Update your post to include full system hardware specs and OS information.

Disk drives: make, model, capacity, how full?

PSU: make, model, wattage, age, condition? Heavy past use for gaming, video editing, or even bit-mining?

Will the PC boot into Safe Mode?

Try a new CMOS battery.

This motherboard?

FF code is Power on and first initialize CPU (see physically numbered Page 2-21

Did you physically insert the first RAM module/stick in DIMM1 first.

Note: I also found the motherboard manual on MSI's website. Downloadable as a Zip file.
