LoL freezes whole PC in every Match...always at the same time

Hey all, so since like 2 days my PC freezes in every single LoL game for no reason. Its always around the 10 minute mark after joining a match, then i get a complete white, green or black screen + soundbug. This forces me to restart my PC. After that i can play the whole match, but in the next match this same crash will happen. All other Games and stuff work without any problems. Anyone facing the same problem or have any ideas whats causing it?! Running on Win10 with pretty good PC Setup. Thanks for any replies <3
