New Processor; Just Rebooting

I decided it was time to get off of Windows 7 and do what it takes to get to Windows 11. First, the original setup:

X370 Killer SLI/ac on BIOS P5.30
Ryzen 7 1700
2 ea Gskill Flare X 2400 sticks of RAM
Samsung 960 EVO NVME SSD

I've had this setup running since 2017 with no problems.

The first thing I did was clone my SSD to a hard drive, and got that to boot successfully. Then I flashed the BIOS to P5.40, then P6.00, then P7.00, then P7.30. All of this went uneventfully. Then, I upgraded the OS to Windows 10, initially 1809, then upgraded eventually to 22H2. This was a bit tedious, but again uneventful. Next I used mbr2gpt.exe to convert my disk to GPT, then turned off CSM in the BIOS, and ensured fTPM was enabled. This was successful also. The Windows PC Health checker for Windows 11 showed that the computer met all requirements except the CPU. According to Asrock, a BIOS of P7.10 or later supported a 5700X, and I had BIOS 7.30 on here. So I removed the Ryzen 7 1700 and put in its place a newly purchased Ryzen 7 5700x. On power up, all it does is reboot. The Light on the motherboard comes on, the heatsink fan spins, the drive gets hit, then the motherboard light goes out and the fan spins down. I let it sit for over a half hour, no change. I removed on memory module, from B2 (leaving the other on in A2), and tried this. Same behavior. I waited 10 minutes. I then put the 1700 CPU back in, and it boots up just as it did before.

Is this a bad CPU? Should I try BIOS 10.08 or 10.31?

Hello!

I am glad that the BIOS update solved the issue.

Now, I'd suggest you do a clean install of Windows 11 v24H2, instead of an upgrade from Windows 10 to Windows 11.
It's safer this way!

Please create a bootable USB flash drive, using the free app Rufus!
There are some options at the creation of the USB that you can check, so they'll be disabled, like:
Copilot, drive encryption, the check for TPM 2.0, etc.

One more thing:
If you'll ever update the BIOS again, it is recommended before doing it, to turn off the fTPM in the BIOS menu, otherwise you could end up with unexpected errors!

I hope this helps...
