I'm currently stumped with this annoying problem. I've had this notebook for years and it has always run very smoothly. But for some reason recently it runs horribly sluggish until I either turn on or turn off its WIFI. The moment I turn it off or on it'll immediately go back to normal (running smoothly), but that only lasts for about 5 minutes, then it'll go back to running very sluggish.
I formatted my notebook about a year ago because of this. Could anyone please help me out?
Thanks in advance.
