Protection of computer hardware

CPU: Avoid high temperature and high voltage





Although the CPU has a small fan protection, but with the increase in the consumption of electrical energy generated by the increase, so that the temperature of the CPU will rise. High temperature easy to make the internal lines of electronic migration, resulting in frequent computer crashes, shorten the life of the CPU, high voltage is dangerous, it is easy to burn your CPU.





to prevent the occurrence of the above situation, the method has installed auxiliary cooling fan, cooling fan to keep clean, regular preventive maintenance; Thunder rainy Day, do not turn on the computer, and the computer's Power plug dial, with a voltage regulator, when overclocking should not use to improve the core voltage to help overclocking, because this is not worth the candle.





hard drive: To prevent large vibration





transport with hard drive computer can not simply carry them to a place, should pay attention to prevent some large vibration of the production. Because the hard disk is a complex mechanical device, installed inside the computer, tolerance is limited. A large vibration will allow the head assembly to touch the disc, causing the hard disk read and write head cut disk surface, which may damage the disk surface, potentially damaging the existing hard disk data (your effort yo!). , it is also possible to damage the read-write head and permanently make the hard drive unusable.





So, we have to put the head and writer in the safe area of the disk, before moving it, you must move lightly in the process, and if you plan to transport it with a car, it is best to put it in the back of the carriage, and if it is mailed, please wrap it nicely.





motherboard: Light handle to prevent electrostatic damage





electrostatic may eclipse BIOS chips and data on the motherboard, damage to a variety of MOS transistors based on the interface of the circuit, they are bad, all the "user" (plugged into the board or devices on it) are not found each other, because they are connected by the bus, control chipset, control circuit to coordinate and implement.





So, we should try to use soft, anti-static goods package motherboard, pay attention to touch it with the hand, to first touch the conductor, so that the electrostatic release of the hands, and then gently handle.


another


Outside, the motherboard deformation may make the circuit board fracture, component off welding, the motherboard on the line is very dense, broken you can not find. So that when I carry my motherboard, I try not to put anything else on the motherboard, it is best to carry it in the motherboard box; When installing the motherboard, be sure to carefully install it smoothly on the chassis, not on the side of the high side; when inserting a video card, sound card or other card, pay attention to moderate pressure, balanced application.





Memory: Be careful over overclocking





because memory and CPU have a direct connection, so memory is the most difficult to solve CPU speed bottleneck. The higher the FSB, the quicker the work speed, at the same time, memory due to the need to work in the same CPU FSB, so when the CPU overclocking, the memory is consistent with the FSB, is the key to overclocking success, the most important is overclocking once the memory can not reach the required frequency, very easy to appear black screen, and even heat damage.





Optical drive: Keep away from dust and vibration; do not use coarse discs





Optical drive appears to slow reading disk or do not read the disk failure, mainly caused by laser head problems. In addition to the limited lifetime of the laser head, pervasive dust is also a major factor affecting the life of the laser head. Dust not only affects the quality and life of the laser head, but also affects the accuracy of the mechanical parts inside the optical drive. So it's especially important to keep the CD drive clean.





for the optical drive mechanical parts generally use cotton swab alcohol can be wiped, but the laser head can not use alcohol and other cleaners, the use of air bags aimed at the laser head blow off dust.





from the above, dust is the laser head of the "killer", but the vibration will also make the bald-headed "disk", damaged bald. Therefore, when we choose the optical drive, the vibration size is also an important reference factor, at the same time, in the installation of optical drive, as far as possible the screws on both sides of the drive to tighten, so that it is fixed on the chassis, can also reduce its vibration.





Another coarse optical disc is also the enemy of the optical drive, it will increase the burden of the bald servo circuit, speed up the movement of the wear, speed up the aging of the laser tube. Do not know you believe it, now the popular DVCD is the most dangerous optical drive of the enemy, because it's light point distance and ordinary optical drive design standard point distance is much smaller, optical drive reading it is like a nearsighted person to see the teeny-tiny print as difficult, perhaps the day will be "blind."





Keyboard: Be careful of moisture, dust, drag to bring damage





Now most of the keyboard is used plastic film switch, that is, the switch from the three-wire plastic film, the middle of an insulating film with holes, on both sides of the film plated with metal lines and contacts, damp corrosion, dust contamination will make the keyboard contact is bad, operation is not the spirit. After discovering this situation, you should carefully open the back cover of the keyboard with a brown brush or vacuum cleaner to remove the stolen goods. Drag and drop easy to break the keyboard line, so that the keyboard failure.





So, we should try to keep the workplace clean and tidy, especially on the edge of the keyboard to clean, do not smoke near the computer, do not eat near the keyboard, do not put the water Cup near the keyboard, do not plug the keyboard on the line, regular use of pure alcohol scrubbing keyboard, use the keyboard, try not to drag the keyboard When the keyboard is not in use, cover the protective cover.





Mouse: The biggest killer is dust, glare, drag





now most people use the mouse based on the trackball, this kind of mouse cheap, easy to use, but the biggest problem is easy to dirty, small balls and rollers on the dust will make the mouse machine parts do not work. In addition, the strong light will interfere with the photoelectric tube reception signal, pull the same will make the "rat tail" break, so that the mouse failure.





So, we have to regularly clean the mouse ball and roller axis, as far as possible use of special mouse pad, regular cleaning mouse pad, mouse pad according to different materials to choose different detergent, can solve the problem with water is the best to avoid in the sun to open, use the mouse.





Monitor: High temperature, high pressure can cause damage





display is the interface to communicate with people, but also the whole computer system power consumption, is the most easily damaged parts. Its most bogey is the impact, high temperature, high pressure, dust, very high brightness and contrast, because the picture tube is very precise, instantaneous impact will damage it, easy to occur such as broken filament, crack pipe neck, air leakage and so on; High temperature easy to make power switch tube damage, the higher the temperature switch tube more easily breakdown damage, so it's very large heat sink ; The dust makes the high-voltage circuit ignite easily. High brightness and contrast will reduce the life of phosphor, so that the display in a few years will be "no light", the color is dim. 3lian.com





So we use the computer, as far as possible not to the frequency of the boot, shutdown, because the tube's filament cold resistance is very small, just boot when the impact current is very large, frequent boot is not conducive to protection of the filament, in addition to the picture Tube Yin Extreme also have influence; to avoid sunlight, high-intensity electro-optic direct exposure to the display, because they will increase the temperature of the display Accelerated Display tube Aging, the monitor is not used when the cover cloth cover good, such as long-term use, should be regularly added to the electric drive, to prevent the sudden start of a high-pressure fire, causing burnout components fault; the display should be placed in a good ventilation, the top of the cooling hole do not place other items.
