【 Weak current College 】 should prevent what happens in the computer hardware

1. hard drive-fear of vibration

Shipped with the hard drive of the computer can not be simple to carry to a place, it is necessary to pay attention to prevent some shock. Because hard drives are complex mechanical devices, installed in the computer itself, tolerance is limited. Shock will let head component encountered platter, arising from the hard disk read-write head pierced the disc surface, this may damage the disk surface, potentially undermine the existence of data on the hard disk (for your hard work!), more serious may also damage the read-write head and make the hard disk cannot be used. Therefore, we must put read-write head and placed in the disc's security zone, and then to move; in the process of moving to action light; if you plan to use vehicle to transport it, it is best to put it in the compartment at the back of the location; if by mail, please send it very well wrapped.

2. the Board-fear of electrostatic and deformation

Electrostatic discharge may cause erosion of the motherboard BIOS chip and data, damage to the various interfaces based on mos transistor, a gate circuit, all the "user" (inserted in the card or device) are unable to find each other, because they are linked by bus, chipset, control circuit for coordination and implementation. Therefore, we try to use soft and anti-static material package motherboard, note the hand touch it, the first touch the conductor, the hands of the electrostatic discharge, and handle with care. In addition, the Board of deformation may make the PCB solder cracking, component, motherboard line but very dense, broken you simply cannot be found. So, I bring the motherboard to let other items placed on the Board above, you'd better put it on the motherboard in the box; the installation of the motherboard, be sure to carefully to its stable of installed in the chassis, not side high side low; in the plug in the video card, sound card or other cards, attention must apply light pressure is moderate, balanced.

3. memory-fear of overclocking

Because the memory and CPU has a direct link, so the memory is a CPU speed of the most difficult to resolve bottlenecks. FSB, work faster, at the same time, the memory due to the need to work in the same FSB CPU, so when the CPU overclocking, the memory and FSB Overclocking with consistent, is the key to success, the most important is Overclocked once the memory is not up to the desired frequency, and very easy to see a black screen, even generate heat damage.

4.CPU-fear of high temperature and high voltage

Although the CPU fan with small, but with the increase in consumption current generated by increasing the heat, so that CPU temperature will rise. High temperature easily make internal circuits, electronic migration occurs causing computer often panic, shorten the life of a CPU, high voltage is dangerous, it is easy to burn your CPU. To prevent this situation from occurring, methods are equipped with auxiliary cooling fan, cooling fan to keep clean and regular preventive maintenance; Thunder on rainy days, do not open the computer and the computer's power plug to disconnect; equipped with voltage regulator; where possible, not when overclocking with improving the core voltage to help overclocking, because it is not worth the candle.

5. optical drive-fear of dust, vibrations and poor CD

The drive appear slower disk read or not read the disc's fault, the main problem is the laser head. In addition to the laser head their own life limited, the pervasive influence of dust is also the service life of the laser head. Dust not only affects the laser head read disc quality and life, will also affect the mechanical parts inside the optical drive. So keep the drive cleaning is very important. For the optical drive of the mechanical parts of general use a cotton swab alcohol wipe, but the laser head can not use alcohol and other cleaning agents, you can use balloon alignment laser head blown off dust. From the dust is the laser head of "killer", but the motion also makes the bald "play disc", damaged bald. So, we first Optional optical drive, the size of the vibration is also an important reference elements, while at the same time, the installation CD or DVD drive, try to drive the screws tightened on both sides, so that it is secured, you can reduce the shock. Another poor CD is the enemy of the optical drive, it will increase the burden of bald servo circuit, accelerated movement of wear, accelerate the aging of the laser tube. Do not know you believe it or not, now available in the popular DVCD is the drive's most dangerous enemies, because its light point distance and ordinary optical design standard pitch smaller, optical drive read it like a myopic people read the small print as difficult as the fly head, any day of the "blind".

6. keyboard-the most afraid of moisture, dust, pull

Now most of the keyboard are made from plastic film switch, the switch from three lines of plastic film, the middle one is the insulating film with holes, the two sides of the film plating on metal lines and contact corrosion, moisture, contamination of dust may cause bad keyboard contacts, the operation failed. Discover this situation should be very careful to open the rear cover of the keyboard Brown brush or vacuum cleaner will be stolen goods clear out. Drag the keyboard cable rupture easily, so that the keyboard failure. Therefore, we try to keep the workplace clean and tidy, in particular the keyboard side to clean; don't smoke near the computer; do not eat in the vicinity of the keyboard; not to drink the Cup on the keyboard; do not live near to plug the keyboard; periodically with pure alcohol pad; use keyboard, try not to drag the keyboard; the keyboard when not in use, to cover the protective cover.

7. the mouse-fear of dust, light, pull

Now most people are using are still based on trackball mouse, the mouse is inexpensive, easy to use, but that's a big problem, it is easy to clean, small balls and rollers on the dust will make the mouse mechanical parts operates. In addition, the glare will interfere with the photoelectric tube accept signals, pull the same cause the rupture of the "Sage", so that the mouse is out. Therefore, we have regular cleaning mouse balls and rollers; use of special mouse pads, periodically clean the mouse pad, mouse pad to select according to different materials, different detergent can solve the problems it is best to water; avoid Sun open, using the mouse.

8. monitor-fear of high temperature, high pressure, etc.

The monitor is to communicate with peopleInterface, the entire computer system in large power consumption, is the most easily damaged parts. It is the most exclusive, high-temperature, high pressure and dust, high brightness and contrast, and so on, because the picture tube is very precise, instant impact will damage it, prone to crack such as broken filament, neck, high-temperature gas leakage; easy damaged the power switch, the higher the temperature tube switching easier breakdown damaged, so it's a large heatsink; dust easily make high voltage circuit brand impact. Very high brightness and contrast can reduce the life of the phosphor, so that the monitor is used in a few years would be "features Matt", the color fade.

So we use the computer, try not to frequent power on, power off, because the picture tube filament cold resistance is very small, just when the current post is large, frequent post not conducive to the protection of filament, in addition to the CRT-cathode degree also influence; to avoid sunlight, high strength electro-optic direct irradiation monitor because they enhance the display of temperature and speed up the monitor CRT aging, monitor when not in use cover cloth cover is good; if not, it should be regularly over a long period of power drives surge to prevent sudden power-producing high voltage spark, resulting in a burnt component failure; the monitor should be placed in the ventilation good local, the top cooling vents do not place the other items.
