Hi,

Your old bios does not recognize the new CPU, hence can't boot into UEFI.

You must use a Zen2 generation CPU or older to boot into the old bios, then update to bios version 7.00(BRIDGE), next remove the old cpu and insert the new cpu, finally update bios again to latest, probably 7.1 or whatever.]]> Wed, 16 Nov 2022 16:31:26 +0000 https://forum.asrock.com/forum_posts.asp?TID=25092&PID=101968&title=asrock-x570-phantom-4-will-not-post#101968 https://forum.asrock.com/forum_posts.asp?TID=25092&PID=101963&title=asrock-x570-phantom-4-will-not-post#101963 Author: Fencerrick

I built my computer 2 1/2 years ago
ASRock x570 Phantom 4 Gaming Motherboard
AMD Ryzen 5 3600 CPU
Noctua NH-U12S Cooler
Gigabyte GEFORCE RTX 2070 Super GPU
EVGA 750 PSU
TForce 16 GB DDR4 x2 (i.e. total 32 GB)

It ran well for the last 2 1/2 years

It would not start the other day. It did not even post and did not restart. I could not enter the UEFI. There was one LED post light lit. It was the boot light. I checked some forums and this had happened to others. The ultimate solution was to replace the CPU.

I purchased a new Ryzen 5 5600 CPU. I downloaded and have the bios update.

I have installed the new chip and tried restarting preparing to update UEFI. The CPU and DRam LEDS come on and stay on. After about 15 seconds it powers off and restarts. I am spamming the F2 or Del key as I power on.

I have:
removed and reseated the CPU
removed and reseated the GPU
removed and reseated the DRam
removed the CMOS battery and held the start button for 15 seconds while unplugged and reseated the CMOS battery

I do not know what to try next.

Any suggestions?

Thanks in advance
