However, before we go on the “fixing” part, we need to know what causes our computers to perform slowly. Knowing the causes will lead us to the appropriate ways in handling the issues. 

What Causes the Computer to Slow Down? 

Corrupted software and hard drive are the two main reasons why your PC produces a slow response. The other two causes are lack of RAM and hard disk space. If your system lacks enough RAM, your hard drive will try to compensate for it. Thus, slowing down your computer’s performance.

Ways on How to Fix a Slow Computer

Now that we know what triggers a slow computer, let us now address the issue. Below are the ways that can help you on how to fix a slow computer. 


If for instance your PC starts to run slow, restarting it can speed it back up once more. Whenever you are having issues, rebooting will help refresh your computer’s operating system. So, if you never reboot your computer, it will not have any updates. Or worse, it might get viruses that can corrupt your files. So, as much as possible, reboot your computer to improve its performance. 

Uninstall Unused Applications

Do you have applications that you have used before but do not need anymore? If your answer is “Yes”, uninstall them now if you want to experience a speedy computer performance. 

Uninstalling unnecessary programs or applications can give more space on your computer’s storage.  You can rather reserve that space for more important apps or files. Aside from that, it can also enhance your computer’s performance. That’s because the unwanted apps can no longer access your system. 

To know what applications are running on your computer, go to the Control Panel in your windows. Then click on Programs. After that, click on Features where you can see the list of applications. Lastly, choose the application that you want to uninstall.

Delete Temporary Files

There are advantages when deleting temporary documents. Caches, cookies, and internet history are some of the temporary files that you can delete from your computer. Deleting them will give your computer more storage for other applications and files. Also, it can improve your computer’s performance. 

The second advantage is to protect your privacy by deleting internet histories. Get rid of all important data such as email usernames, financial details, passwords, private sites, and more. To delete less important documents, open your temporary folder. Click anywhere inside the folder, then press Ctrl+A. After that, a text box will appear. Press the Delete key and all the unnecessary files will be erased. 

Run Fewer Applications or Programs at the Same Time

The operating system of computers keeps every application and program organized. It enables various programs to run simultaneously without any trouble. However, if you find out that your computer is performing slowly, check if you have too many open tabs. Each window or tab uses up your computer’s memory, thus slowing down your computer.

Close some tabs that you are not using for that time being. As much as possible, open only the most important tabs. The lesser the open tabs, the better assurance you get for an optimum computer performance. When using antivirus, install only one and the best application. Installing more than one can affect the performance of your computer.  

Clean Up Hard Disk and Disk Error

Disk cleanup is a maintenance utility that searches your PC’s hard drive for records that you no longer need. It includes temporary documents, reserved pages, and deleted files that end up in the Recycle Bin. Even if you remove those records, they can pile up after some time and can take a great space on your hard disk. 

This program measures the extra space that can be used by the apps on your hard drive. Choose which files you want to erase and once erased, some space from your hard disk will be recovered. In Windows 10, you can find it at the Startup Menu. Tap the circle cleanup button once you arrive at the Administrative Tools.

Aside from that, Windows has the Quick Clean feature. This allows you to clean the temporary junk documents rapidly. It also cleans extra junk documents, which the Disk Cleanup Utility doesn’t. 

Control Start-up Programs

Nowadays, many programs can run automatically once you turn on your PC. However, some unnecessary programs can slow down your computer’s performance. So, before you set up your Start-up programs, take note of those applications that you need. You may leave antivirus software on Start-up since this is vital for your computer. But learn to disregard those programs that are not necessary. If you fail to disable those unnecessary programs, they will only slow down your system.

Scan for Viruses and Malware

Malware refers to a malicious software, which includes worm, virus, and trojan. With virus, it has the capacity to infuse its code into your computer. It will then replicate and spread itself to different systems forcing programs to perform malicious tasks. Some signs of the virus include corrupted documents, system crashes, and slow system performance. Viruses can enter your computer by downloading files from restricted websites and via email attachments. 

Without the aid of antivirus and repair tools, eliminating viruses and malware can be difficult. Some viruses and undesirable programs reinstall themselves after they are eliminated. You can remove all those unwanted programs by refreshing the PC and by updating the computer system.
