Game Crash

​My game crashes at least once or twice a day, it brings me to the reconnect screen, so i press it, and it will crash again, then when i finally load in its already 2:30 - 4 minutes into the game

I get leaver if my team remakes, and its so annoying to get leaver, and idk when its going to happen. i don't want to constantly having to be in low priority queue for 20 minutes for 5 games. Riot, if your reading this please fix this problem, i'm not the only one who has this problem, I have 2 other posts about this, and other people have commented on them saying they have the same problem. We are getting annoyed about this.
