What the hell?

I just started a match (my first one in a while) and the first weird thing that occurred was an unnaturally long load time. My pc is pretty bad, but not bad enough that the games takes 6 minutes to load. Then when the game FINALLY connected, I bought my items, headed for the red buff, and the next thing I know, my character was on autopilot for the enemy base. It was just constantly moving towards through the mid line and wouldn't stop no matter what I did. Of course being a level one the tower killed me instantly. My team then freaks out calling me a feeding troll. I respawned, tried to go to the jungle again, and just kept making a beeline for the enemy base again. After two deaths I simply had to leave the game. I have heard of other people with this exact same problem. Riot you need to fix this ASAP.
