Frozen Screen
So guys i ran into a problem... 
Since patch 8.11 came out i started having a huge problem. When i play ARAM or Ranked my game starts normaly, but few minutes after my screen freezes and i still can recall,move a champion,throw ability but my screen iz frozen. I cant go to my desktop, and i cant shut it down from task manager. Only solution is to hard reset my laptop (hold power button for few seconds). And that is not healty for my computer at all. I already did a repair, reinstalled league, all of my drivers are updated but it still wont work. Before this patch everything was fine.
My components:
-Intel i5-5200 CPU 2.20GHz -4.00GB RAM -64-bit operating system -NVIDIA GeForce 920MX
If u could help me out i would really appreciate it. Thank you <3
