Over time, computers can slow down due to cluttered files, outdated software, and unnecessary background processes. If your system is lagging, taking forever to start up, or struggling with basic tasks, it’s time to give it a proper clean-up!

If you find yourself asking ‘why is my computer so slow?’ then look no further! By following our ten top tips, you can improve its efficiency and longevity. Let’s explore how to speed up your computer and optimise its performance!

1. Remove unnecessary programs and files

One of the quickest ways to speed up your computer is by uninstalling programs you no longer use. Unused applications take up valuable storage and may even run background processes that slow down your system.

How to uninstall unused programs:

On Windows, go to Control Panel > Programs > Uninstall a program.
On macOS, drag unwanted applications to the Trash and empty it.

Also, you may want to consider removing old files, especially large ones like videos and downloads, that you no longer need. Organising your files into folders can also make navigation easier and improve your workflow!

2. Clear temporary files and cache

Web browsers and software accumulate temporary files and cached data over time. While these help speed up your access to things you need frequently, they could also be the reason your computer is so slow if you don’t clear them every now and then.

Steps to clear temporary files:

On Windows, use Disk Cleanup (search for it in the Start menu) to remove temporary files.
On macOS, use Finder > Go > Go to Folder and type ~/Library/Caches to manually delete cache files.
For browsers, go to settings and clear cookies and cache.

3. Manage startup programs

Many applications automatically start when your computer boots up. This can be handy, but it also significantly slows down your computer. Which is especially annoying if they’re not even apps you immediately need! You may want to consider disabling these unnecessary startup programs to speed up your computer.

How to disable startup programs:

On Windows, open Task Manager (Ctrl + Shift + Esc), go to the Startup tab, and disable unwanted programs.
On macOS, go to System Settings > Users & Groups > Login Items and remove unnecessary apps.

This simple tweak can noticeably speed up your computer’s boot time.

4. Update software and drivers

Outdated software can also lead to a slow computer, as well as security vulnerabilities and crashes. You should update your system on a regular basis to keep it running efficiently and protect it from malware threats.

Updating your system:

Check for OS updates (Windows Update or macOS Software Update).
Update drivers (especially for graphics, network, and peripherals) via the manufacturer’s website or Windows Update.
Keep essential applications updated to avoid compatibility issues.

5. Run a Malware Scan

Malware and viruses can significantly slow down your computer, steal data, and cause crashes. Regular security scans help detect and remove these threats.

How to Scan for Malware:

Use Windows Defender (built-in for Windows) or third-party antivirus software.
On macOS, use trusted security tools like Malwarebytes.
Avoid downloading software from untrusted sources to prevent infections.

A secure system is a fast and efficient one, making this an essential step in computer maintenance tips.

6. Defragment and optimise your hard drive

If you’re using an older computer with a traditional hard disk drive (HDD), fragmentation can slow down file access times. Running a defragmentation tool can help speed things up.

How to defragment:

On Windows, search for Defragment and Optimise Drives and follow the prompts.
macOS does not require manual defragmentation, as it optimises itself automatically.

Top tip: If you have a solid-state drive (SSD), ensure the Trim function is enabled for better performance.

7. Free up disk space

A full hard drive can slow down your system. Did you know that keeping at least 20% of your storage free helps maintain smooth operations?

Ways to free up space:

Use Storage Sense (Windows) or Optimise Storage (macOS) to remove old system files.
Move large files to an external hard drive or cloud storage.
Delete duplicate files using specialised software.

8. Clean your hardware

We don’t want to see any dust bunnies in your computer’s machinery! Dust and debris can cause overheating, leading to reduced performance and potential hardware damage.

Cleaning tips:

Use compressed air to remove dust from vents, fans, and keyboards.
Wipe screens and surfaces with a microfiber cloth and appropriate cleaner.
Ensure proper ventilation by keeping your computer on a hard, flat surface.

Remember that physical maintenance is just as important as digital clean-up.

9. Upgrade your hardware

If your computer is still slow after all these optimisations, upgrading your hardware might be the best solution.

Best upgrades for performance:

Increase RAM: More memory allows for better multitasking.
Switch to an SSD: SSDs are significantly faster than traditional HDDs.
Upgrade CPU or GPU: If you perform intensive tasks like gaming or video editing, upgrading these components can make a major difference.

Even small hardware upgrades can help speed up your computer!

10. Restart your computer regularly

Ah, yes. The oldest trick in the book. But still, many people leave their computers running for days or weeks. This can lead to a slow computer due to accumulated background processes. Restarting your computer clears RAM, closes unnecessary processes, and installs updates. And it’s not the same as shutting it down!

How often should you restart?

Ideally, restart your computer at least once a week.
If you experience slow performance, try restarting before troubleshooting further.

And your computer should be a little faster now!

Whether it’s decluttering files, managing startup programs, updating software, or upgrading hardware, taking the time to look after your machine will make a significant difference in its performance. Plus, it will extend the life of your device, making daily tasks more enjoyable and hassle-free.
