@Anthony_Mazio1- -- When I plug in my freshly built computer it will turn on for a quick second, then turn off
For some brands of computer, this is normal, e.g., my Lenovo desktop. This happens when the computer is connected to electrical power. It does a quick POST ("Power On Self Test"). If the POST successfully completes, the computer powers-off. If the POST "fails", then the computer starts "beeping".
then turn back on,
Most motherboards have an option to "after the end of a power-outage, automatically power-on".
This is good when you want your computer to be a "server" that will reboot after an power-outage.
Is your computer configured in this way?

Something is wrong -- the POST might be "failing". Do you get any "beeps", or flashing-lights on the lamps on the computer's case, or on the lamps on the keyboard, in some sort of pattern?
