As of recently, my computer has been really slow. It used to be quite fast with loading pages youtube and downloading. But now its really slow. Even to load up the pit's threads are a lengthy tast now. And youtube video's are the worst. And I need youtube them sot right now haha, but it always buffers on lowes quality, and I don't have the time to wait 20 minutes for a 5 min video to load. I have a new BT homehub as of about 2 or 3 months ago but it shouldnt be doing this. What could I do? Any fixes to this?
