Asus mobo stuck at Q Code A9, no display | Tom's Hardware Forum
March 13, 2016 - pull the gpu if your mb has oneboard video and see if it posts. before you do pull the gpu use the usb flashback and put the newest bios file on the mb to rule out a bios bug. bios flashback was already completed prior to the q code staying where it is now.

r/ASUSROG on Reddit: Asus ROG X570 showing code A9 even after removing and turning on with and without HDD, booted with single ram stick and even reset bios settings
January 9, 2024 -
So before all this started my pc was working fine decided to turn up my ram MHZ and then my pc started turning off and on tried flashing bios by using the button on the back but no dice I decided to turn off unplug the pc and take out CMOS battery and it reset my bios setting returned it to factory settingsand it started working again fixed one but another pops out its A9 I automatically boot into bios every time I took out the gpu and tried to see if anything was wrong nothing everything is clean I moved around my ram and the code still pops up and I removed my hdd and it still popped with A9 code. I don’t have another set up to try the pieces individually.
I have run out of solutions from searching google and don’t know what else to try except to remove CMOS battery and see if that works Specs: Cpu: RYZEN 9th Gen 5950x Ram: T force 32x2 64GB 3600MHz GPU: aorus Geforce rtx 3080 Ti Motherboard: ROG Strix X570-E gaming

That code means Start of Setup (according to some other posts about it), meaning the system is entering BIOS setup, which is what it's supposed to do when factory reset. From there, install your OS drive and make sure your Bios is showing the drive installed and in the boot order you'd expect. You should be able to boot into your OS install once that's all done.

When you're in bios, set your boot device to USB (windows installation disk) also check to see if your bios is reading that you have some sort of hard (m.2). If no OS is installed or no hard drive is detected, it usually boot into bios.
