MoBo: Asus P5AD2-E Memory: CORSAIR 512MB 184-Pin DDR SDRAM DDR 400 (PC 3200) Video:GeForce 6600 GT Processor: Intel pentium 640 3.2 GHz PSU: Aspire 500 Watt My computer would Suddenly turn off. not restart, just off, When I would play my game (World of Warcraft) or Webcam with my friend. It would not do it immediately, it would be about 5-10 minutes into whichever one I was doing, then turn off. When I go to turn it on again, It would turn on but not boot, then shut off again. It would not be able to boot again for another 10 minutes or so. Sometimes, but not all the time, when I am able to get it to boot again, it says it's over-heated. Other times it will Say "Overclocking Failed". other times after turning it back on it runs completely normally. I have cleaned the extremely thick layer of dust on the heatsink and all fans in the case. Checked the memory and made sure there were no physical obstructions of any kind... it's just frustrating I can't do the things I like to do on my computer. I'd kick it... but even though that'd make me feel better for a little while, it'd make the problem worse.
