Question GPU suddenly stopped.

[Sekrio]

Last night my computer was running fine.
Today when I booted I noticed it only displaying one monitor, my log in screen looked like a lower hz as well.
I looked at my pc and noticed that the gpu was lit up but the fans were not spinning, My pc is only using either my onboard graphics or my intel graphics.

I’ve tried dusting out my pc, Uninstalling display drivers and reinstalling, Disabling intel display driver, Updating windows.
The fans work for the first few seconds of boot but stop once at the login screen.
These are the specs, I’m hoping someone may be able to help me troubleshoot.

(Update) The gpu is working normally, The only problem now is that my second monitor is not working.

How old is the PSU in your build? Did you remove GPU drivers using DDU? With regards to reinstalling the GPU driver, did you install with the latest version in an elevated command, i.e, Right click installer>Run as Administrator?

I did use DDU and ran nvidia as admin,
I believe the problem was a my second monitor cord just stopped working.
which changed my nvidia control panel preference from gpu to cpu.
everything is running fine now, just cant use my second monitor
