New computer doesn't want to post

[Hyra]

I've spent my morning helping a friend build a new computer for himself, and everything was going well until the moment of truth. At first, the computer refused to even turn on. After a bit of screwing around, we got the motherboard LED to come on. After we moved the RAM stick from one slot to the other, peculiarly, the computer turned on, but still failed to post. I'm at a loss, we've tried to reseat everything but the CPU, used different displays, and so on. I don't know how to troubleshoot this board because it doesn't even display post codes.

AMD A8-9600

Asus Prime A320M-K
Patriot Signature 8GB
Cooler Master Elite V3 500W

Is the case cables in the correct spots? Where input plugged in?

Everything has been checked over multiple times, everything is plugged in and it just doesn't want to work, I'm guessing it's either a CPU or a RAM issue

There are multiple ways troubleshooting data is displayed, there are lights, beeps or digital codes.  The motherboard manual should say what it does and how it works.  It is an a series motherboard.  They do go cheap on those as hard as they can.  The oldest cheapest system is the beep code which requires a speaker be attached.

My friend tells me that the motherboard didn't come with a speaker, and he's not the type to have those laying around. Is there an LED or something on that board that can be used instead?

The manual will say.
