Question Videos freezing for a second when using laptop's iGPU ?

For a while now I've been having a problem in which whenever i watch a video, whether it be on VLC or chrome, the video would freeze for a split second and then resume perfectly.
After doing a hundred random things in hopes of finding the problem all i ended up finding out is that if i use my NVIDIA graphics card this issue does not occur.

I have tried uninstalling & reinstalling my integrated graphics card driver (Intel HD Graphics 630) in hopes that it would fix the problem but it didn't.

If anyone has any idea what the issue could be i'd be grateful if they can help in anyway. , I've also read somewhere the Realtek audio driver might be the issue but I'm completely lost in the topic)
