Hello good people. Issue is as it says in the topic. I am at my wits end on this one, so any help that you can shoot my way will be met with eternal gratitude!

The bios chip has 4.60 printed on it and the box has a neat little 'Ryzen 2000 series ready' sticker on it.

The CPU heatsink fan spins up, the power LED turns on, the HDD is spinning and there is power to the USB ports.

I have built the system with the parts below:

FSP Raider II Edition 550W 80PLUS Silver Power Supply

ASRock AB350 Pro4 AM4 ATX Desktop Motherboard

Kingston 8GB Kit (2x4GB) DDR4 HyperX Fury Black C15 2666MHz (placed in A2 / B2 positions)

Kingston SSDNow UV400 240GB 2.5" SSD

AMD Ryzen 5 2400G 3.6Ghz 6MB AM4 APU Retail Box - With Fan

Things I have tried:

RAM - Removing / replacing / placing into different configurations.

CPU - taking off the heat sink and checking it is seated happily (it is).

Power - ensuring that the 8 pin and 20+4 pin connectors are connected (they are).

Monitor - checking that it is working on another machine (it is). Trying a different monitor (also doesn't work).

Drinking coffee / meditating - still frustrated.

Thanks for any and all help!

Do you install a beep on MB? If yes, I guess no beeps mean MB issue.

alxnilsen, your power supply is marginal at best, but I think you should be able to boot.  The ASRock MB does not have a speaker, please buy one (buck or two) and then you can post the beep code.  creatie said as much.  Maybe more coffee/meditation.  Try one memory stick in various slots, if you have not.  Good luck and enjoy, John.

Your motherboard has the correct minimum BIOS for your Ryzen 2400g which is P4.60.

According to ASRock Support, your Memory IS NOT LISTED on its QVL list for the Raven Ridge APU: ASRock > AB350 Pro4

DDR4	HyperX	2666	2666	8GB	HX426C16FB2K4/32	Micron A-die	SS	2/4
DDR4	HyperX	2666	2666	8GB	HX426C13PB3K4/32	Hynix A-die	SS	2
DDR4	HyperX	2666	2666	8GB	HX426C13PB3K4/32	Hynix M the	SS	2
DDR4	HyperX	2666	2666	16GB	HX426C13PB3K4/64	Hynix A-die	DS	2

According to your link your Kingston RAM MEMORY Number is "HX426C15FBK2/8"  This may be the reason you are having problems. The RAM MEMORY installed may not be compatible with the Ryzen APU.

You also have a new BIOS Update for your Motherboard: ASRock > AB350 Pro4
