Hello ,
Good to see you in Microsoft Community.
Firstly, could you let me know the specific system version (OS Build)? You can check it by pressing Win + X > System > Windows specifications*, click “Copy” and paste it in your next reply*.
Would you please describe your problem in detail or send me a screenshot/photo of it, and include it in the next reply to help me understand your situation better?
Or you can Perform a clean boot (microsoft.com) to see if it is normal, this is a troubleshooting step. In this mode, we can further confirm whether it is caused by system problem or third-party software or personalized settings. So, please be patient.
Disclaimer*: A “clean boot” starts Windows with a minimal set of drivers and startup programs. It helps to determine whether a background program is interfering with your game or program and to isolate the cause of a problem.*
These steps of "clean boot" might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by-step so that it will help you get you back on track.
If your CPU is still highly utilized when the computer is idle, you can set the minimum CPU usage in Advanced Power Options. Win*+* R to open "Run", type 'powercfg.cpl', press Enter to open the Power Options*, click 'Change mode settings' to the right of the current power plan > "Change advanced power settings", if you are unable to configure it, click "Change currently unavailable settings" above, and set the value for the CPU state.*
If anything is unclear, please do not hesitate to let me know.
