sapphire 7850 random small areas of pixelation

I have determined this to be a graphics card or GPU driver probelm
I am running a catleap 27' with the 7850 and using teh dual dvi cable that the catleap came with.
Randomly about every few seconds small areas on the screen become pixelated with little boxes of colors.
I went to device manager and disabled the display adapter labeled "AMD Radeon HD 7800 Series" and this took care of the problem. So i would assume it is a probelm with the card or the driver. Anyone have any ideas??
BTW: as soon as I move the window or move another windows over the effected area it goes away.

Here are a few pics of my screen so you understand better what I am talking about.
