I can't uninstall the existing drivers. I can't install the new ones. I went device manager and uninstalled the display adapters...rebooted....nothing changed.... I can't even use the PNY driver disk that came with the video card to uninstall or install anything. Keeps saying error before launch and kicks me out of the setup. Does anybody have any clue what is going on here? I've never had a problem updating drivers in the past. Thanks.
