Hello, I'm 14 and want to learn more about the workings of computers and how to fix computers. I also want to have an A+ certification so that someone may trust me a bit more with fixing their computer. I have built my own gaming rig and know the different parts of a computer, but other than that I don't understand how it all works. I can't afford classes to learn how to do this but I would like a book(s) to give me the basics of repairing computers. Any input is appreciated, and have a nice day
