I have an NVIDIA graphics card. Windows recently forced an update with did not install the graphics driver correctly. When the system boots up, I see nothing, the screen is blank. I put in the restore disk, set the restore point back, and rebooted... everything worked fine. The system, however, updated again, so when I tried to reset the machine to the previous restore point, it was gone... I am stuck with either dos from the Vista disk, or no view of anything. Save mode seems to hang at null.sys so I can't get safe mode to work either... any idea how to set up a system video driver from dos?
