Question Windows not detecting GPU

Feb 9, 2021
When i was gaming the computer suddenly shut off.
When i turned it back on i dont get any display from the gpu.
And this have been the problem ever since.
The GPU`s RGB and fans do get power, fans spin and RGB light up.
I am able to enter bios and windows from onboard HDMI.

Prior to this i have noy had any issues.
Anyone have any other tips or have the new GPU just died out of nowhere?

This is some troubleshoting i have already done:
Tried another 850w psu with diffrent cables.
Tried the other PCI-e slot on MB.
Cheked and reconnected other plugs on MB.
Tried onboard HDMI "I do get image trough there"
Tried resetting the BIOS.
BIOS is not detecting GPU either.
