Computer turns off intermittently
This just started last night. I was debugging some camera code related to a shaking issue and on my last debug attempt the entire computer just shut off. I went to bed thinking that somehow I triple faulted the CPU and all was ok.
When I got home from work I turned the computer on and wasn't paying much attention to it. When I looked back up my computer was off. Booted again and it blue screened. Went to safe mode and removed some startup programs via msconfig and set the system so it would not reboot if it encountered a system error. Viewed the event logs...nothing. Rebooted. Everything was fine until I went into Mercenaries 2. The minute it went it to the actual 3D the computer shut down.
So I'm thinking power issues or video card or virus. Scanned for malware and viruses with Spybot S&D and Antivir. Nothing. Tested Direct3D with dxdiag thinking that if the card was prob. drawing more power in 3D which might make a weak PSU just shut down that dxdiag might cause the system to shut down during a test. All tests passed. Fired up Mercenaries 2 and played for hours and hours - no temp issues (GPU 70 C max) and nothing crazy.
So....what the heck is going on? Is it possible I have something in the PSU that is going out? If so I thought more heat (IE: more up time) would reveal the problem as opposed to it revealing itself when its cold.
The PSU is a 1000W Antec and it's less than a year old.
