The sims 3 PLZ HLP! :3?

I'd try by changing the the resolution of the game, in the options menu. also try changing the graphics from low to high, in the options menu. if its not on low then it might be that your computer doesn't have a high enough flash drive (i think its flash drive, or graphic drive) well any way check the requirments on the back of the sims 3 box. if you don't have the requirments you can't change it.
