Question R9 380 Nitro dying or something else?

[Juaniblanco]

Hello everyone, sorry to bother you all.

So, about a month ago, i started to have some issues with my GPU (or at least that's what i think it is).
Playing GTA normally when out of nowhere the game crashes and I got a message saying "Driver has stopped working but recovered" or something like that (can't remember precisely)
I started it again, and then it al began...
M2 drive started to "reconnect" every 2 or 3 minutes, at the same time as the game would show a completely black screen for a couple of seconds.
I decided to try a much minor gpu intensive game, CSGO.
M2 kept reconnecting and csgo freezes. I used to have the csgo on the m2 and because of this, the game would crash everytime the m2 disk reconnected.

I decided (don't ask me why, i quite can't remember the reason i did it) to re-adjust the m2 and try to reinstall GPU drivers.

After doing that, m2 stopped reconnecting (neither on csgo or gtav)
but the video card kept on failing showing black screens for a couple of seconds, sometimes dropping frames...

Tired of this, i wnet out to watch youtube, and noticed that whenever i launched it to full screen, a half green screen will appear for a couple of seconds before showing the video normally.
When running a video on my second monitor, it would behave weird, like for example, the video would be shown like 3 times (like the same image multiple times on the same screen but at the same time, cannot explain exactly, but like you select a vertical photo and fill a 1920x1080 screen with it multiple times)
Whenever i minimize youtube and then maximize it again, then again it shows this weird green screen. It kinda reminds me the old vhs videoclips.
LAST ERROR I GOT WAS A BSOD: "Internal Power Error"

A friend of me told me that maybe some connectors on the cpu of the gpu might be damaged and then proceeded to do a rebailing i think its called?
we tried the gpu at his home, and everything was working like a charm.
No green screen. No multiple images, no nothing.... all happy till i got to my house and the failures where there... What can this be ?
Sorry for the long test.

Ok little update.
M2 drive sometimes keep failing, sometimes it keeps working like nothings wrong.
Apart from that, GPU is still giving some erros. I have underclocked it to try and see if that helps but nope.
