Why PCs slow down over time

  • Startup apps, background services, and software updates can reduce performance over time.
  • Dust buildup, storage limits, and outdated drivers add to the slowdown.

Quick fixes

  • Restart your computer to clear temporary processes.
  • Close unnecessary programs and browser tabs.
  • Check startup programs and disable the ones you do not need.

Intermediate fixes

  • Run Disk Cleanup and remove temporary files.
  • Uninstall unused programs and toolbars.
  • Scan for malware using Windows Defender or trusted tools.

Advanced fixes

  • Add more RAM if your device struggles with multiple apps.
  • Upgrade to an SSD for faster boot times.
  • Reinstall Windows to refresh performance when needed.

When to call a professional

  • If performance is still slow after these steps, a deeper diagnostic is needed.
  • Hardware issues or failing drives can mimic software problems.
