Question Pc bios incorrect config/refusal to boot/constant restarting

[rozh001]

So yesterday i bought more ram for my pc and upgraded it, when trying to bootup my psu died so i changed it out and had no further issues. Today when i booted up my pc the computer booted into bios and said i had an incorrect configuration. After pressing f7 to get default settings it either goes into a restart loop or goes into go GRUB GNU but cannot go into anything else. I tried with all different ram sticks in different slots, had in 2, 1 or all 4 but the exact same issue persists. I tried taking out the cmos to reset all settings but that didn't help either. I disconnected all my storage besides my nvme ssd which is my main one and tried booting into it, i have a ubuntu option which prompts me into GRUB GNU and then i have the normal option which flicks into a black screen and then takes me back to the f12 boot screen. Typing exit in GRUN yields the same result. Any help?

I7-9700k
Z390 gigabyte
32 gigs ram of 3200 mhz, 2 different brands kingston and hyperex which both does have a FURY collab
2080 ti
Evga 650 g2

It died yesterday right after inserting the new ram sticks, it started for a split second and then turned off again. Changed out to a almost identical evga psu and worked fine until this morning. I have disconnected all storage devices besides a ssd with an old Windows setup on it but whenever i try to boot into it i get into a empty console prompt for a few seconds before going back into the bios boot menu. This happened to my main nvme ssd too in the exact same way

I have solved my problem for now. I still have no clue what caused it but i solved it by literally rebuilding my pc and checking every single slot. I don't feel confident on this being a solution that'll last though
