Hi i am running the below system, most games run ok, but i have now hit a brick wall with Call of Duty Black Ops II, and that is when i run the game, My system Freezes and then resets and upon recovery says ot has recovered from a serious hardware error, the Whoscarshed report, says it is a WHEA error that crashed the system, and everyone one i have asked has said it is a Graphics card problem that causes the particular error that is reported.

Help Please....
