Everything was working fine, but appeared that the 3D drivers were not enable as even a 3D screen saver would run choppy. I went to check the 'Hardware Drivers' and there was an unchecked box next to nVidia 3D drivers box, so I checked it. One file was downloaded, several things installed, and it asked for a reboot.
Once the login screen arrives, all video disappears, even the backlight shuts off. How can I remove/replace these drivers. I can live with only 2D if I have to but no video is not an option.
Thanks a million.
