So am I just screwed now?

So i made the mistake of trying to play league with a faulty computer, It is faulty because it restarts randomly. I normally wait a good couple hours before I play and a lot of the times I have no problems. But now, I have leaver buster because I disconnected in a game, in which I came back(I was gone for like 8 minutes) and now I am tagged with leaver buster 20 minutes. And considering My computer will keep doing this chances are I'll get it again, when I am trying to remove it. So am I just screwed out of my season rewards because of a computer gone bad? That seems lame as hell. WTF can I do? I want my season rewards :(.
