I've seen a lot of questions already from people whose new PC won't post or output a signal however I haven't seen a post that's identical to mine. I have a Ryzen 5 5600g, b450m ds3h v2 mobo, 2 X 8GB ddr4 corsair ram and an EVGA power supply. i haven't been able to get my new PC to post for about a week now. My fans spin and however no video output nor power to my peripherals. I've tried basically everything apart from replacing my CPU .

I've bought another motherboard (the old one was b450m DS3H V1), used different monitors and cables, using integrated graphics and a separate graphics card, used my old power supply from my old build, installed both 1 and 2 sticks of ddr4 ram in every dimm slot. plugged in and taken out the cables to double-check they are all connected properly. changed and replaced the CMOS battery and bought a bios speaker for my motherboard in order to hear beeps so I might be able to diagnose something however I'm unable to hear any beeps when starting up.

the only thing I haven't tried is using a new CPU which is seeming like that's the problem. I've physically checked the CPU and to me, it looks perfect with all uniform gold pins which is why I'm hesitant to replace it. I've seen some comments saying that the CPU is not compatible with the mobo without an update but I've checked on pcpartpicker and other sites which all say it's compatible. I'm just wondering would a dead CPU cause all the symptoms of no beeping and no video output but spinning fans which doesn't turn itself off and no power to the peripherals?

Any feedback welcome :)

The first question is: did this combination of parts ever work? A history of the problem would tell us a lot.

If you never had the 5600G running, what BIOS did you upgrade your motherboards to? Neither of these motherboards will run a 5600G without recent BIOS updates.

Both motherboards require at least the F61 BIOS to work with this APU and was released on 7/22 of this year.

I haven't touched the bios in anyway . if this specific motherboard doesn't support 5600g CPU out of the box without a bios update do you recommend any motherboards that do?
You will generally need a BIOS update to run out of the box. Because the CPU is a very new release and there's no accompanying line of motherboards, you'd need one that was manufactured very recently and that's not something you can always tell when ordering something. Something like a MSI Mag B550M Bazooka in the budget category would be appropriate, but it would require you to use the BIOS Flashback feature to update the BIOS. MSI includes that feature on most of their motherboards except for the very cheapest ones. Other alternatives include updating the BIOS with a compatible CPU or bringing the motherboard to a local shop and have them do it.
