HP PCs - Computer Is Slow (Windows 10)

This document is for HP computers with Windows 10.
Go to the HP Guided Troubleshooting Solution to resolve problems related to your computer's performance, OR follow the steps below.
Perform regular maintenance to enhance the performance of your computer. Use the information in this document to control when applications run, adjust how your computer uses memory resources, and reduce heat inside your computer.
  note:
HP SmartFriend is a support service that can help you troubleshoot slow performance and improve the speed of your computer (only available in the United States and Canada). For more information, see HP SmartFriend (in English).
  note:
4GB RAM or more is recommended for best performance in Windows 10. Some computers might not be upgradeable (sealed) and will run poorly with the latest operating systems. For step-by-step instructions on upgrading RAM, see HP Notebook PCs - Upgrading Memory (RAM) or HP Desktop PCs - Upgrading Memory (RAM).
Try this first
Before completing the troubleshooting procedures in this document, try the following steps:
  • Make sure there is at least 15% free space on the hard drive. For information about freeing up more space, see the Free space on the hard drive section of this document.
  • Update the BIOS. Refer to the HP support document HP Notebook PCs - Updating the BIOS or HP Desktop PCs - Updating the BIOS. If there is no BIOS listed for your version of Windows, choose the latest version of Windows from the drop-down menu and install that BIOS.
  • Update the graphics driver using Device Manager:
    1. In Windows, search for and open Device Manager.
    2. In the list of devices, expand Display adapters.
    3. Right-click the graphics device and select Update Driver Software.
    4. Click Search automatically for updated driver software.
    5. Follow the onscreen instructions to install the updated driver.
    6. Restart your computer to complete the installation of the updates.
Regularly maintain your computer using tools and updates
HP recommends maintaining your computer on the following schedule:
Weekly: Update virus definitions and perform a virus scan.
Monthly: Perform maintenance tasks using HP Support Assistant or by performing the individual cleanup tasks as described in this document.
Quarterly: Check for dust buildup, and clean as necessary to keep your computer from overheating due to dust buildup.
Check for corrupted Windows system files
Corrupt Windows system files can slow down the computer and cause other problems. System File Checker (SFC) is a utility in Windows that scans for corrupted system files. If SFC finds a problem, it tries to replace the problem files from a cached version on your computer.
If System File Checker cannot replace the corrupt files, use the Deployment Image Service and Management Tool (DISM). DISM checks the corrupted files, then downloads and replaces the files through Windows Update.
Use the following instructions to run System File Checker.
  1. In Windows, search for Command Prompt. In the search results, right-click Command Prompt and select Run as administrator. Then click Yes.
  2. In Command Prompt, type sfc /scannow. Make sure to include the space between sfc and the /.
    Press Enter and wait while System File Checker scans for corrupted files.

    Running System File Checker
  3. When scanning is complete, the results are displayed on the screen.
    • If the file checker found and replaced any corrupted files, restart the computer and check the performance.
    • If the file checker did not find any corrupted files or found corrupted files but could not replace them, go to the next step.
  4. If System File Checker finds corrupted files but cannot replace them, use the Deployment Image Servicing and Management (DISM) tool. DISM checks the corrupted files; then downloads and replaces the files using Windows Update.
    In Windows, open a web browser.
      note:
    You need to be connected to the Internet to use DISM.
  5. In Windows, search for Command Prompt. In the search results, right-click Command Prompt and select Run as administrator. Then click Yes.
  6. In Command Prompt, type dism.exe /Online /Cleanup-image /Restorehealth. Make sure to include the space before each / in the command line.
    Press Enter and wait while DISM works. This might take several minutes.

  7. If DISM finds corrupted files, it replaces them using Windows Update. If this occurs, after DISM is finished, restart your computer and see if the performance has improved.
Manage applications and system features to increase performance
Computer performance is affected by some system feature settings, and also when too many apps are running at one time. This section describes different ways to manage how and when applications and features run on your computer.
Being connected to the Internet, watching TV or a video, playing games, listening to music, and running virus scans are all software tasks that can use a lot of system resources. Running more than one of these tasks can add up and cause the system to slow down. Run virus scans and other system tools when the computer is not in use.
Change how your computer uses memory
Manage how your computer uses memory to help resolve slow performance issues. Use the steps in these sections to adjust virtual and hard disk memory.
Reduce heat inside the computer to prevent overheating
Heat buildup can cause problems for any computer. Generally, when temperatures inside the case rise above 35 degrees Celsius (95 degrees Fahrenheit), the risk of damaging important internal components increases greatly.
The most common cause of overheating is the accumulation of dust inside the computer. Electrical components in a computer generate heat, and fans inside the computer help move the air to keep the components cooled to normal operating temperatures. Inadequate cooling causes excess heat to build up inside the case which can damage components. The sound of the fan running constantly might indicate the computer is not running as efficiently as possible, and/or accumulated dust is clogging the air vents.
Upgrade memory
Upgrading memory can improve system performance. You can upgrade random-access memory (RAM) on most HP and Compaq computers. Refer to the manual of your computer model to find out if your RAM can be upgraded. For step-by-step instructions on upgrading RAM, see HP Notebook PCs - Upgrading Memory (RAM) or HP Desktop PCs - Upgrading Memory (RAM).
Adjust or turn off OneDrive Sync
In some newer versions of Windows 10, by default, the files are automatically saved to OneDrive (in the cloud). If OneDrive syncing is enabled, files are saved to both your OneDrive account and to your computer. This permits you to access your files from any device connected to the Internet. To achieve this, OneDrive syncs files between your computer and OneDrive so both copies are always up to date. However, your computer can slow down while OneDrive is syncing your files.
You can stop OneDrive from syncing files and see if that speeds up your computer.
  caution:
When you stop syncing, your files and folders stay on OneDrive but they are not saved to your computer. If the files are already saved to both OneDrive and the computer, the files on the computer will be deleted. If you need to access files when you don't have an Internet connection, you might want to choose a different method, or change the default save location to your hard drive instead of OneDrive.
Use the following steps to stop syncing OneDrive.
  1. In Windows, search for and open File Explorer.
  2. Right-click OneDrive, then select Choose OneDrive folders to sync.

  3. Remove the check from Sync all files and folders in OneDrive, then click OK.

  4. Click OK to stop syncing.
      caution:
    When you stop syncing, your files and folders stay on OneDrive but they are not saved to your computer. If the files are already saved to both OneDrive and the computer, the files on the computer will be deleted.

  5. Restart your computer to see if the performance has improved.
  6. If your computer still runs slowly and performance has not improved, turn OneDrive syncing back on. Select the check box to Sync all files and folders, or select specific files and folders to sync.

Reset the PC
Resetting your computer reinstalls Windows 10 and removes all your personal files. Resetting your PC should be one of the last things you should try.
If you want to keep your personal files during the reset process, back them up first and then restore them when the reset is complete.
Perform an HP System Recovery
If the above steps did not improve the slow system performance issues on your computer, reinstall the operating system to factory settings. See HP Guided Solution - Performing an HP System Recovery for instructions.
