  • downloading something from unknown sites,
  • opening unknown webpages,
  • browsing websites with delicate or adult content,
  • receiving strange emails or opening strange attachments,
  • browsing the contents of an external storage device opened on your computer,
  • or even just surfing the web, without installing or opening anything on your computer

Make Sure You Computer Is not Overheating

Overheating may cause slow computer performance. Turn off your computer and let it cool or lower the temperature. Make sure the cooler works properly and clean dust out of your computer.

Low disk Space

You computer may become slow all of a sudden because of lack of disk space. Did you copy any large files or volumes of information to your hard drive before you computer became slow? If so, try to free some disk space, that can help. For example, copy some data to another hard disk.

How many applications do you have running at once?

Running too may applications at once may slow down you computer because any computer’s resources are limited. Close some applications that you are not using right now. If, in addition, you haven’t restarted it for several days, restart your computer.

We hope how you know what to do if your computer is so slow.
