Has anyone had this problem? When I'm playing a PC game after about an hour or so my screen will turn DIFFERENT colors all crazy like, then about 2 minutes later it will lock up and I have to manually reboot the system. Can anyone give me a solution???

Thanks
RobGraphics card is overheating while you're playing the game. Monitor temps while you're playing.

Post a screen SHOT.OK I will do that, I got the fan and installed it my temps are looking good. I will post a screen shot when I get a chance. Thanks for the help...Well still having the same problem, I'm playing AOE3 online and it starts doing the same stuff. When it does it the next time I will take a PICTURE of it and post it.
