Analysis of Common Computer Fault Detection and Maintenance Methods
Computer technology is more and more widely used in today's society and has gradually become an indispensable part of our life and work. Computer maintenance is not only the responsibility of maintenance personnel, but also the responsibility of every computer user. Some simple computer failures can be solved without looking for maintenance personnel. Therefore, it is very meaningful to know the common faults in computer maintenance and their treatment methods. This paper will analyze the common computer fault detection and maintenance methods.

First, the principle of computer system fault analysis
1 The principle of careful observation generally includes four steps: "seeing, listening, smelling and touching".
Look, there are two aspects, one is to look at the fault phenomenon, and the other is to look at the appearance. Listen, mainly listen to alarms and abnormal sounds.
Judging the fault according to the sound. Smell, mainly whether the main engine has the smell of burning. Touch mainly refers to whether the surface of the touch element has a sense of heat.
2. Think twice before you act.
Firstly, according to the observed fault phenomenon, the possible causes of the fault are analyzed. Think about how to do it before you do it. Secondly, the observed phenomena can be tried according to past experience. If the problem is not solved, try to consult relevant information to see if there are corresponding technical requirements and usage characteristics.
3, the principle of soft before hard
From the whole maintenance judgment process, we always judge whether it is a software fault first. The analysis methods are different for different fault phenomena. After the software problem is eliminated, start to check the hardware.
4, the principle of clear priorities
Sometimes you may see that a faulty machine has more than one fault, but two or more faults. First of all, we should judge and solve the main fault phenomena; After the repair, solve the secondary fault phenomenon, and sometimes the secondary fault may no longer need to be repaired.
