Ok so I just built a PC but with no graphics card and I'm not able to turn on my PC with my PC case button only on the motherboard button I can turn on and off the PC not just that I don't understand why the board is giving me a vga led light it acts like I gotta have a GPU installed Really Asus when I clearly do not need GPU installed to run a PC and do not want a GPU I use my i9 to run the PC the motherboard is a asus z390 Prime
