Best Way to Fix Slow Computer: 10 Tips to Enhance Performance

Are you tired of dealing with a sluggish computer? Before you consider buying a new one, there are simple steps you can take to improve its performance significantly. In this guide, we’ll walk you through ten easy steps to speed up your Windows 10 computer, ensuring a smoother and more efficient experience.

1. Manage Startup Programs

One of the main reasons your computer might be slow is due to the number of programs that run at startup. These can clog your system’s resources, causing delays. To manage these:

  • Press Windows + R to open the Run dialog.
  • Type “msconfig” and press Enter.
  • Go to the Startup tab and open Task Manager.
  • Here, you’ll see a list of programs that start with your computer. Disable any that are unnecessary. If you’re unsure about a program, it’s best to leave it enabled or do a quick Google search to understand its function.

By reducing the number of programs launching at startup, you can significantly improve your computer’s boot time and overall performance.

2. Disable Unnecessary Services

Services are background programs that can slow down your computer. To streamline these:

  • In the System Configuration window, switch to the Services tab.
  • Check ‘Hide all Microsoft services’ to avoid accidentally disabling essential services.
  • Carefully review the remaining services and uncheck those you don’t need. Avoid disabling services related to your hardware, like graphics cards or processors.

Disabling unnecessary services can free up system resources, allowing your computer to allocate more power to essential tasks, thus enhancing its speed and responsiveness.

3. Keep Windows Updated

Regular updates can improve your computer’s performance and security. However, they can also slow down your system if they’re running in the background. To manage updates:

  • Search for “Check for updates” in the start menu and open the settings.
  • Update your system as needed.
  • To prevent updates from running at inconvenient times, go to Advanced options and pause updates until a specific date, preferably when you’re less likely to need uninterrupted computer use.
  • Furthermore, consider enabling automatic updates during off-hours when you’re not using your computer actively to ensure your system stays up-to-date without interfering with your work.

Keeping your operating system up-to-date not only ensures you have the latest features and security patches but also helps optimize system performance by addressing any bugs or performance issues.

4. Run Antivirus and Malware Scans

Malware and viruses can significantly slow down your computer. Running regular scans can help:

  • Ensure your antivirus is up-to-date and run a full system scan.
  • Consider using additional tools like Malwarebytes for an extra layer of protection against spyware and malware.
  • Schedule periodic scans to run automatically to catch any potential threats before they can impact your system’s performance.

A clean system free from malware and viruses operates more efficiently, allowing your computer to perform tasks faster and more effectively.

5. Clear Temporary Files

Temporary files can accumulate and take up space, slowing down your computer. To clear these:

  • Press Windows + R and type temp, then press Enter. Delete everything in this folder.
  • Repeat the process by typing %temp% in the Run dialog. Again, delete all the files you can.
  • Additionally, consider using Disk Cleanup tool provided by Windows to remove temporary files, system cache, and other unnecessary files taking up space on your hard drive.
  • Regularly clearing temporary files not only improves your system’s performance but also frees up valuable storage space for other essential tasks.

By regularly clearing temporary files, you can prevent them from cluttering your system and bogging down its performance over time.

6. Optimize Power Settings

Adjusting your computer’s power settings can also affect its performance. To optimize power settings:

  • Open Control Panel and navigate to Power Options.
  • Select the High Performance power plan to ensure maximum performance.
  • Customize the power plan settings to your preferences, ensuring that features like sleep mode and screen dimming are optimized for performance rather than energy saving.

Optimizing power settings can help your computer run more efficiently, especially during demanding tasks like gaming or video editing.

7. Upgrade Hardware Components

If your computer is still slow after following the previous steps, consider upgrading hardware components such as:

  • Adding more RAM to increase multitasking capabilities.
  • Upgrading to a solid-state drive (SSD) for faster read/write speeds and quicker boot times.
  • Replacing an older CPU with a newer, faster model for improved processing power.
  • Upgrading your graphics card (GPU) for better gaming performance and faster rendering times.

Hardware upgrades can provide a significant performance boost to your computer, extending its lifespan and usability.

8. Disable Visual Effects

Windows 10 includes various visual effects and animations that can consume system resources and slow down your computer. To disable unnecessary visual effects:

  • Right-click on This PC or My Computer and select Properties.
  • Click on Advanced system settings.
  • Under the Advanced tab, click on Settings under the Performance section.
  • Select the option to adjust for best performance or manually uncheck specific visual effects that you don’t need.

Disabling visual effects can help streamline your computer’s performance, especially on older or lower-spec machines.

9. Update Device Drivers

Outdated or corrupted device drivers can cause performance issues on your computer. To update device drivers:

  • Open Device Manager by right-clicking on the Start button and selecting Device Manager.
  • Expand the categories and right-click on the device you want to update.
  • Select Update driver and follow the on-screen instructions to search for and install the latest driver updates.

Updating device drivers ensures compatibility with the latest software and can improve overall system stability and performance.

10. Perform a Clean Install of Windows

If all else fails and your computer is still slow, performing a clean install of Windows can provide a fresh start and eliminate any underlying software issues. Before proceeding, make sure to back up your important files and data. Then:

  • Create a Windows installation media using the Media Creation Tool from Microsoft’s website.
  • Boot your computer from the installation media and follow the on-screen instructions to reinstall Windows.
  • After the installation is complete, reinstall your programs and restore your files from backup.

A clean install of Windows can help remove bloatware, malware, and other software issues that may be causing your computer to run slowly.


By following these ten steps, you can significantly enhance the performance of your slow Windows 10 computer without spending a dime. From managing startup programs to upgrading hardware components and performing a clean install of Windows, these actions can help optimize your PC’s speed and efficiency, providing you with a smoother and more enjoyable computing experience.
