I would simply uninstall the driver in the normal method. Use Driver Sweeper from www.guru3d.com
to further clean all NVIDIA stuff.
Extract from the latest driver download to C:\NVIDIA. Close installer after this happens.
Reboot to safe mode and install only the driver using the device manager.
Test like this and see how it goes.
I'd like to see these drivers get updated as well:
