Hi guys,

My computer is with SAMSUNG LCD 932GWE+. The operating system is Windows 8 beta. It worked well this morning. But just now when I rebooted it, there is a black line, lateral, from left to right, straight, about 1mm width. The black is also only about 1mm to the fringe of the screen. And the 1mm space can display normally. But the mouse cursor can only be moved to the bottom of the black line and can not be moved to the upper side of the line. I have updated the graphic card and reset the plug, but they changed nothing.

Then I do not know what to do next. Pls do me a favor!

Thanks a lot!
