Hey all, i seem to be having a problem with my pc and i think its the card. I can run 3DMark06 just fine, but cod4 is the problem. On some levels its fine, but on others, the game crawls at 35 fps and stutters like mad. Its almost as though its freezing and then starting again. The all of a sardine it just freezes completely and then i have to restart the pc manually. This is now getting highly frustrating. I have tried different drivers and i removed the old ones using driver sweeper. I have the force3D card that comes with the arctic cooling, so i doubt its overheating. Whats going on here?
