[SOLVED] ASRock B450M-HDV Won't Boot

[jbrownracing12]

ASRock B450M-hdv won't boot on a new build. All the fans come on and the SSD LED power is lit, but no boot display. I have tried to reset the CMOS, disconnected and reseated all the cables, swapped the RAM around and made sure they were completely seated, and checked for any bent pins on the CPU.
I have a Ryzen 3 2200G CPU, Ripjaw 2X8 DDR4-2800, and Crucial MX500 m.2 SSD.

This is my first build with m.2 and with no GPU but I'm kind of at a loss what to try next.

Remove m2, take motherboard out of case only have cpu/1 stick of ram in correct slot per motherboard manual instructions and see if it'll boot. We can work forward from.there if that works.

Ok the MB is removed from the case, single RAM in the A1 spot. And m.2 removed. Powers on but no display still.

Well that's disappointing... Seems it's likely the board is bad but hard to do any trouble shooting unless you have other PC's around for parts to scavenge. Do you have some?

I do but it's ddr3 memory and an Intel board. Don't think anything is compatible. This is my 4th build and I have yet to RMA something. How do I tell if it's the MB or CPU that's bad?

My money would be motherboard as I've never gotten a bad cpu in 75+ builds.

Second guess would be power supply.. which is the one thing you could steal from your other build if you wanted to.
