    System process - high CPU usage after some time


    Hi everyone,
    in Task Manager, the "System" sometimes starts eating 14~20% CPU and that persists until a reboot.
    "System interrupts" (which is a pseudo process?) seems to do the same.

    It doesn't happen from boot, and I don't know what triggers it.

    Google searches suggest a driver may be buggy.

    But which one?

    How can I find it out?

    Could I debug the system process using a tool to see what function a thread is in, for example? Somehow?

    thanks

    :)

  2. After Update to windows 10 (1709 version), My laptop is lagging so much. Laptop model: Acer Predator helios 300

    After the update, your CPU usage can be high for some time, making the system lag and feel slow. I explain how to check for this issue here: High CPU Usage in
    Windows 10
    . That also explains what you can do about it.

    Have you recently installed Windows 10 or any updates? After full build updates are applied, the system can have extremely high CPU usage for several days or even weeks until the backend processes are finished running. I wrote more about how to tell
    if this is the case, and what to do about it, here: PSA: Windows 10 High CPU Usage

  5. It's specific for that device only due to its unique configuration. You just have to wait for another firmware update pack for August.
