So after 3 hours my monitor turns off and turns back on if I move the mouse. Tonight I came back to my comp and turned it back on and a quarter of an inch of the lcd screen right above the dock kind of scrambled a bit, as if it were snow on a TV. This occurred while the screen was "warming up" and getting brighter and then it stopped. It only happened once (that I know of) and it only lasted about 1-2 seconds. What does this mean? Anyone have a similar instance?
