No screen post

[norm6]

Hi, I’m a first time builder trying to get my PC up and running. I’m doing the pre build test trying to see if things are working, before installing everything into the chassis. Things are not working I can’t get my screen to post, I also have qcode 55 on my asus motherboard. Another issue idk if I have to wait until I get a screen posted but, my keyboard won’t turn on. I also have a mac and it lights up when I plug it in there. All fans and rbg light up so I’m getting but, psu and gpu fans stop after a few seconds something but no screen.  Any solutions? Like I said this is my first time building and I’m very novice.

QCode 55 indicates that your RAM isn't installed, or that one or more of your RAM slots are faulty.

 

Double check that your RAM sticks have been fully installed in each slot, and if the QCode persists, try a single stick of RAM in each slot to determine which slot may be faulty.
