Hey guys... Well this is a new one for me. Computer has started randomly shutting itself off on me. I'm really torn on whether I think it's a hardware problem or not though. It seems to happen regardless of what the computer is doing. Idling in windows it will eventually happen, however I can quicken it by starting something like WoW, or the SC2 beta... Booting into safe mode it happens eventually, again quickened by doing something such as running a virus scan. However, booting into BIOS doesn't seem to cause an issue (I've let it idle in there for about 30 minutes or more). While in BIOS, the temps are all within ranges and lower and I have all default settings (no OCing). So I'm really torn on this. Could it be a PSU voltage problem that happens when the computer tries to draw more from the PSU? CPU issue under heavy loads? Bad driver somewhere (seems unlikely.. but I'm quite lost). Specs as follows... Windows 7 64 Ultimate (all updates current) EVGA nForce 780i SLI mobo (possibly outdated driver... however this just started happening with no hardware or software changes... Highly unlikely, but on list of things to try) BFG 8800 GTS 512 (current driver) 8 gigs patriot viper mem OCZ PSU (model OCZGXS700) Seagate Barricuda HDD ASUS DL DVD burner Pioneer DL DVD burner I'm sure I'm forgetting something... Any ideas guys? Any tests or anything to try to narrow this down a bit that I'm not thinking of? Thanks in advance!
