Even though you've given limited information, some general tips may help your computer. Obviously exit out of the games your playing and other unnecessary programs you may have running idle. After you've done that, restart your computer and then wait a couple of minutes, then open up your game and see if its still lagging. If it is then it may be a problem with your computers ability to process the game, possibly.
Ok I solved the problem. I did a system restore. I needed to clean up my computer any way. I asked my brother who works for a computer company and he had no idea. During the picture nothing was open. It was just well my computer was sitting there untouched. It was probably a virus that norton missed or something. Oh well problem solved.
