I finally unloacked my driver signing features on Vista since I would try to OC my video card. After OC'ing my HD 3870 to just about over 800MHz core clock, I took the clock for a test drive on Crysis Warhead, in Adapt or Perish levels. After playing the levels, i exited Crysis in order to check my temp readings. Out of nowhere, I get a BSOD saying that I crashed because of my newly updated 9.5 drivers, and my temps were running at stable readings. I decided to check in at 3DMark Vantage, clean. Spend an entire night on L4D, clean. F@H, clean. So after all of that, I played other levels of Warhead just in case, it seems that I m only experiencing driver issues on just Adapt or Perish and Frozen Paradise. How should I proceed?
