MY wife's laptop had this problem this morning which I couldn't correct before leaving for work.  It was working fine last night and early this morning, however, after working on it this morning, the screen went all crazy.  It was totally illegible with a white background and vertical lines.  I rebooted it and when the logon screen came up, the screen was still white but I could make out some of the graphics, like the logon icon and such, but they were really distorted and there was almost no color.

 

I  tried rebooting several times, but it did not fix the problem.  I didn't have time to hook it up to the desktops monitor to see if the video card was OK.  Any ideas what this could be? 

 

I'm looking at replacement LCD screens and they are not cheap.  If its a video card, I can just replace that.  However, I am pretty sure this cheap laptop has it integrated into the main board.

 

Any help is appreciated!
