Identify the mounting holes on the computer case that align with the screw holes on the motherboard. These holes may vary depending on the form factor of your motherboard.
4. Locate the standoffs
Locate the standoffs (provided with the case), which fit into the corresponding mounting holes on the computer case. These standoffs will elevate the motherboard and prevent it from touching the case directly. This helps avoid short circuits caused by metal parts of the Case coming into contact with the motherboard. Do not screw the Motherboard to the Case yet.
5. Install the I/O Shield
The I/O shield, also known as the backplate, is a metal plate that covers the motherboard’s rear ports. Insert it into the rectangular opening on the back of the computer case, aligning it with the motherboard’s I/O ports.
6. Install the CPU
Refer to the motherboard manual for instructions on installing the CPU (Central Processing Unit). Ensure that the CPU is compatible with the motherboard socket. Gently place the CPU into the socket, aligning the notches or markers, and secure it using the CPU retention mechanism.
7. Install the CPU Cooler
Apply a small amount of thermal paste on the CPU, then attach the CPU heat sink or any other cooler according to the manufacturer’s instructions. Make sure it is firmly attached and properly connected to the CPU fan header on the motherboard.
8. Install the RAM
Refer to the motherboard manual to identify the RAM slots. Insert the RAM modules into the slots, aligning the notches on the module with the slot. Apply gentle pressure until the RAM clicks into place.
9. Connect the Power Supply
Locate the main power connector (usually a 24-pin or 20+4-pin connector) on the motherboard. Connect the corresponding power cable from the power supply to this connector. Additionally, connect the CPU power connector (usually a 4-pin or 8-pin connector) to the designated socket on the motherboard.
10. Connect Storage Devices
Connect the SATA cables from the storage devices (hard drives or solid-state drives) to the SATA ports or M.2 Slots on the motherboard. Ensure that the cables are securely plugged in on both ends.
11. Connect other Peripherals
If you have additional peripherals like graphics cards, sound cards, or network cards, follow the manufacturer’s instructions to install them in the appropriate expansion slots on the motherboard.
12. Connecting Front Panel Components
The next part of motherboard installation is connecting the LEDs, buttons, and front-mounted ports on the front of the box. This is sometimes easier to do before you install the motherboard fully in the case. You can trace the wire leads from the front of the case to the appropriate standoffs on the motherboard. These usually include the following:
- Soft power button
- Reset button
- Speaker
- Hard drive activity light

- Sound
These wires have specific pin connections to the motherboard. Although you can refer to the motherboard book for their location, usually a quick inspection of the motherboard will suffice for an experienced tech.
13. Latest Important Details
You need to follow a few rules when installing these wires. First, the lights are LEDs, not light bulbs; they have a positive side and a negative side. If they don’t work one way, turn the connector around and try the other. Second, when in doubt, guess. Incorrect installation only results in the device not working; it won’t damage the computer. Refer to the motherboard book for the correct installation. The third and last rule is that, with the exception of the soft power switch on an ATX system, you do not need any of these wires for the computer to run.
It is advisable to install the CPU, CPU fan, and RAM into the motherboard before installing the motherboard into the case. This helps in several ways, especially with a new system. First, you want to make certain that the CPU and RAM work well with the motherboard and with each other—without that, you have no hope of setting up a stable system. Second, installing these components first prevents the phenomenon of flexing the motherboard. Some cases don’t provide quite enough support for the motherboard, and pushing in RAM can make the board bend. Third, attaching a CPU fan can be a bear of a task, one that’s considerably easier to do on a table top than within the confines of a case. A lot of third-party CPU fan and heat-sink assemblies mount on brackets on the bottom of the motherboard, requiring installation before placement in the case.
14. Screw the Motherboard to the Case and Test it
Finally, install the motherboard into the case fully and secure it with the appropriate screws. Once you get the motherboard mounted in the case, with the CPU and RAM properly installed, it’s time to insert the power connections and test it. A USB POST Card Tester can be helpful with the system test because you won’t have to add the speaker, a video card, monitor, and keyboard to verify that the system is booting.
If you don’t have a POST card, install a keyboard, speaker, video card, and monitor. Boot the system and see if the BIOS information shows up on the screen. If it does, you’re probably okay. If it doesn’t, it’s time to refer to the motherboard book to see where you made a mistake.
If you get no power at all, check to make sure you plugged in all the necessary power connectors. If you get power to fans but get nothing on the screen, you could have several problems. The CPU, RAM, or video card might not be connected to the motherboard properly. The only way to determine the problems is to test. Check the easy connections first (RAM and video) before removing and reseating the CPU.
Expansion Cards Installation
To successfully install an expansion card, you first need to make sure that your motherboard has the appropriate slot for that card and that it works with your operating system. Next you must provide the drivers for that operating system and finally you must verify that the card works correctly on the PC.
The previous procedure applies to all types of expansion cards, the most common being video, sound and network cards.
Here’s a basic procedure for installing an expansion card, such as a graphics card or sound card, into a desktop computer:
1. Preparation
Before you begin, turn off your computer and unplug the power cord. Also make sure you are working on a clean, static-free surface to avoid damaging components. If possible, use an antistatic wrist strap properly connected to the PC, as indicated in the “Work Safety, Professionalism and Tools” post.
If you don’t have a wrist strap, you can use the technical way to avoid ESD by touching the power supply or PC case (as also recommended in the mentioned post) after removing the expansion card from its antistatic bag. This places you, the card, and the PC at the same electrical potential and therefore minimizes the risk of ESD.
2. Identify the Expansion Slot
Locate the empty expansion slot on your computer’s motherboard where you plan to install the card. Common slots are PCI Express (PCIe) for graphics cards and PCI for other types of expansion cards.
3. Remove Cabinet Cover
If the expansion slot is covered by a metal plate on the computer case, remove it by unscrewing the screws securing it.
4. Prepare the Expansion Card
Remove the card from its packaging and be sure to handle it carefully to avoid damage. If there is a plastic protector on the connectors, remove it carefully.
5. Alignment
Carefully align the expansion card connectors with the expansion slot on the system board. Make sure they match correctly and the card is straight.
6. Facility
Carefully insert the card into the expansion slot. Apply even, constant pressure until the card is fully inserted into the slot.
7. Fixation
If the card has a metal bracket that attaches to the case, secure it by screwing in the provided screws. This will help keep the card in place and prevent it from moving.
8. Power Connection (if required)
Some expansion cards, such as high-end graphics cards, may require an additional direct power connection from the computer’s power supply. Be sure to connect any necessary power cables to the card.
9. Cabinet Closing
Replace the cabinet cover and secure it with the corresponding screws.
10. Connection of Peripherals
Connect any necessary cables or peripherals to the expansion card, such as monitor cables, audio cables, etc.
11. Power on and Test
