Launch Bug

Every time I want to play League, I have to launch is several times (Maybe 4-5). I start up the patcher and I press launch, then the patcher disappears and it's not on my taskbar. I start it up again and it says LoL is already running and asks me if I want to close it. I say yes and it starts up. I have to do that 4-5 times every time I want to start up League. I have Windows 7 if that has to do with anything. This started happening like a month or two ago. I don't remember doing any large changes to my computer in that time frame. Any way to fix?
