have a HP Pavilion notebook with ATI mobility radeon X600 and everything is fine but recently some marks appeadred on a display. I want to say that LCD is not faulty as I had connected an external monitor and same problem persisted. They appear more and more so now they lay out a chessboard pattern. Is the problem caused by the grapics card or memory on it? HOw to resolve it?
-   I try to play games on my notebook but it doesn't work. I think i need a graphics card driver.

-   My problem - with my thinkpad r40, is that after a 1/2, the display gets really out of focus and then strange vertical tracking lines appear, then the computer freezes. To me, it is as though something is heating up and then overheating and slowly stopping working.

I have uninstalled and re-installed drivers.-   Guest
Yes could be a graphics card problem, try uninstalling drivers through your device manager(right click my computer>properties>hardware tab>device manager)and click the '+' sign on your display adapter, then right click and uninstal.
Reboot and allow windows to find hardware and drivers again.
Other suggestion is normally, there is a facility on laptops to re-install certain drivers from a restore patitition on your hard drive.

i have the same issue...a black scriggly line appeared at the top and gradually over the last couple of weeks has made its way down the screen. This is a new laptop and I haven't taken it anywhere and handle it with great care. Any ideas as to what I can do other that ship it back to Toshiba?
