I just got a new PC from ibuypower and i have a Radeon Hd 7990 with a i5-4670k, i have Windows 7 64-bit and everything was fine at first, but the i tried to play games and it gave me a blue screen every time i tried to launch a game. Games like Sniper Elite v2, sleeping dogs and ect... and on top of that it freezes every 10 min on a game and i have to turn my whole computer of then back on. My drivers are all up to date, but im thinking about changing to a beta version to see if it helps. crysis 3 boots up fine and i can max it out nut it freezes when i play over 10 min at a tim. What should i do? Do you think my card is overheated? Should i buy a seperate GPU cooler or something? My CPU is water cooled, and the whole things gets hot on games like Tomb Raider and Crysis 3. Those are the only games ive been able to play so far. And they still get occasional freezes, but not as bad. So please help!
