If you want to upgrade a motherboard, free up your schedule because this task can get very frustrating and time consuming. First, you have to remove most of the hardware that sits on top of the motherboard. Almost every one of those devices plugs directly into it. Horizontal computer cases like the Aptiva 2156 case make this even more complicated because of the small amount of space in which to work.
Instructions
1. Remove the monitor from the top of the computer. Unplug its cables and remove the VGA cable attached to your computer.
2. Remove all cables from the back of your computer.
3. Unscrew the top rear screws and remove the casing panel by pulling it back gently and lifting it from the back part at an angle.
4. Remove the power supply by unscrewing the screws around its edge in the back. The power supply is a large box on the rear at the left or right with a large fan sticking out behind it.
5. Disconnect all cables leading to the motherboard.
6. Slowly unscrew the motherboard at all points where it's mounted on the chassis.
7. Remove the motherboard from the chassis by pulling it back slightly and then upwards.
8. Remove the CPU from the motherboard's CPU socket located on the side opposite the exterior connectors. Pull the lever from the bottom of the socket and then simply pull the CPU out.
9. Place the CPU on the new motherboard, unless you plan on using another CPU or your current one doesn't work with the new motherboard's socket.
10. Mount the motherboard and screw it on the case using the screws from the old motherboard and the chassis supports.
11. Place the power supply back in the case the same way you took it out and connect all the internal cables.
12. Reassemble your case and place the external cables back in their respective places.
