Computer operation misunderstanding aspects _ hardware maintenance

With the increasingly civilian use of IT products, many families have bought home computers. Because of the uneven level of computer, it is inevitable that some "rookie" or even "prawn" in the operation of the computer more or less have some mistaken operation, some seemingly casual misoperation may make your computer instantly "die", and even hurt your health. Based on this, the author will be in the long-term use of computer experience and should pay attention to the misunderstanding of "clean up", in order to improve the computer level to avoid harm, so that the computer better for our work and loyal service.

One of the misconceptions: Clean the display to use high purity anhydrous alcohol

As an important medium for human-machine exchange, the display of screen is hard to be sticky with dust and stains for a long time. Many friends assume that alcohol, especially high purity (more than 95%), is the best detergent. On the contrary, the current display (CRT type) generally has a special protective coating on the screen, used to prevent static and glare, alcohol as a good organic solvent is very easy to destroy the special coating, the display of a large discount.

Correct way: monitor screen including its shell, can not use alcohol, gasoline, detergent and other solvents, if conditions, please use a special display detergent. If the conditions are not available, you can buy a few bottles of pure water on the market to clean the display screen and the shell. In addition, the screen cleaning special care, do not use ordinary coarse towels, should buy 1~2 block quality better glasses cloth generation.

The second myth: Open the chassis, so that the computer accessories inside the chassis "naked" is the best heat dissipation

Summer has reached, many "rookie" even including many diyer in order to enhance the heat dissipation or ease of disassembly hardware, have invariably chosen a cheap and convenient heat dissipation scheme-let the computer "streaking." However, I think this is a very improper move. One, although the solution of the heat dissipation, but the chassis "gut broken belly" so that hardware exposed easily accumulate dust, the "dust" will also become a computer killer. Second, this practice is very harmful to the health of the human body. As we all know, CPU, motherboard, power and other hardware are high electromagnetic radiation sources, and the chassis for us to shield the vast majority of electromagnetic radiation, is our healthy use of computer "protection of God." If only for cooling, and let our body directly exposed to high electromagnetic radiation, health jokes is not worth the candle.

Myth Three: Immediately after the shutdown of the dust cover

Many friends in the purchase of a new computer after the computer is very attention to dust-proof, specifically custom-made the dust cover, this is understandable, but shut down immediately after the dust cover on the cover can not be taken. Originally, after the shutdown of the chassis, the display also has a large number of heat is not distributed out, all kinds of electronic components of the temperature is very high, need to have a gradual cooling process, if immediately cover the dust cover, is very detrimental to the heat of the hardware, or even seriously affect its service life.

Correct approach: After 1-2 hours shutdown, the standby box in the heat dissipation to use the dust cover.

Misunderstanding of the four: with electric Plug and unplug a variety of computer peripherals

A lot of friends in the various hardware operation, for the figure is often not shut down in the case of live Plug and Unplug PS/2 interface of the mouse, keyboard and a variety of strings, and mouth equipment. These are seemingly ordinary, but very dangerous operation, light causes system or hardware work is not normal, heavy caused the hardware interface or motherboard damage.

Correct approach: In addition to USB, IEEE1394 interface and serial hard disk, general desktop various peripherals are not equipped with electric plug, so friends in other hardware operation do not be afraid of trouble, be sure to shut down the power of the case to do the right operation, so as not to cause unnecessary losses.

Misunderstanding of the five: contact with computer hardware, static electricity is not fortified

Many friends subconsciously know that static electricity is a potential "killer" of computer hardware, however, due to the importance of not enough, more operational inertia and the existence of the lucky mind, often "illegal" hardware operations, so that "spark" gently flash, the computer's motherboard, memory, graphics and other components in a short moment on the "perish "Up. As static electricity is ubiquitous in our lives, it is very easy to accumulate a lot of static electricity when we touch and repair computers, so we must take effective measures to avoid the fatal damage caused by static electricity to high precision parts in the computer.

Correct approach: First of all, to ensure the reliable grounding of the computer chassis, before opening the computer mainframe contact computer hardware, it is best to use the hand and the outside of the chassis metal parts or other grounding metal contact, through a brief contact to release the body with static electricity. In addition to the removal of computer hardware can be placed in anti-static plastic bags properly preserved in the hardware sensitive operation by wearing anti-static ring can play a very good anti-static effect. Finally, the production and release of static electricity is seasonal, especially in winter, so we should increase vigilance and cautious operation.

Misunderstanding of the six: optical drive as a "DVD player", "cleaning" CD-ROM Change killer

Many friends are now equipped with CD or DVD optical drive, in order to realize the work of the two, often light drive broadcast ordinary VCD, DVCD and DVD DVDs. In fact, this is a very bad habit. Although this temporarily convenient for their own, but in the long run will greatly shorten the life of the optical drive and finally make it "scrapped." The main reason is that the optical drive in the reading of ordinary disc will frequently change motor speed and laser head frequency, long time will cause the optical drive mechanical parts wear and laser head serious aging.

Correct approach: For the maintenance of optical drive considerations, you can copy your favorite DVD into the computer's hard drive slowly appreciate, should be as little as possible and do not use optical drive to see DVDs, but not the CD-ROM drive as a DVD player!

Optical drive as a consumable, in the use of a period of time often will appear to varying degrees of reading capacity of the problem, at this time many friends have "smart move"-to use the cleaning disc CD-ROM ordinary cleaning optical drive cleaning, in order to improve or restore the CD drive reading capacity. This is actually an understanding of the misunderstanding: domestic players including VCD, DVD because of the working principle of different, its speed is generally lower than 2X, 4X, the use of cleaning discs can play a certain role in cleaning; but now the speed of the optical drive is often around 52X, at this time the cleaning disk not only to play a role, On the contrary, due to the high-speed rotation of the disc will not only scratch or even bump the laser head, become the absolute CD-ROM "killer"

Correct approach: If you want to improve the CD-ROM drive capacity, you can ask a professional person to open the optical drive with cotton ball cleaning or appropriate increase in the power of the laser head. Of course, the best way is usually pay attention to light drive care and maintenance.

Tips: 1. The optical drive is reading the disk that is, the optical drive light is also not forced to press the eject key on the optical drive panel, the best wait for the indicator lights do not read the disk action to press the pop-up key, otherwise it is easy to make the optical drive spindle motor failure.

2. After placing the disc, pay attention not to directly with the hand to push the disc tray to make the disc into the warehousing, because the push of the intensity or angle of deviation easily caused by the drive part of the CD-ROM failure. The right thing to do is to press the eject button to automatically return the disc tray to the silo.

3. After reading the disc must be removed in time, can not be stuck in the CD-ROM drive. Because although there is no read and write operation, but the computer each boot will automatically detect and read the optical drive, which not only reduces the operating speed of the system, optical drive life also has a negative impact.

Myth Seven: Shutdown does not need to cut off the power

Often see some friends after the use of computer, for the diagram of the system in the implementation of the shutdown instructions to leave, there is no power of the host completely cut off (that is, unplug the power outlets, from the strip completely removed), and sometimes even monitors and speakers and other peripherals are still working state. This in fact to the hardware of the computer buried hidden trouble, because the system in the shutdown state did not completely cut off the power, the power supply in the chassis, the motherboard is still connected to the mains, once the voltage fluctuation or encounter lightning weather is very easy to cause the motherboard, power and a variety of peripherals completely damaged. Here to advise you, for the sake of safety shutdown must be completely cut off the power.
