Learn How to Repair Computers: Get Certified in 7 weeks


Have you ever wished you knew enough about computers to repair them? Are you tired of hearing about other people making $50 to $200 an hour as a computer technician, perhaps with their own business? Would you like to have a piece of the pie to? Well now, you can.

You will learn what makes a computer tick, what each part does, how it all fits together. Want to know how hard drives work? Want to know what is inside a CPU? Want to know what is on the motherboard?

Each week different sections of the computer will be covered along with how each section works and why it works. One other piece of information that is vital to know - every lesson will also cover A+ certification so it will be imperative you pay attention to each word in each lesson. There will also be an actual sample test at the end of the computer repair course.

This comprehensive course provides an introduction to the fundamentals of installing and maintaining microcomputers. Topics include: identifying components and their functions, safety, installation procedures, troubleshooting techniques, and preventive maintenance. This course in computer repair is up-to-date and will provide you with the necessary knowledge necessary to prepare for the A+ Certification Exam.

The required book is:

"I gained more knowledge knowing the Fundamentals of a computer. Having being in the field for nearly 10 years. I feel more confident knowing what I learned in this class." - Claude Rymer

"After taking this course, I now realize that there were several computer terms, that I recognized, but did not know the true definition of, therefore I am very fortunate, to have taken this course to better pursue my interest in repairing computers. This course, was so easy and understandable, I would recommend it to anyone who would be interested in computer repair." - Carolyn Willoughby

"I had little to no experiance in this field before I started this class. Greatly improved my knowledge." - James Smith

"I learned more in depth information about computer systems and how they work. This course met my expectations very well." - Tabitha Chedore


This course is also known as Microcomputer Installation and Maintenance (A+ Certification Prep). When registering you will see this course title. It has been recently been updated for 2009 to be current with today's computer technology and repair techniques.
