Windows 10: Constant usage of appx 13% of CPU after installing new SSD

Hi all,


I have installed a new SSD (Western Digital NVMe 500GB) to replace the old 128GB Samsung SSD. The replacement process (cloning, setting the new SSD as the booting device) went fine and my system is working as it used to, with one minor glitch. I have a constant 13% CPU usage even when the system is idle.


The Resource Monitor has shown System to be the culprit.

Sysinternals/ProcExp has shown ACPI.SYS to waste CPU Usage.

And here is the WPR Trace file: https://1drv.ms/u/s!AlkkLkBOPhfYhwkaU6U-qUgkDWuA


Any insight on what's causing the CPU usage will be most appreciated.


No generic responses please (Check your drivers, reinstall Windows, etc. etc.)


Thank you!

:)

 

Constant CPU usage

*Original Title: Windows modular installer

I have a constant cpu usage on 25-100%. Even when the computer is doing nothing. The biggest sinner seems to be the windows modular installer. How can i fix this.

I have 2 computers with the same problem. One with win 8.1 and one with win 10.

 

Constant 100% Disk Usage, 60-80% CPU usage. Both happen when idle.


Could you also provide a snapshot of Resource Monitor with selected Disk Activity Tab and checked only System:

i would also suggest running checkdisk and sfc /scannow

 

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I would like to inform you that High CPU usage occurs for various reasons, for example: virus/malware infections, out-of-date drivers, anti-virus programs or other third-party programs, etc;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