I ran into this problem after I tested the SoftQuadro drivers with win2k.
It seems that when I uninstalled them they left a behind an incompatible mix
of driver files. Maybe you have a similar problem? To remedy I think I
uninstalled the video drivers, manually cleaned out any leftovers (search
WINNT for nv*), and reinstalled the drivers (pick up the latest drivers for
your adapter from nVidia's website.)

Can you rollback to a point where it is working?
