BIOS splash screen + GRUB menu not showing

Hello, I was booting up my PC in the morning and I've noticed my BIOS splash screen and GRUB menu not showing. I pressed both delete key and F12 to test it out and it didn't work as my keyboard started freezing. I have to wait for GRUB to count down until the login screen pops up.

I have no idea what is going on with my computer. I have fast boot disabled by default, and I have NVME boot drive for reference. Could it be my motherboard problem? My model is Gigabyte A320M K V2.
