Still can't play league since 5.5

So it has been almost a week since the release of 5.5 and i still have not been able to play a single game. When the patch was first released something went wrong and when i would start league a pop-up would say unspecified error or something like that and would be stuck on 33%. So i followed the instructions online to force a repatch. Still nothing. Then i clicked on the question mark at the top to do the repair files. So it repaired for about 30 minutes and i thought it was fixed. But now whenever i log in, it brings up the client then after about 15 seconds it freezes. And not the client, it freezes my entire computer. I cant move the mouse, i can't tab out. It just freezes, but if i was watching a video or listening to music, the audio will continue. But i still have to force shut down my computer every time. It has been like that for about 2 days. Don't know what to do.
