Second, pay attention to heat dissipation in summer, avoid using computers for a long time in rooms without air conditioning, and pay attention to antifreeze in winter. Computers are actually afraid of cold.
Third, when the computer is not in use, cover the monitor, case and keyboard with a breathable and strong covering cloth to prevent dust from entering the computer.
Fourth, try not to turn the machine on and off frequently, and simply use the screen to protect or hibernate when not in use. When using the computer, don't move the chassis, don't let the computer shake, and don't plug in all powered hardware devices except USB devices when booting.
5. Using a three-pin power socket with overload protection can effectively reduce static electricity. If your hands can feel static electricity, use an enameled wire (that is, the one with plastic outside and copper wire inside), one end of which can be wound on the back plate of the chassis, the fan outlet, and the other end is preferably wound on the tap water pipe. If you can't touch the tap water pipe, look for it nearby, as long as the metal object can touch the soil.
Sixth, develop good operating habits and minimize the number of times to install and uninstall software.
Seven, follow the strict switching order, should first open the peripheral devices, such as monitors, speakers, printers, scanners, etc. , and then power on the chassis. Otherwise, power off the chassis first. At present, most computer systems can automatically turn off the power supply of the chassis. )
Eight, don't put speakers around the monitor, there will be magnetic interference. The darker the brightness of the display, the better, but the more comfortable the eyes are.
Don't put water or liquid things around the computer, so as not to accidentally knock it over and cause trouble.
Ten, many lines behind the chassis should be straightened out, don't intertwine with each other, and it is best to tie them tightly with plastic hoops or rubber bands. The advantage of this is that it is clean and does not accumulate dust, and the lines are easy to find. In case there are small animals at home, you can avoid being hurt.
Thoroughly clean the computer, especially the chassis, every six months, but under certain conditions. If you are not familiar with the hardware, it is better to touch it less.
12. Develop the habit of combining work and rest. Don't play computer all night, which is harmful to the service life of the computer and even more harmful to the body. Monitor, chassis, mouse and keyboard all have radiation, and the radiation on the keyboard is actually greater.

How to prolong the service life of computer
Now many families with conditions have bought home computers. How can we extend the service life of this expensive high-tech product? Experts suggest that the following aspects should be paid attention to:
High-temperature-resistant home computers are used continuously for too long, the internal temperature rises, and the heat is difficult to dissipate, which will cause semiconductor materials aging, short circuit and other failures. So don't use it for more than 4 hours. If you must use it for more than 4 hours, you can turn off the computer and have a rest in the middle to cool it down. In order to avoid overheating of the computer, do not let the sun shine directly and stay away from heat sources such as heating, electric stove and air conditioner. Generally speaking, the ambient temperature of home computers is 16℃~26℃.
Excessive humidity in the moisture-proof room will cause dew condensation on the surface of the machine, which will lead to corrosion and mildew of solder joints of components in the machine, resulting in open circuit or short circuit. Disks will also be moldy due to improper humidity, resulting in the destruction of stored information. At the same time, using moldy disks will also cause damage to the drive. Therefore, in rainy days, you should always turn on electricity to heat up and drive away the moisture inside the computer.
Low-temperature-resistant home computers often fail to work below 0℃ and are prone to failure. If you want to use it, you should use hot air conditioning to keep them warm and let them work at room temperature.
Smoke and dust prevention is the enemy of home computers, which may penetrate into the computer's most important storage device-hard disk, causing great damage to the hard disk. Therefore, smoking must be banned when using computers; After using the computer, it is best to let it cool for a while, and then cover it with a dust cover; When there is too much dust on the screen, it is best to wipe it from the center of the screen with an anhydrous alcohol cotton ball; Keyboard and chassis should also be dusted regularly. Dust removal should be carried out in the case of power failure.
Anti-noise All noise sources, such as motor roar, mechanical vibration, whistle sound and speaker start-up, will affect the operation of the computer and easily cause data loss and transmission errors. Therefore, the computer should be placed in a quiet place.
The internal components of anti-vibration computer are mostly connectors or mechanical structures, which will loosen under vibration, thus affecting the work of the whole machine. Therefore, the home computer should be placed on a special workbench to avoid electric shock.
Anti-magnetism Do not put the computer around magnetic objects, such as color TV, stereo, telephone, electric fan, etc. Because when they work, they will generate electromagnetic fields and destroy the information on the disk.
Anti-voltage fluctuation home computers generally work at a voltage of 220 V 10%. If the voltage is too high or too low, the computer will be overloaded or out of control. Therefore, it is best for families with conditions to be equipped with regulated power supply and uninterruptible power supply UPS. The power supply of computer and household appliances should be separated as far as possible to reduce the fluctuation impact of starting voltage and peak current of electrical appliances on the computer.
Lightning protection computer is the electronic equipment most afraid of lightning strike, because the computer has no resistance to the static electricity released by lightning, and it is often difficult to find the fault of computer components due to the interference of static electricity. Therefore, computer users should not only be protected by lightning protection devices in buildings, but also be specially equipped with lightning eliminators that can prevent atmospheric induced electricity, and anti-static carpets can also be laid in the computer room. Nevertheless, it is best not to use the computer in the bad weather of thunder and lightning, and unplug the computer to ensure safety.
Once the anti-virus computer is infected with virus, it will affect the normal work of the computer, even destroy the disk data, leading to the collapse of the whole computer system. Therefore, computers must be anti-virus. The main method is to use special disks for special planes and refuse to use other people's floppy disks. For newly purchased systems and software, virus inspection must be carried out; Important data in the system should be backed up regularly; Don't let the computer execute programs of unknown origin.

Important measures to prolong the service life of computers
Computer maintenance is an important measure to improve computer efficiency and prolong its service life.
Computer maintenance is mainly embodied in two aspects: first, hardware maintenance; The second is the maintenance of software.
The maintenance of computer hardware mainly includes the following points:
(1) Ensure that the connection between the power line and the signal line is firm and reliable at all times; (2) Clean the floppy disk head regularly (for example, three months, six months, etc.). ); (3) The computer should always be in motion to avoid long-term idleness; (4) When starting, power on the external equipment first, and then power on the host; When shutting down, you should turn off the host first, and then turn off all external devices. You can't turn it off immediately after turning it on, and you can't turn it on immediately after turning it off. Time interval should be greater than 10 second. (5) When reading and writing the floppy disk, you should not forcibly take out the floppy disk, and don't touch the exposed disk at ordinary times; (6) When operating the keyboard, don't press the keys too hard, otherwise it will affect the life of the keyboard; (7) The ribbon of the printer should be replaced in time. When the color of the ribbon is very light, especially when the color is damaged, it should be replaced immediately to avoid impurities polluting the printer needle and affecting the flexibility of the printing needle; (8) Always pay attention to cleaning the dust in the machine and wiping the surface of the keyboard and chassis, and cover the computer with a dust cover when not in use; (9) Don't move the host and other external devices at will when power is on.
The maintenance of computer software mainly includes the following points:
(1) Back up all system software. When an abnormal situation or some accidental reasons may destroy the system software, it is necessary to reinstall the software system at this time. If there is no backup system software, it will make it difficult for the computer to resume work. (2) Important applications and data should also be backed up. (3) Pay attention to cleaning up useless files on the disk economically and make effective use of disk space. (4) Avoid illegal software copying. (5) Check frequently to prevent the computer from being infected with viruses. (6) In order to ensure the normal work of the computer, use software tools to protect the system area when necessary.
In short, the use of computers is inseparable from maintenance, and attention should be paid to the maintenance of hardware and software. "
