Vista - Deleting Video Drivers from Command Prompt?

I recently upgraded the video driver using the "Automatically find my driver" function on nVidia's website. Unfortunately it doesn't seem to agree with my 7950GX2. After installation, windows loads, but only the mouse cursor is visible, although I can still interact with the things I can't see. For some reason, no restore point was set by vista before the driver update, so I can't roll back. I know it's the drivers because I did the same exact thing with a separate Vista partition on the same computer and was able to roll it back. What I'm wondering is how can I go through the command prompt (which is the only thing I can get to show up even in safe mode) and delete the corrupt drivers and get my main windows installation back?

Can you boot into safe mode? That should allow you to at least see everything. Then you can uninstall the video card in the device manager, and check the "delete driver software" checkbox and it should uninstall the drivers for you.

Nope, can't even do anything in safe mode except use the command prompt.

WOW that's something I've never run into. Safe mode should only be using a basic VGA driver, not the actual video card drivers.

The video drivers would most likely be located in

C:\windows\system32
C:\windows\system32\drivers


However I'm not sure what they will be named, as I'm running an ATi card.

However you mention a separate vista partition that's working? Can you see the non-working partition when booted into the working one? Would make life a lot easier. If not, at the very least you can navigate into those directories and see what the driver names are, then go back into safe mode on the corrupt partition and delete them.

Have you tried hitting F8 when restarting to see if you can get to the DOS menu where it lets you choose an option that starts with vga capabilities only?

Also, are both ends of the video cable plugged in correctly? Discard that, you said you can see everything when you boot with the other partition.
