How to become a computer hardware expert/technician?

Most schools have a PC "Hardware/Software" Maintenance class that will cover the basics without getting too complicated, and then you can look for any book that covers A+ certification material. That is where I would start.

I would go with what KBrady suggested.

But, you might want some building blocks to start with, so why not try doing a practice test to assess your knowledge. Since it is only a practice you can look up the questions and read materials about it. This may prove a better way to learn as your doing it at your own pace.

Check out this, CompTIA A+ Core Hardware Certification Practice Questions for a quick test if you want to.

I need a book.

Then ... you need to go back and reread post #2 where the poster said:

you can look for any book that covers A+ certification material

You can also look for a book that has a title similar to "How to Repair PCs"

it's clear that what they said and also what title I should search for. I need a book doesn't mean that I don't know what title I should search for. I need a book that is most popular on that topic. I need one that other hardware experts have read that and when suggesting to others, they directly point to that.

Aye the reason that we were pointing towards this source or Comptia A+ is because it really does provide the basics in terms of computer hardware.

No matter what book you choose, website you use, Hardware is hardware. The suggested company is just recognised for learning users as being the simplest.

But the book you are looking for is CompTIA A+ Certification All-in-One Exam Guide, 8th Edition Exams 220-801 & 220-802: Amazon.co.uk: Michael Meyers: Books. It incorporates practically everything.

But as Mark said, you can look for anything that describes hardware. The reason we cannot tell you a definitive source, is because there isn't one. We can only suggest materials that can help you in your goal. Such as looking at hardware manufacturers websites and learning from them.

The reason I suggested the class is in IT, you should never stop learning. There are plenty of places that will pay for a class or two, for a local community college, if it would be beneficial. Or, you could find out what book they use and just order it. Other than that, you can look at the "Exam Cram" series of CompTIA A+ certification books.

Good luck
