Hey everyone, I've used this site as a reference for quite a while and I was unable to find a good answer for this one so here it goes. I just upgraded my PC as follows Case: Coolermaster HAF 932, MoBo: MSI 785GM-E65, PSU: "CU" 700 watts, 12v1 18-12v2-16-12v3-16, CPU: AMD Phenom II X4 945, RAM: Corsair XMS3 4GB (2X4GB) DDR3 1600. Components not mentioned were not upgraded.
So my problem is that when I'm doing something that taxes things pretty heavily (like playing CoD4) the system will reboot without warning. There is no windows error, no nothing. The system won't post when this happens either it just sits there until I remove the power and plug it back in, then it comes up no problem. I'm thinking its probably the PSU I got, it was far cheaper than the comparable Corsair and Thermaltake at Fry's (probably a reason for that). It may also be noteworthy that I have a Logitech G15 backlit keyboard, when the system would reboot unexpetedly like it did the backlight would flicker, kind of like a flourescent light thats going out until I unplugged the system.
When I'm playing other games such as Crysis or Devil May Cry 4 this does not happen (although I haven't played either for extended periods yet). I can also use the system for normal tasks just fine (I'm typing this on it right now). I can't really think of anything else it could be, the PSU was the only thing I really cheaped out on, and if it was a software issue with the game I would think there would be some kind of Windows error message, BSoD, entry in the event long, something, but there isn't. Anyways, thanks in advance for the help.
EDIT: Sorry everyone I forgot to mention that I'm pretty positive its not a heating issue, I've got both rivatuner and speedfan running and they are all reporting very acceptable temps, cpu stays around 43C and GPU stays around 68-70C. HDD temps are well below this, 20-35 usually.
