Perform a system cleanup without HP Support Assistant

A computer's hard disk drive can have a major effect on system performance. Over time the hard drive can become cluttered with unwanted or temporary files, the data can become fragmented and stored in an inefficient manner, or there might be disk errors on the drive itself. All these issues can impact system performance, and all are easy to prevent through maintenance. Use this information to maintain hard drive performance through removing unwanted and temporary files, checking the hard drive for errors, and defragmenting the drive.

Empty the Recycle Bin

Empty the Recycle Bin to increase the amount of unused space (free space) on the hard drive.

  1. On the Windows desktop, double-click the Recycle Bin icon .

  2. To restore any mistakenly deleted items, right-click the file(s), and then select Restore.

  3. Click the Manage tab, and then select Empty Recycle Bin.

  4. Select Yes to confirm.

    Windows removes the contents of the Recycle Bin from the hard drive.

Delete temporary files and directories

Delete temporary files and folders to increase hard drive space and reduce the time Windows takes to access the hard drive.

  1. In Windows, search for and open Disk Cleanup.

  2. Select the drive you want to delete the files from, and then click OK.

  3. Wait while Disk Cleanup calculates how much space you can free on the selected drive.

  4. After the analysis completes, select the check box next to the types of files you want Disk Cleanup to delete.

    CAUTION:

    Selecting some options can have a negative effect. For example, selecting Setup Log Files deletes the files that online phone support agents use to help troubleshoot setup problems. Click a file type, such as Temporary Internet Files, to display a description. Do not delete files until you know the files are unnecessary for using your computer.

  5. Click OK, and then click Delete Files when prompted.

Find apps that use excessive system resources

Use Task Manager to find and stop processes or applications using an excessive amount of system resources.

  1. In Windows, search for and open Task Manager.

    Task Manager displays currently-running applications.

  2. Click More Details, and then select a tab for more information.

    • Processes: Displays all the currently-running operations and how much of the system resources are being used by each process. Some processes are necessary and should not be stopped. If you are unsure if a process is necessary, search for details about it on the internet.

    • Performance: Displays a visual representation of the overall system performance. Click Open Resource Monitor for an even more detailed view of individual processes.

    Example of an app using high levels of system resources on the Performance tab
  3. On the Processes tab, if you want to close an app, or if the app is listed as Not Running, click End Task.

Select apps to open when Windows starts

A startup application is software that opens when Windows opens. Over time, as you install more and more apps, the number of startup applications increases. Common apps that load and run in the background are instant messaging apps, multimedia apps, game launchers, and toolbars. You can improve system performance by stopping some of these apps from opening, or by changing their settings.

  1. In Windows, search for and open Task Manager.

  2. Click More details, and then select the Startup tab.

  3. Select any startup items that do not contribute to the system and are unwanted, then click Disable.

    CAUTION:

    Disable only those startup items that are known and unwanted.

    Selecting an app to disable at startup
  4. Restart the computer.

  5. If Windows or other software stops working after you disable a startup item, reverse these steps to enable the item.

Turn off non-essential graphical features

  1. In Windows, search for and open Adjust the appearance and performance of Windows.

  2. On the Performance Options window, select Adjust for best performance, and then click OK.

    Selecting Adjust for best performance to turn off non-essential graphical elements
    Windows turns off all visual effects, such as animation of the taskbar and windows elements, displaying shadows under windows, displaying window contents while dragging, etc.

Change how your computer uses memory

Help resolve slow performance issues by adjusting virtual and hard disk memory.

Free up space on the hard drive

Increase the amount of unused space (free space) on the hard drive to prevent low disk space errors and improve system performance.

  1. In Windows, search for and open Storage settings.

  2. View how much space is available on the hard drive (C: drive is the most common).

    For best performance, the drive should have at least 15% free space. If the hard disk drive has less than 15% free space, continue with these steps
  3. Under the C: drive, select each category to determine where you can free up the most space. The most common categories where you can free up space are Apps & games, Temporary files, Documents, and Pictures.

    CAUTION:

    RECOVERY (D:) or FACTORY_IMAGE (D:) hard drives are reserved for system recovery and removing files from these drives can damage your computer.

    Reviewing the storage being used by the computer hard drive
  4. Move any files you want to keep to a USB drive or external hard drive to help free up space. This is highly recommended for larger files not needed for daily use, such as pictures and videos.

  5. Remove any unwanted files and applications, and then restart the computer.

Prevent memory allocation problems

Isolate apps or processes that are no longer in use that might be using unnecessary memory resources.

Memory is allocated to processes in device drivers and applications during normal use. The allocated memory is made available again when the process is no longer running. However, sometimes memory remains allocated. This is known as a memory leak. On rare occasions, an incompatible app might continue to allocate memory while it is running, causing the system to slow down and eventually lock up.

  1. Close all open software applications or programs, making sure to allow apps time to fully open before closing them.

    HP recommends waiting five seconds after an app opens before you close it, even if the app was opened unintentionally.

  2. Restart the computer.

  3. In Windows, search for and open Task Manager.

  4. Click More details, select the Performance tab, and then select Memory.

  5. Click Open Resource Monitor to view how your computer uses memory.

    If a window displays prompting you for an administrator password or confirmation, type the requested credentials.

    Opening Resource Monitor
  6. On the Overview tab, open the Memory section, and then scroll down the list to view which apps are using memory.

  7. Open an app suspected of causing the computer to run slowly, review the percentage of Used Physical Memory, and then write down the information.

  8. Close and reopen a suspected app repeatedly, and then check the percentage of Used Physical Memory, comparing this number to the one recorded. Each time, wait about 10 seconds before opening the app again.

    • If the Used Physical Memory percentage returns to the same numbers or similar each time, the suspected app is probably not creating a memory leak.

    • If the percentage of Used Physical Memory continues to increase, there is a memory leak. Contact the software manufacturer for available patches or fixes.

Use ReadyBoost

Use ReadyBoost with a removable drive to improve system performance without adding more RAM to the computer.

  1. Make sure you have a removable drive, such as a USB flash drive, with a high data transfer rate and at least 500 MB of free space.

  2. Insert the removable drive into the appropriate port on the computer.

  3. In Windows, search for and open File Explorer.

  4. In File Explorer, right-click the removable drive, and then select Properties.

  5. On the Properties window, select the ReadyBoost tab, and then selectReadyBoost.

  6. Move the slider to the set the space to reserve for system speed, reserving at least 9048 MB for optimal performance.

  7. Click OK to reserve the space on the removable drive for ReadyBoost and save the settings.

    On the removable drive, the space reserved for ReadyBoost is saved in a file named ReadyBoost.sfcache.

Change the paging file size

The paging file is an area on your hard drive that Windows uses like memory. Increasing the paging file size can help speed up the computer and improve performance.

  1. In Windows, search for and open Control panel.

  2. In the search field, type System, and then select System from the results.

  8. Close the system windows, and then restart the computer.

Reduce heat inside the computer to prevent overheating

When temperatures inside the computer rise above 35º C (95º F), the risk of damaging important internal components increases.

You might experience the following issues when the computer overheats:

  • After pressing the power button, the computer freezes on a black screen and Windows does not start, or Windows starts but does not respond to input.

  • Basic tasks or applications take more time to complete than usual.

  • Windows does not respond, suddenly restarts, or displays an error message while in use.

  • Games stop responding during play.

  • Fans inside the computer become louder as they start spinning faster to remove excess heat.

  • The mouse and keyboard stop responding.

There are many reasons your computer might be overheating, but the most common reason is dust buildup on the fans, which can trap heat. Reduce the heat inside the computer to prevent any damage to its internal components.

  1. Make sure the computer is in a cool room and placed on a hard, level surface, such as a desk or table with adequate ventilation.

    CAUTION:

    Placing the computer on a cloth surface, such as carpet, your lap, or a couch cushion, can restrict the airflow. Prolonged air restriction causes overheating and potential damage.

  2. Turn off the computer, and then use a vacuum to clean the vents.
