Replacing the Graphics Card in a G4

Whether you are upgrading the video capabilities on your Mac, or replacing a non-working video card, installing a graphics card in a Mac G4 is a very simple process. No special tools or technical ability is required. Different versions of the G4 have different graphic card configurations, but this information is universal across all G4 models.

Things You'll Need

• Mac G4
• PCI video card

Instructions

1. 

   Shut your computer down, and unplug all cables and disconnect any peripherals.

2. Open your G4 by using the "O Ring" located on the right side, allowing ample room for the door to swing open without hitting anything. Once the Mac is open, lay it on its side, with the door swinging up.

3. 

   Locate the graphics card inside the Mac. You can see where it is by locating the video port on the back of the Mac. Gently tug on it to remove it. You should pull straight up, and not wiggle it or twist on it. Avoid touching any of the elements on the inside of the computer.

4. Remove the protective static wrapping from the replacement graphics card, and snap the card into place in the vacant slot. Confirm that the card is properly seated by making sure that it is level on the top, and that that one end isn't higher than the other.

5. Repeat Steps 1 and 2 in reverse order, and then close up the computer, attach all the cables and peripherals and turn the computer on.

6. Confirm that the display works with the new card. Configure the display by opening "System Preferences," and then "Display," and change any settings there.

Tips & Warnings

• The G4 is an older model, so remember that before committing any money into repairing and/or upgrading it.

• The PCI slot covers are often razor sharp, so use care when handling.

• Static electricity can destroy computer components, so use a static strap.
