Here's the ideal plain-English reference for computer do-it-yourselfers. Upgrading & Fixing PCs For Dummies, 4th Edition, guides you step-by-step to figuring out what's broken and how to fix it. With these easy-to-follow instructions from computer guru Andy Rathbone, you'll be able to take care of all those nagging problems and install all the hardware you need, whether its more memory for a RAM-hungry machine or a faster modem for surfing the Internet. Master the mysteries of your PC's internal workings without becoming, in Andy's inimitable way with words, a technoweenie. Grab a few basic household tools -- a small Phillips screwdriver, an itty-bitty flathead screwdriver, and a paper clip -- and get ready to save some serious bucks by making the upgrades you need all by yourself. Upgrading & Fixing PCs For Dummies guides you through the troubleshooting process to divine what's wrong with your PC and why it's acting in strange and inexplicable ways, and then this book gives you instructions for fixing whatever ails your computer. Don't just give up on your PC and buy a Mac -- get this great all-in-one guide instead and make your PC work the way that it should!

Loaded with solid advice in the fun style typical of this series, Upgrading & Fixing PCs for Dummies is an excellent introduction to what makes your computer go. If you're sure you can put your new modem or video card in by yourself (and you can), this book will provide you with the help you need.

Rathbone starts with an introduction to all the mysterious connections on the back of your computer's case, teaching you how to distinguish a game port from a serial port and an audio jack from a network connection. He then moves inside the case, using drawings and diagrams to illustrate processors, peripheral cards, memory modules, and other internal components. Troubleshooting occupies much of this book, and the author explains the basic "identify and isolate" strategy very well. He also points out what to look and listen for, describing, for example, the meaning of the beeps you hear when you turn your computer on.
