There have been a bunch of posts about this but no real answer and I'm almost 100% sure this is software related (BIOS) but ROG is just telling me to RMA the board, which I don't really want to do given all the other threads with the same issue.
PROBLEM: Typically during reboots after any kind of update (Video card, windows, whatever), my POST will hang with a Q CODE 53 and orange light. I have to do a hard power off and then restart to get it to POST again, which forces a BIOS visit where all settings are fine and then restarts normally from there. I have run two different memory modules with the same result. I am on the newest BIOS and controller. I have tried all XMP profiles as well as AUTO. I can't get ASUS/ROG to actually troubleshoot with me outside of just "RMA the board".
Has anyone had any luck fixing this? It works perfectly and runs smoothly except for this issue, so while a nuisance, it's not really enough for me to want to take apart my entire build to most likely get another motherboard that will do the same exact thing.
