The appropriate driver for your card can be found by visiting the computer manufacturer's website and identifying the drivers for your computer model...
Or visit the nVidia website and download, then install the appropriate driver for your video or audio card identified as nVidia.
Hope this helps.
I was trying to uninstall programs I thought I wasn't using, and thought that because my computer wasn't allowing me to update for "nvidia" that I could just eliminate it. How do I reinstall it back?
