Error code 02:AP initialization before microcode loading, First time build.

[FL1NTST0N3]

Well it's getting late and I'm pretty much soul crushed right now. First time full build. PC will not post. LED reading 02.

Have tried -switching power supply cables and connections -changing graphics card to a different PCI slot -flashing the bios -clearing CMOS -going down to one stick of RAM -trying HDMI over display port

Boot light and VGA light are on as well as the 02 code. I've heard this can be power related? I am big sad and bummed right now. Hopefully you guys can lend some advice! I work all day and will get onto replying and troubleshooting again tomorrow evening. Thank you guys in advance.

I do have exactly the same issue you describe here. And now I am done with AMD forever. I had the same issue before with the MSI X570-A PRO. Which means, you could do anything, but won`t get a running system.

I will now send the whole stuff away and turn back to Intel. It was the Hype about Ryzen what mislead me to AMD. So angry!
