“…a comprehensive resource for PC enthusiasts and professionals alike. Packed with the latest speeds and feeds, you’ll want to keep this book on-hand as an authoritative technology reference.”

–Chris Angelini, Managing Editor, Tom’s Hardware


For 20 years, Upgrading and Repairing PCs has been the world’s #1 guide to PC hardware: the single source for reliable information on troubleshooting and fixing problems, adding hardware, optimizing performance, and building new PCs. Now, better than ever, this 20th Edition offers beefed-up coverage of the newest hardware innovations and maintenance techniques, plus more than 90 minutes of new DVD video.


Scott Mueller delivers practical answers about PC processors, motherboards, buses, BIOSes, memory, storage, video, audio, I/O, input devices, networks, Internet connectivity, power, and much more. You’ll find the industry’s best coverage of diagnostics, testing, and repair–plus cutting-edge discussions of improving performance via overclocking and other techniques.


Mueller has taught thousands of professionals in person and millions more through his books and videos–nobody knows more about keeping PCs running perfectly. Whether you’re a professional technician, a small business owner trying to save money, or a home PC enthusiast, this is the only PC hardware book you need!



  • The newest processors, including Intel’s 2nd generation Core i3, i5, i7 plus the Atom, and AMD’s new VISION series CPUs
  • 3TB (and larger) disks, 4K sectoring, partition alignment, faster SATA disk interfaces, and SSD (Solid State Drive) hard drive replacements
  • New firmware innovations, from full UEFI BIOS support to built-in motherboard flash BIOS upgrade utilities
  • Integrated video and audio, including 5.1/7.1 surround sound, HDMI, and DisplayPort connections
  • Updated PCI Express and Power Supply specifications for powering high-end video cards
  • Emerging interfaces such as USB 3.0 and Thunderbolt
  • Updated coverage of building PCs from scratch–from choosing and assembling hardware through BIOS setup and troubleshooting



Get more than 90 minutes of up-to-the minute, studio quality how-to videos–all playable on your DVD player or computer! In this edition, Scott Mueller offers true insider information about several of the key components in a PC, including hard disk drives, power supplies, motherboards, and more.


You will see hard drives completely dissected–even see an open hard drive in operation–so you can observe exactly what happens under the covers. One of the most common causes of failure in modern motherboards, power supplies, and many other PC components are bad capacitors–otherwise known as the capacitor plague. Mueller will show several real-world examples of this “disease,” so you can easily identify and perhaps even repair the problem. Finally, because external hard drives are now commonly used for supplementary storage and backups, you’ll find a complete discussion of several alternatives on the market. This includes tips and tricks for building or assembling your own flexible, high performance and highly reliable external storage drives, with several examples shown. This DVD also contains the complete 19th edition of this book in printable form, plus extensive technical reference material, a comprehensive glossary, and more!

Editorial Reviews

From Barnes & Noble
The Barnes & Noble Review
In 2003, there has been a bumper crop of new PC technology. And to help you assess it, implement it, fix it, Scott Mueller produced the indispensable 15th edition of his legendary Upgrading & Repairing PCs.

For example, this edition includes detailed coverage of AMD's Opteron, the revolutionary 64-bit processor that delivers remarkable performance without sacrificing compatibility. Intel's latest innovations are here, too -- notably the new Hyper Threading Technology, which gives you two "virtual processors" inside the same Pentium 4.

These processors have immense performance potential, but you'll need new motherboards, memories, and chipsets to deliver on it. Mueller covers the latest, hottest stuff -- from higher bus speeds to dual-channel memory architecture. Along the way, he addresses everything from processor slots to form factors, cases, and power connectors -- the details wherein the devil often hides.

He's equally strong on the "almost new" technologies now coming into widespread use. For example, as part of a detailed chapter on optical storage, he demystifies the bewildering menagerie of DVD standards (DVD+RW, DVD-RAM, DVD-R, DVD-RW). Which ones are likely to last? How do you minimize your risks? What do you need to know about copyright protection and other, umm, realities?

As the value of computers increasingly moves to the network, Mueller has increased the book's coverage of networking, from LANs to broadband Internet connectivity. This edition covers all of today's Wi-Fi wireless standards, slow to fast, cheap to expensive -- with a focus on interoperability issues.

Most computers that need repair or upgrading aren't brand new, so Mueller presents systematic coverage of mainstream technologies, including every significant PC component. You'll find entire chapters dedicated to your PC's BIOS; to hard drives; to audio hardware; to I/O devices ranging from ancient RS-232 to contemporary USB 2.0, Serial ATA, and IEEE-1394b. Where you can upgrade existing devices to get the performance offered by newer interfaces, he tells you.

He covers myriad removable storage media from today's external USB 2.0 and FireWire drives to those failed media formats that doubtless hold your Great American Novel. His detailed coverage of backup/restore issues includes exceptional guidance on trying to recover data that seems irretrievably lost (even data on formatted, repartitioned, or erased hard drives and formatted flash memory devices).

In recent editions, Mueller added a detailed troubleshooting index that identifies hundreds of common PC hardware problems and points you directly to the solutions. That's still here, but the 15th edition adds new coverage on resurrecting dead systems and tracking down the flakiness in flaky systems.

Last but definitely not least, there's a DVD-ROM with two full hours of thoroughly updated digital video, in which Mueller walks you through a laundry list of current PC maintenance and repair tasks. Thankfully, the DVD will run on your home DVD player -- so if you've taken your computer apart and you've got no idea what to do next, you can still have Mueller show you. Bill Camarda

    I first looked in this book for a serial-port pin-diagram to settle an argument at a hardware troubleshooting seminar. While browsing through I was so impressed by the quality of it's content that I immediately paid the $59.95 purchase price & comitted myself to reading it 'cover-to-cover.' I am now about 200-300 pages into the book and am even more impressed than I was at first. This book is a MUST HAVE for any good tech-support area (I recommend keeping 3-5 copies on-hand as you will end up with techs fighting for them when a call-in pops ANY hard question).

    Become an EXPERT with PCs thanks to Scott Mueller!

    Upgrading And Repairing PCs by Scott Mueller is THE reference manual for PCs. This new edition of the book covers the latest technology, while still providing plenty of knowledge regarding the older technology as well. Scott writes in a way that is precise and easy to understand, which is incredibly helpful to everyone from beginners to those with an advanced level of knowledge regarding PCs. I highly recommend this book, as well as any books by Scott Mueller, in your quest for knowledge of PCs!

    Everything you ever wanted to know about computer hardware!

    A LOT of information in one place. Could be overwhelming to the casual reader but a real find for someone what wants indepth information on computer hardware in one place. The DVD-ROM is a clear, easy to absorb, chunk of information which I recommend as a "view first" before jumping into the book. I wish I had read the book before I bought my last computer, I'll probably build my next one.

    Great Reference Manual

    This book is definitely for people who are technicians or understand the technology gibberish. If you are someone who is just learning computers this is NOT the book for as it is simply too in-depth. This book is a must-have for any technician's reference library.

    Excellent Study Guide

    This is a great book in preparing for A+ Certification. I read it and took the sample questions on the CD, for two weeks straight. I passed both portions of the exam first time out.

    Informative but not definitive

    The author appears to position this book as THE definitive guide to PC upgrade and repair. If so, this proactive assertion does an injustice to the reader. 1) I believe this book (and the 10th edition) contains a fair number of 'sins of omission and comission' (e.g., revisionist/inaccurrate computer history, incomplete understanding of x86 internals). 2) Although books of this size (1500+ pages) are rarely error-free, poetic license can be graced upon honest mistakes/typos. Opinionated diatribe warrants no such respect. It seems that at times, the author will serve opinions as bold facts. The author's take on overclocking (multiplier-lock/unlocking) is an example of this. 3) Fortunately, if you have a good grasp of x86 (PC), most of the 'hiccups' in this book will be trivial. 4) Overall, a good guide -especially to the beginner- but not THE definitive text on the subject of PC upgrade and repair. 5) This review is 100% personal opinion on the text in question. :)
