Images display broken

[Baked Potato]

Hi guys,
Hope to get some help here if possible please..
My Photoshop CS 5.1 started displaying images/files kind of broken (see the attachment). I tried to change the amount of memory usage (all I could think of) and it did not help. The images show broken in tales, I scroll them up and down and the keep doing it in different places. Any help would be appreciated please. Thank you!

you can try to turn off the use of the Graphic processor,
and see if that helps ( then you could try to update the Graphic driver)
