Stange System Problem

[zod96]

My system is acting really strange. I can use my system for hours, gaming surfing etc. Then out of the blue at total random times my system will reboot itself and then try to power on then off then on then off andjust go threw this endless cycle without being able to boot. If I turn my computer off for a while and come back its fine. I checked my memory with memtest its fine, I ran a HD test on my samsung and its fine. I don't overclock and I haven't changed anything in my system. Would a PSU do something like this? Its a corsair 620 that's about a year old. I'm at a loss here because it happens at total random times its not consistant And their's nothing in the windows event viewer either...

Punting to Motherboards by request.

My idea: check connectors (mobo, video, everything). Refit cards, CPU, RAM etc. Should this fail: disassemble the comp and put it together once more.
Wrong forum btw.

Edit: pay attention to power cable splitters.

I thought I put it in the motherboard forum, I guess I was still a bit alseep If a mod sees this move it pleasae

Diagnosis tree: hardware or software?

Hardware:

Overclocked or tweaked? tweaked memory timings?

Heat buildup, i.e. cooling fans/vents clogged with dust? Includes checking CPU, GPU, northbridge.

Bad capacitors? Any bulging caps?

Software:

Driver issue? Any recently updated drivers, esp video, that are being accessed when your system crashes?

New programs?

Doubt spyware, etc, but, system protected against it?

Addendum: any info from Speedfan about voltages, temps, etc?

Also, I think there are other very good diagnostic software programs you can download for free; also, you can run a CD based linux distribution, and see if running different software also causes problems: that makes a hardware issue much more probable.
