So, why is your computer so slow?

Several factors will contribute to a slow computer. Some of the most common reasons include


  1. Outdated hardware - If your computer is several years old, it may need more capacity to run newer software or handle larger files.

  2. Software issues - If your software is outdated or corrupted, it can cause your computer to run slow. 

  3. Malware and viruses - These can significantly slow down your computer's performance and even access sensitive information.

  4. System clutter - When your computer's hard drive is full, it can slow down performance. 

  5. Running too many programs at once - If you are running too many programs at the same time, it can significantly slow down your computer.


Understanding what's causing your computer to slow down is the first step in addressing the issue and improving its speed.



How to speed up a slow computer

If you think your computer is running slower than usual, it's time to investigate and fix the problem.


If you are using a business computer

Ask your line manager before you take any action that may be against your company's acceptable use policy. Your IT guy or service providers can handle everything for you.


If you are on a personal computer

Here's what to do if you are looking at a personal computer you do not use for work under a BYOD policy.


1. Check for Malware and viruses

Malware and viruses can seriously harm your computer, compromising your personal information and damaging your system. Regular Malware and virus scans are crucial to protect your computer from these potential threats. 


Several software options are available on the market to complete a thorough scan. Some popular choices include Malwarebytes, Norton Security, and McAfee. These programs offer comprehensive and reliable scans to search your computer and detect and remove any threats that may be present.


If a scan detects anything, it is essential to take immediate action to remove them. Most antivirus software programs can quarantine or delete the infected files. It is recommended that you choose the option to delete the infected files to remove the threat from your system altogether.


2 Clear unnecessary programs and files 

Your computer may run slower than usual because it has accumulated too many unused programs and unnecessary files. These programs and files occupy valuable storage space, decreasing your computer's performance. 


It's important to regularly clear out unused programs and files to fix this issue. Here's a step-by-step guide on how to do so:


3. Uninstall unused programs

  • Go to the Control Panel on your computer settings 

  • Click on "Programs and Features" 

  • Scroll through the list of installed programs, check which you use regularly, and identify any that you no longer need 

  • Click on a program you no longer need and select "Uninstall" 

  • Follow the screen prompts to complete the uninstallation process 


4. Delete unnecessary files

  • Go to your files folder 

  • Identify any files that you no longer need (such as old documents, pictures, or videos) 

  • Select the file and press "delete" 

  • If you're unsure about deleting a file, you can always transfer it to an external hard drive or cloud storage instead 


5. Update your operating system and drivers 

Outdated software can cause crashes, slow performance, and leave your computer vulnerable to cyber threats, so you should avoid it. Updating your device regularly is vital.

To update your operating system, go to your settings and click the "Update and Security" option. From there, you can check for system updates and choose to install them.


Updating your drivers and ensuring that your hardware components function correctly is also essential. To update your drivers, go to your device manager and select the device you wish to update. Then, right-click and select "Update driver." Alternatively, some hardware manufacturers offer software that automatically updates drivers, which can be a convenient option.


6. Disable unnecessary startup programs

Many programs will automatically start running in the background as you turn on your computer. This can slow down your boot time and consume system resources. To disable these startup programs, go to the Task Manager or System Configuration tool and disable the programs you don't need to open on start-up.



The benefit of reducing computer lag

Remember, a fast and efficient computer system saves time and enhances productivity and overall experience. So, incorporate the tips we have given you into your routine to keep your computer system healthy and running smoothly.
