Sometimes when I am playing a game such as WoW or Team Fortress 2, my monitor goes blank and on a few occasions has been slightly different colors. Everything but the monitor appears to contiue running, but nothing responds. The only other noticeable thing when this happens is that the harddrive starts to make a noise similar to when it boots along with a flashing red light on the front of the tower. If I let the computer sit for a minute or two after it goes blank, it makes the "beep" sound when it boots...except it doesn't reboot, so I have to press the restart button to get it running again. This has never happened while surfing the net, writing documents, etc, ONLY when playing a game. It does not happen extremely often, maybe 1-2 times per hour. e-GeForce 8600 GT video card ASUS P5N-MX motherboard Intel Core 2 Duo E4600 @ 2.40GHz 2400MHz Core speed DDR2 2048 MBytes PCI-Express x16 Help would be greatly appreciated!
