Yeah, what Y-Phil said...try the studio drivers and always install with the "clean install" option.  (It's under the non-automatic choice in the driver installer).  They're usually more stable, though I could not get them to play nicely with some Greyscalegorilla plugins and had to revert to the game ready drivers, so YMMV.  But try them both and use the more stable one, the studio drivers will only cost you 1-2% game performance if any, it's worth it if they're stable.
