Computer running slow (causes, troubleshooting, fixes, desktop, laptop)

Desktop computer or laptop running slow? What are the reasons behind it and how to fix it?

When we buy a new computer it's as fast as a lightning bolt. However, as time goes by, computers tend to become slower and slower. There are many reasons why a computer can become slower, among which the most common are:

  • Corrupt cache and data files;
  • Too many processes running in the background;
  • Lack of free memory;
  • Viruses and malicious software;
  • Too many programs starting automatically when you turn on the computer;
  • Disk fragmentation (not applicable if you use an SSD);
  • Age of the computer.

The solutions listed below work on any laptop (Dell, Asus, Acer, HP, Msi, MacBook, iMac, Mac) on any operating system (Windows, Mac OS, and Ubuntu). They will help you speed up your computer, and improve its performance. All you need to do is to follow them to the detail.
