If your computer is having performance issues, but you don't know which hardware component is causing the problem or how to fix it, Dell offers several hardware diagnostic tools to help you.

Online diagnostic tools

  1. Dell PC Diagnostics. An online application that provides personalized hardware analysis and support.
  2. Dell PC Health Check. An application that uses your internet connection to analyze your computer and offer support.

Offline diagnostic tools

  1. Dell PC Checkup. A diagnostic tool that is part of the Dell Support Center application that comes preinstalled on your computer.
  2. Dell Pre-Boot System Assessment (PSA). A diagnostic tool that is built in to your computer and is accessed before the operating system loads.
