I recently installed an MSI N9600GT graphics card, and installed the NVidia command center program so that I could download the drivers. I let the program auto-detect my card and proceeded to download the suggested drivers for it.
I had read online about the black screen problems, and so I opted to perform a "clean install" of the drivers. Initially, I had a window with a loading bar, then the screen went black and nothing happens. No mouse cursor, nothing.
I tried to get the card to boot into safemode for Windows 8, but that too did not work, just more black screen.
My onboard card works fine still. Is there anything I can do?
