Whenever I try to play any game using my Maxigamer PCI video card it always causes the game to freeze after 2 minutes, not just the game but the entire computer just...stops. I was wondering if this is because of the video card overheating. Or could it be my CPU, even though I have a CPU Fan for my speed processor. They had freezes under tech support, but I did that plus I called tech support and they didn't help.It is an 800MHZ Athlon, any suggestions?
