> Into the computer hardware and software, the hardware is all based, so the maintenance of the hardware must be good with hardware maintenance experience to share. Tools / materials hard drive, motherboard, cpu, memory, optical drive, floppy drive, power supply, predictor, the mouse steps / method 1, the hard disk drive is the fear of shock, big shock will encounter the head assembly on the disc, may scratch the big bad, because all data on the computer are stored on the hard disk sideways, so the once hard disk is damaged, your computer all the data the city Wang Shi, suggest that you back up data to develop the habit. Second, the board and the board are most afraid of is the static deformation. Static electricity can ruin bios chip and data, damage to the kinds of interfaces based on mos gate bipolar transistor, which a bad, all the "user" (inserted in the card or device on it) have found each other, because they are linked by bus control chip set, the door control circuit to coordinate and achieve. card variant may cause plate fracture line, component sealing off the line on the board, but close enough, you simply can not be broken. Third, cpucpu the heart of the computer, it fear of high temperature and high voltage high temperature tends to occur within the line of electron mobility, shorten the cpu life span, high voltage is dangerous, it is easy to burn your cpu, overclocking should not use as much as possible to help improve the core over-voltage, because it is worth the candle. 4, more fear memory overclocking memory, once reach the desired frequency, proneblack , or heat damage. five CD-ROM drive are most afraid of dust and shock. dust is the laser head of the "killer", will head the same shock, "spinning", damage bald addition of crude CD-ROM drive is the enemy, it will increase the burden of head servo circuit to accelerate the movement of the wear and tear, laser acceleration of aging. Believe it or not, now available in CD-ROM disk is popular dvcd most dangerous enemies, because it points away from the light design standards and general drive more than a small dot pitch, drive it like a nearsighted person reading the small print to see the same tiny difficult, maybe someday, "the blind." six floppy drive it is the fear of dust and mechanical shock, dust can clog the heads, read and write errors occur; impact head assembly is easy to translocation, then the floppy drive in trouble , the corrected head not have to use a dedicated spectrograph, manual correction is not impossible, it requires great patience and meticulous effort. current computer, basically there is no floppy drive, and replace the floppy drive, the computer has just developed that would , CD-ROM is used as the mobile data storage disk to use, and it is particularly convenient. seven, fear of repeated power supply startup, shutdown. boot, switching power supply need to set up a start-up to the balance of the process, start-up process in the frequency does not stable, the impact of current, easy to burn the switch. most of the power switch is in the moment burned. eight predictor predictor is the interface to communicate with people, but also the entire computer system, power-hungry, is the most easily damaged parts of it are most afraid of is the impact, high temperature, high pressure, high brightness, high contrast, electronic burns, etc., CRT is very precise, instant impact will damage it, such as broken filament prone, crack pipe neck, leakage gas and other needs to answer the questions; high power switch is easy to damage, the higher the temperature the more easily puncture damage to the switch, so the heat sink it's great; dirt easy to make high-voltage ignition circuit. high brightness and contrast reduce the life of the phosphor, the predictor will be a few years' faces light ", the color dark; electronic means is a predictor of burns occur when the bright lines prevent and bright, its screen damage maximum, so that the screen significant burns to affect bright-line and off highlights, should immediately repair, will not continue to boot up. nine, healthy dish that fear of moisture, dust, pull and now most of the plastic membrane keyboard switch, that switch constituted by the three plastic film, the center is a hole of the insulating film, coated on both sides of the film on the metal lines and contacts, moisture corrosion, dust the keyboard contact urban poor contact, the operation is not working. drag and drop easy to make keyboard line breaks, so the keyboard is hampered. 10, the mouse only "little mouse" fear of dust, glare, and pull. ball and rollers coated with dust, the operation of mechanical components make the mouse not working, can interfere with light Dust on the operation of mechanical components make the mouse not working, would interfere with photoelectric light receiving signal, will pull the same "tail" fracture, failure of the mouse. pay attention to all of the hardware issues are a lifetime, and we had better pay attention to it!>
