Internet crashes after each game

This just started yesterday, every single time I die my screen turns completely black for around 1~4 seconds and my ping/connection freaks out, and after each match, my screen turns black and my internet cuts off completely until I close the game. I’ve tried restarting my router, computer, flushing my DNS, repairing the game, and running as administrator and nothing seems to help.
