Simple fixes anyone can try before buying a new machine
A sluggish computer can be one of the most frustrating problems – whether you’re trying to get work done, join a Zoom call, or stream a video. The good news? Most slowdowns don’t require a trip to the repair shop. In many cases, a few quick adjustments can make your machine noticeably faster.
Here are practical, proven tips to help speed up your slow computer, based on both expert advice and real-world troubleshooting.
Disable Unnecessary Startup Programs
When your computer starts, it often loads a list of background programs – some of which you may not even use. These can drain memory and slow everything down.
Here’s how to fix it:
- On Windows, open Task Manager (Ctrl + Shift + Esc) and click the Startup tab. Disable programs you don’t need right away.
- On macOS, go to System Settings > Users & Groups > Login Items.
From there, disable only the programs you recognize and don’t need immediately.
If you’re unsure, it’s best to research the program first or test changes one at a time to ensure nothing essential is affected. Disabling unneeded startup apps reduces boot time and frees up system resources.

Clean Up Your Hard Drive
A cluttered hard drive not only eats up space but can also affect system performance. Temporary files, unused apps, and old downloads build up over time.
Try these steps:
- Run Disk Cleanup (Windows) or Manage Storage (Mac).
- Uninstall programs you no longer use.
- Empty the Recycle Bin or Trash.
Consider using a trusted utility like CCleaner to clear out cached files and browser data safely.
Check for Malware and Viruses
Malware, spyware, and background scripts can significantly slow down your system and even compromise your data.
Run a full system scan using your preferred antivirus. If you don’t have one installed, try a reputable free option like Malwarebytes, which is known for detecting threats missed by traditional antivirus software.
To stay protected long-term:
- Keep your antivirus updated.
- Avoid suspicious downloads or links.
- Use a secure browser with tracking protection.
Free Up RAM (Memory)
If your system is running too many applications at once, it can run out of memory (RAM), causing programs to lag or freeze.
Tips to reduce memory usage:
- Close browser tabs you’re not using.
- Quit heavy apps running in the background (like Photoshop or Zoom).
- Restart your computer periodically to reset memory.
Bonus Tip: If your machine still runs slowly with only a few programs open, it may be time to upgrade your RAM. It’s often one of the most affordable ways to boost performance.
Restart Regularly
You’d be surprised how many users leave their computers running for weeks. A simple restart can clear out memory, stop runaway processes, and refresh system functions.
Make it a habit to reboot your system every few days – especially if you notice lag.
Update Your Operating System and Drivers
Outdated systems and drivers can cause performance problems, security risks, and compatibility issues. Regular updates improve speed, stability, and support for new hardware.
- On Windows, go to Settings > Windows Update
- On Mac, go to System Settings > General > Software Update
Also check for graphics card and motherboard driver updates on the manufacturer’s site.
Should I Buy a New Computer?
A slow computer doesn’t always mean you need to ask, “Should I buy a new computer?” – in many cases, performance issues can be resolved with simple maintenance and smart software choices. If you’ve tried the tips above and your system is still lagging, reach out to a professional for a hardware check or upgrade.
