Loading Screen Crash

This has happened to me not once but three times the past week. I want to say there is something wrong on my end but there is not. I was surfing the internet while waiting for the loading screen to get to Aram. The loading screen freezes on me or goes straight to black and does not load. I also got frozen on the Champion selection screen and had to close my client but then it loaded me into the match. Get your stuff together, Riot. I better not get a Leaver System warning because of this.
