Question GPU not working on my laptop ?

[railtrace]

Laptop model: ASUS ROG Flow X16 2022

So yesterday I noticed that my game performance was not as good as before, so I decided to check GHelper (which I was using) and device manager, and I saw that my GPU had a yellow triangle with an exclamation mark beside it, and when I double clicked it it said something like "this device is not working properly so windows shut it down". I don't have a screenshot of that unfortunately. So, I restarted my computer and now it's just "microsoft basic display adapter" or something, with an error code 31.

I tried installing drivers via both a download from rog.asus.com.cn and the Nvidia app, and neither helped. Now it's also not being detected in task manager. When I switched to the mode that connects directly to the discrete GPU (from GHelper AND Armoury crate - tried both), there were a lot of magenta stripes on the screen and it seems to be still running on the iGPU.

Any ideas on why and maybe how to solve it?

First, check to see if your laptop is pending a BIOS update. Second, see if your OS is pending an update. Third, use DDU to remove all GPU drivers(Intel, AMD and Nvidia) in Safe Mode, then manually reinstall the latest GPU driver sourced from Nvidia's support site in an elevated command.

Don't use third party apps to tell you if you have anything pending an update. Cross reference your manufacturer's support site and the BIOS/driver/app version you have on your laptop at any given moment.

Updated the BIOS (to version 318), no Windows updates pending. Uninstalled display drivers with DDU and reinstalled them manually via download from Nvidia's support site. After a restart device manager still doesn't like it (Code 43), and no sign of it in task manager either.
Might this indicate a hardware problem?

Ok I can be pretty sure that there's a hardware problem now. Didn't expect a ROG to be this unreliable
