I have the same problem: game freezes randomly, I get a black screen and can't do anything. Have to reboot the pc. Sometimes even my gpu ramps the fan up to max rpm. This only happens with this game and its very random. 2 days ago it didn't happen at all, yesterday it happened once and today it keeps happening every 30min or so :/ I've tried running it as admin, setting permissions, different drivers, even beta drivers and nothing seems to work. Its unbarable today. Specs are: Intel Core i5 3470, ATI Radeon HD7850, 8GB of DDR3 ram. So I guess I'm more than capable of running the game...
