Same thing just happened to me yesterday. Booted up a game and after about 15 minutes of playing, black screen with no display signal detected to all of my monitors, and GPU fans at 100%. Rebooted, and there's no display, but you can hear the sound if I have my headphones on. Tried pretty much everything I can think of, different psu cables, different computer, different PCIe slot, tried reseating it in the original slot, absolutely nothing worked. Very aggravating since I hadn't even had the card for a week and it dies on a holiday week as well. Luckily I still had my old GPU, but kind of crazy that these cards are just dying so quickly like this.
