New build POST 5 beeps

This is the conclusion we've come to after a lot of studying of manuals and spec sheets!

Unfortunately, despite having been a radio communications and broadcast transmission engineer for the past 25years, working down to component level repair, its been a long time since i last built a PC (last was a Pentium II), so im not fully up on the current tech, and misread the mobo blurb where it says onboard graphics with A-series APU! I'd never even heard of an APU until today (to me an APU is part of an aircraft!), and had no idea there was an AMD A-series of processors!

Although the ASRock spec for this mobo says 5 beeps is a CPU error, the beep info for the UEFI chip says 5 beeps is missing VGA. Both make sense - if the BIOS expects a GPU and one isnt found installed, nor a suitable CPU with one, then I could see it returning a CPU error!

Although I cant be 100% certain that its not a fault, ive installed enough ICs of every type over the years to be fairly confident that all the pins are good, especially in light of the above revelation.

I'll borrow a couple of graphics cards out of our system spares at work and see if we get further! If that sorts it, then I suppose i'll just have to order a card

I'll report back

I don't see a GPU in your specs.

It's a common mistake people make when assuming Ryzen 5 1600 has a built-in GPU (aka iGPU).

With this CPU you do NEED a dedicated GPU.

Otherwise, your BIOS version should be compatible with the CPU.
