Windows 10: Ntoskrnl(system) Using 100% disk in windows 10

From ages I'm suffering from this problem. My system boots very slow and after starting itself when I run task manager it shows 100% disk. I tried to solve this problem by watching some YouTube videos but none of them worked. Please help me if you know how to solve this problem.

"System" Service Using 100% disk

Hi,

Thank you for writing to Microsoft Community Forums.

Did you notice any changes on the computer prior to this issue?

What is the make and model of the computer?

One of the possible reasons for this issue is Advanced Host Controller Interface PCI-Express (AHCI PCIe) running with AtorAHCI.sys driver. Please refer to the article:
Task Manager shows 100% disk utilization on Windows 10 devices

I also suggest to try the steps mentioned in the article: Improve system performance in
Windows 10 and let us know the status of the issue.

Hope it helps.
