    Daily system CPU usage being used at 18%-20% ntoskrnl to blame?


    Okay so since I have done a fresh install of Windows on my ASUS ROG laptop and I have been noticing that daily for about 10-minuteness at a time. I have been getting my system using my CPU and ntoskrnl according to process explorer is the cause. I have also done the tests of enabling and disabling certain devices in device manager and no good so far. I have downloaded and used Windows performance analyzer for two minutes. I would like to send the file but it says its too big for this site so PM me.

    :)

    System using 20% cpu

    Hello,

    Try to identify the process creating this issue.

    Download Process Explorer from Microsoft:

    Process Explorer - Windows Sysinternals

    Run the tool then select the system process, right-click and select Properties.

    Switch to the Threads tab. This will show which file is using the excessive CPU usage, from which you can then attempt to diagnose it.

    You can also refer suggestions mentioned here:

    Let us know if this helps!

    NT & Kernel System (ntoskrnl) using High CPU

    As suggested, I created a WPR file to log what may be wrong in my system.

    The system process is always using up to 20% of CPU, even when computer is idle.

    This is the file:

    Thank you very much for your assistance
