Client Crashes(riot pls respond)

So ever since Dynamic Que has come out, I've had really bad problems with my client crashing at random during it. Some of the issues being freezing while selecting a skin, freezing while loading in. My client will crash and then it will give me a wait timer for my next game and I lose LP. Now this hasn't been a problem for me since its not that much LP. BUT, Just now my client froze once again and it gave me a 30 minute timer and I lost 10 lp anybody know how to fix this problem? Thank you!
