Leaver buster

I am getting aggravated with the fact that the game crashes. Like the entire game crashes before it even starts and no matter what, I can't join into it. It's not my PC, I'm sure of that, and it's not my internet connection. My connection is at a steady 76 ping no matter what. my lol client even says game crashed but I'm probably still going to get a leaver buster for it and I'm gonna be so mad. For some reason, when my game crashes, it won't let me joinng another game for like 5 hours. This is beyond leaver buster. Every time I log in, it tells me to reconnect but every time I hit reconnect, It says that the game is over but continues to show a reconnect button.
