  • Hi, 

    Mostly, This issue can be caused by 3rd part applications, incompatible drivers or corrupted system files.

    To narrow down the issue, please first test this issue in Clean boot mode:


    How to perform a clean boot in Windows



    If the issue doesn't appear, you can determine which one can be the cause by using dichotomy in MSconfig. Checking on half of Non-Microsoft service and restart, determining which half of the services cause the issue and repeating to check half of the problematic half services.


    If the issue persists in Clean boot mode, let's run Process explorer to view which program calling service host causing this issue, and we can remove it to see what’s going on:


    Process Explorer v15.40


    Detail steps you can refer this blog:

    How to troubleshoot high cpu in the System process



    Meanwhile, we need to collect the performance trace log by using following tools and upload here for further research:


    Troubleshooting Windows Performance Issues Using the Windows Performance Recorder



    Keep post.

  • Open task mgr,proceses,locate the service with the high usage,R.click on it,select "open file location"

    see where its coming from...Also,one can open event viewer,OS services,locate the error/warning(s)/properties,

    see what the OS says...

  • It is common to have high disk % and cpu % when antivirus is scanning.

    More often though there is a non-Microsoft service that is in conflict with another service.

    This is usually found by turning off all non-Microsoft services.

    This is called clean boot.

    These are the steps for performing clean boot using administrative command prompt:

    Type or copy and paste these commands:

    1) msconfig (in the pop up system configuration > move the dot from normal startup to selective startup > uncheck load startup items > click service tab > in left lower corner check hide all Microsoft services > in the lower right side click disable all > click apply or ok > do not reboot)

    2) taskmgr (in the pop up task manager > click on the start up tab > click on status so that the column sorts with enable rising to the top > right click on each row with enable and change to disable)



    3) shutdown /r (you will reboot the computer so that it is in clean boot)

    Evaluate the performance on your computer in clean boot during typical use.

    Are the boots faster or slower?

    Are the shutdowns faster or slower?

    How has the audio and video performance changed? Is it better, worse, or the same?

    How has the CPU % changed?  Better, worse or the same?

    How has the disk % changed?  Better, worse, or the same?

    Continue using clean boot indefinitely to monitor performance.

    The next step depends on the results of the clean boot.

    Report the results into the thread.

    The next tool that can be used is Windows performance recorder(WPR).

    It can be used to record the times in which you find CPU at high levels or disk at high levels clicking the start button. First it is launched, then customized, and when you see the high numbers on task manager you click start and it records a tracing.  If you learn how to analyze the tracing you will use a verbose tracing.  If you are going to post the tracing in a share link you will use light.  The challenge when posting is find someone that is trained to analyze and interpret the results.  


    Process explorer and process monitor are additional tools that allow you to see what is happening in the background.  But again you will need to learn how to use these tools.




    These are some additional steps that I would recommend:

    1) check the operating system using these administrative command prompt commands:

    a) sfc /scannow

    b) check the drive with chkdsk /scan

    c) and give that it is a HP computer, most come with on board hardware diagnostics.  Overnight you can run hardware checks on most components using the bios UEFI diagnostics.  This is done with a power on and repetitively clicking the F2 or F10 key and then opening the UEFI diagnostics.  The extensive or loop until failure is run which checks the Drive, RAM, MB, CPU, GPU, etc.

    So you will have ruled out any hardware and operating system issues while looking for the corrupt or misbehaving non-Microsoft application.
