How to Replace a Graphic Card
- 1). Determine what type of graphics card is compatible with your motherboard. Most modern motherboards (manufactured after 2006) support the PCI-E interface, which (as of 2011) is the standard interface for the most powerful and highest-performance graphics cards. Your motherboard may also feature an AGP and/or standard PCI ports. You can find out what type of interface your motherboard supports in its documentation or by using a third-party program (such as CPU-Z).
- 2). Select a graphics card that meets your needs. If most of your computing involves only basic Internet browsing, word processing and the occasional DVD, a low- to mid-level card will be more than sufficient. If you watch a lot of HD video (BluRay or streaming) or use a lot of 3D applications (such as games), a mid- to high-level card is recommended.
- 3). Shut down your computer. Disconnect the computer from its power source and power off the power supply on the back of the case. Use a screwdriver, if necessary, to remove the computer's side casing. (Some cases are toolless designs that don't require a screwdriver.) Press your hands against the metal housing inside the case to rid yourself of any static build-up that might otherwise damage your computer's hardware.
- 4). Locate your current graphics card. If the card inside your machine is an AGP or PCI-E card, it will be toward the button of most cases, right above the standard PCI ports. (Most motherboards have these ports clearly labeled.) Open the latch on the right side of the graphics card to free the card; gently pull it up.
- 5). Insert the new graphics card into the appropriate slot. Press down until the card is secure and close the retaining latch. If required, plug a power connector into the appropriate receiver on the card. Reconnect the case cover, plug in the computer, and turn on the power supply. Boot the machine like normal. After your computer starts up, you may be required to install drivers to enable the full functionality of your card. (Drivers are available on the installation disc that comes with the card, or directly from the manufacturer's website.)
