Ok so I have been here before but with a different card....
When in game I get an error saying display driver not compliant with microsoft windows. This happens after freezing of course. So I Unistalled all applicable Nvidia Drivers through CCleaner. Dx9 good, updated everything ect. I installed/ updated and went to run a stability test check and got this message: EarthDx9[1007]-Error. So I thought what the heck is that?? I put in BF2 and the computer spun up but would not start the game. Is this a PSU problem? I am thinking maybe, I wanted to check Temps while in Game but couldn't because it didn't start up. So I ran Prime95 and it passed. Then I ran the Dx9 Checks through dxdiag-GTG there too. Everything in Device Man. looks up to code. Anyway something is preventing this card from running at full potential. Any ideas would be great.
