Every time my friend runs ANY game. His computer crashes. He said, "Just a DRRRR sound and the computer has crashed. No warnings, just complete crash." So what could be wrong? He has the following equpiment: Windows 7 Home Premium 64-bit Intel Core 2 Quad Processor Q8300 NVIDIA GeForce 7100 Integrated 640 GB HDD 4 GB DDR2 memory (RAM) I hope one of you guys have the correct answer to this. He's installed the latest drivers and tried DirectX9 instead of 10 and 11. Still nothing.
