screen freeze

Hey , so there's a very common problem happening in game which is the screen freezes and you can't do anything but restart your pc it's getting more and more annoying since riot did nothing to fix this and people been complaining for months about this and I keep getting 10 min banned and low priority queue and its not even my fault. any suggestions and any new solutions?
