PC resets itself every 20 minutes or so

As the title says. I have a feeling something's broken inside but I can't think what. First impression was the PSU (it's a good 550W Antec one, about 2 years old) but it doesn't seem to make any difference what I'm doing. About 20 minutes if it's sat at the desktop doing nothing and the same when I loaded up the Crysis demo. It's just a straight reset as if I hit the button on the front, no blue screen or anything. It hangs for about two seconds before it resets too.

I'm going to try reformatting if nothing obvious comes to mind as it's been slowly cluttering up since I last rebuilt it, but it's an enormous pain in the arse backing everything up first.

Temps ?

CPU is 30 degrees C idle, graphics card is about 60 idle and 75 max.

It still crashes exactly the same with the same frequency whether it's idling or maxed.

Just weird its 20mins always.

Yeah, I know. That's what's got me baffled. I did put a new wireless card in a few days ago, but it's been fine with that until last night, when this started.

I'll take it out and try it when I can be bothered, but it's on the floor and heavy

Perhaps it a virus resetting the computer so you can't scan for it? Try safe mode.
