Alright, it first time that I run the Counter-Strike: Global Offensive on my young sister's PC. And I got a surprise. Those black and such shadow like things block my whole screen in menu. When I play game it will either turn red and white or green. The strange thing is that my old sister's PC does not happen. And Both PCs are same model.
This also applies to the game Warface. But not for Left 4 Dead 2, Counter-Strike: Source and such.
Anyone have idea how this problem calls? Because I don't know a proper word how this problem calls.
