ATI 5870
Ran fine for a year. Something happened and now if ATI driver is enabled get black screen as soon as Windows 7 (and 8) gets past splash screen.
Runs fine in generic VGA mode. BIOS diagnostic for video card (Dell XPS9100) checks out video without any perceived problems. Can't find ATI specific diagnostic.
Puzzled. Is my video card shot.
