Hello, my friend is having problems with his GeForce 2 GTS video card. He gets little white spots on his screen sometimes and also, some games will not run at all or just lockup or the screen will just turn all black. His system setup is a K7s5A motherboard with a 1.4Ghz athlon and 256 mb ram. He is using a 300W power supply. Anyone have any ideas of what the problem is or how to solve it? Thanks in advance.
