    I have a Dell Inspiron 15 5000 series laptop running windows 10 64 bit. Recently the curser started jerking when I would try to move it, the sound is very crackly when I watch a video, and sometimes I get a vibration and noise from the laptop. The computer is also running slow.

    When the problem is occurring, open Task Manager and watch the cpu usage. If the cpu usage is high (ie: at or near 100%), then something is running using all of the cpu. You can check the processes tab to see which process is using the most cpu. The cpu running at 100% can cause all of the symptoms which you have reported.

    If could also be that the cooling system is dirty or failing, and the cpu is being downclocked (ie: slowed down) to prevent overheating and damage.
