Hi, I have an nvidia 8600 GT. its not giving any display at all. When i start using onboard graphics card, it is showing a new VGA unit for which drivers need to be re-installed. When I try re-intalling drivers for the card, both the cd that came with the card and the downloaded latest drivers are saying that they are unable to detect any compatible card. Have tried disabling/enabling and uninstalling/waiting for fresh detect atc. from the device manager. Any help would be appreciated.
