Random posting issues and non consistent debug led

[RONJOHNTACO]

So I just got a RTX 3080 FTW3 ultra about a month ago. I didn't have any problems with posting issues until I got my new case (Corsair 5000x) and the corsair commander pro. Now almost everytime I turn on my pc it gets stuck on one of the debug lights. It seems like it's a different one everytime. If it does manage to get past the debug lights and post, then half of the time it won't boot windows. I've tried re seating everything, unplugging all power cables, I also did a bios update and im on the latest version. My guess is either a MOBO issue, bios issue, or PSU isn't powerful enough (I do have the protection on in bios so that if an unstable current hits it should auto turn off), but I can't figure out which one and I don't want to get something new if I don't have too.

Specs-

-MSI B550 Gaming Plus

-Ryzen 5 3600x

-Corsair Vengeance Pro RGB 16GB 3000MHz (Planning to upgrade speed lol)

-EVGA RTX 3080 FTW3 Ultra LHR ( currently set in non OC bios)

-Corsair RM750 PSU

-10 Corsair Case fans

-NZXT Kraken M22 (120mm rad)

-3 HDD and 1 M.2 drive

 

I went back and did a lot of editing on this so if something doesn't make sense or it feels kinda scattered I'm sorry. lol
