Nvidia (built and designed) GTX 460. Drivers are fully up to date. I have even tried rolling back as far as 4 driver releases.... No luck.
Have you used DriverSweeper to remove previous versions before attempting to install another? If not, I suggest you clean out all Nvidia drivers with DriverSweeper, get the most current version directly from Nvidia, and try again.
If this fails, you GPU may be defective.
