My Geforce 6200 pci will freeze when I try to play a game and the onboard graphics never did that. I know a lot of other people are having the same problem so please help. I know its not temperature because I took off the cover and had a fan blowing on it and it still freezes. I dont think its the psu because other people with 400w+ psu's (250w minimum) still have the same problem. Please help.
