More about display driver freezing play games
  1. I've seen this happen. Most the time it's overheating.

    You might want to set things back to stock if you are OCing. I'd also make sure to blow out any dust and make sure there is good air flow. You might consider underclocking the ram and or CPU to test. If you underclock it by a good amount and still have a problem it could be related to poor power or some other problem.
  2. would that make it happen only when im playing a game tho? ive never seen it happen any other time, even watching videos and everything it doesnt happen
  3. What game where you playing (multi/single?) and what version of catalyst are you using?

    I had a similair issue with bfbc2 and reinstalled punkbuster as well as uninstalling catalyst 11.4 for 11.3, this seems to have fixed it.
  4. I also have this problems, mostly in the Crysis games though.

    I have custom fan settings on my GTX470's in SLI and still have this same "freezing" problem.
