Hello I have an HP Nc6400 Notebook, it used to work fine but one day when I was watching a movie, the display went black, i restarted and it worked that day, after it whenever I turned on my computer it worked for 5 mins and after that then screen used to go black, but now whenever I install my video driver (Radeon ATI) My screen turns up, and it doesnt show anything but weird lines. GG.
