Updating video card in windows xp
Updating drivers is also a great troubleshooting step when the device is having some kind of problem or is generating an error, like a Device Manager error code.
You might need to update drivers in Windows when a new piece of hardware you've installed doesn't work automatically or maybe after upgrading to a new version of Windows.
Nvidia and ATI are the two main video-card producers, and they constantly come out with new drivers for their hardware. The driver download should come as an executable file that starts an auto installation process (or a zipped file that must be extracted to produce the executable file).
Follow the instructions of the auto installer, then click "Finish." Test the device.
If you have a brand-new video card, it will have an install CD with drivers.
If you do not have a CD, search the website of your video-card maker for driver support.
