Hey. I've a very annoying issue with my computer crashing. Mostly it's whenever I'm playing a game, so far I've been playing Call of Duty: MW2 and World of Warcraft. It happens like this - I startup the game, and it runs fine for 2-3 mins. Then the screen just freezes, and nothing happens. I'm able to power it off and start it up again. Sometimes it even crashes while loading windows. I had a similiar problem before I bought a new motherboard - because we could not figure out what was wrong. I upgraded the motherboard, and everything was running great for a month. I've tried to test the RAM - but it seemed like everything were okay. I haven't tried to test the graphic card, or the processor. Specs: OS: Windows 7 professional x64 MB: M2A74-AM SE RAM: DDR2 - 2x 1Gb GPU: ATI Radeon HD 3870 CPU: AMD Phenom Quad-core 2.2 Ghz I've updated the graphic-driver today, and I've flashed the BIOS a couple of days ago, to see if any changes appeared - nothing. I hope you can assist. Regards.
