-------------QUICK INFO

Model: LG P1-KB11A (LG Electronics)
Type: Laptop
Graphics card: ATI Mobility Radeon X1400



-------------PROBLEM DISCRIPTION

The system froze as I was watching a high resolution video in VLC media player. Usually, if the room is cool, I have no problem watching high-res video. However, if the computer has been on for a few days and is warm, the video stream will start lagging.

This was exactly what happened right before the system froze. After a reboot, the display was completely black.

I booted in safe-mode and found that the display was split in half.

After I disabled the original video display driver, Windows booted normally but still with a split display.

Whenever I try to install any other driver than the Windows Standard VGA driver, the display turns black upon reboot.

Hello, i often overclock my graphic card and this problem always happens when i set my memory clock speed too high so probably your problem comes from graphical memory. What you can try to do is to download a graphic card overclocking software like ATI tray tools if you're using an ATI video card and underclock (means reduicing the frenquency)by like 50-100 MHz your graphic card memory and try to restart your computer, maybe it will work.

In my case, the problem is solved when i reduice the graphical memory frequency and make my computer sleep/restart.

Good luck.

One thing that I found interesting was that the screen was shrunk to one side. It is not a matter of half the screen not being displayed, but it is all being displayed on half the screen. You still have a fully functioning taskbar, but it doesn't span the whole screen.

What does your resolution selection screen look like? What does it say?
