How to Install a Graphics Card Driver
When you install a new graphics card in your computer, it is time to install graphic card drivers so that your system can fully utilize the capabilities of the card. Most often, your graphics card will come with CD/DVD that will automatically install the drivers, but occasionally, you may need to download the drivers from the Web and install them manually.
1). Install the new card in your system by inserting the graphics card in one of the PCI or other expansion slots in your desktop. If you have a laptop, follow the manufacturer's instructions for installing a new graphics card in the machine.
2). Boot up your computer and then click on the "Start" menu.
3). Click on "Control Panel" from the Start menu screen.
4). Click on the "Add New Hardware" on the Control Panel window.
5). Click on the radio button next to the "Yes, I have already connected the hardware" option on the screen if Windows doesn't automatically recognize the new card. If the operating system automatically finds the new hardware, follow the onscreen instructions to install the drivers.
6). Scroll to the bottom of the list that displays in the new window. Click on "Add a New Hardware Device." Click the "Next" button on the bottom of the screen.
7). Click the radio button next to "Install the hardware that I manually select from a list" and then click the "Next" button on the bottom of the screen.
8). Choose "Display adapters" from the list of hardware in the new window. Click the "Next" button.
9). Click the "Have Disk" button on the new window.
10). Browse to the location where the graphics card drivers are located. Click the "OK" button at the top of the screen. The drivers for your graphics card will automatically install.
11). Reboot your computer when prompted for the changes to your system to take effect.
