Hard disk
Very sensitive to vibration, shipping computers with hard drives can not simply carry them to a place, we must prevent the generation of large shock. Because the hard disk is a complex mechanical device, installed inside the computer, tolerance is limited. A shock will hit the disc head assembly, causing the hard disk drive read-write head scratched the surface, this may damage the disk surface, potentially destroy data on the hard disk (your hard work yo!), May also be more serious damage to the read-write head, so hard disk can not be used permanently. Therefore, we must take the disk read-write head placed in the safe area, before moving; in the process of moving the action must be light; car if you intend to transport it, put it in the best position behind the car on; If by mail, keep it well wrapped up.
Motherboard
Very sensitive to static and deformation, static electricity may eclipse of the motherboard's BIOS chip and data, damage to a variety of interface-based mos transistor gates, which a bad, all the "users" (inserted above it in the card or device) are find each other, because their contact is by bus, the control chip set, the control circuit to coordinate and achieve. So, as far as possible with a soft, anti-static items wrapped board, pay attention to touch it, first touch the conductor, so that the hands of the static release, then gently. In addition, the motherboard may cause the circuit board deformation fracture, component sealing off the line on the motherboard, but close enough, you simply can not be broken. So try not to let the motherboard carry other items on the board above, it is best to carry the box into the motherboard; when installing the motherboard, must be carefully installed in the chassis stable, not the high side of the low side; in insert card, sound card or other card, note the pressure must be moderate and balanced force.
Memory
Very sensitive to overclocking, because the memory has a direct contact with the CPU, so CPU speed is the most difficult to solve the memory bottleneck. The higher the FSB, the faster the work, while the memory because the CPU needs to work in the same FSB, so overclocking the CPU, the memory is consistent with the FSB, is the key to successful overclocking, the most important Once the memory overclocking reach the desired frequency, prone to black, or even heat damage.
CPU
Very sensitive to high temperature and high voltage, although a small CPU fan protection, but with the current increase in consumption of heat generated also increases, so that the CPU's temperature will rise. High temperature tends to occur within the line electron mobility, resulting in frequent computer crashes, reduce the CPU life, high voltage is dangerous, it is easy to burn your CPU. To prevent this from happening, methods of installation of auxiliary cooling fan, cooling fan to keep it clean, regular preventive maintenance; thunder rainy day, do not open the computer and the computer's power plug appropriated; equipped with a regulator; overclocking should try not to raise the core voltage to help with overclocking, because it is worth the candle.
CD-ROM
Very sensitive to dust, vibration and poor CD-ROM, CD-ROM appear slow or does not read the disk to read the disk failure, the problem is mainly due to the laser head. In addition to the laser head itself reasons for the limited life span, the pervasive influence of dust is also a major factor in the life of the laser head. Dust not only affects the quality of the laser head to read the disk and life, the internal drive will also affect the accuracy of the various mechanical components. So to maintain the cleanliness drive is particularly important. General mechanical components for the drive to wipe with a swab of alcohol, but the laser head can not use alcohol and other cleaning agents, can be aligned using the laser blow off the dust bag. From the foregoing, the dust is the laser head of the "killer", but the shock will also bald "Disc", damage to the bald. Therefore, we choose drive earlier, the shock size is also an important reference factor, while in the CD-ROM drive, try to drive the screws tighten on both sides, let the chassis, you can reduce the vibration. CD-ROM is another poor drive the enemy, it will increase the burden of bald servo circuit, accelerated wear of the movement, speed up the aging of the laser tube. Do not know what you believe it or not, is now available in the popular DVCD drive the most dangerous enemy, because it points of light from the design standards and general drive more than a small dot pitch, drive like a nearsighted person reading it as difficult to see tiny small print, maybe someday, "the blind."
Keyboard
Very sensitive to moisture, dust, pull, and now most of the plastic membrane keyboard switch, that switch is constituted by three lines of plastic film, is a hole in the middle of an insulating film, coated on both sides of the thin film metal lines and contacts, corrosive moisture, dust will cause poor contact contact keyboard operation ineffective. Found that the situation should be very carefully open the keyboard cover with brown brush or vacuum cleaner to clear out dirt. Drag and drop easy to make the keyboard line break, so the keyboard is defective. Therefore, we must try to keep the workplace clean and tidy, especially the edge of the keyboard to clean; Do not smoke near the computer; do not eat near the keyboard; Do not drink the cup on the keyboard in the vicinity; do not live to plug keyboard; periodically cleaned with pure alcohol keyboard; when using the keyboard, try not to drag the keyboard; the keyboard when not in use, to cover shield.
Mouse
Very sensitive to dust, light, pull, and now most people are still using the optical mouse, these mice are cheap, easy to use, but the biggest problem is easy to dirty, ball and roller coated with dust on the operation of mechanical components make the mouse not working. In addition, the light will interfere with photocell received signal, will pull the same "tail" fracture, failure of the mouse. Therefore, we must regularly clean the mouse ball and rollers; to make use of special mouse pad, periodically clean the mouse pad, mouse pad to choose different materials according to different detergents, can be used to solve the problem of water is best; avoid the sun open, using the mouse.
Monitor
Very sensitive to temperature, pressure, etc., the display is the interface to communicate with people, but also the entire computer system, power-hungry, is the most easily damaged components. It is very sensitive to impact, temperature, pressure, dust, high brightness and contrast, because the tubes is very precise, instant impact will damage it, such as broken filament prone, crack pipe neck, leakage and other issues; easy to make high-temperature Power switch is damaged, the higher the temperature the more likely the switch breakdown damage, so it's great heat sink; dirt easy to make high-voltage ignition circuit. High brightness and contrast will reduce the life of the phosphor, so that the display a few years will "lose face", the color dark. So we use the computer, try not to frequent startup, shutdown, because the cold tube filament resistance is very small, just getting on the impact of current large machines, often not conducive to protecting the filament power, the other extreme of the tube also affects female; to avoid the sun light, direct exposure to high-intensity electro-optic displays, because they enhance the display of the temperature, accelerated aging CRT monitor, the monitor when not in use drop cloths cover good; such as long-term need, regular power-driven wave, generated high voltage power to prevent a sudden , resulting in burned component failure; monitor should be placed in a place with good ventilation, ventilation holes should not be placed on top of other items.
