CPU upgrade Ryzen 7 5700x3d won't boot

[aj1soad]

I've got a asrock x370 K4 mobo with Ryzen 1600. I've just bought a 5700x3d and the pc won't boot.
Ive recently updated my bios as well as it was only on version 3.5 where the current beta version is 10.31. Before purchasing the new CPU I contacted asrock and they confirmed it was compatible and advised me that I'd get a ftpm prompt on first boot and to press Y but that never happened.
I've set everything to default in the bios and enabled ftpm and still no luck. Ive also tried reflashing the bios with some of the old updates. Should I carry on doing this so all of the old updates are added ? Anything else I need to do ? Thanks

I would disable secure boot and fTPM prior to installing a new CPU.

I think ASRock used to have special instructions for this, but if I click the link on their website it directs to a page that doesn't exist

You're definitely not using the display ports on the motherboard, right? Neither CPU has any graphics.

What happens exactly? A black screen with all the fans running? Did you clear the CMOS?

Did you update the bios to 7.00 before you upgraded to 10.3?

Gigabyte (definitely) and msi (possibly) had a specific set of steps you had to go through when updating bios to support newer chips. Might be worth checking your motherboards website in case they have the same process.

asrock does as well
7.00 first before anything newer

Ftpm has to be disabled in order to update the bios.
Definitely using the display port on the GPU. When I power the pc on all the fans come on but usually on bootup you can see some number on the led on the mobo but I don't get anything. After a few seconds it will just reboot and does the same thing again.
Yes I've also tired clearing CMOS and taking the battery out.
Boots up fine with the old CPU though

Have you checked you followed the correct bios update steps? If the original cpu is working and the new one ain’t either the new one is doa (rare but possible) or you’ve not followed the correct steps

it sounds like you didn't follow the steps to upgrade bios gradually....

 

[something daft already!!]

Have you reset the BIOS to default? Maybe clear BIOS via the pin shorting on the mobo.

1. Disconnect the system's power cable
2. Remove the CMOS battery
3. Press the power button to drain any residual energy
4. Use a paperclip or other metal object to short the two points on the CLRMOS pad for at least five seconds
5. Power on the system and check it.
