دانلود کتاب عیب یابی و نگهداری کامپیوتر برای مبتدیان

If trouble were predictable, it wouldn’t be a problem. That’s because the problem with trouble is that it’s unpredictable. You hold in your hands a thrill-packed book that’s all about solving computer problems. The topic is troubleshooting. It needs to be covered in so many pages here because a computer hasn’t yet been invented that didn’t have trouble following it like a shadow on a sunny day. The computing experience should be a pleasant one. And it can be — if you’re informed and able to deal with the troubles you encounter. This book helps you along that journey in an informative and entertaining way. Welcome to Troubleshooting & Maintaining Your PC All-in-One For Dummies. A byte of prevention is worth a gigabyte of cure. This book’s philosophy is that troubleshooting is easier to do when you understand how the computer works. This philosophy is the opposite of what most computer users expect, which is to look up a specific condition and find a specific cure for it. This approach has two glitches. The first downfall with the look-it-up approach is that you don’t learn anything. Because there’s a method behind PC madness, often, the same solution can be applied to multiple problems. After you understand why things go wrong, it’s not only easier to fix them — it’s also possible to prevent them in the first place. The second difficulty with the specific-solution approach is that it would make this book obnoxiously huge. With millions upon millions of potential hardware and software configurations available in all the PCs in the world, it would take several fat books to document every problem and its solution. Such a book would need to be delivered by forklift. My approach is simple: Look up the problem, learn a bit about what might have caused it, and then arrive at a solution. The notion is that when trouble arises again later, you have the experience to deal with it in a practical manner. Because most PC troubles have a common origin, this solution works. Before moving on, please be aware that there’s a difference between trouble and an event that’s merely annoying. For example, if the text you print from an email message is tiny, it’s annoying, but it isn’t a bug. Though specific annoying problems might not be covered in this book, you still can find a solution here. This is the beauty behind my philosophical approach to troubleshooting. After all, using Windows shouldn’t be a frustrating experience.
