I have just built a new gaming computer and since its been built, it has blacked out a few times. Let me explain what i mean. At random (cannot duplicate on command) the screen will go blank, the audio will turn off but the computer will remain running, with all the lights and fans going. But strangly the only way to turn it off is to flip the switch, because holding down the button does nothing for me. Ive checked power settings, ran virus scans, checked temp files and registry, but see nothing strange. Reinstalled video card drivers from CD but to no avail.
System Hardware.
Motherboard -- MSI 890FXA-GD65
Video Card -- HIS Radeon HD 6950
RAM -- 8g G Skill DDR3
Hard Drive -- 320 Sata (It was from my old computer, completely reformatted though)
CD Drive - Sata DVD Reader
Case - Phantom
Power Supply -- Corsair 750w Power Supply
Monitor -- 19Inch LCD (Also from my old computer, but no issues)
Case Fans -- Top Fan 200mm, Back Fan 120mm. Two Side fans 120mm and One Front fan 120mm.
CPU -- AMD II Processor Quad Core (Black Edition with stock fan)

On a side note ive seen no heating problems at all, Core Temp is loaded and i rarely go above 115 degrees. If you need a event log please give me a link to download one that would be effective or not, im really not sure what is going on with it

I've heard of issues with the Corsair 750W PSU's. Try swapping it out for another PSU of a different brand.
