How to Fix a Video Card Driverby Isaiah Turning
Your video card uses a driver, a specialized software program, to enable all of its features. This video card driver may not work if you have recently made changes to your computer. A video card driver could stop working after updating the driver to a new version that is incompatible with your computer, or if you make a change to hardware or software on your computer that is incompatible with your currently installed driver. In both cases, it is necessary to fix the video card driver by restoring it to a previous version or installing a new version.
Restoring a Driver
Open the Windows "Start" menu and click "Control Panel." Click "System and Security" in Windows 7 or "System and Maintenance" in Windows Vista.
Select "Device Manager" underneath the "System" subheading. Click "OK" in the security prompt dialog box if you have User Account Controls enabled on your computer.
Double-click "Display Adapters" to view your video card. Right-click your video card and select "Properties." Switch to the "Driver" tab and click "Roll Back Driver."
Click "Yes" in the warning prompt dialog box. Your screen may go black as the previous driver version is reinstalled. Restart your computer to start using your video card with the correct driver.
Installing a New Driver
Download the driver installation file from your video card manufacturer's website. For example, if you use an NVIDIA video card, go to the NVIDIA website and download the drivers for your operating system and card model.
Click the Windows "Start" button and select "Control Panel." Open "System and Security" in Windows 7 or "System and Maintenance" in Windows Vista. Select "Device Manager" and click "OK" in the User Account Control dialog box if this security feature is enabled on your system.
Click the arrow next to "Display Adapters" to expand the Device Manager listing and double-click the name of your video card. Open the "Driver" tab and click "Update Driver."
Select "Browse My Computer For Driver Software" and click "Browse." Navigate to the driver installation file you downloaded from your video card manufacturer. Select the installation file and click "OK" to continue.
Click "Next" to proceed with the installation. Follow the installation file's instructions to update your video card driver. Restart your computer to begin using your video card with the new driver.
