Yeah, I understand when Windows elects to use vgasave - something wrong with
the installed display drivers. Though, you'd think that a problem would be
reported in the device manager instead of saying that it is working properly.
Also, the nvidia installer didn't report any problems during installation
either. I even see the screen blink a couple of times during installation
which I usually interpret as its doing something with the display. The event
viewer also doesn't show any problems. So the system doesn't really leave any
clues about why it doesn't like the nvidia drivers. Its like its just stuck
on vgasave.
Thanks for the tip about not stopping the vgasave service. Though I had
already personally discovered that is not a good thing to do *sigh*. Thank
god the F8 key during boot helped to easily rescue me from that little
disaster.
