Whenever I have YouTube in the background or when I am watching YouTube, it randomly stutters my whole PC. This all happened when I left my computer AFK for a whole day accidentally keeping twitch.tv open and playing. I had a similar problem before I factory reset my PC where YouTube videos didn't buffer very well at all. (YouTube HTML5 player)
 
One thing i found that reduces stutter is to change the power plan of your pc to performance. It means the cpu runs a little faster all the time but your rig can take it... looking at your pc, I can't believe it could stutter at all.
 


I believe it's some kind of driver issue. After I tried to watch YouTube today, it seems to not be stuttery at all. I wonder why it randomly "turns on and off"...
