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.

Software problems are not as good as reinstallation, hardware problems back to the factory for repair.

As a computer maintenance master, you must first be familiar with the use of various operating systems, Linux Windows ......

Secondly, we must learn to deal with problems, and be familiar with some error handling of the computer, such as what do the different alarm sounds of the computer mean, or the error of the blue screen ** indicates ** error? And the understanding of system services, such as the service corresponding to the remote service, which should be? Which service should be automatically obtained from IP?

What kind of service is used by the printer, etc., these need to be understood. The use of the system registry should be proficient, the computer environment variable settings should know how to use, after entering the system setting, you must know the usage of each setting, the load capacity of different systems, etc., in short, there are a lot of things, but I said that the above ones are more commonly used.

First, grasp the relationship between hardware and hardware, and the working principle of hardware.

Second, master the main body settings of the system, including detailed adjustments.

Third, use it flexibly, you can't use it to repair a computer, and there are many ways to repair a unit.

Fourth, practice a lot, accumulate experience, master the frequent failures of computers, and judge whether hard or soft failures can be made without disassembling them.

Fifth, summary: filter your thoughts, practice more, and accumulate experience.

Learning computer maintenance, can not be rushed, flexible use, not only books can solve the problem, I hope you can establish a solid and patient attitude in the future study! Hope it helps!

The basic knowledge of the computer, the configuration of the system, and the solutions to common problems can be learned by buying some relevant materials.

Excellent technology, patience and careful thinking.
