I just bought a ATI Radeon 8500 and played a lot of games with it including Ghost REcon, Ballistics, Civilisation III, Counterstrike and TEam Fortress Classic. I played TFC(Team Fortress Classic) for about one hour and suddenly my computer switched off by itself. After I switched it on, I played CS, once I entered the game and started, my computer rebooted! why!!??! and i have NO problems with other games like avp2, ballistics, civil 3 and etc. I have the latest drivers from ATI. What's wrong?My best guess is it's overheating but cant it withstand the heat?
