PC freezing and I've ran out of ideas to try

I have an increasingly frustrating problem with my PC in that it regularly freezes. I've tried all of the suggestions that I've been able to find for similar problems in this forum – further ideas would be greatly appreciated!

Symptoms:
The PC freezes regularly, but with no obvious pattern of application, time lapsed etc. It can freeze during normal gameplay, browsing or office applications; it can freeze when the PC is idle (there are no screensavers or power-save options) and it has once froze during start-up before Windows XP has loaded.
There are other occasions where the PC can run for 4+ hours without a crash.

I’ve tried:
? Removing and re-seating the RAM.
? Swapping over the RAM cards
? Running Memtest86+ (no reported problems)
? Ran downloaded temperature monitoring software, with no indications of overheating
? Making sure that the hard-drive has more than 20% free space
? I have up-to-date Sophos anti-virus running
? I run Ad-aware and Spybot regularly
? I have all of the Windows XP patches and updates.

I’ve got as far as I can – can anybody suggest anything else to try ?

Try a system file scan, go to Start/Run/type sfc /scannow (Watch the space between sfc and /) hit enter. You will need your XP CD

It is about 2-3 years old and it is an ASYNC 300 watt. Could this be a potential problem ?

have you added any recent hardware?

try this click here I don't know if it's the cause but worth a look just to rule it out

No new hardware has been added in recent months

I would add A.V.G.Anti-Spyware or A Squared on to that also SpywareBlaster.

Black66,

have you checked out Control panel-administrative tools-event viewer-system.

This should give a clue, as to the cause of the problem/s.

I had the same and it was the psu. a small blip in the voltage caused freeze with no windows error messages.

Joe R - There are no event messages around the times of the crashes and other messages in the log look non-critical
