Placed in lower priority Q

So my computer has recently shut off in the middle of league games whether it be for updates or some other reason. I got placed in low priority Q once before last month even though i came back to one of the games and won and another time i tried to come back but league would not let me reconnect, but i thought whatever ill deal with wasting 100 GOD **** MINUTES. Whatever, i got through it. It happened again today though, power outage at my place. Comp. shuts off and i restart and get abck into game and win the game. I now have been placed in low priority Q. Is there any way this can be taken care of? Bc i am not going afk out of choice and when it does happen i come back asap and even have won the games since i was only gone for like 3-4 minutes.
