Client Crashing Becoming Annoyingly Frequent

I've been playing League regularly since December now, and up until these past few weeks I never really had any problems with the client except the occasional disconnect. Lately, however my client has been crashing more often and this is the 3rd time that I've been put on the low priority queue list when I did nothing wrong. If anyone at Rito knows any fixes or has any suggestions or something could you please comment.
