Installing a Motherboard
In this video I will perform a demonstration of installing an MSI MAG X570S Tomahawk motherboard. I won’t be installing other components like the CPU and memory modules as I will leave them to another video.
Demonstration
It is not a bad idea to have a look at the manual before installation. Some motherboards may have additional jumpers, although on modern motherboards this is pretty rare. Once you have installed a few motherboards, unless it is a proprietary motherboard, you will notice the installation process is pretty similar.
Generally, when I look in the manual, I will first look at the motherboard diagram. This will give me an idea of where everything is. If you are trying to plug a connector into the motherboard and are having trouble finding it, have a look at this diagram.
The next part of the manual I will look at is the section on front panel connectors. As we will see in the demonstration, these connectors are what connects the computer up to the computer case. This includes power, reset, USB and audio.
Now, let’s have a look at how to install the motherboard.
Motherboards are vulnerable to electrostatic discharge, so you always want to take some anti-ESD precautions before installing the motherboard. In this case I have an anti-static mat. If you don’t have an anti-static mat, as a substitute you can always put the motherboard on the box the motherboard came in. Some anti-static protection is always better than none.
Since I have an anti-static mat, I won’t need the box. On the corner of the anti-static mat are two grounding points. On one of these grounding points I will connect a ground cable with an alligator clip. I will use this later to ground the computer case.
I will next put on an anti-static wrist strap and connect the other end to the other ground point. This will provide a connection between me and the anti-static mat.
I will next place the computer case that I am going to use on the anti-static mat. To install the motherboard, I need to remove the side panel. For this particular computer case, there are two screws at the rear of the computer case that need to be removed.
Once the screws are removed, I next need to slide the panel and lift it upwards to remove it. Your computer case may be different. Some cases do not have screws but instead have clips that hold the panel in place. Other computer cases may have a lot more screws to hold the panel in place.
Now that the side panel is off, I can connect my alligator clip to a metal part inside the computer case. There is a problem - you will notice that as I look around the computer case everything is painted. In the old days there was always some metal edge that you could connect your ground cable to, but nowadays many computer cases don’t have any metal points to connect your cable to. The only possible points will be covered by the motherboard when I install it.
To understand how we are going to fix the problem, I will perform a quick experiment. You will notice with this multimeter, that when I connect the two terminals together, I get a reading on the LCD screen. This setting on the multimeter is designed to test for a closed circuit. That is a circuit that lets electricity through.
If I now connect the terminals to each side of the screw that I removed from the case, you will notice that I get a reading on the multimeter. This indicates that electricity can travel through the screw. Thus, if electricity can, so can static electricity. The learning outcome here is, that even though your computer case may be painted, electricity can still potentially travel through it.
Different parts of the computer case may be painted with different thicknesses of paint. You will notice that when I put terminals on different sides of the painted computer case no connection is made. Thus, painted computer cases don’t make a good choice for ground cables. Generally, the paint is too thick for a connection to be made.
