Basic maintenance knowledge of personal computers

How to maintain and maintain a computer to maximize its service life is a topic of great concern to everyone.

Daily maintenance cannot be relaxed

The impact of the environment on computer life cannot be ignored. The ideal working temperature of the computer is 10℃-35℃, too high or too low will affect the service life of computer accessories. Its relative humidity is 30%-75%. If it is too high, it will affect the performance of CPU, graphics card and other accessories, and even lead to short circuits of some accessories. If it is too low, it is easy to generate static electricity, it is also unfavorable for the use of accessories. In addition, the dust content in the air has a great impact on computers. There is too much dust. Over a long period of time, it will corrode each accessory and the circuit board of the chip. if the content is too small, it will produce electrostatic reaction. Therefore, it is best to keep the computer room clean and tidy.

Some people think that using a computer for a short period of time can prolong the life of the computer, which is one-sided and vague. On the contrary, a computer is not used for a long time, computer Accessories may be damaged due to moisture, dust, and sweat stains. Of course, if the weather is wet to a certain extent, such as: the display or chassis surface moisture, at this time, do not dry the machine to power on, so as to avoid short circuit and other unnecessary losses.

Good personal habits have a great impact on computers. Therefore, please correctly execute the sequence of boot and shutdown. The boot sequence is as follows: peripherals (such as printers, scanners, UPS power supplies, modem, etc.), the display power supply is not connected to the host, and the display power must be turned on first, and then the host is turned on; the shutdown sequence is the opposite: Shut down the host first, and then shut down the peripherals. The reason is to minimize the damage to the host. When the host is powered on, when the peripherals are turned off, it will generate a strong impact current on the host. After shutdown, you cannot enable or shut down frequently for a period of time, because it has a great impact on the accessories, especially the hard disk damage. Generally, the next boot time should be at least 10 seconds after shutdown. Pay special attention to avoid shutdown when the computer is working. For example, if the computer is suddenly shut down when reading and writing data, it is likely to damage the drive (hard disk, soft drive, etc.), and cannot be moved when the machine is working normally. When shutdown, you should first exit the Windows operating system, close all programs, and then exit in the order of normal shutdown, otherwise the application may be damaged. Of course, even if the machine is not working, you should try to avoid moving the computer, because the excessive vibration will cause damage to the hard drive, motherboard and other accessories.

Just like we wash our faces and brush our teeth every day, computers also require you to care about her every day. General Computer Maintenance involves the following:

1. Keep the computer room dry and clean, especially the computer workbench should be cleaned every day (or two or three days, depending on the cleanliness of the room. You know, the monitor is a strong "vacuum cleaner ". Once encountered a poor environment, dust accumulation inside the display, the weather turns to tide, resulting in short circuit board fire damage the display accident.

2. Boot properly (peripherals first and then the host) and shut down. In fact, this should not be a maintenance item, but many users do not agree with this, even mistakenly think that the current computer has a "soft shutdown", but also "old saying ". However, this is absolutely necessary: if the order of "peripherals first and then hosts" is reversed, the system may fail to identify the relevant hardware or load the device driver.

3. Before using a CD or floppy disk, you must first take advantage of antivirus software. After installation or use, you must check the virus again, because some anti-virus software cannot do anything about the virus in the compressed file.

4. If the system exits abnormally or is accidentally powered off, scan the hard disk as soon as possible to fix the error in time. In this case, some of the hard disk's cluster links will be lost, causing potential risks to the system. If it is not repaired in time, it will lead to program disorder and even endanger the stable operation of the system.

Clean once in about three months.

In order to make the computer work normally for a long time, it is necessary for the user to learn how to enable the chassis for computer maintenance. Of course, if you are not sure, the package should be cleaned once a year for professionals. For some brand machines, the statement states that the chassis should not be unmounted at will, so do not open the chassis; otherwise, no warranty is given.

For hardware maintenance, it is generally impossible for users to have professional tools. We can easily deal with them using the following tools: Cross screwdrivers, lens wipes, blow balloons (pig), and paper clips, A small fan.

1. Cut off the power supply, unplug the connection between the host and peripherals, open the chassis with a cross screw driver, and remove the power supply box. You will see dust on the board, blow a balloon or pig carefully, especially the accessories of the panel air inlet and the vicinity of the power supply box (air outlet), and the plug-in part of the board, at the same time, the fan blower can be used to take away the dust on the inner wall of the dust box that is blown by the balloon.

2. Remove the power supply. The computer's exhaust is mainly powered by a power fan. Therefore, the dust in the power supply box is the most. Use a blow balloon to clean it carefully and install it. In addition, you need to pay attention to the deformation of the fan leaves, especially after the high temperature in summer, plastic aging will often make the noise larger, it is likely to be the reason.

Other fans in the chassis can also be cleaned using this method. Frequent cleanup of dust on the fan can maximize fan life.

3. Expand the paper clip, insert the emergency bomb exit hole on the front panel of the optical drive, and use a little effort to open the optical drive tray. Use the lens test paper to gently wipe the points. Be sure not to explore the drive, or use the "clean disk" on the drive.

4. Use a balloon to clear the dust from the drive.

5. If you want to remove the board, pay attention to the location accuracy, whether the slot is firmly inserted, and whether the connection is correct when installing the Board again.

6. Use the lens test paper to wipe the monitor clean.

7. Open the back cover of the mouse, remove the ball, clean it with water, and dry it.

(Optical Mouse can avoid this step, but the four pads at the bottom of the photomouse can easily stick the dust and oil stains on the desktop, and affect its smoothness. You can use hard plastic, remove the stains that are attached to the pad to restore the feel of the mouse. We also recommend that you use mouse pads of the appropriate specifications to extend the service life of the mouse pads .)

8. Use a balloon to clear the dust between the keyboard and key positions.

9. if you have a certain installation Foundation, we recommend that you re-apply the silicon grease to the CPU every five months. Although the silicon grease uses the oil with a high boiling point as the medium, it is inevitable that the application is volatile, and the grease is volatile, which will affect the connection and Heat Conduction between it and the heat sink. Therefore, it is generally about five months to re-apply the silicon, it can keep the thermal conductivity of silicon grease in the best state at all times. Of course, if you are using a better texture, such as the Arctic silver, the time for replacing the silicon grease can be extended.

As some students and friends use computers in the dormitory, the environment is worse, and the computer should be properly maintained in a timely manner. The above time can be shortened. Adding dust-proof networks to various fans and adding ventilation fans to the chassis are good methods. I believe that the maintenance and use of computers in accordance with these methods will greatly extend the service life of computers and better serve everyone.
