First boot into BIOS Setup (F2, Del, esc, or whatever key Toshiba uses)
and check the settings for the display and the video adapter. Anything
having to do with panning particularly. Also, check that you haved the
correct default monitor (laptop display panel at 1024x768 if that is
native) in device manager. It might have somehow become 1280x1024 and
the video adapter is confused about the size and refuses to pan. Also,
if there is a Toshiba setup utility for things like port settings,
mouse, display, etc., you might access that although generally (based on
older Toshibas) it simply accesses the same settings as BIOS Setup.

If you find nothing there that helps, then try removing the video
adapter itself (not just uninstalling the driver) and its software (if
any) from add/remove programs. Reboot to standard vga and check device
manager-view hidden devices - for any remnants of anything nvidia and
remove. Again check that the monitor is correctly reported as 1024x768.
Reboot once again and reinstall the video driver and software exactly as
the readme or release notes require.
