I have been using the card for about 4 months now. No problems so far. Now I have the problem, from one day to the next, that after some time (can be 5 minutes or even 40 minutes) the fans of the graphics card turn up completely and the screen goes black. This also happens during normal operation, without me opening any performance-intensive programme/game. The only solution is to shut down the PC manually and restart it again. Does anyone know the problem and have any suggestions for a solution?
