intermittent 100% CPU usage


Recommended Posts

This occurs most often when I sign into windows 10 home HP Laptop (Ver. 2H22  - OS Build 19045-2965). The computer slows to a crawl and becomes unresponsive. Checking Task Manager indicates the MWB is at 100% CPU. It alternates this condition with Google Chrome.

After several minutes, the system returns to a normal state, but then acts up again at random. Not sure what causing this phenomenon, however; I was wondering if I should disable Windows Defender, but my Alienware desktop Windows Pro computer does not have the same problem and works well with Windows Defender. Anyone have any ideas how to troubleshoot this issue? This has been plaguing me for many months. I initiated a clean windows install yesterday and it is still occurring.

Hi,

Thanks for posting in the Malwarebytes for Windows Help forum.

If you are having technical issues with our Windows product, please do the following:

Malwarebytes Support Tool - Advanced Options

This feature is designed for the following reasons:

  • For use when you are on the forums and need to provide logs for assistance
  • For use when you don't need or want to create a ticket with Malwarebytes
  • For use when you want to perform local troubleshooting on your own

How to use the Advanced Options:

Spoiler
  1. Download Malwarebytes Support Tool
  2. Double-click mb-support-X.X.X.XXXX.exe to run the program
    • You may be prompted by User Account Control (UAC) to allow changes to be made to your computer. Click Yes to consent.
  3. Place a checkmark next to Accept License Agreement and click Next
  4. Navigate to the Advanced tab
  5. The Advanced menu page contains four categories:
    • Gather Logs: Collects troubleshooting information from the computer. As part of this process, Farbar Recovery Scan Tool (FRST) is run to perform a complete diagnosis. The information is saved to a file on the Desktop named mbst-grab-results.zip and can be added as an email attachment or uploaded to a forum post to assist with troubleshooting the issue at hand.
    • Clean: Performs an automated uninstallation of all Malwarebytes products installed to the computer and prompts to install the latest version of Malwarebytes for Windows afterwards. The Premium license key is backed up and reinstated. All user configurations and other data are removed. This process requires a reboot.
    •  Repair System: Includes various system-related repairs in case a Windows service is not functioning correctly that Malwarebytes for Windows is dependent on. It is not recommended to use any Repair System options unless instructed by a Malwarebytes Support agent.
    • Anonymously help the community by providing usage and threat statistics: Unchecking this option will prevent Malwarebytes Support Tool from sending anonymous telemetry data on usage of the program.
  6. To provide logs for review click the Gather Logs button
  7. Upon completion, click OK
  8. A file named mbst-grab-results.zip will be saved to your Desktop
  9. Please attach the file in your next reply.
  10. To uninstall all Malwarebytes Products, click the Clean button.
  11. Click the Yes button to proceed. 
  12. Save all your work and click OK when you are ready to reboot.
  13. After the reboot, you will have the option to re-install the latest version of Malwarebytes for Windows.
  14. Select Yes to install Malwarebytes.
  15. Malwarebytes for Windows will open once the installation completes successfully.

Sounds like Malwarebytes is scanning.

Please do the following so that we may take a closer look at your system.

Sorry 'bout that...

HP Laptop Model # 17t-bs000 CTO    

Purchased new and received on 8/10/17 Registered with HP on 8/14/2017

Checked the support page after the clean install several days ago. After entering the

model number, a list of drivers appeared.  Some were older than my machine, so I

chose a feature on the site that scanned the computer to determine if new drivers are needed.

The results indicated that none were. Checking driver update via Device Manager has never

yielded very good results for me. After searching for an updated driver, the standard reply has

always been that the best driver is installed. What do you think?

Uninstall the following.

HP Support Assistant
HP Support Solutions Framework

It is crashing in the logs as well.

 Then please grab a screenshot of your device manager and post it here.

The items listed under "Other Devices" have no drivers installed.  According to a post I found, these drivers are required: https://h30434.www3.hp.com/t5/Notebook-Software-and-How-To-Questions/PCI-Data-Acquisition-and-Signal-Processing-Controller/td-p/7955420

It's been a hectic day today, holiday preparations keep interfering with our discussion. I will try to get back to this tomorrow, if not, for sure Wednesday morning. Thanks for your patience!

 

 

I feel you. Between the wife, kids, and grand-kids it's difficult to stay on task

Yes, getting all the correct drivers installed would be a good thing. Using the product vendor is the best method as well

Hi Taskman:

I don't have sufficient privileges to read your attached mbst-grab-results.zip file, but note that the Win 10 v22H2 Build 19045.2965 (KB5026361) was released on 09-May-2023 .  If your Win 10 OS is fully patched Windows Update should have delivered the KB5033372 monthly cumulative update (rel. 12-Dec-2023) that patches your OS Build to 19045.3803.

Go to Settings | Update & Security | Windows Update to see if Windows Update is trying to download / install an available update, which might explain at least some of your high CPU usage.

Porthos - 

 Both drivers installed, so far, so good. Do you mind if we break at this point? Need to prepare to travel out of town for the holidays. The Christmas cookies are not finished and the pies await! I should return on or about Dec 27 - 28.

Thank you vey much for your help, all is looking good with this machine so far! Merry Christmas!

... KB5033372 installed on 17 Dec and KB5032339 installed on 19 Dec, OS build 19045-3803 confirmed.

Hi Taskman:

KB5032339 is the Cumulative Update for .NET Framework 3.5, 4.8 and 4.8.1 for Windows 10 Version 22H2 released on 14-Nov-2023 with the November 2023 Patch Tuesdays updates (NOTE: Patch Tuesday always occurs on the second Tuesday of each month; this month's December 2023 Patch Tuesday on 12-Dec-2023 did not include a cumulative update for .NET Framework 3.5, 4.8 and 4.8.1).  I'm not sure, but it sounds like Windows Update has been trying to install a backlog of available updates on your system, which might have been the cause of your high CPU usage.

Have a safe and happy holiday!
