What the hell is up with my client?

So I wasn't really sure where to post this, but this can go here I suppose...

Lately, I've been having SERIOUS client issues. I KNOW for a fact it isn't my computer or my internet because literally nothing has changed. I've only started having these problems a few patches ago. I went from an instant 100% loading screen, to worrying about if my client would crash. My client seems to crash at loading screen way more than it ever has these last few patches. My friends have even noticed saying "why do you take so long to load in now?". I truely have no idea and I was wondering if anyone else has had this issue? I have repaired my client so many times, rest my internet, uninstalled and installed league. I've done everything in the book and nothing seems to work. So i'm just truely wondering, what the hell is up with my client rito?
