My screen goes to black and the computer freezes (no actions can be performed, requiring to hold power to turn off to reboot) when playing HotS. Usually happens about 5 to 10 minutes into a game. Doesn’t happen with Diablo III (the other game I play) .
I tried re-installing/re-downloading graphic card driver and reinstalling HotS as well as the Scan and repair function but it hasn’t helped.
