Upgrade and Configure a Motherboard

Last Updated on Sun, 19 Feb 2023 | Operating Systems

To upgrade or replace a motherboard, you might have to replace several other components, such as the CPU, heat sink/fan assembly, and RAM. Figure 11-14 shows an example of an old motherboard and a replacement/new motherboard.

Motherboard Operating System

A new motherboard must fit into the old computer case. The power supply must also be compatible with the new motherboard and be able to support all new computer components.

You should begin the upgrade by moving the CPU and heat sink/fan assembly to the new motherboard. These are much easier to work with when they are outside of the case. You should work on an antistatic mat and wear a wrist strap to avoid damaging the CPU. Remember to use thermal compound between the CPU and the heat sink. If the new motherboard requires different RAM, install it at this time.

When it is time to remove and replace the old motherboard, remove the cables from the motherboard that attach to the case LEDs and buttons. They can have the same labels, but there might be minor differences. Make the appropriate notes in your journal to know where and how everything is connected before you start the upgrade.

Note how the motherboard secures to the case. Some mounting screws provide support, and some can provide an important grounding connection between the motherboard and chassis. In particular, you should pay attention to screws and standoffs that are nonmetallic. These can be insulators. Replacing insulating screws and supports with metal hardware that conducts electricity can have disastrous results.

Make sure that you use the correct screws. Do not swap threaded screws with self-tapping metal screws; they will damage the threaded screw holes and might not be secure. Make sure that threaded screws are the correct length and have the same number of threads per inch. If the thread is correct, they will fit easily. You can make a screw fit by using force, but you will damage the threaded hole and the screw will not hold the motherboard securely. Using the wrong screw can also produce metal shavings that can cause short circuits.

Note

It does not matter whether you replace a flat head screw with a Phillips head screw, as long as the threaded part of the screw is the same length and has the same number of threads.

Next you should connect the power supply cables. If the Advanced Technology extended (ATX) power connectors are not the same size (some have more pins), you might need to use an adapter. Connect the cables for the case LEDs and buttons.

After the new motherboard is in place and cabled, you should install and secure all expansion cards. Check your work. Make sure that there are no loose parts or leftover wires. Connect a keyboard, mouse, monitor, and power. If there is any sign of trouble, you should shut the power supply off immediately.

Do not forget that an expansion card can have the same functionality that is integrated into the motherboard. In this case, you might need to disable the on-board functions in the system BIOS. Use the documentation that came with the motherboard to learn what BIOS adjustments might be required.

Lab 11.4.1: Install a NIC

In this lab, you install a NIC and disable an integrated motherboard network adapter. Refer to the lab in IT Essentials: PC Hardware and Software Labs and Study Guide, Third Edition (ISBN 1-58713-198-6). You can perform this lab now or wait until the end of the chapter.
