Xp system displays season and weather.

First, turn on the computer regularly, especially in the wet season, otherwise the case will be short-circuited when it is wet, and the computer that is often used is not easy to break down. But if there is no lightning rod around the house, don't turn on the computer when it thunders and unplug all the plugs.

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. (In addition, the brand machine is not suitable for this, because it will destroy the seal and thus lose the warranty qualification. )

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.

In addition, special attention should be paid to heat dissipation in summer, and it is generally better to turn on the machine for about two hours continuously! In fact, the current computer self-protection mechanism is relatively perfect. If it is overheated for a long time, it will crash or restart. In this case, you should be careful. It is best to turn off the computer, let it have a good rest, and let yourself have a good rest. ^_^

===================================================

Maintaining a computer to maximize its service life is a topic that everyone is very concerned about.

Don't relax in daily maintenance.

The influence of environment on computer life can not be ignored. The ideal working temperature of the computer is 10℃-30℃. Too high or too low will affect the life of computer accessories. Its relative humidity is 30%-80%, too high will affect the performance of CPU, graphics card and other accessories, and even cause some accessories to short circuit; Too low is easy to generate static electricity, which is not conducive to the use of accessories. In addition, the dust content in the air has a great influence on computers. If there is too much dust, it will corrode the circuit boards of various accessories and chips for a long time; If the content is too small, electrostatic reaction will occur. Therefore, it is best to keep the computer room clean and tidy.

Some people think that using computers less or for a short time can prolong the life of computers, which is a one-sided and vague view; On the contrary, if the computer is not used for a long time, the computer accessories will be damaged due to moisture, dust, sweat stains and other reasons. Of course, if the weather is humid to a certain extent, such as: there is moisture on the surface of the monitor or chassis, don't start the machine without drying at this time, so as to avoid unnecessary losses such as short circuit.

Good personal habits also have a great influence on computers. Therefore, please perform the startup and shutdown procedures correctly. The boot sequence is as follows: peripheral devices (such as printers, scanners, UPS power supplies, modems, etc. ) should be turned on first, and then the monitor power supply is not connected to the host; The shutdown sequence is reversed: turn off the host first, and then turn off the peripherals. The reason is to minimize the damage to the host. Because when the host is powered on, it will produce a strong impact current to the host at the moment when the peripheral is turned off. 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, the time between shutdown and next startup should be at least 10 second. Pay special attention to avoid turning off the computer while it is working. For example, when the computer suddenly shuts down when reading and writing data, it is likely to damage the drive (hard disk, floppy disk, etc.). ); You can't move the machine when it is working normally. When shutting down, you should pay attention to exit the Windows operating system, close all programs, and then exit in the normal shutdown order, otherwise the application may be damaged. Of course, even when the machine is not working, try to avoid moving the computer, because excessive vibration will damage the hard disk, motherboard and other accessories.

Just like we have to wash our faces and brush our teeth every day, the computer needs your concern for her every day. General computer maintenance has the following points:

1. Keep the computer room dry and clean, especially the computer workbench should be dusted every day (or two or three days, depending on the cleanliness of the room). You know, the monitor is a powerful "vacuum cleaner". I have encountered an accident in which the circuit board was short-circuited and caught fire due to the bad environment, thick dust inside the display and tidal turnover, which damaged the display.

2. Correct startup (first peripheral, then host) and shutdown. In fact, this should not be regarded as the content of maintenance, but many users always disagree, and even mistakenly think that the current computer even has a "soft shutdown", which is also a "cliche." But this is absolutely necessary: if the order of "peripheral first, then host" is reversed, it may make the system unable to identify related hardware or load device drivers.

3. Before using CD or floppy disk, be sure to kill virus first; Check the virus again after installation or use, because some antivirus software can't compress the virus in the file.

4. If the system exits abnormally or loses power unexpectedly, scan the hard disk as soon as possible and fix the error in time. Because of this, some cluster links of the hard disk will be lost, which will cause potential danger to the system. If it is not repaired in time, it will lead to some program disorder and even endanger the stable operation of the system.

Remember to clean it once a year or so.

In order to make the computer work normally for a long time, it is necessary for users to learn to open the chassis for computer maintenance. Of course, if you are not sure, you should entrust a professional to clean it once a year. For some brand-name machines, it is stated in the instructions that you can't open the chassis at will, so don't open the chassis, or you won't be guaranteed.

It is impossible for ordinary users to have professional tools for hardware maintenance. We can do it easily with the following tools: cross screwdriver, lens paper, balloon blowing (leather tiger), paper clip and a small desk fan.

1. Cut off the power supply, unplug the connection between the host and peripherals, open the chassis with a Phillips screwdriver, and take out the power box. You will see dust on the board. Blow carefully with balloons or leather tigers, especially near the accessories such as the air inlet and power box (air outlet) of the panel, and the plug-in part of the board. At the same time, a desk fan is used to blow air to take away the dust on the inner wall of the chassis of the dust box blown up by the balloon.

2. Remove the power supply. The exhaust of the computer mainly depends on the power fan, so the dust in the power box is the most. Clean it carefully with blowing balloons and then install it. In addition, we should pay attention to whether the blades of electric fans are deformed, especially after the high temperature in summer, the aging of plastics often makes the noise bigger, which is probably the reason.

3. Unfold the paper clip and insert it into the emergency eject hole on the front panel of the CD-ROM drive. With a slight force, the CD-ROM tray will open. Wipe everything gently with lens test paper. Be careful not to enter the CD-ROM drive or use the "cleaning disk" on the CD-ROM drive for cleaning.

4. Blow the balloon to remove the dust from the floppy drive.

5. If you want to remove the board, pay attention to whether the position is accurate, whether the slot is firmly inserted and whether the connection is correct.

6. Wipe the monitor with lens test paper.

7. Disassemble the back cover of the mouse, take out the ball, wash it with clear water and dry it.

8. Blow balloons to clean up the dust between keyboard keys.
