Everytime I play a video game on my computer, within 10 - 40 minutes into it, my computer completely freezes. My monitor displays what looks like static or white noise that's usually red, green, blue or yellow - my speakers also emit a buzzing sort of sound when this happens, the exact sounds and colors usually depends on what was happening during the game.
This happens in Call of Duty 4 and Bioshock. I tried re-installing CoD4 but it fixes nothing, and ran Bioshock in windowed mode, and again the same thing happened.
I've also tried increasing the voltage on my memory up to +0.3V but that again didn't work.
This problem only occurs during those games, and gaming is the only highly CPU/memory intensive activity done on this computer.
Any one have an idea?
