Go to Gateways site and download your drivers for every thing, and you will be back in business.
You need to load the mother board drivers. They should be on a disk that came with the machine. If you don't have the disk, go th Gateway's web site. Under Support, do a search for you computer model and download the drivers.

You will also need to load the drivers for any add-on cards that you might have installed.
