Peter Norton's Guide to Upgrading and Repairing PCs provides expert advice using a friendly, step-by-step approach. Understand how each component of your PC system functions and why earlier models and technologies can often prove to be bottlenecks in your day-to-day work. Learn about the new technologies, such as MMX-equipped Pentium IIs, DVD, USB, and FireWire, and determine whether each spells death or renewal for your aging PC and existing peripherals. Each chapter begins with an overview that sets forth the underlying technology. Chapters outline the pros and cons of alternative upgrade options without overlooking the costs, future prospects, and timeline for a best buy, and typically end with step-by-step installation and troubleshooting procedures. In addition, Peter's Principles, Upgrade Advice, Buying Tips, Compatibility Notes, and other icons make it easy to find exactly what you need.
