And, since there is a lot of serious information to be covered in this book, that really helps to ease the reader into the process. Overcoming the fear of messing something up worse than it already is is the most important step in doing your own computer repairs, and having clear instructions in front of you goes a long way toward giving the new computer repair person confidence.
The most problems, the most solutions As one might expect, the Hardware and Software chapters are the biggest in the book.
How to Troubleshoot Basic Computer Hardware Problems
Each chapter has subsections for common problems, and starts off with an overview of what's supposed to happen and what could go wrong. The Hardware section starts out with a chapter called "Let There Be PC" that is divided into sections that give a quick overview of common problems.
Each of these sections has chapters titled "What happens" and "What can go wrong. This is a very helpful resource and it makes finding the solutions very easy. Then it works its way gradually into operating system issues, shutdown issues, storage issues, video issues and the many problems one can have with peripherals.
It's not till page that the book suggests that it might be time to open up the computer case, allowing the reader to build up some confidence for that along the way.
Once the "Oh my gosh, I have to open up the case" issue is dealt with, fixing problems with loose cables, heat buildup and the power supply seems pretty simple.
The book also explains how to add more memory, more cards, and more storage, all of which are simple tasks that can appear scary to the newcomer. In my experience with computer repair, software problems seem to drive people crazy more often than hardware problems, and for good reason. Despite all of Microsoft's best efforts, Windows doesn't always behave the way most of us think it should, and Microsoft's programmers seem to love error messages that are either too cryptic to understand or don't tell you what's really wrong.
The Software section takes a careful, reasonable, step by step approach to each common problem, which is absolutely the best way to think things through. It walks the user through computer jargon like programs, processes, and services, explains Safe Mode and how to use it, and then does a good thorough job of showing the reader how to be an efficient troubleshooter.
It deals with user accounts and User Account Control , system resources and data recovery, and then deals with the Registry. I found it rather odd that several pages of instructions on editing the Registry ended with a stern warning not to mess with it.
That's an excellent warning, but why tell people how to mess around with the Registry even with instructions to back it up first and then say Don't Do It?
Although the Software section does deal with other versions of Windows, its primary focus is on Windows 7, and quite frankly, I think this section alone is worth the price of the book. Thinking smaller, thinking bigger The section on Laptops is arranged in the same order as the previous sections, beginning with power and startup issues common to laptops. It talks about heat buildup and the problems that can cause, and mentions cooling devices that may be useful.
There's a section on the Windows Mobility Center, which is something I didn't know existed till I read the book, but will be checking regularly from now on.
There's advice on buying a laptop bag, and sensible precautions to take when you travel, and a short section on laptop maintenance, which in this case mostly means cleaning things off without causing damage. While it talks about buying more memory and larger hard drives, it doesn't go into detail about how these things are installed. I think either there should have been a generic explanation of how these hardware updates are done, or there should have been a warning to leave these things to an experienced technician.
Some manufacturers make memory and hard drive replacement a lot easier than others, and laptop users should be aware of this. Web woes and beyond The Internet section is fairly short, but packed with useful advice. I especially liked the section on broadband modems. A lot of Internet-connection problems can be solved with a bit of knowledge about modems, and this section could save plenty of time and frustration trying to get through to your ISP's call center.
Many people would consider this worth the cost of the book.
There's also a good long section describing common problems with dial-up connections, and this also is well worth reading. If either of these cords can be detached from the brick, try again with a known good cord if you have one. If you've got a desktop, you'll usually just have one cable to check, the one that goes from the outlet to the back of the computer.
Again, a known-good power supply will tell you exactly which is the problem, but be sure to check for things like the aforementioned motherboard status light—if it lights up when the computer is plugged in, it may point to a motherboard issue rather than a power issue. If the battery is less than a year old, you may be able to get a replacement. Most laptop manufacturers will insist you buy a first-party battery to avoid voiding the warranty on the rest of the computer.
Memory Symptoms: Blue screens or crashing applications, computer powers on but will not boot, other erratic behaviors. Memory errors can be hard to diagnose since they're often intermittent, but they present most often as general system instability: individual applications or the entire operating system may crash, the system may sometimes refuse to boot.
And you may even experience graphics corruption, since the integrated graphics processors used by many computers today use the same memory as the rest of the system.
For more serious memory errors, the computer may power on and beep or make the power light flash a certain number of times without attempting to boot from the hard drive. Consult your computer's manual to see if these correspond with any known error codes. Your first step in troubleshooting this problem is going to be a good memory diagnostic tool. But there are some good general-purpose alternatives if your computer shipped without one of these tools.

Windows 7 comes with its own memory diagnostic, which can be run from within Windows 7 or from the Windows 7 install media. The tool will automatically start testing your memory and will keep making additional passes until you shut the computer off.
Generally, if the tool hasn't found an error after two or three passes, it's not going to. This can help you isolate the issue to one of the RAM modules. Hard drive Symptoms: Slow or inconsistent performance, errors when attempting to access files, computer unable to boot, louder-than-usual drive clicking or activity noises for mechanical HDDs only.
Scheduling a disk check with Chkdsk, Windows' built-in disk checking tool. Losing the hard drive in a computer is one the most devastating failures you can experience, since the data is often the most valuable part of the computer. Even if all of the other components fail, the drive can still be pulled and the data transferred. Chkdsk is normally run in one of two ways, depending on whether you can get your computer to boot or not.
If your computer can boot, you can initiate the scan from within Windows.You must be logged in to post a review. Drives of this type are small units, similar to those used in full-feature laptops, that draw electrical power from wall current and connect to the computer through the USB port.
What has changed is the integration scale, the ability of the peripherals, and the size and capabilities of the software. Most power bricks have two cords: one that runs from the outlet to the brick, and one that runs from the brick to the computer. Generally, if the tool hasn't found an error after two or three passes, it's not going to.
