Hard crash during comp game

I just had a hard crash of my game. I don’t know what caused it, but it happened in the middle of a comp match. I was playing brigitte. The screen just froze, I couldn’t even tab out of the frozen game. Nor could I open task manager to end the program, so I had to restart my pc. In the background I had a google chrome tab open, and of course the battle net launcher. I have a i7 4770, 16gb of ddr3 ram and a gtx680 with the 391.35 driver installed.

Same here. I crashed 3 times today exactly the way you described exept it only happened when i died playing a hero. I never crashed like this before and it also happened to other players i was playing with trought the day.
