Well this just started happening not too long ago, I mean I beat the game awhile ago but the screen was fine and now that I am trying to play it again it looks like so:

You can't really see but the bottom is cut off and the bar at the top goes around except on the right side and cuts off at the bottom, And when I go into graphics options nothing will work I turn windowed mode off and it looks like absolute crap, so I am asking for some help here guys :P
