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

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.
