I accadently uninstalled my Intel extreme graphics driver could anyone tell me how to re-install it?

What is the make and model of the computer?

The manufacturer's web site will have the driver.

It's a gateway Pentium four.

I have two computers and the one that I'm having trouble with cant get on the internet.

Did Gateway give you a driver CD?

Here is gateway's driver page:
