Hey all, first post here, but thanks in advance for any help you can offer.

I have a PC built essentially from spare parts that treated me well for a while, but is currently is giving me an issue. It will randomly reset during use, and then will not boot. After a while (let's say a couple hours) it will boot, run checkdisk, then to Windows as normal. Of course, this only lasts about 20 minutes or so before it restarts again.

So the question is, which part is most likely to be the culprit? It's a fresh XP install, so no malware. CPU and heatsink are fine with good thermal compound applied, and the fan is working fine. The power supply fan is working. The motherboard is old but not ancient, and never gave me problems before.

My guess is the psu is starting to die, but I'm just looking for opinions before I go buy a replacement. Any thoughts?

Boot to the recovery console and run chkdsk /r

The fact that autocheck runs on restart would seem to indicate there may abe a dirty bit - let's make sure it isn't something as simple as that.
