Re: Windows XP Blue Screen. Re-installed windows and it did not solve the problem.
If reinstalling Windows altogether after a format didn't do the trick, then you can bet your bottom dollar it's a hardware issue.
You'll want to use another computer to download and burn the
UBCD. It has a bunch of hardware diagnostic tools in it that should do the trick. You'll want to access the following in order:
Memory: Memtest86+
CPU: Mersenne Prime Test (latest version)
Disk: Seatools
For memtest86+, just let it run its course overnight (at least 7 passes).
For Mersenne Prime Test (Prime95), let it run minimum 12 hours.
For Seatools: Select Long and Short DST.
If Memtest finds errors, remove memory until only one stick is present. Then test again. If errors again, replace stick with another using the same slot. If that one doesn't error, assume the first one is the culprit. If both error, change memory slot. If they continue to error in new slot, you got a bad motherboard and/or power supply.
If Memtest shows no errors, run Prime Test. If after 12 hours it displays no errors at all, move to Seatools. If it does, assume CPU as problem.
