After messing with the BIOS settings, the computer won't boot ...

Dear PCMR community,

I hope our collected knowledge can help me fix this problem that is driving me crazy currently.

Hardware:

• Asus ROG Strix B550i

• AMD Ryzen 5600x watercooled with Asetek 645lt

• Gigabyte GeForce RTX 3060 Eagle OC LHR 12GB

• Corsair Vengeance LPX 32GB (2 x 16GB) DDR4 3600Mhz

• Corsair SF600

• DANCase A4 SFX v4.1

• Windows 11 Pro 64bit

• No overclocking (Only XMP/DOCP)

I built an ITX setup in January this year and for some reason, my BIOS keeps resetting after every shutdown (not only on A/C loss!). You could think, that this is quite easy - the CMOS battery must be dead. But that does not seem to be the case as the time and date is always correct, even after unplugging the PC from power for several hours. The CMOS battery seems to be fine.

Upon powering the PC up, it shows the message "Please enter setup to recover bios settings", indicating that some test failed. In the bios, all settings are back to default and I have to adjust the settings manually or load from a profile, which I created earlier (the profile also seems to survive shutdowns/power losses). This is quite annoying as I use the PC while travelling as a mobile gaming setup and it's impractical to reconfigure the BIOS on every boot. As long as the PC is running, I face no issues at all, it's perfect. But when shutting it down for a few minutes, the problems occur (reboots and shutdown and instant boot are no problem).

Things I already tried:

• Resetting BIOS by flashing the latest BIOS

• Updating BIOS to latest version

• Reinstalling Windows with all drivers from ASUS website

• Running full memtestx86 (all four tests pass 100% with no errors)

• Running Heavyload 100% sustained CPU+GPU+RAM+SSD load for 60 minutes, temps never higher than 75 °C, no errors

• Checking CMOS battery status in HWINFO

• Turning XMP/DOCP on and off

• Using BIOS with default settings

I had an Asrock x570 TB3/iTX before the Asus board, which faced similar issues (but that seemed to be intentional, as described in many Reddit and forum threads) so I switched to the Asus board. On the Asrock one, the BIOS also lost track of the time, indicating that it is a different issue.

I am unsure how to fix this or proceed now. Has anyone else faced similar issues? I am thinking that the CPU might be broken, but currently I am not desperate enough to buy another CPU just for debugging reasons. Taking my ITX build apart is always a lot of work and I just want the system to work.

Best regards and thanks to all of you for your efforts!

Maybe I’m doing it wrong, but it seems like the CMOS jumper on my B550i does jack shit. Tearing this thing down to disconnect the battery is the biggest PITA. Is there something I’m doing wrong?

Power off, screwdriver to jump the two pins. Nothing.

Trying to play with RAM timings, but having to do this every time it won’t post is killing me.
