Open up control panel, and navigate to "Device Manager." If you're using category view, click on "Hardware and Sound", then "Device Manager" under the "Devices and Printers" header.
You should get a big list of all the devices in your machine. Double-click on "Display adapters", then double-click on whatever's under it.
Click on the "Driver" tab, and there should be a button labelled "Roll Back Driver." Click on that and hit yes through any prompts that pop up.

Depends on the card I guess, I just get a download.
