I just finished reading this book. I must say, that as a PC tech , this book is one of the best I've come across. Carey has made it easy for the casual user to understand how to take care of their own computer and fix simple problems. It's written in simple to understand language that anyone can follow. This book is also a valuable reference for even experienced technicians.I will be recommending this book as a must have for all of my customers. Thanks to Carey for bringing a book like this to the masses.
