Question Black screen in game: have to cut the power off

Mar 21, 2021
Troubleshooting: My computer crash when I play but never during benchmarks. The problem occurs randomly: sometimes on the main menu, sometimes after 1 minute of play, sometimes after 3 hours of play, ... I got a black screen and the fans are running at full power until I turn off the power (reset doesn't work, I have to cut the power).

I had a GPU that crashed only in one game, a racing simulator. In any other game it worked without any problem.
It was a RX480 Strix, I sent it for warranty and after analysis they sent me a new card. They cannot find the reason for the problem.
If your card have warranty you should contact the manufacturer
