100% cpu usage , laptop lags and freeze up when streaming and moving mouse cursour

Hi im having problem with the fact that my cpu skyrockets when im streaming from different sites like netflix , hbo and viaplay.. if i have full screen and move the mouse the pc freezes up for a couple of seconds ..  but works fine for around 20 minutes if im not moving the mouse  but because of the constantly pushing the cpu at 100%  it starts to lag and loose fps after around 20 min ..  ive updated drivers for both the bios ,sound and graphics .. i have already did send the laptop to service once but  it just came bak  with an updated bios version.  hardware failure ????

Please use Task Manager to see which one is the culprit. We then can go from there.

I know for a fact that the internet browser uses a fair amount of the cpu.. But over 70 percent cpu use on, chrome, Firefox and edge. Ive tried with and without hardware acceleration .  Without hardware acceleration it drops to really low fps directly and so dramaticky so its not an option.. And still the cpu usage is above the normal values.  In idle Windows i have a average use of vram around 45 %. When im using hdmi cable to project to The projector ive noticed a sound from The laptop itself, almost sounds like when you push down the mouse button on The mouse pad. This sound comes usually when i start up video streaming. IT sounds like it comes from The area Just below the speakers on The laptops right side. Its not to far away from The hdmi output. Its not an electrical software sound but more of a "mechanical" sound if you understand what i mean.. Could this a faulty gpu/video card? That it is some electrical shortcircut or transformator i hear???
