Line of dead/semidead pixels

I am useing a laptop, and sometimes when I am using it, a horisontal line of pixels, 1 pixel high and the width of my screen (1280 pixels) across, would just turn white, randomly, and it mostly happens when I am playing games. It goes away most of the time if I shut my computer down for a couple of hours or just adjust the physical position of the screen (tilt).

What is going wrong, it isn't a program because the pixels stay white even while it is shutting down.

 

Hi, BrynTheSkits.

Have you tried looking for updated graphics-related drivers for your specific laptop model at the laptop manufacturer's web site?

 

Yes, I have looked on the manufacturer's web site and there have been no new driver updates.

Also, the problem seems to be now permanent, I have turned on my laptop 3 times and the line has appared and stayed on the screen from start-up to shutdown.

The line goes dark gray and light gray depending on the image on the screen behind the pixel, but not totally white or black.

UPDATE: There are now 2 of these lines.

 

Thank you for your response, I think I have eactly the same problem, except the lines on my screen are horizontal. Would that make a difference in what was causing the problem?

 

Yea, I too was thinking it is a contact problem, and I have no idea how to correct/reconnect my screen, so I will probably have to take it to a technician to see what he think the problem is and if he can fix it.
