cod 4 at my laptop... (fps drop)

well now i removed both gpu drivers and installed only intel video driver it works but im without Amd driver xD i think it will do bios thing again when i try to install amd driver thats so complicated

Ok the bug is btw amd catalyst and intel hd graphics. when both installed screen blink twice after third blink it goes to bios.... same as image i put b4

I've reinstalled windows but still fps drop... one second= one fps drop,
FIX = Alt Tab to desktop then alt tab to game.
