Windows 10: High cpu load on startup Windows 10

Hello,

for my brand new notebook Lenovo Ideapad 5 on startup, after the user login, i see a high cpu use by the System process ntoskrnl.exe.

It happen at every reboot, no exception but if started on safe mode it doesn't happen.

Windows 10 is up to date, fresh installed few days ago.


The following is the windows performance analyzer screen for about 1 minute of recording:






I tried to disable the wireless network on bios and disable all the services on boot using msconfig but the problem still remain.

I tried also to install the nvidia driver from the nvidia web site and also install updates from intel web site, without success.


Anyone can help me?


Thank you

:)

windows 10 high constant cpu usage

Hi Steven,

Thank you for posting your query in Microsoft Community.

I understand the inconvenience you are facing. Let me help you in resolving the issue.

I would appreciate if you can provide us the following information to help us understand the issue better.

• Did you make any changes to your computer prior to this issue?
• Which anti-virus program is installed on the PC?

I would like to inform you that High CPU usage occurs for various reasons, for example: virus/malware infections, out-of-date drivers, anti-virus programs or other third-party programs, etc;

I suggest you to follow the methods below and check if that helps:

Method 1: Windows has a built-in troubleshooter to check and fix issues with system. I would suggest you to run this troubleshooter to check if the issue is with your System
Maintenance.

• Press Windows key + X on the keyboard.
• Click on Control panel.
• Type “Troubleshooting” without quotes in the Control panel
  search box.
• Click on Troubleshooting and click on View all.
• Click on System Maintenance troubleshooter and follow the on-screen instructions.

Method 2: Check if the issue resolves in
Safe Mode.

Refer this article to boot to safe mode:

Steps to reduce the CPU usage.

1-Press "Ctrl," "Shift," and "Esc" on your keyboard. This brings up the task manager without any intermediary screen.

2-Click the "Processes" button on the task manager.

3-Click the "CPU" column header until the arrow next to the label points down.

4-Right-click a program you recognize that uses a high percentage of the CPU and click "End Process." Click "End Process" to reconfirm. This eases up on the CPU's load. Use this step if you're not using a process or if the process has stopped responding. Do
not use this procedure for windows processes.

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.
