Gigabyte X370 K7 Bios code AA With Random Reboots

Getting Random Reboots with X370 K7, Normal operation code is 30 or 40 not AA, any thoughts.
Tried another GFX card and power supply also unplugged the power button for now just incase thats playing up and reset the Bios and tried the backup bios as well , codes on page 40 say AA is reserved.

I'm assuming this is an existing (not a new build)?

Did anything at all change with the PC or how you used it prior to this happening?

Yes existing build with no recent changes,it just started playing up over the last few days and it's very random. I do have a fresh motherboard to try an Asrock AB350M but I've never changed a Motherboard on an existing windows build, I would imagine thats not going to go well.

Strip everything down to the bare basics and see if anything pops up and revert any overclocks, including turning off XMP. A quick google a few others had AA and found it was a faulty GPU, but you already tried another so it could be something else.

I had a faulty X370 K7 board too but think I was getting a different error code, had to RMA it in the end.

EDIT: Just checked, it was showing 54, so different from yours.

It seems happy for now, I had 1 restart while it was on the test bench after I had pulled it apart (hence thinking still broke) to clean and change the power supply and reset the bios, also tried bios B(Old Version)which gave the same AA code. I then removed the power button wires and put it back together and put it to use over the weekend with no problems reported, so fingers crossed. New power button arrives today. I also benched another pc for about 4 hours with the suspect power supply which of course seems to work just fine, pc's eh!

Checking that code from the Manual above on page 42 shows a memory problem "50~55 Memory initialization error occurs".

We have 2 X370 builds Identical to each with 8pack DDR4 3200 Samsung Ram which in the main have been solid. But they both have different bios versions, the AA code might be normal I just don't recall seeing it. The other PC when booted shows 30.
