Question Help! Pc shutdown after several mins in bios

[Mrsir2024]

I have a pc with

13900k cpu
Asus z790 e mb

The pc will shutdown after several mins. So, i try to do the process of elimination. after removing everything, the only thing left powered is the mb with cpu and 1 memory stick. i have tried replacing the psu, clearing the cmos, try two of my memory stick one by one, reseating the cpu. the cpu is not overheating in the bios since it says 39 degree. now if i press start button on the mb, it will boot up after 1 minute and stay in bios for like 10 mins, then just shutdown. any help is really appreciated. i really don't knwo what to do.

Need full system specs, including make/model of the power supply.;

do you have an OS (windows) installed? since you didn't mention about a storage device in your specs, I assume you don't.

why does it straight up go to BIOS if you do have and OS? (or are you manually going to BIOS?)

Q) what were you doing for 10 mins in the BIOS? just staying there without moving the cursor/selecting options or were you doing something there and while doing something it shutsdown?

if you weren't moving the cursor or going through some menus, it might be because it's not being used and since no OS drive to boot from, it just shuts down. to verify this, try going through some menus in the BIOS [don't change any setting, just look] and see if it still happens while you're *using* the BIOS.

lastly, install an OS onto a drive and then boot from it to see if you encounter the same issues. hopefully not.

GL!

Thank you for the suggestion. I do have an os. I only stay in bios because i want to see if shutdown happens. I noticed that everytime my pc shutdown and boot up again, the csm setting in bios is always set to disbaled even i set it to enable manually before. And i also find that when i run without gpu, i cannot enable the csm also. I need the csm to access sata ssd where my system is.

so, shutdown doesn't happen when booted into the OS?

as I asked before, what were you doing in the BIOS? just waiting there without doing anything or actually 'using' it?

Sry for the confusion, the shutdown started in os. I am just doing tests to narrow down it to certain components. So,I am just waiting in bios to see if shutdown happens. The possible reason that I have right now is that the pcie port might be damaged. Since every shutdown cause the CSM setting to be disabled, which is the same behavior when mb runs without gpu. Maybe every shutdown is the gpu dismounting from the mb.

Remove SSD and test it. And also test a different PCI slot with the GPU. And actually remove the GPU completely and try it(I think you are doing that already if not do it).
