I was wondering if anyone knew which file or files are needed to install video drivers. I deleted something I shouldn't have...actually, I saved what I deleted, so I have the file. I just don't know which one I need to put back. Let me explain the symptoms. If I go into safemode, the screen looks all fuzzy and off-colored, like I need to degauss my monitor. And I can't update my video drivers. When I try to update from nVidia I get an installation error. When try to update the drivers from Windows Update it fails to install.
