For the past few weeks my laptop (Fujitsu) screen has been flashing black with white horizontal lines from time to time. This lasted 2-3 seconds until I hit any key or the mouse and it stopped. Today however , as I was online it flashed black with the lines and stayed that way for hours despite my trying to re-start , unplugging etc... Then I turn it on twenty minutes ago and it's back to normal.
Anyone know what could be wrong?
