pc spontaneously restarts itself

Hi Everyone.
I bought a new pc from Komplett.co.uk last July. Within a few days it began to restart randomly. Over the intervening months it has been back to Komplett 3 times. They say it never goes wrong when it is with them. When I use it, it will be OK for about 4 days but then it begins to restart all by itself. I bought a surge protector but it made no difference. I have used different monitors, but no difference. I have four 1Gig memory sticks. I have tried just using two of them at a time and swopping them around but to no avail. If I turn the machine off each night the problem seems to go away, but if it's left on continuously the problem manifests after about 4 days. I have an ABIT guru clock and the temp. is not abnormal. Also some programs will crash. Notably Firefox within 1 hour of a clean re-installation of Windows XP Home. Also crashing are, Google Earth, IE7, Sygate Personal Firewall, Mozilla Thunderbird. I'm out of ideas now, except to wonder if it could be the PSU. Could our electricity supply voltage vary and cause the problems? Especially as Komplett are unable to reproduce the fault even though the pc is shipped back to them exactly as we use it here. And further, would that also cause programs to crash?

Start, Run, type

eventvwr

and click OK.

Are there errors corresponding with when it crashes or restarts?

Just had a look at event viewer. I'm not familiar with this at all, but I can see there appear to be about 3 or 4 different types of errors reported since I last formatted the HD and re-installed windows. Specifically there are errors under both the applications tab and the system tab. There are a great many instances of errors being logged. What do I do with this info?

I had the very same problem, after lots of head scratching someone suggested it was the PSU, and they were right! click here
