Upgrading and Repairing PCs

Introduction

Welcome to Upgrading and Repairing PCs, 15th Edition. Since debuting as the first book of its kind on the market in 1988, no book on PC hardware has matched the depth and quality of the information found in this tome. The 15th Edition continues Upgrading and Repairing PCs' role as not only the best-selling book of its type, but also the most comprehensive and complete PC hardware reference available. This book examines PCs in depth, outlines the differences among them, and presents options for configuring each system.

More than just a minor revision, the 15th Edition of Upgrading and Repairing PCs contains hundreds of pages of new, revised, and reworked content. The PC industry is moving faster than ever, and this book is the most accurate, complete, in-depth, and up-to-date book of its kind on the market today.

I wrote this book for people who want to upgrade, repair, maintain, and troubleshoot computers or for those enthusiasts who want to know more about PC hardware. This book covers the full gamut of PC-compatible systems from the oldest 8-bit machines to the latest in high-end 64-bit multi-gigahertz speed PC-based workstations. If you need to know about everything from the original PC to the latest in PC technology on the market today, this book and the accompanying information-packed DVD is definitely for you.

This book covers state-of-the-art hardware and accessories that make the most modern personal computers easier, faster, and more productive to use. Inside these pages you will find in-depth coverage of every PC processor from the original 8088 to the latest Pentium 4, Athlon XP, and Athlon 64.

Upgrading and Repairing PCs also doesn't ignore the less glamorous PC components. Every part of your PC plays a critical role in its stability and performance. Over the course of this book's 1,500+ pages, you'll find out exactly why your motherboard's chipset might just be the most important part of your PC and what can go wrong when you settle for a run-of-the mill power supply that can't get enough juice to that monster processor you just bought. You'll also find in-depth coverage of technologies such as RDRAM, DDR2 SDRAM, graphics, audio cards, AGP, PCI, flat-panel displays, DVD+/-RW drives, SCSI, USB 2.0, FireWire, and high-capacity removable storage—it's all in here—right down to the guts-level analysis of your mouse and keyboard.
