For more than a month now I've been dealing with this issue and I have no idea what is causing it.
I am running a Win10 i7 1.8GHz processor, 8GB RAM, and Intel HD Family 4400 graphics. I have updated the graphics driver to the latest version released 4/29/16 and this issue still persists.
I have run multiple diagnostic tests, all passed. I have checked for updates through Dell (manufacturer of computer) and made sure everything was up to date.
Basically, my computer seems to glitch out while streaming videos (Netflix, youtube, etc.) or even playing videos in my own library, while surfing the internet at the same time. Netflix and youtube are the worst for this and if I'm browsing in another tab, while pages load, the sound gets stuttered and sounds like it's playing at about half speed. Even after the other tab loads a page, the stuttering continues, yet there are no graphics artifacts to be seen, it's all audio noises and video just plays at what seems to be half speed for a few seconds, then returns to normal.
I normally use Firefox, but downloaded Google Chrome to check if it was just the browser, but the problem persists through both browsers. I had tried to watch my task manager while these things occur and it seems like when my CPU goes above ~60% is when this happens. I really don't know what else to look at or what other things may be causing this, other than my computer is going to fry itself soon.
Any thoughts or recommendations would be appreciated.
