Computer only starts (and posts) once after CMOS reset

Go to solution Solved by Drummyralf,

Welp, I reinstalled windows and downgraded my BIOS. Seemed to fix the problem for now.

Setup:

Ryzen 5 1600

Asrock Radeon 6700 XT

HyperX Fury 2400 mhz DDR4 (2x 8GB) (edit: in slot A2 and B2)

Asus Rog Strix B350F motherboard

Samsung NVMe M.2 ssd 980 1 TB (windows drive)

Samsung Evo 860  250 GB

WD Blue 1 TB

Windows 10 64 bit

(edit)Seasonic M12 II Bronze 620 Evo edition

 

I switched GPU about a month ago. The rest of the build has been working for years.

Updated BIOS to 6203 a month ago.

PC worked great for about a month.

 

Short description:

I can only post (and launch Windows) after I reset CMOS and do a "discard and exit" in my BIOS. If I Save and Exit, the PC does not post.

After a CMOS reset, I can also boot by overriding boot by the drive that has Windows on it.

 

If I power off windows, it doesn't post. Need to reset CMOS again.
If I don't reset CMOS, my motherboard gives a white LED indicator (indicating GPU fault) but it also does this with my old GPU installed.

 

Things I tried:

-Using only 1 stick of ram (tried both)

-Replacing CMOS battery with a quality new one (says 3.2v on multimeter, old one says that as well)

-Switching GPU to different PCIE slot

-Switching back to old GPU

 

The last thing I did last night was installing Steelseries GG suite for my new Rival 3 Mouse. This morning, it didn't post.

I uninstalled GG driver (by CMOS reset, discard and exit) but that didn't fix the issue.

Also, currently only have a generic keyboard conneted for all the testing, no other USB devices.

 

Any help would be greatly appreciated. Thank you!
