It appears that there was a new driver released for that video card on November 15th. Here is the link:
Try uninstalling the older driver and then install this driver.
If this does not resolve your issue, try creating a new user profile on your machine, log into that account, and test for the issue there. You may be dealing with a corrupt profile.
***Another thing you can try is to uninstall the Nvidia driver altogether and then use the Windows generic driver. I've seen this resolve issues in the past.
