Hi,

I have an old laptop Dell Latitude E4300 model number PP13S. I've been using it for documents work, movies etc. A while ago it started to make a weird problem - every 4-5 seconds it "lags". I dont know if this is the correct term. You can check the video here

. Listen to the sound - it "brrrrp"s... 🙃

On the task manager it doesnt show any CPU performance peeks ever 4-5 seconds something like that. I am not sure if the problem is with the CPU.

It's doing it on any music or video on:
  • winamp
  • VLC player
  • K-lite codec pack with media player classic
  • Windows media player
  • online radio stations
  • every video or music on any website on chrome, brave, firefox, internet explorer
What I did so far:
  • installed Windows 7 x86 and x64: same problem
  • Installed Windows 10 x86 and x64: same problem
  • the bios is updated. I've tried with older versions too
  • different drivers: older and latest versions for the model for every component
  • external usb sound card
  • I've changed the HDD with a better one
  • I've tried brand new SSD
  • a specialist dissembled the machine, cleaned it and change the thermal paste
  • I've tried it without any drivers
I want to say that I am not a computer specialist. My curiosity drives me crazy.

Please can You give me any other ideas to try.

Thank You
