I want to learn how to troubleshoot a computer

One of the world's supernatural events, wandering children. At 12:13 p.m., a child can be seen walking in the corner of the building, his face cannot be seen, if the news is not spread 5 posts, the family will be ruined, and the heart of the child who died will be killed.

It is best to enroll in classes if you have the conditions, because these things are the most important to practice and the best to learn. You can buy some books and learn theories first.

I don't know if you're graduating now or what, if you're out of school now, you can only rely on self-study, you can buy some similar books, you can also add some related groups, some of them will be discussed in it, you can also learn like them, the most important thing about this thing is practice, you can find a related job, so that someone will take you, it will be easier to get started, only when you actually encounter some problems, can you slowly know how to use it proficiently.

Nowadays, computers are available in almost every household, and problems are not uncommon for them to occur from time to time. If the computer fails, we can use the easiest troubleshooting or replacement method to fix the computer problem. Computer problems generally fall into two categories:

System issues and hardware issues. The general solution to a system problem is to reinstall the system, while the hardware problem depends on which hardware is damaged.

Check the computer fault outside the line and inside the line. What should I do if my computer doesn't respond when it turns on? How to solve CPU problems?

Handling of the black screen of the monitor. You can modify the Power Usage Scenario in Control Panel Power Management, noting that the time to turn off the monitor is adjusted. If the problem still does not solve, then check if the graphics card, motherboard is overheating, and if necessary, add a fan .

A solution to low virtual memory. Click: "My Computer Control Panel System", select the "Virtual Memory" setting bar in the "Performance" menu, select "User-specified virtual memory settings", in the pop-up dialog box, select the hard disk with a large remaining space as the virtual memory drive letter, and specify the maximum and minimum amount of virtual memory.

Once set, press OK until you exit the Control Panel.

Hard disk space missing workaround. Win98 only counts the actual size of the files when counting the space occupied by files and folders, and does not count the disk space occupied by them, so this loss phenomenon will be caused. Win2000 has improved this problem well.

You can observe, look, play, listen, and smell first. In this way, obvious faults can be checked. The easiest way to troubleshoot is to take a look. There is no abnormality in the motherboard, memory, CPU, and power supply.

The best way is to find some accessories to replace the troubleshooting, such as replacing the graphics card with a new one, see if it can solve the fault, then replace the memory module, and so on.

You can first look at the fault displayed on the computer monitor, and then troubleshoot according to the fault. You can first look at the English displayed on the computer screen, and then translate the English, and after the translation, you can find out where the problem occurs, and you can repair these places.

1. Turn on the power of the computer and there is no reflection There may be a computer mouse and keyboard connection problem or a power supply problem Solution: Check whether the external wiring of the computer host is correct and whether the contact is good. If the first step cannot be solved; Check whether the contact between the boards is good and whether the power supply is damaged.

2. Turn on the power of the host, the host starts the alarm, but the monitor does not have any display, Solution: First check whether the connection of the monitor ** line is correct, and then judge the fault method according to the start-up sound Award motherboard BIOS about the start-up sound judgment fault method: 1 Short:

The system boots normally. Congratulations, there is nothing wrong with your machine. 2 short:

For general errors, please go to CMOS Setup and reset the incorrect options. 1 long and 1 short: There is an error in the memory or motherboard.

Try to change the memory, if it still doesn't work, you have to change the motherboard. 1 long and 2 short: The display or graphics card is wrong.

1 long and 3 short: The keyboard controller is wrong. Check the motherboard.

1 long 9 short: Motherboard flash RAM or EPROM error, BIOS corruption. Try a different block of flash ram.

Constant ringing (long sound): The memory module is not plugged in tightly or is damaged. If it still doesn't work, you can only replace a memory module.

Ringing: The power supply and monitor are not properly connected to the graphics card. Check all the plugs.

Repeated, short ring: There is a problem with the power supply. No sound, no display:

There is a problem with the power supply. Usually this fault is caused by poor contact of the graphics card or wet chassis Solution: Open the case, perform a COMS discharge, remove the graphics card, erase the gold finger part of the graphics card with an eraser, clean the graphics card slot, and reinstall the graphics card to solve the problem (remember to wash your hands with the water hose and discharge your own static electricity during the process).

No, on a computer, you can do whatever you want after backing up your data. Of course, you have to read the book before knowing the precautions and how to operate.

Computer maintenance is the best to learn, each family has experimental conditions, if you rely on the new practical down-to-earth computer repair book, less investment (to repair a computer for yourself to earn back the money to buy books), time at will, and then you can first repair the computer for yourself, friends, classmates, relatives, practice conditions are extremely abundant. After that, you can apply directly. The following books can be flipped through in the bookstore first, and look at the large number of reviews of Dangdang and Jingdong, and determine for yourself whether they are really practical.

Computer maintenance is divided into board level and chip level maintenance, and mobile phones are chip-level maintenance. In order to learn board-level maintenance in practice, chip-level maintenance requires sufficient circuit foundation, and most people can't stick to it, giving the training school the opportunity to make money without losing money.

It is recommended to start with the book to learn board level maintenance. To cultivate interest, you can see the chat-style popular science book "The Master Teaches You to Play the Computer: Hardware Introduction, Maintenance Tips" (has been printed 9 times, and if you feel that the examples are insufficient or the content is old, you can refer to "The Master Teaches You to Repair the Computer:

The latest practical cases"), if you want to open a store, you can see "Play Computer Repair and Store Service" (very comprehensive, has been printed 4 times), if you want to become an assembly computer cow, you can see "Multi-core Computer Assembly and Fault Handling Deep Technology", and more completely updated is "Complete Master of Computer Assembly and Maintenance Super Manual" (the thickest computer maintenance book in 2013, has been printed 3 times,).

If you want to try whether you can persist in learning chip-level maintenance, you can see "Computer Hardware Chip-level Maintenance Case Practice" (including motherboards, monitors, printers, etc.), if not, don't waste expensive training fees.

It's a memory problem.

If it's a problem with the system.

Either the system is poisoned or the system files are corrupted.

The problem with the monitor.,There's nothing wrong with checking the monitor link.,It's the motherboard.。

1. First of all, it must be said that it is very good to learn any skill, and it is not too easy to learn any technology of the Shanshi type.

2. The current computers are basically completely modular and integrated, so it is not too difficult to repair the leakage, as long as there is some experience, you can quickly confirm the fault in those aspects. Therefore, it is not easy to guess about learning how to repair computers and make a living from them, because most computer stores will have this type of technician. Of course, if you go to work in these shops after learning, it can really be regarded as a way to make a living, and by the way, it will be easier to make a living by learning about water and electricity installation.

3. To be truly "noble and noble", it is recommended to enter the school to systematically learn computer basics, digital circuits, network management, program design, and database management. Of course, what you learn in school is the most basic thing, and if you want to become a talent, you have to rely on yourself to practice and study more.

If you want to learn to repair computers and want to open a computer repair shop in the future, then it is necessary to master some computer repair knowledge.

What computer knowledge do you need to learn to repair a computer?

1. You must read the computer motherboard manual, the computer motherboard manual is a good thing, and I started from here when I was an intern in a computer company. There are BIOS and wiring on the motherboard, which is very important.

2. You must learn to assemble the computer, assemble all kinds of accessories into a complete computer, and also be familiar with the main accessories of the computer, such as motherboard, CPU, memory, graphics card, hard disk, power supply, monitor, etc.

3. You must learn to install the operating system, and now there are three ways to install the machine.

1) DOS startup, win98 class

2) Clone version of ghost installed, such as XP clone version, this is simple, put it in the disk and follow the prompts, it will be installed automatically.

3) Fully installed, such as XP, Win7 installed version.

4. You must learn to use DOS, you must know the basic commands, and you must be familiar with the maintenance and data backup under the PE system. This is useful for basics, such as hard disk partitioning.

5. Learn the basic settings of the system and use this ratio is complicated, such as network settings, establishing users, installing software, etc.

6. Learn to set up a local area network, this is actually simple, as long as there is an opportunity for internship, it is very fast to get started, if you talk about it, it is more complicated than the effect, and now there is a lot of knowledge on the Internet, you can go and see.

7. Use more commonly used software and be familiar with them. Such as office software, optimization software, antivirus software, etc. A lot of times people who don't know much about computers will ask you for advice.

8. Go to online forums to see the troubleshooting methods of various software and hardware, understand the common troubleshooting methods, and continue to accumulate in practice. Learn the above items, basically it's almost the same, data recovery and the like, now there are special software.
