I installed Vista (don't say anything, I had an extra HDD around) and then first went to DL the new drivers from nVidia, 97.46. Ever since, I have been getting frequent graphical glitches upon leaving the computer idle. I ran DXDiag and it says that I have DX10 installed.. But I know my card isn't capable, Can someone help me get back on DX9 so I can do things again?
