Asus Bios Boot Problem

Hello guys,

Hopefully, this is the correct forum to post this problem too. I recently modified my pre-built pc by changing the case to something with more airflow. Building the PC was fine however I have encountered a problem during the boot.

Every time the PC boots it loads the ASUS overclocking splash screen then loads to the bios instead of windows. No error is shown in the bios and as soon as I save & exit the pc boots to the windows login. This problem does not occur when the PC has been reset only when shutting down.

I have tried changing the boot order in the bios, reset the CMOS and made sure my keyboard isn't the issue. My Q-Code shows A9 during the bios "Start of Setup" which doesn't help towards the problem. Although the issue isn't major its just annoying booting to the bios then saving & exciting just to get to Windows.

FYI. my motherboard is an Asus Z170 Deluxe and I have attached a photo of the bios during the boot below. (my SSD contains the windows install)

Hopefully one of you guys should be able to solve this issue.

  1. just by any chance, was this happening maybe before you did your modifying? Certain motherboards have certain switches that can enable certain bios features directly onto the board. Check to make sure you didn't accdientaly hit one of the switches if your board has any. If your motherboard has a dual bios, then it may be something with the second bios itself. You will have too look really hard btw because switches on the mobo can be very miniscule. If that doesn't work, then download a fresh copy of the stock bios and reflash it. If not, then try updating the bios.

    Hello, I recently had the chance to test your solutions and unfortunately, the 'bios' is still being booted first. First to answer your question I didn't have this problem before I modified my PC.

    I have moved all my motherboard switches back to default as shown in the manual as well as re-flashed/ updated my bios and the problem still occurs. I'm really not sure what to do next :/
