    System process,: ntoskrnl.exe , high CPU usage, BSOD


    Hi

    I just reinstalled windows, till format it works totally fine.

    Now when i plug in an external display via HDMI Process process name: "System" starts to use CPU pretty a lot 20-40%. In detials its: "ntoskrnl".

    While using display it can lag on some actions like: notification bar: lags, i can wait TOO LONG to unfreeze or just unplug hdmi and it starts to work fine.


    Just in case: i installed/reinstall all drivers according to Intel/Nvidia graphick.


    My last BSOD was:

    system process high cpu usage

    Hello,

    To fix high CPU usage issue, please refer these steps:

    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.

    Also refer: [FIX] Windows 10 High CPU Usage Problem

    Let us know if this helps!
