Question Weird issue with AM5, can't boot after first time?

[paisa]

Hello there. I built a PC with an Asus Prime B650 Plus, Ryzen 7700x, 32GB Corsair @4800mhz and an AMD 6800XT.

I updated the motherboard BIOS version from 0823 to 1811 and I can't get the PC to boot after the first time. The first time the PC boots, it goes into memory training (gets restarted 2 or 3 times) and then it boots into Windows just fine.

However, when I restart the PC, it simply won't boot. No error beeps, no restarts, nothing. It won't post or let me go into BIOS, keyboard doesn't turn on, nothing at all. Just black screen.

The only thing that works at that point is removing the motherboard battery for a couple minutes and booting again. Then, the memory training happens again, it boots into Windows fine, but after the PC is rebooted the problem arises again.

I figured AM5 would be polished by now but it seems it's not the case.. Any suggestions?

Quick note: before updating the BIOS it suggested to revert back to default settings (had not changed anything from default but anyways), this is the only change that was applied:

Bios shows correctly updated version:

Do you have RAID enabled? If so, why?

Is this a fresh install of Windows with this hardware, or one recycled from a previous config?

Change TPM to fTPM, unless you installed a separate TPM device.

No RAID. Fresh install.

I read some post with not exactly the same problem but suggestion to change the Restore Memory Context from Auto to Enabled and that seemed to fix the error. It was hidden in one of the RAM settings dropdowns.

If someone could explain why that fixed it, or now understand what could be causing the issue, I'd be glad to understand it as well.
