How to keep the computer healthy? Please, 3Q.

First, pay attention to dust, moisture and ventilation; Secondly, the disks should be sorted regularly (please sort according to the amount of writing on the disks, but not too frequently); Third, when the computer is turned on (especially when reading and writing the disk), don't move the host easily, which will easily damage the disk; Fourth, check the integrity and stability of the CPU and the fan of the power supply regularly after using it for more than one year. Fifth, it is necessary to clean the computer regularly and maintain personal hygiene of the computer. Your speaker has a layer of dirt, which is a bad habit! Sixth, the LCD screen must use professional cleaning solution and cleaning paper to ensure no scratches; Seventh, the maintenance of hardware is very important, but the maintenance of software can not be ignored. Be careful not to install unreliable or incorrect software. The following details: How to maintain and repair the computer How to maintain and repair the computer to maximize the service life of the computer is a problem that we are very concerned about and often face. In this article, we introduce you to the most basic computer maintenance methods and precautions, so that your computer can always be kept in a relatively stable state, just like a new one. First of all, the impact of the environment on the life of computers can not be ignored. The ideal working temperature of the computer should be 10℃-35℃. Too high or too low will affect the life of accessories. If you can, you must install air conditioning, and the relative humidity is 30%-80%. Too high will affect the performance of accessories, and even cause some accessories to be short-circuited. For example, when the weather is wet, it is best to use the computer every day or turn on the computer for a period of time. Some people think that using computers less or for a short time can prolong the life of computers, which is a one-sided view. On the contrary, if you don't use the computer for a long time, the accessories will be damaged by moisture or dust. Of course, if the weather is extremely humid, such as water vapor on the surface of the monitor or chassis, you must never turn it on at this time. Too low humidity is easy to generate static electricity, which is also unfavorable to the use of accessories. In addition, the dust content in the air has a great influence on computers. Long-term dust will corrode the circuit boards of various accessories. So it is necessary to dust the computer frequently. Computers also have requirements for power supply. The normal range of alternating current shall be 220 V 10%, the frequency range shall be 50hz 5%, and there shall be a good grounding system. If possible, UPS should be used to protect the computer, so that the computer can continue to run for a period of time when the power supply is interrupted. Second, personal usage habits have a great influence on computers. First, turn on and off the machine normally. The boot sequence is to turn on the power of peripherals (such as printers and scanners) first. If the monitor power supply is not connected to the host power supply, you must first turn on the monitor power supply and then turn on the host power supply. The closing order is reversed. Turn off the main machine power first, and then turn off the peripheral power. The reason is to minimize the damage to the host, because when the host is powered on, turning off peripherals has a greater impact on the host. After a period of time, you can't switch it frequently, because it will have a great impact on all accessories, especially on the hard disk. Generally, there should be at least 10 second between shutdown and next startup. Pay special attention to avoid turning off the computer while it is working. If the machine shuts down suddenly when reading and writing data, it is likely to damage the drive (hard disk, floppy disk, etc.). ); Never move the machine while it is working. Of course, even when the machine is not working, try to avoid moving the machine, because excessive vibration will damage the hard disk and other accessories. In addition, when shutting down, all programs must be closed first, and then exit in normal order, otherwise the application may be damaged. Third, hardware failure After installing a computer, it is inevitable that there will be such failures. These faults may be hardware faults or software faults. Generally speaking, newly installed machines are more prone to hardware failure, and the failure rate is relatively reduced after the machine runs for a period of time. For hardware faults, as long as we know the characteristics of various accessories and the occurrence of common faults, we can eliminate them one by one. 1. Poor contact fault Poor contact is generally reflected in poor contact of various cards, memory, CPU, etc. And the motherboard, or the power cable, data cable, audio cable, etc. are poorly connected. Among them, various interface cards and memory are in poor contact with the motherboard. Usually, the fault can be eliminated by replacing the corresponding slot or wiping the golden finger with the image skin. 2. Incorrect parameter settings CMOS parameter settings mainly include hard disk, floppy disk, memory, password, machine startup sequence, virus warning switch and other types. Because the parameters are not set or set incorrectly, the system will prompt an error. If the virus warning switch is turned on, Windows 95 may not be installed successfully. 3. Hardware failure Hardware failure itself, in addition to its own quality problems, may also be caused by too much load or other reasons, such as insufficient power supply or overclocking CPU, which may cause machine failure. Fourth, software failures Software failures are usually caused by improper installation of hardware drivers or virus damage. If there is no driver installed or there is a conflict between drivers, you can find some marks in resource management under Windows 95/98, including "?" Indicates an unknown device, usually the device is not installed correctly, "!" Indicates that there is a conflict between devices, and "×" indicates that the installed device driver is incorrect. The harm of viruses to computers is well known, ranging from affecting the speed of machines to destroying files or causing crashes. In order to facilitate the maintenance of the computer at any time, tools such as DOS startup disk or Windows98 startup disk, antivirus software and disk tool software must be prepared to deal with the situation that the system is infected with virus or the hard disk cannot be started. In addition, drivers of various accessories should be prepared, such as CD-ROM drive, sound card, video card and modem. The cleaning disks and cleaning solutions for floppy and CD-ROM drives should also be kept at hand to improve the computer level: if you rarely touch the computer, don't uninstall the machine. If I can't press it, I suggest my friends keep a strong curiosity and study the computer. Believe it or not, you will understand many things. 2. communicate with others, don't be so careless about what you can't do. Now Baidu has launched such a good learning atmosphere that everyone can learn from each other together. But knowledge is gradual. Then I'll make a list myself. I don't like learning computers very much. I can start by playing computer, and the most important thing is to cultivate my interest in this field. Let me give you a list of the process of learning computer knowledge. 5438+0. Play computer. I don't know anything, just playing around. Because games and computers are inseparable. I want to learn computer, but I don't know how to start. 3. Find some basic computer books to understand what computers and computer parts are. And the working principle of the computer. 4. Do more daily computer operations. Touch the computer more. Know your own system. Know the performance gap between your computer and other computers. 5. Be able to handle some simple computer failures normally. You can help your friends and relatives repair the computer, because you are learning while repairing the computer. With your gradual study, I believe your computer level will improve rapidly. Come on!
