🚀 How to Speed Up a Slow Computer: 7 Quick Fixes That Work
We’ve all been there—you’re trying to get work done or load a webpage, and your computer takes forever. At Cairns IT Support, we often hear: “Why is my computer so slow all of a sudden?”
Whether it’s due to aging hardware or system clutter, there are reliable fixes that can bring your PC back to life.
⚙️ 1. Remove Unnecessary Startup Programs
Many apps run quietly in the background when your PC starts up. These slow down boot time and hog memory.
Fix:
- On Windows: Press
Ctrl + Shift + Esc
→ Go to Startup tab → Disable what you don’t need.
🗑️ 2. Uninstall Unused Applications
Old programs eat up storage and sometimes run background services without you knowing.
Fix:
- Go to Control Panel > Programs > Uninstall a program
- Remove anything you no longer use
đź§ą 3. Clean Up Disk Space
Temporary files, old logs, and browser caches can pile up over time.
Fix:
- Use Disk Cleanup or enable Storage Sense
- Tools like CCleaner can also help clear junk (use with care)
⬆️ 4. Upgrade to an SSD
If you’re still using a traditional hard drive (HDD), upgrading to a Solid State Drive (SSD) can improve speed drastically—often 5x faster boot times.
Bonus: At Cairns IT Support, we offer SSD upgrades and data migration services in Cairns.
🔄 5. Add More RAM
Low memory is one of the biggest causes of lag—especially if you run multiple programs or browser tabs.
Fix:
- Upgrade your RAM (4GB → 8GB or 16GB depending on usage)
đź§Ş 6. Scan for Malware or Adware
Unwanted software can hijack your system resources.
Fix:
- Run a full scan with Windows Defender or Malwarebytes
🧑‍🔧 7. Consider a Fresh Windows Reinstall
If all else fails, a clean reinstall can restore your system to factory-speed levels (after backing up your files!).
