Hi, few days ago i was playing games as usuall (bf3, bf4, titanfall,) on ultra settings with no a problem but 2 days ago i couldnt play bf3 because it started lagging a lot. Okay it is just 1 game. I played another games and after playing 30 mins or more the computer crashes it says "PC ran into problem..." I thought there will be problem in OS so i reinstalled it and clean up my whole harddrive. Now i installed few of my games back (dayz, bf3) and when i started up dayz or bf3 it started lagging a lot! i checked my temperatured and they are okay. Now i dont know what to do so im asking.

OS: Windows 8
