Windows 10: High CPU usage and periodical running pattern during Screen off, only happend in HDMI 2.1...

Problem ExplainWhen Windows 10/11 system is in screen sleep/black screen state, the CPU maintains high usage for a long time. If the system recovers from sleep state, everything returns to normal. Restarting the system and shutting down have no effect.Later, I reluctantly used Windows Performance Analyzer WPA and discovered that during the entire sleep period, the CPU usage curve was periodic upon inspection! The usage of explorer.exe and NVDisplay.Container.exe kept jumping, showing fluctuating patterns, which was particularly strange! When the standby ended and the screen lit up, everythin

high cpu usage

After downloading windows 10, anytime I run any programs, I get high CPU usage. It does not matter whether it is google chrome, task manager, playing games, whatever. Anything seems to spike the CPU usage. I have already run malwarbytes and my antivirus
programs and find no viruses. Any suggestions? Thanks.

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.
