How to install a Motherboard | Gigabyte GA-H55M-UD2H

Before installing any components you must discharge yourself from any static energy. This can be done by using an anti static wrist band. Or alternatively by touching a metal surface such as the metallic area of the case.
Before we start mounting the motherboard we need to fit the ATX back plate. These back plates come supplied with the motherboard. Back plates are normally labeled and colour coded. Make sure you are holding the back plate the right way up, and face the labeled side towards the back of the case. Using your fingers push the plate so that it snaps into position. It can take some force to get all the corners into place. Once the back plate sits correctly into place, it should look something like the image below. As you can see, the plate has cut out so the motherboard’s ports fit perfectly in to position.

The gold colored screws below are called standoff screws which are used for mounting the motherboard. Your case may have many holes for the standoff screws. Which holes should you use ? The easiest way to find out which holes to use is to place your motherboard on top of the holes. See which holes on the motherboard line up with the holes on the case. Mark the holes using a pencil. Those are the ones you’ll install the standoffs into.

Do not use extra standoff that does not match the motherboard as it will cause a short circuit. Start placing the standoff’s using your finger and tighten them using a plier.

This is a Gigabyte H55M UD2H motherboard. It has an Intel 1156 socket supporting i3, i5, and i7 processors. Place the motherboard on top of the standoff screws making sure that the ports slide into the back plate first. Use the supplied screws that goes into the standoff’s to secure the motherboard. Place the screws into each hole and tighten it using a screw driver.
