering steel to solder weld. There is another situation that is bad inside the mouse cable is due to the time
Caused by the aging caused by long, this failure is often difficult to find, replace the mouse is the fastest solution.
Troubleshooting II: the mouse can be shown, but can not migrate the mouse
Flexibility ebb, not as peremptory pointer, but slow, inexact positioning, or simply can not be moved. This is chiefly due to mechanical positioning the mouse scrolling axis in the collection of excessive filth and
Lead to transmission failure, resulting in rolling is not amenable. Maintenance of the inner focus on the mouse X axis and Y axis on the transmission mechanism. The solution is to open the plastic pellet locking plate, remove the mouse pellet to roll, with a clean fabric dipped in
Of cleaner to clean the rubber pellet, the friction shaft can be cleaned with liquor. Axis at the best drop a few drops of sewing machine oil, but it must be careful not to flow to the friction surface and sewn on the grid encoder. Will be cleared of all dirt
After the flexibility of the mouse ever resume.
Fault Three: the mouse button failure
1. the mouse button without movement, this may be because the mouse button and the circuit board mini switch is too far away or click on the switch after a period of reduced ability to use the rebound. Open the mouse, the mouse buttons below a thick paste
Moderate plastic membrane, the thickness is determined 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 switch in the bottom of the bowl-shaped micro-fracture caused by exposure to film, especially the long-term use of plastic is easily broken reed. If it is three-button mouse, you can be the middle
It removed a key 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 flasks can be used.
key keyboard
Plate in the course of the fault declarations are varied, the reasons are various. A bad failure, mechanical failure has its own keys, for well as logic circuit fault, Xu Han, artificial welding, sealing off the oxygen and metal chasm
Of other failures. Maintenance of differ omens according to the analysis to determine, find out the cause of the malfunction, make the appropriate repairs.
a common failure: some keys on the keyboard, such as the space bar, Enter key does not
Work, sometimes, many times before root having input - one or two characters, and some
keys such as cursor up key is pressed longer, continuously moving the cursor on the screen, keyboard, other characters can not be entered at this time, need Press only
Can bounce to.
this failure as a keyboard Students. Card key seemed keyboard phenomenon caused by the following two reasons: one reason is that column keycap insert the following situation offset, making the keycap is pressed and the key body shell can not gambol caused by a stuck key cards, For this reason multiple
Born in or close the new keyboard on the keyboard. Another reason is the key long-term use, the return spring bounce becomes poor, shrapnel and the press wand friction becomes larger, can not make key gambol caused by card key, this happened because
In the long-term use of the keyboard. When the keyboard appears when the card key fault can be apportioned under the keycap, and then urgent the reception pry. If the projectile is not up, or by labor, is caused by the second, otherwise, for the first reasons. If the
The keycap and the key causes the body shell stuck into the size equal to or slightly larger
The key to body size, and press the lever in the location accepted by the ammonium can open a free passageway of the square hole shot, to set in at pole, plug keycap; keycap with this gasket to prevent stuck with the key body , you can nail problems clasp; if the
Spring fatigue, shrapnel resistance change causes a colossal card key failure, then the body can be special key to open, a little tension return spring to reinstate elasticity; clear the shrapnel will be key to the restoration. By removing the shrapnel and dwindle bounce by rod resistance
Button so that the fault has been restored.
Troubleshooting II: Some roles can not enter.
if I were you one key character can not enter, it may be the key pad failure or
Weld. Inspection, in agreement with the method narrated above, open the key
plate, with a multimeter weigh the resistance silhouette of the on-off status of contacts. If the key does not always rotate on when pressed, then button reed fatigue or bad, in need of repair
Or replacement; if key is pressed off normal contacts, that may be due to chilly solder mutual, sealing off holes or gold scrap due to oxidation can be measured by the printing line, paragraph by paragraph, to find fault re-welding; Ruoyin metal hole oxidation failure, can be rusted
Layer of clean, then re-weld; if caused by the metal hole completely off circuit, it can lead to increased solder connections.
Fault Three: If there are multiple neither in the same column, not by the same line
Key can not enter.
may be somewhere in the column line or row line circuit, or logic gate circuits may be malfunctioning. At this time oscilloscope can be used to detect high-frequency 100MHz, the device to find fault
Weld point, and then repair it.
Fault IV: keyboard input is inconsistent with the character screen.
such failure may be due to short circuit phenomena of the board
, And its performance is the key to it is displayed as the same as the other characters, this time can be measured multimeter or oscilloscope to determine the failure point for repair.
Troubleshooting five: Press a button to produce a
String of multiple characters, or key when the character steps.
This phenomenon is caused by a logic circuit failure. First select a column of characters, if the enter key of a row without a column, may produce a number of other
Characters phenomena; if a column with the Enter key, the character will have a bounce into the system and can not be the last phenomenon, check the logic circuit chip with an oscilloscope to find fault with the model after the replacement of the chip of the new chips, troubleshooting.
Modem
often
See a failure: 56K of Modem not up apt the 56K. This problem tin be considered from the following aspects:
1. 56Kmodem tangible maximum speed can only reach 53K hardly ever, to consider various effects, 56Kmodem speed is generally between 45-53K.
2. Modem tel line to a large extent influence the transportation rate, if the phone line quality is not good, line voltage instability, 56K on the Modem
to fewer than 56K; other use of the Internet extension, but also
Will affect the connection speed.
3. not installed the correct driver.
4. and the ISP uses different protocol, only your Modem and your ISP agreement is the same, Modem 56K will meet the criteria.
exclude the above reasons, your 56K Modem is still many faster than 53K, this is your Modem hardware problems can be considered a replacement or repair
.
Troubleshooting II: Modem often dropped, resulting in
Dropped calls problem may have several reasons:
1. Phone line quality is not good;
2. If the data final ready (DTR) over the period of the signal void Modem default settings, it will cause dropped;
3. If your phone has a Modem their quality and compatibility problems between different Modem Modem is caused by a common cause of dropped shrieks.
three common faults: Modem no dial
No sound
time when the Internet late by night when the dial intonation in mandate not to inspire others sleep, via the proper AT mandate to change: You can use the ATM0 no dial set Modem
Sound, and ATM1 set Modem articulation from dial-up to a dial tone. Select the volume you can change the retinue directions, ATL0 (low volume), ATL1 (low volume), ATL2 (tenor
Volume), ATL3 (high volume).
Troubleshooting four: fax rate 14400
Modem approach the maximum fax rate is 14400, and fax
Only when the rate of 9600. This is because maximum of the fax machine to mail and receive rates are
is 9600, only the rate is 14400 or 33600 using the fax machine, Modem fax speed
Rate will reach 14,400.
five common faults: Modem can not dial or connect
