When it comes to my nVidia drivers, I invariably have problems with some/most of the latest versions, (artefacts, random graphic crashes, lock-ups, etc),with the result that I always un-install them, and revert back to my Trusty Drivers which were supplied on the CD which came with my Card when it was new...

Latest is not always the best!...
