Hi, I realize that when my pc is in idle for some time the system process uses up to 5% of the CPU, I know it is not much, but if you look at Ryzen Master it is up to 4.6Ghz, 1.48v and 50 degress in IDLE.
The strange thing is that it will continue like this until I start using the PC as soon as i open some app the usage come back to normal

What is happening? i alredy clean the cmos and i have the last version of bios F32 (X570 Aorus Master) also i have all drivers up to date and i check the device manager and it seems to be ok

Look in the other Task Manager tabs, look in Resource Monitor, look in Process Explorer.

Try to identify what all is running while the PC is "idle".

You may need to download Process Explorer via Microsoft's website:

https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer

Task Scheduler may also provide some clue. Look for triggers that are set up and likely to initiate when the PC/CPU is "idle".

You may need to leave the applicable windows open and just observe when the PC goes into some "idle" mode.

Look for what changes. May take some trial and error to discover the applicable view point.

Found a few links:

https://helpdeskgeek.com/help-desk/why-ntoskrnl-exe-causes-high-cpu-and-how-to-fix-it/

And from within this Forum:

https://forums.tomshardware.com/threads/having-a-problem-with-ntoskml-exe.3672272/

Read both links and google for a few more.

No need to take any immediate action. Objective is to just learn more about what may be or is happening.

There are a couple of immediate things you can do:

Try running the built-in Windows troubleshooters. The troubleshooters may find and fix something.

Then "sfc /scannow" and "dism" may prove successful.

Avoid any fixes involving the registry or installation of third party software claiming to fix the problem(s). Some of those apps show up no matter what problem is occurring....
