Welcome to the HP Forums 🙂


I read the post regarding the computer being super slow and having performance issues. It will be a pleasure to assist you here.


To provide you with an accurate solution, I'll need a few more details:

  • Have you run complete hardware diagnostics on the computer to eliminate hardware failure?
  • Did this happen after a windows or software update do you remember?
  • Have you run virus and spyware scans on the machine?
  • For a start, please perform complete hardware diagnostics on the computer to ensure that the hardware is fully functional.
  • If any failure code gets displayed for a failed component, then please make a note of it. The computer needs to be serviced as it could have a hardware failure. Please run both extensive tests and component tests. It takes about 2 hours to run.
  • If all the tests pass, then please run virus and spyware scans with very reliable security software to quarantine them or delete them if found.
  • Next thing, I would suggest here is to Run Windows Updates troubleshooter -


    Download and install the troubleshooter from this link.


    Now try to perform a Windows update:


    1) In the search box, type and open Windows Updates. 

    2) Check for updates. 

    3) If the updates are available, click on install and restart the computer.


    If the issue still persists, I would suggest here is to update the Bios, chipset and graphics card drivers on your computer from  HP Support Assistant Updates - 


    1) In the search box, type and open HP Support Assistant. 
    2) Check for updates. 
    3) If the updates are available, click on install and restart the computer. 

  • Later please perform all the prescribed steps from this document for slow performance issues. Please perform only those steps that have not been done yet by you.
  • Also please perform all the prescribed steps from this document HP PCs - Using Task Manager (Windows 10, 😎
  • Please check which process is eating up CPU and computer resources and make a note of it Then follow all the steps mentioned in the document to try and resolve the issue.
  • Please check this Microsoft document for enhancing performance issues and perform the relevant steps.

Hope this helps. Let me know how this goes. I genuinely hope the issue gets resolved without hassles and the unit works great.


To simply say thanks, please click the "Thumbs Up" button to give me a Kudos to appreciate my efforts to help. If this helps, please mark this as “Accepted Solution” as it will help several others with the same issue to get it resolved without hassles.


Take care now and have a splendid week ahead. 🙂
