7 Common Reasons (and Fixes) for Lagging Devices
At Professional Computer Concepts, we know that technology can sometimes feel overwhelming—especially when things aren’t working the way they should. That’s why we’re here to break things down in a way that makes sense, without the technical jargon. We believe that everyone deserves to understand their technology so they can make informed decisions without feeling lost or frustrated.
One of the most common frustrations we hear from our clients? “Why is my computer so slow?”
A sluggish computer can make even the simplest tasks feel like a struggle. But before you assume you need a brand-new device, let’s explore the most common reasons computers slow down and what you can do to fix them—without the stress.
1. Too Many Programs Running at Once
The Problem: If you have multiple applications open at the same time—especially ones that use a lot of memory, like web browsers with dozens of tabs, video conferencing tools, or design software—your computer can get overwhelmed.
The Fix: Close programs you’re not using. Restarting your computer can also help clear out background tasks that may be hogging resources.
2. Not Enough Storage Space
The Problem: Computers need free space to function efficiently. If your hard drive (or solid-state drive) is nearly full, your system may struggle to run smoothly.
The Fix:
- Delete files you no longer need.
- Empty your recycling bin.
- Move large files (like videos or photos) to cloud storage or an external hard drive.
3. Your Computer Needs a Restart
The Problem: Many people leave their computers on for days or even weeks without restarting. Over time, programs and background processes can build up, slowing down performance.
The Fix: Restart your computer at least once a week to clear out unnecessary processes and refresh the system.
4. Too Many Background Programs
The Problem: Some programs start running automatically in the background when you turn on your computer, using up valuable resources.
The Fix:
- On Windows, open Task Manager (Ctrl + Shift + Esc), go to the Startup tab, and disable unnecessary programs from launching at startup.
- On Mac, go to System Settings > Users & Groups > Login Items to remove unnecessary startup apps.
5. Your System or Software Is Outdated
The Problem: Running an outdated operating system or software can slow things down because newer applications are designed for more up-to-date systems.
The Fix:
- Regularly update your operating system (Windows or macOS).
- Check for updates to your programs and web browsers.
6. Malware or Viruses
The Problem: If your computer is suddenly running much slower than usual, malware (harmful software) might be the cause. Some viruses work silently in the background, using up your computer’s processing power.
The Fix:
- Run a full scan using your antivirus software.
- Be cautious about downloading files or clicking on suspicious links.
- If your system is infected, consider getting professional IT support to remove malware safely.

7. Your Computer Is Just Old
The Problem: Computers don’t last forever. If your device is more than 5–7 years old, it might not be able to keep up with modern software and workloads.
The Fix:
- Consider upgrading to a solid-state drive (SSD) if you still use a traditional hard drive.
- Adding more RAM (memory) can also help boost speed.
- If your device is too outdated, replacing it with a newer model might be the best solution.
