Weird distorted noise when using PC

[Ak7J]

I've heard similar things from other laptops in the past, but its been becoming more frequent for me recently, where during normal web browsing, youtube, gaming, etc; a weird distorted noise plays and performance goes weird. During watching videos(YT) the audio gets messed up and a frame gets stuck for a few second(s) longer then goes back to normal. When gaming and the distorting occurs, the game audio acts like it does when watching videos, and performance goes from 110fps, to 1-2fps and then goes back to normal. I have no clue what this is, and I'm not sure if its a cooling issue(distorting happens longer during games than video streaming) or something else. Anyone else had this issue ?
