If you are using Windows Vista, there is another version of Intel GMA 950 driver for Windows Vista available for download on this site.

If you have no idea on how to update the GMA 950 Windows XP driver, the easiest way is to use DriverScanner which will help you identify your Intel GMA 950 model information correctly and then locate the most recent Windows XP driver for it.

Besides making sure you are using the above chipsets, you are advice to have at least 1G of system memory on your system. This is what Intel is telling us but I doubt it because I think even with lesser memory, say 512 MB is sufficient to use Intel GMA 950 efficiently.

Installation of this Intel GMA driver is simple. Double-click the exe file you downloaded and specify a location into which the driver files will be extracted. Click Unzip and the files will extract. Click OK on the next window, then click Close. Simple, huh.
