Some computers from major manufacturers are shipped with onboard video. This means the video is integrated into the motherboard instead of being a removable card. You'll need to disable onboard video before upgrading. Follow this link to see how to do this.

After you've picked the right video card for your system, it's time to install it. Here are some general guidelines. If you're unsure about any of the steps involved, consult the documentation included with your new video card. Better yet, try grabbing an experienced user to show you how to do this.

Remove old card

1. First download the latest drivers from the video card manufacturer's website.
2. Remove old drivers. In Windows, check "Add/Remove Programs" for video drivers entries. Also erase any left-over video driver folders that typically end up in the root of the C: drive.
3. Shut down the system.
4. Unplug your monitor from the old video card and open your computer's case.
5. Unplug your computer from its power supply. Also, you'll need to ground yourself by touching your computer's power supply while working inside its case. Doing this will discharge any built-up static electricity in your body and prevent damage to your new card.
6. Remove the screw holding your current video card in place.
7. Remove your current video card.

Insert new card

1. Remember to ground yourself by placing one hand directly on the power supply.
2. Place your new video card into the correct slot.
3. Secure the card in place using the screw you removed from the old card.
4. Connect your monitor to the new card, hook up the power cord, and turn your computer back on.

Configure the new card

1. While the computer is booting up it may recognize your new graphics card and install its proper drivers. Depending on how Windows was installed on your system, it may prompt you to insert the Windows CD to complete the installation.
2. Most graphic cards come with a disc full of drivers and demo games. Do not use this disc as it's likely outdated.
3. Install the latest drivers from the manufacturer's website onto your system.
4. After the new drivers are installed, you'll need to restart your system for the changes to go into effect.
5. Special video cards such as the All-in-Wonder series from ATI may require additional software to utilize some features of the card. In this case, consult the manufacture's website for specific installation instructions.
6. For most users, the default video control panel settings are fine. Do check that your desktop is displaying 32-bit color, the resolution is set to taste, and that your monitor is set to a refresh rate of at least 75 Hz for CRT displays.

If you discover any problems, such as a continuous beeping sound, then you may have a problem. The manufacturer of your motherboard should have beep codes posted on its webpage. Listen to the pattern of the beep sounds. It will resemble a Morse code pattern that will help you identify possible problems.
