When I upgraded to Vista Ultimate, Windows put in it's crappy, wrong driver for my e-GeForce 7900GS, claiming that I had the 512Mb version (which I don't ), and I have not been able to overclock with these as well. I downloaded the 32-Bit version for my 32-Bit Vista, and when I install them, my screen goes blank....no signal at all whatsoever. I have tried downloading it another time, and the same thing happened. I had to go into safe mode, which worked, and uninstalled the non-working drivers with the bad one . Can anyone explain a fix for this?
