Slow computers aren’t just frustrating—they can cost time, productivity, and sanity. Whether you’re preparing an urgent presentation at your Auckland office or trying to catch up on home tasks, a sluggish device can throw your day off course.
At Advanced Computers, our technicians see these issues every day. Based on our experience helping Kiwis get the most from their devices, here are 15 practical ways to boost your computer’s performance.
1. Audit and Remove Unnecessary Software
Many computers come with pre-installed programs you’ll never use. Take a few minutes to uninstall software that isn’t essential. On Windows, go to Settings → Apps; on Mac, drag unused apps to the Trash. Less clutter means faster performance. If you’re unsure which programs are safe to remove, our team can review your computer in Auckland and streamline your system.
2. Disable Startup Programs
Some apps launch automatically when your computer boots, slowing startup times. On Windows, open Task Manager and check the Startup tab; on Mac, check System Preferences → Users & Groups → Login Items.
Disabling unnecessary startup apps keeps your computer snappy without affecting essential software.
3. Defragment Your Hard Drive (HDDs Only)
Older hard drives can fragment files, forcing your computer to work harder. Use the built-in Windows Defragment and Optimise Drives tool or seek guidance if you’re unsure.
Note: Solid-state drives (SSDs) don’t need defragmentation, but cleaning temporary files is still important.
4. Clear Temporary Files and Cache
Cache, cookies, and temporary files slow computers over time. On Windows, use Disk Cleanup or Storage Sense; on Mac, clear system caches via Finder → Go → Go to Folder → ~/Library/Caches.
Regular cleaning improves speed and reduces the risk of system issues.
5. Adjust Power Settings
On Windows, Power Saver mode conserves energy but can reduce performance. Switch to Balanced or High Performance for faster processing. Mac users can check Energy Saver settings to balance speed and battery life.
6. Back Up Files Locally or in the Cloud
A full hard drive slows your computer. Offload files to an external hard drive or cloud storage. Auckland businesses can use local providers for faster syncing, while home users might choose NZ-based cloud options like Spark Cloud or Google Workspace.
7. Simplify Visual Effects
Fancy animations and transparency effects use processing power. On Windows, adjust Visual Effects for best performance. On Mac, reduce motion and transparency in System Preferences → Accessibility → Display.
8. Scan for Malware and Viruses
Even the best antivirus software can miss threats. If your computer is slow, a malware scan can reveal hidden issues. Our Auckland technicians regularly detect malware slowing clients’ computers and can remove it safely without losing data. Check our Virus Removal service to know more.
9. Upgrade RAM
Adding more RAM can significantly improve speed, especially for small office PCs running multiple apps. In Auckland, RAM upgrades are affordable and quick—our team can install compatible modules while you wait. Contact us or visit our branches to get more information.
10. Disable Browser Extensions and Add-Ons
Extensions like toolbars or Flash content can slow browsing. Review and remove anything unnecessary, especially in Chrome, Edge, or Safari.
11. Use Built-In Troubleshooting Tools
Windows and Mac both include diagnostic tools. Running these weekly can identify slowdowns before they become serious problems.
12. Keep Your Computer Well-Ventilated
Overheating affects performance and hardware longevity. Keep laptops off carpets, dust off vents, and consider cooling pads for prolonged use.
13. Reboot Regularly
Restarting your computer clears temporary files, resets processes, and ensures updates take effect. For small offices in Auckland, setting weekly reboot reminders keeps systems running smoothly.
14. Reinstall the Operating System (If Needed)
A clean OS installation can give older computers a fresh start. Our technicians can back up your files and reinstall Windows or macOS efficiently.
15. Know When It’s Time to Upgrade
Sometimes, no amount of tweaking can save an ageing system. If your computer struggles with everyday tasks, upgrading the computer might be the best solution. Our team can advise on models suitable for Auckland homes or small businesses.
