Updating video cards in laptop computers
Your video card must have a display driver installed in order to do anything but the most basic drawing to the screen.
If you're having any problems with your video card, one of the first things you should do is download the latest display driver, uninstall the current display driver, and then install the new driver you downloaded. There is no point in spending time trying to trace down the cause of video card problems until you've completed this initial step.
If none of the standard fixes work then things get more complicated.
If you're not sure what to do then you should just run through all of them.
If you're running Windows 2000 or XP, you can disable your sound hardware by going into the Device Manager, right-clicking on the sound hardware, and selecting "Disable".But if your video card is crashing or hanging then it's often difficult to find the cause because so many different problems can result in the same symptoms.There's a standard set of fixes which you can try out to see if the problem goes away.Always remember to uninstall your current display driver before installing one.If you don't uninstall first then you can sometimes cause some pretty obscure problems.
