his specs are fine, stop saying its his computer, those parts are less then 4 years old...holy crap.
with an ssd running in it (no matter the size) his cpu wouldn't be spiking that much without something in the background.
Its defiantly something java, look at the gif... I'd suggest completely removing all forms of java and just doing which ever your computer is running -> "my computer" -> "computer settings" and look at what bit you run. Then download just that one, though i honestly doubt it will fix much, you probably need to move it to a lower priority so i can't hog like that.
also if you run -> msconfig and hide all by microsoft, disable all, then open startup and disable anything thats not NEEDED it will help a poop ton man.
