Major Game arror

So this is long to explain and even crazier to believe but it just happened. I just reset my computer. After re installing league of legends it lets me play. However as soon as the game starts nothing is loading. After giving up on trying to rejoin the game i go to uninstall league of legends in order to re install it. There i found that the client had been able to run without the program being installed. It was not in my program list so that is the conclusion i have drawn. Then upon re installing the game it behaves differently than earlier. The client let me log in immediately WITHOUT PATCHING. i'm not kidding i thought that maybe the patch was included in the install but after re installing NOW it decides to take 5 to 10 minutes to actually patch to the latest version. So not only was the client open with the game seemingly uninstalled but i was also able to join a game of teambuilder without patching which resulted in me never being able to join the game.
