Computer has no beep code no debug lights. Everything spins and lights up. Keyboard doesn’t initialize so I know it’s not POSTing. Monitor works, still haven’t tested GPU, but it lights up and spins fine. System isn’t posting at all, would really appreciate the help.

I’ve also reset cmos, tried all 4 RAM slots.
