Blank screen with new video card agp 7600gs?

I understand that you had a 640x480 screen with the new card at first, which went blank during driver loading. What I'm not clear on is, after you went back to the old card and uninstalled the new drivers, then went back to the new card, did you ever have any video through the VGA again or did it stay blank after this? If it stayed blank, you probably have a bad card. If it still worked in 640x480 mode, then you may have the wrong driver. In either case I'd talk to tech support and get a new driver or an RMA.
