When I turned on my computer this morning, I noticed a black bar around the sides and up/down on my display. The black bars are about an inch on the sides and 1/2 inch above/below. Computer info - i7 920 9gb 1333mhz RAM ATI 5970 Windoww 7 Home Premium running at 1920 x 1080 rez. My CCC is 10.2. Any help would be appreciated. Thanks!
