I recently upgraded to Vista, and I have been having some issues with my Nvidia Geforce 7900 GT. What happens is this: I try to run a game, and the screen will suddenly be filled with a mess of alternating green/light green or black/white stripes. Sometimes I will get to the menu screen of a game, and when I change the video settings, the same error occurs. I have looked around a lot, but have yet to find an answer to my problems? Does anyone know what might be plaguing me? I have updated to the latest drivers, and I am positive that it is not my power supply, as I just got a new one. I am not sure where else to look.
