This manual will teach you the essential skills you need to know to becoming an expert with your PC. You will never have to be confused again when the salesperson tells you why you need to buy a particular PC model. You will be able to ask intelligent questions and stop deceiving salespeople from over-charging you. This guide explains the information you need to know, in a step-by-step manner. Always try to grasp a particular concept before moving on to the next. If you take time to go through this guide and actually carry out what you have learned, you will become your own computer expert in 7 days or less. However, this is not a complete guide that will teach you everything you want to know about computers. That would take thousands of pages. But it is enough for an average user to make a decision on what type of PC he needs to buy and to troubleshoot basic problems when they occur. One of the main objectives of this book is to give you enough knowledge so that you can tell the technicians fixing your PC that you are not a complete newbie. You can challenge their decisions and also give your own suggestions. By showing that you too have knowledge with PCs, you will stop the dishonest salesperson from charging you ridiculous prices.
