POST is one of the best tools available when a system will not boot. Normally through the use of either display LEDs in more modern systems, or traditionally through audio tones, these specific codes can tell you what the system doesn’t like about its current setup. Because of how rare these events can be, unless you are on a tech bench day in and day out, reference materials such as the Motherboard manual and your search engine of choice can be tremendous assets. Just remember to make sure that everything is seated correctly, you have at least the minimum required components to boot, and most importantly that you have all of your connections on the correct pins.
