I have 3 video cards:
ATI 9600XT
nVidia 6600GT
ATI X1650 PRO
I've had the ATI 9600XT and the nVidia 6600GT since the beginning of time, I know they both work. I bought the ATI x1650 PRO today. I got home, and took out the nVidia 6600GT that I was using, and put the new ATI card in. All direct3d tests failed, POL would open with distortions and pixels all over the place, and VERY laggy. I thought I had a bad card. So I put in my old ATI card...same problem. At this point I'm thinking I broke some shit in my computer, so I put the nVidia card back in. The nVidia card works...
Why is my computer all of a sudden rejecting ATI cards Q_Q.
(All video cards were installed with proper software and drivers, and "Driver Cleaner" was used to remove all files before installing)
