So today, I went out and got a 7600GT to replace my aging 6600 (yes I know the DX10 cards are coming, but the 6600 was just unacceptable.
Anyway, I go and put in the new 7600 and when I go to start the computer all I get is a black screen following the Windows XP startup page. The login screen would never show. So, I put the 6600 back in the computer and the same thing happened. I then booted the computer from the XP disc, and I got into the UI with the 6600 installed. So, I installed the drivers for the 7600 thinking that it was a driver issue, shut down the computer, and then put the 7600 back in. I got into the computer once more, configured a few things, and then was prompted to do a restart. I got the black screen again. I put the 6600 back in with the XP disc, and I still got nothing. I'm really frustrated right now and any help is MUCH appreciated.
