Loading into game but can't see the screen

So I sometimes load into game and the client bugs out on me. After I just played a game that was fine. So I go in champ select pick my champ and and runes and everything is fine. But when it goes to go into the loading screen it messes up.SO I try to restart the client and it still loads me into the game. But I can not see the game but I can here the sound and I get leaver buster plus its in my placements. I did not intentionally afk and feel really robbed of my placements. Its not the computer either because I just played a game where everything was fine. If i could at least get my placements reset or something I'm kinda for a loss. I even used the hectech repair tool.
