I would suggest not trying to use it anymore though, and just go straight to the RMA process for wherever they were purchased. Or maybe post on the GN discord to see what they say (annoyingly they don’t have forums or anything, just a discord and subreddit).
If this is just something that’s come from somewhere else, you don’t know where else this mysterious metal may have gone, and there’s a potential fire risk on your hands at worst, or a mobo that could fry any cpus (or memory, etc) plugged in.
If it’s indeed the issue talked about by GN, it’s dead, and if it’s not completely dead, it’s actively dying in an irreversible way.
If it’s some other, new issue, I still can’t imagine plugging it back in will make anything better.
