I already have my maximus IX formula over 3 years know, but recently I wanted to go into my BIOS and adjust settings however when I tried it no matter what I did, I got the post screen, pressed F2 and it just gives a black screen. I also tried to go in with spamming F2 or DEL but none worked. I'm really frustrated because the only way in is pressing the clear CMOS and go into the setup after it gives the CPU fan error. (AIO sits in AIO header and I disable CPU fan detection)
I can just boot normally in windows, I just cannot go into the BIOS.
