Is your PC running slow and making even simple tasks feel frustrating? You’re not alone. Over time, computers can lose their speed due to cluttered files, unnecessary programs, or outdated software. The good news is that you don’t need to be a tech expert to improve computer speed. In this guide, we’ll show you 5 easy steps for a slow computer fix, so you can get your machine back up to speed quickly.
1. Uninstall Unnecessary Programs
One of the most common reasons your computer slows down is too many programs running in the background. These applications use valuable memory and processing power even if you’re not actively using them.
How to do it:
- On Windows, go to Control Panel > Programs > Programs and Features.
- Browse the list and uninstall any programs you don’t need.
- Be cautious not to remove system-critical software—stick to games, trial programs, and old utilities you recognize.

Tip: After uninstalling, restart your PC to ensure all changes take effect.
2. Disable Startup Application
Too many startup programs can bog down your computer when you log in. Disabling these apps will help you improve computer speed dramatically.
How to do it:
- Press Ctrl + Shift + Esc to open Task Manager.
- Click the Startup tab.
- Review the list of applications set to launch at startup.
- Right-click and Disable the ones you don’t need running automatically.
Tip: Keep essential utilities like antivirus enabled, but disable tools like chat apps or updaters you don’t use often.
3. Clean Up Disk Space
Low disk space slows down your PC’s ability to read and write data. Freeing up space is an easy slow computer fix.
How to do it:
- Use Windows built-in Disk Cleanup tool:
- Search “Disk Cleanup” in the Start Menu.
- Select the drive you want to clean.
- Check files you’d like to delete (e.g., Temporary Files, Recycle Bin).
- Click OK and confirm deletion.
Tip: Consider moving photos and videos to an external drive or cloud storage to save more space.
4. Check for Malware and Viruses
Malware not only compromises security but can also make your PC painfully slow.
How to do it:
- Run a full system scan using your antivirus software.
- If you don’t have antivirus, download free tools like Malwarebytes.
- Quarantine or remove any threats found.
Tip: Keep your antivirus updated to prevent future infections.
5. Update Your Operating System and Drivers
Outdated software and drivers can cause compatibility issues and poor performance.
How to do it:
- For Windows:
- Open Settings > Update & Security > Windows Update.
- Click Check for updates and install everything available.
- Update hardware drivers through Device Manager:
- Right-click devices (like Display Adapter or Network Adapter) and choose Update driver.
Tip: Regular updates ensure you have the latest performance improvements and security patches.
