Welcome to the class. If you're interested in learning more about your PC and finding out how to fix some of the most common problems related to both hardware and software, namely Windows XP, you're in the right place.

How this class works

This class consists of four lessons; each has an assignment and a quiz. Read a lesson, complete its assignment (if you want to -- they aren't graded), and then test your knowledge by taking the quiz. Doing the assignments and taking the quizzes will help solidify the knowledge you gain from the lessons.

Many people find that the most helpful part of an HP class is the message board. Here, you can communicate with your fellow students about their experiences in PC troubleshooting. Having a problem with your PC and not sure how to proceed? Ask your classmates for their feedback.

Who should take this class?

This class is for people who already have basic knowledge of computers and Microsoft Windows XP from a user standpoint but would like to learn more. Perhaps you have a specific problem you're trying to solve with your PC, or perhaps you're just curious. Either way, welcome.

If you're not sure whether you're ready for this class, stick around -- at least for Lesson 1 -- and give it a try. You'll find that there's a wide range of experience levels among your fellow students, ranging from brave beginners to people who fix computers for a living. Be patient and helpful with one another, and don't forget that everyone has something to teach and something to learn.

What this class covers

This class covers the basic principles of PC troubleshooting, focusing on the Microsoft Windows XP operating system. Rather than just taking potshots at specific problems, this class focuses on helping you develop a core set of tools and techniques that will help you in any troubleshooting situation.

This first lesson introduces some of the essential tools and concepts for PC troubleshooting. You'll learn about the relationship between hardware, the BIOS, and the operating system; find out which hardware tools you need to work on a PC; and explore some alternative boot modes and software troubleshooting tools.

Although most of this class is specific to Windows XP, it sometimes mentions other Windows operating system options that may be helpful in case you have an older version.

In upcoming lessons, you'll build on these principles by focusing on troubleshooting specific problems with Windows XP and with various pieces of hardware.
