Game crashes in loading screen

Game gets to 100% loaded everyone else loads into game, I can hear my mates saying are you in I say nope im stuck on loading screen then I have to force restart my entire computer wait for it to load up sign in again and wait to rejoin by which time everyone is angry because you missed the start of the game. This was happening before the patch not just with me but with alot of people I play with and the fact the Riot have done fuck all about it just rubs salt into the wound. There is a difference between people who dodge games or afk after dying and someone who get stuck on your buggy loading screen riot. DO SOMETHING BEFORE THE PLAYER BASE QUITS.
