So i have a new-ish 2010 Toshiba satilite Notebook with a T-4300 Intel dual core processor at 2.1 GHZ and 4 gigs of DDR3 ram 500 GB harddrive and all that. So i have been playing Lol for like 6 months now and all of a sudden i go down to like 6 FPS and i check my task manager and my CPU is at 100% the only other thing i have open is Skype and maybe the itnernet browser, the cpu usage iwll go down like 30 seconds later. Anyone know the cause of this?
