Lets make a list of Common problems and the most likely reasons, and how to
WHENEVER INSTALLING NEW HARDWARE MAKE SURE POWER CABLE TO POWERSUPPLY IS
DISCONNECTED, EVEN WHEN ATX POWERSUPPLY IS OFF THE 5V STANDBY RAIL IS STILL
CAN'T INSTALL WINDOWS
Problem: various errors during windows installation
1. Check for faulty ram.
2. Check for damaged installtion media.
3. Check for faulty power supply.
4. Check for faulty optical drive.
HARD DRIVE NOT DETECTED
Problem: hard drive cannot be detected
1. PCI bus out of specification, can cause problems
2. Power cable faulty or not plugged in
3. IDC cable in incorrectly or faulty CHECK BOTH ENDS
4. Master/Secondary conflict, disconnect all other devices on chain.
5. Check jumper settings. Some drives have a "single drive" setting, and
won't work properly as a "slave" or "master" if they are the only drive in the
6. As a last resort, ie.won't work at all after everything has been tried and
warranty is no longer valid (not if it's a new HDD), try the freezer method
(freeze the hdd in freezer then try again)
NEW CPU NOT WORKING
Problem: Cpu does not work.
1. Cpu incompatible with board
2. Chipped core(only for coppermine/athlon/durons)
3. Socket arm not down
4. BIOS may need reset
5. Fan failier protection may cause motherboard to shut down if there's no
power draw on the cpu fan socket, make sure fan is plugged in if this applies to
NEW MOTHERBOARD WONT POWER UP
Problem: mobo wont post.
1. Check if grounded properly and there's no shorts
2. Remove all unrequired hardware(soundcard, ide cables etc)
3. Make sure ATX cable is plugged in
4. Make sure your ram and CPU is compatible with this board
5. Dont forget to plug in the atx power button
6. Check bios reset pins
7. Check keyboard wakeup jumper(serious)
8. Check for correct CPU jumper settings. (If Applicable)
CONSTANT CRASHES IN WINDOWS
Problem: BSODS etc
1. Check VIA 4in1 drivers(if applic.)
2. Set cpu back to stock
3. Set ram back to stock
4. Apply SB live+via patch(if applic.)
5. Remove all hardware one at a time until problem disapears.
CONSTANT RESETS WHILE UNDER LOAD
Problem: resets under load
1. Check powersupply handling capability, test rails with a multimetre NOT
ONBOARD VOLTAGE MONITORING
2. Not enough voltage for overclock
3. Overclocked too far
4. videocard,cpu overheating
5. faulty wiring or possible shorting
6. Check All capacitors around the mosFETs supplying power to the cpu,
especially if you have an abit/epox board
Problem: burning errors
1. Check power(SERIOUS) possible faulty molex plug
2. Enable burn proof
3. remove burner drivers from control panel
4. update your burner software(nero imho causes least problems)
5. Has it happened since installing windows XP? check compatibility.
6. Update firmware
7. make sure DMA is ENABLED IN CONTROL PANEL
8. Put device on seperate chain
9. Make sure PCI bus is relatively in spec(no more than 37mhz)
10. Buy a CD-ROM Lens cleaner, the laser maybe dirty
CPU @ XX DEGREES. TOO HOT?
1. Check the fan is functioning
2. Have you applied thermal paste?
3. Apply thermal paste only VERY thinly (almost translucent)
4. Heatsink seated properly?
4a. Socket arm down all the way?
4b. Heatsink collar correct way?
4c. Heatsink not tilted?
5. CPU voltage and speed correct
6. System cooling?
If you system is not unstable, there really is no problem unless you wish to
Remember - too hot is a variable thing: What's hot for an Intel CPU may be
normal operating temp for an AMD.
LAN NOT COMMUNICATING
1. Both computers on same subnet (eg. 192.168.0.X)
2. Using straight-through cables on switch/hub?
3. using cross-over cables for direct?
4. Cable broken?
5. Network hardware functioning (hub, switch, NIC)
6. Ping each other?
6a. Ping but don't see - do you have access permissions
7. you are using a non-internet IP address (192.168.0.x, 10.x.x.x)
8. Plug and play operating systems set to yes in the bios can cause lan
SKIPPING MUSIC WHILE PLAYING GAMES/OTHER ACTIVITIES
Problem: mp3s are skipping while im playing games
1. Switch to Waveout in winamp
2. Increase buffer length
3. Increase priority of mp3 playback
4. Increase block size
1. if using XP or 2K, check to see if the automatically reboot on error
function is turned off. (right click on my computer-->properties-->advanced--
>start up and recovery[settings]-->system failure-->untick automatically restart)
also appropriate for XP and 2K restarting instead of shutting down.
2. check for faulty ram (You can use GoldMemory to test it)
3. check for faulty power supply.
4. Scan for viruses.
5. if your keyboard has them, physically remove the "Power", "Sleep" and
"Wake" Up buttons as you might be bumping the,
ERROR MESSAGE: "There was a problem installing this hardware :Hardware Name.
An error occurred during the installation of this device.
The data is invalid."
Problem: Blue Screen When Trying To Install Hardware And/Or Drivers:
To fix this problem, go to Start, Run... and type "regedit" without the
quotes, to run the Registry Editor. Navigate your way down to:
and you will see a number of keys in the form of "VEN_xxxx", where xxxx are
strings like "1102&DEV_0004&SUBSYS_00011103&REV_04". Under each of these folders
will be another folder with a long numerical name. Open each folder and look for
the "DeviceDesc" which matches the hardware you are trying to install.
Use your wireless car mouse right Click on the "VEN_xxxx" for that device and
select 'Permissions' and then tick "Allow" for "Full Control". Close Regedit and
then continue with the installation of your device. You should not need to reboot
after you close regedit but some people have found that they do.
RECOVERING FROM A BAD BIOS FLASH
Problem: System will not boot following a bios flash:
Firstly, only flash your bios when it abosolutely necessary. If you are not
sure what you are doing, then take your computer to some one who does.
With AMI BIOS you can use the "Quick Flash" Method that is described in a
file in AMIFLASH.ZIP. If you use this method, hold the magic keys DOWN with one
hand and switch the PC ON with the other hand - just don't release the keys).
Continue holding the keys DOWN until the FDD starts reading the floppy (you can
give up after 5 minutes if nothing happens). This method won't work if the boot
block is erased.
Modern motherboards have a boot-block BIOS. This is small area of the BIOS
that doesn't get overwritten when you flash a BIOS. The boot-block BIOS only has
support for the floppy drive. If you have a PCI video card you won't see anything
on the screen because the boot-block BIOS only supports an ISA videocard,
although the procedure will still run.
Award: At boot-up, the boot-block BIOS will look for and execute an
AUTOEXEC.BAT file on a bootable diskette. Copy an Award flasher & the correct
BIOS *.bin file onto a floppy and execute it automaticly by putting awdflash
*.bin in the AUTOEXEC.BAT file.
AMI: The AMI boot-block BIOS will look for a AMIBOOT.ROM file on a diskette.
Copy and rename the correct BIOS file on the floppy and power up the PC. The
floppy doesn't need to be bootable. You will see the PC read the floppy, after
about 4 minutes you will hear 4 beeps, this means the transfer is done. Reboot
the PC and modify the CMOS for your configuration.
