  1. Check your Internet connection

    Sometimes a computer runs slowly because of a bad Internet connection. Search for and run Speedtest, a free service to check your Internet speed, and compare it with the speed you're paying for. Make sure your router is working properly, and put it in a central area away from walls and metal objects.

  2. Stop unnecessary programs at startup

    Many programs are made to start automatically when you turn your computer on. Use a tool such as Autoruns or Free Delayer to stop unnecessary programs from hogging system resources.

  3. Delete unused programs

    Go through your files and delete anything you don't use or need. Avoid deleting anything you're unsure of, and be sure to back up all important data.

  4. Run a defragmentation program and a virus scanner

    Use your computer's built-in defragmentation program, or download one online. Run it on all drives to consolidate unused data. Next, run a malware and virus scanner such as Malwarebytes, which is free and effective, and remove anything the scanner finds.
