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 UV500 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!

Got some bad news for you --> that sticker on the box is meaningless and worse so is the sticker on the BIOS chip. I got a second X370 Pro4 recently and despite the sticker on the box the chip had 4.50 printed on it and that's exactly what was installed. My first X370 Pro4 board had the sticker and 4.60 printed on the chip and that's what was installed...

That all being said borrow a GPU from a friend or get a cheap one on Craigslist and see if you have video with such. If so and the BIOS turns out to not be 4.60 flash up to 4.90. If it's older than 3.40 be sure to flash to that before going up to 4.90.
