Hello,
Thank you but it still doesn't work. The PC shutsdown. It's not overheating(I play game that are more demanding: LoL,GTA,Far Cry 3,Call of Duty World at War. BL2 etc.) I think it's that happen's only with Paradox games(I had the same problem with Crusaider Kings 2 but it's gone now). I buyed M&B a long time ago and i could play without Problem's.
What could it be?
