Windows 10: Windows 10 System Task High CPU Usage After a while (45 mins 1 hour since a restart or boot up)

Hello, lately the System task (ntoskrnl.exe) is using 17% of my cpu (average) after 45 mins or an hour. I've looked and looked but cant find a fix. I've ran antivirus (malwarebytes and webroot) but nothing is showing. Any help is appreciated. My Machine is the Asus ROG GL753VE.

Windows Explorer high CPU Usage in Windows 10

Hi Andrew,

Usually, too many background processes can boost your CPU usage. Since you already disabled the apps that are not necessary on startup,
we suggest checking the applications running once you have successfully boot Windows 10. To do this, simply follow the steps below:

• Click on the Start button and type Task Manager on the search box.
• On the Task Manager window, you should see the programs running.
• Click on the More details drop-down button to see the total number of apps running and their real-time CPU usage.

From there, you should see what applications are running on high CPU usage. You can also
restart the Windows Management Instrumentation service and see if your CPU performance will improve. Follow the instructions below to restart the service:

• Click on the Start button and type Services.
• Scroll down the list and look for Windows Management Instrumentation.
• Right click on it and select Restart.

Should you have further questions, please let us know.

 

High CPU Usage Problem

Hello,

SvcHost.exe is a system process that hosts multiple Windows services in Windows Operating Systems. If there are multiple instances of svchost.exe in Task Manager, it could be that there are multiple third-party applications that are running in the background
services.

As a first troubleshooting step, we suggest that you boot your device in Safe Mode and see if you are still getting a high CPU usage. You may follow the steps here on this
link to start your PC in Safe Mode.

Keep us updated with the results.

 

High CPU usage

Hi Tusar,

The Task manager shows high CPU usage for core Windows process which can be used by other application. In order find out which applications might be using more resources through these services, I would suggest you to open 'Resource monitor' and check. In
task manager, go to the 'Performance' tab and click on the option 'Open Resource monitor' option at the bottom. Click on the CPU tab and then select the processes which showed high CPU usage in task manager. No expand the 'Services', associated handles section
and post us a screenshot so that we can check the details and help you accordingly.

In the meantime, I would also suggest you to boot the PC in safe mode and check if the issue persists. Refer to this article:
