How to Speed Up a Slow Computer

Difficulty: Easy to Medium

Time needed: 15-30 minutes

What you'll need: Your computer (Windows or Mac)


Step 1: Restart your computer

This sounds basic, but many people just close their laptop lid instead of restarting. Click Start > Power > Restart (Windows) or Apple menu > Restart (Mac). A fresh restart clears temporary files and frees up memory.

Step 2: Close unnecessary startup programs

  • Windows: Press Ctrl + Shift + Esc to open Task Manager. Click the Startup tab. Right-click programs you don't need at startup and select Disable
  • Mac: Go to System Settings > General > Login Items. Remove apps you don't need starting automatically

Step 3: Free up disk space

  • Windows: Open Settings > System > Storage. Click Temporary files and delete what you don't need. Also run Disk Cleanup (search in Start menu)
  • Mac: Click Apple menu > About This Mac > Storage > Manage. Use recommendations to free space. Empty the Trash

Step 4: Check for malware

  • Windows: Open Windows Security (search in Start menu), click Virus & threat protection > Quick scan
  • Mac: While Macs are less prone to viruses, download Malwarebytes (free version) and run a scan

Step 5: Update your operating system

  • Windows: Go to Settings > Windows Update > Check for updates. Install all available updates
  • Mac: Go to System Settings > General > Software Update. Install any available updates

Step 6: Increase virtual memory (Windows) or close memory-heavy apps

  • Windows: Open Task Manager (Ctrl + Shift + Esc), click the Memory column to sort by usage. Close apps using the most memory
  • Mac: Open Activity Monitor (search in Spotlight), click the Memory tab, and quit apps using excessive memory

Step 7: Consider a hardware upgrade

If your computer has a traditional hard drive (HDD), upgrading to a solid-state drive (SSD) is the single biggest speed improvement you can make. Adding more RAM (8GB minimum recommended) also helps significantly.


If that didn't work

If your computer is more than 5-7 years old, it may simply be reaching the end of its useful life for modern software. Consider consulting a local tech shop about whether an upgrade or replacement makes more sense for your situation.

Pro tip

Keep at least 15-20% of your hard drive free at all times. When your storage gets too full, your computer slows down dramatically because it can't create temporary files efficiently.
