Which country? How we could know where is it? If you have no idea give it to service or people who has experience.You need to be patient and open cards, if card was never opened then you should be more careful to not tear thermal pad, I do my own service and enjoy it always happy to repair any card and give it back to life again.
Yeah, my card was probably already broke. It stopped posting video. Probably overheated and died.
I have older 1080ti's I'd like to rehab, and I am not as knowledgeable as someone who does it a lot.
