Weird slow motion problem FPS

Whenever I play Counter-Strike 1.6 or Battlefield 3, every movement that I do is in slow motion. This goes for my gravity, speed, jumping, shooting and reloading. On Battlefield 3 single player and while viewing a demo on 1.6, everything is in slow motion.

Also to note, whenever I play WoW or SKyrim, this problem doesn't exist. Any words of advice? Ty for your time.

I appologize if this isn't in the right category or sub category. All my friends are really confused why this does happen.

Edit: I already updated my video drivers, did not fix the problem.
