Change and how to install new motherboard?: step by step instructions
Whether you want to change a defective main board or want to install a new one, you are at the right place here. In these instructions, we explain exactly what is important if you want to replace your mainboard.
If you follow these installation instructions for the motherboard as part of our complete PC assembly instructions, then you should already have your CPU, CPU cooler, and RAM installed on your motherboard because that is much more practical and makes installing your main board easier.
So let’s change your motherboard now. The only thing you need is a Phillips screwdriver, spacer installation tool, an anti-static wrist strap (optional), and the main board manual.
Change or how to install new motherboard?: You should pay attention to this before
how to install a new motherboard?, you should consider a few important things.
Get a model with the same chip set.
Replace only with a main board with the same CPU socket (otherwise, you could get compatibility problems
It is best to choose one with the same form factor (size, length) so that there are no problems with space.
Checks whether your old motherboard has all the connection options you want. If not, you can think about getting an equivalent model with more ports.
For this, it is important to know which main board you have. As soon as you know that, you can choose an appropriate replacement model.
Remove the old main board
If you have to replace your mainboard, you have to remove your old main board first. If you want to install a new main board, then skip this point.
Before you start to change your main board: Ground yourself. This ensures that you discharge all electrostatic charges. You can do this by touching a faucet or radiator to dissipate static electricity. It is best to wear an anti static wrist strap to prevent electrostatic damage.
Removing a motherboard is pretty easy. Just follow the steps below:
It is best to take a few photos BEFORE dismantling to make installation and wiring easier later.
Make sure you’ve put your case on its side, then you’ll have better access to all parts.
Remove the rear screws on the housing of the graphics card. Loosen the clip on the GPU’s PCIe slot and carefully pull the graphics card out of its port.
Unplugs all cables from the motherboard.
Loosen all screws from the spacers.
Carefully pull the main board out of the case.
Changing and installing the Motherboard: this is how it works step by step
To install a mainboard, we have to reverse the steps described above – but this will take longer. The installation of the CPU or the cooler is not covered here, as you should do this before installing the main board.
1. Unpack the new motherboard
As soon as you open your motherboard’s packaging, you will see a lot of cables, a driver CD, a metal cover plate with cut-out holes, and a manual. Take these components out and set them aside as you will need them later.
The motherboard itself is in an anti-static bag and rests on an anti-static foam cushion. Pull the mainboard out of the bag, but leave it on the foam for the time being. Place the motherboard and foam on the anti-static bag and remove the metal cover plate (also called the I / O panel).
2. Insert the I / O cover
Next, we use the I / O cover that came with your motherboard. The socket provided for this is located on the upper rear of the case and protects themotherboard connections for the monitor, USB, and other peripheral devices. Some more expensive motherboard already have a backplate / IO shield pre-installed. If that’s the case with you, skip to the next step.
In most cases, a standard cover is installed in the case, which must be removed and replaced with the cover supplied with the motherboard. How to use the cover correctly:
Find an opening on the back of the case that is the same size as the bezel.
Now place the cover on the recess from the inside of your housing (it only makes sense in one direction – the audio connections usually point downwards).
Put pressure on all four corners of the bezel to secure it in the case. The bezel should click into place properly.
Make sure you are installing the panel in the right direction. Compare it to the actual layout of the connectors on the motherboard to make sure everything fits.
To ensure that the back plate is properly and securely in place, press it lightly on the outside as well.
3. Checks where the motherboard should be installed
Then you have to check where your motherboard should be screwed into the case. Because depending on how big your main board is (ITX, mATX, ATX, EATX), you will align it with different screw holes.
In other words, map all pilot holes on your motherboard to the holes in your case – the spacers must be installed there. Remember to hold the main board by the edges and ground yourself in front of it.
To do this, take the motherboard from the foam pad and carefully slide it into the case. Ensures that the rear connectors are properly seated against the IO bezel. Now make a note of the screw holes on which your main board rests and put it back on the foam.
With this step you know which holes you have to screw the spacers into in the next step.
You will find a corresponding legend that shows you where your main board and the spacers should be placed with some case models. Spacers hold the motherboard above the case. This prevents a short circuit and also helps with cooling.
4. Place spacers
With some housings, the spacers are already pre-installed. With others, you have to screw them all in yourself. Please note: With different main board sizes, the spacers must be installed in different holes.
Larger motherboards require more spacers than smaller ones. For example, the installation of a microATX main board usually requires six spacers, while standard ATX mainboards usually require nine of them.
To place and tighten your spacers, you will need to use a small attachment for your screwdriver (or a special tool for it). This should be included with your case, but sometimes it is also included with the motherboard.
To do this, place the attachment on the top of each spacer to screw them in individually with your screwdriver. This assumes that your spacers are made of metal. If you have older plastic standoffs instead, you may be able to push them in with your hands like pens.
In general, you should use as many spacers as there are mounting holes in the motherboard. This ensures that your motherboard is properly secured in the case. But sometimes, a motherboard has mounting holes that do not match the standoff holes on your case. If this is the case, you don’t need to place any spacers there. As long as the board is well secured and can be installed without direct contact with the housing.
If you want to change your main board, the spacers are extremely important
5. Insert the main board into the housing and install it
Now you take your main board and carefully lower it onto the spacers so that the rear connections are flush with the previously installed rear panel. Also, it makes sure that each spacer fits into the holes on the board. To get everything right, you may need to press the motherboard against the back plate carefully.
Look through the back of the case at the IO bezel to ensure all connectors are properly aligned. Once the board is correctly positioned, grab the motherboard screws and screw them in. Proceed as follows:
Start with the corners and hold the motherboard in place so that the screw holes line up with the spacers.
Do not apply too much pressure when screwing in the screws so as not to damage anything. Nevertheless, the screws should be hand-tightened
Once the corners are ready, you can turn the screws into the other holes.
How you turn the screws, in the end, is up to you. Often you don’t have to use all of them so that the motherboard sits firmly in the case. Over time you will get a good feeling about it. You better play it safe with your first construction.
6. Connect the ATX main power plug
As soon as the main board is screwed on, you are almost done! First of all: Regarding the cabling of the power supply and a detailed explanation of all main board connections, have a look at the following articles (if you need more information – we are only touching the basics here):
Main board connections explained
PC power supply connections and cabling explained
Next, we need to connect it to your power supply. First, you have to find the ATX connector of your power supply. This is the largest cable hanging from the power supply (or in the cable pocket if you have a modular power supply) and has a 24-pin connector.
The cable can only be plugged into your main board in one way. You will find that some of the pins are completely square and not rounded at the end. So use this to make sure the connector is properly oriented.
However, since older motherboards only need a 20-pin connector, a four-pin connector can usually be removed. However, newer models all use the 24 pins.
7. Connect CPU power
Then we take care of the juice for the CPU. Modern main boards also have a secondary power connection, usually located at the top left near the CPU socket. Most models will have a single four-pin connector, but some will require eight-pin connectors. So check what your power supply has, as you may have to buy an adapter.
Similar to the 24-pin plug, the eight-pin plug on power supplies can be divided into two parts. If your main board only has a four-pin connector, you have to split the connector in half and connect only one of them to the motherboard.
8. Connect the front panel
To turn on your computer with the front power button or to see when the hard drive is being accessed, you need to power the buttons and indicators on the front. To do this, you take the cable with the many small connectors and connect them to the corresponding pins on the lower edge of the main board. You will find the following connectors:
Hard drive LED
Look in the manual to find out how to connect your front panel connectors – this is different for every main board
This part is the first part of changing the motherboard. Definitely consult your manual if you are replacing your main board for the first time.
9. Attach USB headers, fans, hard drives
Then you connect all the front USB ports to the corresponding ports on the motherboard. These are typically labeled. Makes sure the correct connectors are on the correct pins.
You also connect all the case and CPU fans to the corresponding pins on the main board. Usually, there are several places to connect case fans and a two-pin connector near the CPU for the CPU fan.
As soon as everything is securely and cleanly connected, you can still connect your hard drives (HDD, SATA SSDs) and drives. The same applies here: Make sure that you connect your hard disks and optical drives to the correct SATA ports on the motherboard.
If in doubt, you should consult your manual for this, especially since it looks slightly different onall motherboards.
Congratulations, you succeeded in exchanging (or installing) your mainboard! It wasn’t that wild, was it? Of course, you still have to supply your graphics card with power and ensure that all cables are neatly laid. But your main board is definitely ready to use.
