I just got my RMA'd x800 pro back and i was using some old crappy ati mach64 video card with some old diamond viper drivers. It was fine...i completely uninstalled the video card (from device manager) and it was fine. I put the new video card in and booted it up...i tried to install the catalyst drivers but it said it couldnt and maybe i needed some standard vga drivers...windows couldnt find any so without knowing i just disabled the "VgaSave" thing which was under driver properties and rebooted. Now after the windows loading bar goes across it doesnt boot to windows. it just goes black after the "Windows XP" and little thing goes across a little bar as usual but then im expecting a light blue screen with the users name's to come up but nopoe...just stays black...WHAT SHOULD I DO...i cant even back up my files and reformat like this!
