- 1). Boot the computer and read the "POST" (Power-on-self-test) as you boot. The "POST" is the hardware verification process that takes place before the computer boots the operating system. During the "POST," your graphics card and other hardware details are listed on your screen for quick preview. Press the "Pause" or "Break" key to freeze the screen and take note of the graphics card details.
- 2). Access the "Device Manager." This is where the installed hardware devices are listed. Click "Start," "System and Maintenance" (Windows Vista) or "System and Security" (Windows 7) and then "Device Manager." If you have Windows XP, right-click "My Computer" and select "Device Manager." The graphics card name should be listed under "Display Adapters."
- 3). Install a third-party software that will help you determine the name, model and version of your hardware devices, including your graphics card. Download the software from the Internet and install it to your computer. Refer to the software user guide for instructions on how to use the program.
- 4). Open the computer casing. The name, model and version of the graphics card is often engraved or printed on the surface of the card. Refer to your computer manual for specific instructions on how to open the computer casing. The graphics card is the one that is directly connected to the monitor port at the back of the computer.
