Not technically correct. If you go into 'Control Panel' and access the
correct logs you will see what has transpired when the driver was
loaded. Most Window users do not want to be bothered with the details
of what happened; they just want it to work (actually, not a bad
concept). Think about it; if Microsoft actually displayed by default all
error messages they or the OEM would probably be inundated with
frivolous requests for support.

I had a friend who used nvidia. They never complained about it. I will
see if I can find out what model and how they got it to work.
