Just uninstall them. Just go into the display properties and change the video adapter to like the generic PCI vga adapter. Then DO NOT RESTART. Instead, go and open up regedit. and go to the following key:
HKEY_LOCAL_MACHINE\Software\
and look for the folder NVIDIA CORPORATION.
DELETE that entire folder/key.
Then close regedit and REBOOT. then afterwards, your display will be all scrwed up cuz it's only using like 16 colors or something cuz of the generic pci vga driver. So then go ahead and install the 5.22 or 5.32 drivers.
