Maintenance and precautions of computer hardware

Computer Use precautions





one, the mouse ball with a period of time after the dirty, cut down to dry and then put on, optical mouse can be exempted from this.





second, do not tamper with their own unknown use of the file or folder, do not understand when not to use a destructive tool or command, such as partitions (FDISK), Format (format), low lattice (Lformat), cloning (GHOST) and so on.





Three, do not casually shutdown or restart, when the panic should be held down CTRL and ALT, and then click Two or three del key hot-start, it is no longer press the reset button on the chassis.





Four, ordinary encounter abnormal situation to call the technical personnel, do not disorderly operation, lest damage computer hardware and software.





Five, if you often install software or Internet, should own genuine anti-virus software and security firewall software and upgrade on time to avoid virus or hacker attacks.  Do not be on the internet when not too familiar with the site or yellow tongue site, sometimes there are traps.





Six, received the e-mail from the stranger do not casually open, preferably directly deleted, most of them for advertising, sometimes virus or hacker program.  See small programs do not out of curiosity to download or double-click to run, many are malicious.





Seven, in time to clear their own useless procedures, documents and games, and at the appropriate time to empty the Recycle Bin.





Eight, to maintain regular hard disk. The method is to clean the right key, point properties, and point clean disk of the hard disk. Then click on the tool tag, point disk scan for error, the last point defragmentation finishing (need to turn off screen protection and some Autorun programs, the method is to point right on the desktop, point properties, point screen protection, point screen protection List of small triangle, After the selection is not determined, the permanent program closed method is the right key screen in the lower right corner of the relevant icon selected close or exit.  These maintenance according to the use of the computer often or not about one months, about three months to carry out a comprehensive disk scan (in the scan when the standard into a comprehensive), such as the occurrence of abnormal situation can not handle the call for advice.





Nine, for the computer memory has important data units and individuals, in addition to pay attention to the maintenance of software, but also should be equipped with UPS, in order to prevent power outages damaged computer hardware and software, in the area of abnormal electricity should pay special attention.





10, pay attention to the cleanliness around the computer, and should pay attention to dust, moisture, anti-static, strong magnetic field, prevent overheating, avoid direct sunlight, avoid live plug hardware (except USB devices), to avoid man-made damage and children encounter.





Computer Ten parts are afraid of





one, hard drive





hard drive is the most afraid of the vibration, large vibration will let the head components hit the disc, scratches can be bad things, repair are not easy to repair, the most important thing is that your data can not be your-painstaking care yo! Www.3lian.com





Second, motherboard





motherboards are most afraid of electrostatic and deformation. Static electricity can damage BIOS chips and data, damage to a variety of MOS transistors based on the interface of the circuit, they are bad, all the "user" (inserted on its board or devices) are not found each other, because they are connected by the bus, control chipset, control gate circuit to coordinate and implement.  The deformation of the Board may cause the circuit board fracture, component off welding, the circuit on the board is very dense, broken you can not find.





Three, CPU





CPU is the heart of the computer, it is most afraid of high temperature and high voltage.  High temperature easy to make the internal lines of electronic migration, shorten the life of the CPU, high voltage is more dangerous, it is easy to burn your CPU, overclocking should be as far as possible not to improve the core voltage to help excess, because this is not worth the candle.





Four, Memory





memory is more afraid of overclocking, once the required frequency is not reached, very easy to appear black screen, and even heat damage.





Five, optical drive





The optical drive is most afraid of dust and vibration. Dust is the laser head of the "killer", vibration will also make the bald-headed "disk", damaged bald. 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. Believe it or not, now the popular DVCD disk 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"





six, floppy drive





It is the most afraid of dust and mechanical impact, dust will plug the head, read and write errors; impact is easy to make the head component translocation, the floppy drive can be troublesome, the calibration head must use a dedicated instrument, manual correction is not impossible, it requires great patience and meticulous effort.





Seven, Power





Power is afraid of repeated power-on, shutdown. On the power-on, (www.cfaninfo.com computer knowledge Business Network feeds) switching power supply needs to establish a vibration from the start to balance the process, the oscillation process frequency instability, shock current large, it is easy to burn the switch tube.  Most of the switch tubes are burned at the moment of the boot.





Eight, monitor





display is the interface to communicate with people, but also the whole computer system power consumption, is the most easily damaged parts. It is most afraid of shock, high temperature, high pressure, high brightness, high contrast, electronic burns and so on, 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.





very 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; Electronic burns refers to the display of the failure of the bright line and bright spots, it on the screen of the most damage, so that there are obvious burn marks on the screens, affecting the bright line and shutdown highlights, should be sent to repair  , do not continue to boot.





Nine, Jian Pan





It is afraid of moisture, dust, drag. Now most of the keyboard uses plastic film switch, that is, the switch is composed of three plastic film, the middle one is a hole with the insulating film, on both sides of the film plated with metal lines and contacts, damp corrosion, dust contamination will make the keyboard contact poor, operation is not.  Drag and drop easy to break the keyboard line, so that the keyboard failure.





10, Mouse





the "Little Mouse" is most afraid of dust, light and drag. Small balls and rollers on the dust will make the mouse mechanical parts operation is not, strong light will interfere with the dust will make the mouse machine parts operation is not, strong light will interfere with the photoelectric tube reception signal, pull the same will make "rat tail" break, so that the mouse malfunction.
