Windows 10: Powering down PC resets BIOS

Hi guys, weird issue here and hoping someone has any ideas to why.

I typically remove power from my PC whenever I go out of town due to power outages that sometimes plague my area (yes, I have a UPS, still…). Down time here was 3 days.

Anyway, after restoring power and booting the PC there’s usually no issues. However, this last time, upon powering up I noticed the BIOS had reset to its default settings – XMP disabled (I always enable), splash screen enabled (always disable), fast startup disabled (usually enabled), as well as a few other areas.

I don't think this is a CMOS battery issue as both BIOS clock and date maintained the correct time and date.

Anyone see this before? BTW this is a Gigabyte Z390 Aorus Xtreme. See system specs. Also not overclocking.

:)

Bootloop after RAM upgrade. Reset BIOS?

The assumption is that the cause is the newly added RAM.
This may or may not be correct.
These are some trial and error steps:

1) Remove all RAM modules and re-seat one module.
Remove the power cable and hold down the power button for 30 seconds.
2) Power on

3) These are links for resetting the BIOS:
