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?
