I just bought a new motherboard and swapped it for my old one. I noticed my old one had the same issue that when the computer would boot it would just stay black screen then it boot straight to login screen. I have tried spamming Del to get into bios, but the computer just will not boot at that point everything will be running, but nothing displays. If I just let it boot it takes maybe 10 seconds to fully boot It doesn't bother me too much but I am worried a little, since I have not been able to configure my bios settings with the new motherboard.. I also recently got a new PSU aswell since my old one died.
