Flashing black stuff where task bar would be in some games

Hey guys. I get this really annoying graphical bug sometimes with fullscreen games, where the part where my taskbar would be flashes black with stripes of actual screen still visible. Only got the problem once I got my new graphics card, a Club3D 7950royalQueen.

It's really annoying. Anyone know how to fix it?

I was about to say printscreen lol

 

Try complete unistalling your drivers and install the lastest drivers or a pervious one that was working
