Recently I just upgraded my Mobo/Processor. It ran perfect I could League of Legends and Runescape at the same time, while running music from youtube. Then I started to drop frames, and I was confused so I would just close down one of them and continue to play (it would be fine). Now when i was just playing LoL my frames continued to drop and its just League of Legends. I reinstalled my OS and it didn't help.
