Hello, I posted a few days ago about my PC having issues with reboots and crashes, It was possibly the GPU,PSU or motherboard. But lately I have been noticing my GPU changing color on its backplate to a golden/bronze color. Why is this happening and should i be worried? Can this be the PSUs fault?

The temps are 30c at idle and around 60/80c stressed. It is an RTX 3080 10gb. Color has changed within 3 days.

Here is how it looks: View: https://imgur.com/oDFzDtW
