Video Pausing / Resuming

I am having an issue in my pc that when ever i try to see and video from youtube or any other site its gets in loop of pausing and resuming the video like someone has presses the pausing and resuming button

 

Audio and video pauses automatically

Audio and video pause automatically (and sometimes pause and play) only when I use an internal (Youtube, google) or 3rd party software (windows media player, VLC, films &TVs ).
1. It happens only when I am playing a video or audio.
2. No virus (after scan)
3. Since the spacebar key is usually associated with play & pause, I tried typing something in MS word. I did not see any auto space being generated between 2 letters. (tested for 5 mins)
4. Autoplay and pause (sometimes just pause) occur maybe after 20 seconds. (it is random)
5. I can actually see the virtual pause and play button is toggled. (no other error message is shown, it happens as if I am physically pressing the spacebar key.

6. issues in Windows 10

7. the window also very lag when it happening

8. Driver issues? Which driver is it? Any suggestions or experiences? Please share your thoughts.
