I was getting the odd random restart over the last month, but now its become frequent, every hour or so, i hope it doesn't do it while im typing now.
Well, yeah, basically, it restarts, no BSOD, nothing in event log, so i guess something is overheating.
My PSU is pretty new, so i don't think that is the cause, my CPU is quite old but it seems to be fine, no problems with the heaksink. But my GPU's fan does make quite a quite whining noise (i was concerned at first, but it didn't seem to affect my computer, so i didnt wana fork out cash for a quiet noise), so i think it may be the fan on that, not cooling properly (any way to check).
Basically, how can i find the culprit without switching parts, because i don't have any access to spares, without actually buying them, are there any programs that monitor the computer and collect data when it restarts or something.
Any advice before i risk just buying a new graphics card or fan.
