I've recently bought a new L502X.

I noticed that it sometimes stutters. I first noticed this problem when I was on YouTube watching a video. The audio would stutter and the screen would freeze for just half a second or so. This happens quite often.

I've already looked around forums to see if I could find a fix, but most of the problems there weren't exactly mine.

When I look at task manager, this is what I see after it happens. Suddenly the CPU usage gets really, really high.

 

I've made a video so you can hear, what happens:

Does anyone have any idea what might cause it?
