Ryzen 5 2400g asrock AB350M 5 short beeps

[daveasp81]

Hi all I purchased new an asrock AB350M motherboard and Ryzen 5 2400G APU to upgrade my aging system.
I installed everything into my old case using my existing psu and gpu GTX 660, however when I first turned it on all I got was 5 short beeps from the bios. I've tried to reseat the CPU, used only 1 stick of ram, tried different ram slots, removed the gpu and I'm at my wits end. I know the 5 beeps means bad CPU but I'm hoping I won't need to rma the CPU as I know that can take time.
Can anyone suggest anything else I can try to get it to work?
Thanks in advance.

You need to update the bios on the board before you'll be able to use a 2nd gen ryzen processor. You can either get a shop to do it for you (for a fee I imagine), borrow a compatible cpu from someone or apply for a ryzen boot kit from amd.

The box said it has had the bios flashed already, could it be that it missed the update somehow?

Well it very well could be a different issue all together but the fact you are using a 2nd gen cpu, a 1st gen mobo and its saying its a cpu error then I'd wager someone screwed the pooch and didn't update the bios as intended.
