DC at loading border???

So idk if anyone else has this exact problem but it seems like most matches I attempt to play, champion select goes smooth but then when it ends and the game is loading in, I always seem to crash as the league logo never shows up and I can never even get to the border screens. If i do, then the game loads mad slow and I feel bad for making everyone wait like 10 min. Game ran normally before but it does this exact thing once in a while and in the past I have reinstalled lol and it was the solution but this time its not helping!! HELPPPPPP
