System process using too much CPU

[d3mona]

Hi,

 

I'm using Windows 10 64-bit on ASUS G750JS with i7-4700HQ running at ~3.3GHz and 16GB RAM. The system process "ntoskrnl.exe" is using around 15-20% of my CPU non stop no matter what I do even after complete re-installation of windows.

I have checked here and there for ideas on what to do, but nothing worked.

 

So far I have checked that all my drivers are updated. Installed all available updates for windows 10, stopped "superfetch" and some other services, did a full system antivirus scan, but the problem remains.

 

Does anyone have any ideas ?

About half way down "SpiritX MS MVP" posted a pretty detailed reply.  His/her instructions are tedious, but should eventually get you to an answer.

Have you left the PC on for a few hours after you first installed windows so that it can finish doing whatever it is trying to do?

One thing he missed is drivers. Drivers goes under 'System'. So, if their is a driver bug or poorly coded, it can spike 'System'

I have looked at that article and the suggestions are to reinstall drivers , do clean boot and run scan and repair commands.

All drivers look up to date. The clean boot and restore/scan commands did not help.

It ran for more then a few hours.

The only thing I can do with drivers is to search in the exact manufactures for newer drivers then the one I have , but I'm not sure if this will help.

More specifically he recommended starting with a clean boot and incrementally adding drivers and services back in until the problems reoccurs.  That should tell you what drivers or services are hanging up.  It could end up being really tedious, but it should point at something specifically eventually.

I have disabled all services in the "System configuration" (msconfig) and still get 14-15% CPU usage without running any programs on my own.

I have started testing random things and after removing one of my hard drives now everything is back to normal.

I guess I will have to find out what is wrong with that drive.

 

EDIT:

I looks like there is some problem with my caddy that I used in place of my DVD as swaping the HDD did not change a thing.

I guess I will have to check what is wrong with the caddy ( or the SATA port for it ... ).
