what OS u on? and unless you know what ur doing I HIGHLY advise you dont mess with the operating system. Reinstalling should be fine and will probably fix the problem as it looks like your other games can run so there is no problem with running games in general. You could check to make sure your CPU and Video card meet the minimum requirements for the game. They may be on the edge of working for the game and can only run it for a bit before crashing.
