Blender interface turns into blocks!!?

Does anyone know why blender is doing this under windows 7 x64?

(UPDATE) It seems that when I have blender defaulted to open on another screen other than my main windows screen that is when everything goes out of wack. Just something interesting. It may be my graphic drivers I have an ATI HD 6970. Luckily that is going away soon I have a GTX 680 Superclocked on the way.
