【 Weak current college 】 computer maintenance and repair is important---Power By 【 China power house network 】

Maintenance and maintenance of a computer, the maximum extension of its service life, we are very concerned about the topic.
Daily maintenance not relax
Environmental effects of the computer cannot be ignored. Computer ideal working temperature is 10 ° c-30 ° c, is too high or too low will influence the life of computer accessories. The relative humidity is 30%-80% is too high can affect CPU, video card, and other parts of the performance to play, or even cause some parts of the circuit; too low easy to produce static, also on the use of accessories. In addition, the air of dust content on computers are large. Too much dust, forever will corrode various accessories, chip circuit board; content is too small, it will generate static response. Therefore, the computer room best kept clean and tidy.
Some people think that using computer fewer or shorter amount of time, you can extend the life of a computer, this is one-sided, fuzzy views; instead, the computer long time no, due to humidity or dust, sweat and other reasons, may cause damage to computer accessories. Of course, if the weather is humid to some degree, such as monitor or have moisture on the surface of the chassis, you should never give not drying machine is powered on, so as not to cause a short circuit, causing unnecessary damage.
Good personal habits influence on the computer. So please properly post and shutdown sequence. The order of power: peripherals (such as printers, scanners, UPS power supply, Modem, etc.), the monitor power is not connected to the host, but also the first power on the monitor, and then open the host; shutdown order, on the contrary: the first gateway host, and then close the peripherals. The reason is to reduce the damage to the host. Because the host is powered on, turn off peripherals moments, no host produces a strong current. Shut down after a period of time, cannot open, shutting down frequently, because the impact of the various parts, especially on a harddrive's injury more serious. General shutdown space after the next boot time should be at least 10 seconds. Pay special attention when computers work, you should avoid shutdown actions. Such as: computer is read and write data to the sudden shutdown may damage the drive (hard drive, floppy, etc.); nor can the machine when you move the machine to work properly. Shutdown, you should be aware of the Windows operating system first exit, close all programs, and then press the normal shutdown sequence, or they may damage the application. Of course, even if the machine does not work, you should try to avoid moving the computer, because excessive vibration on the hard drive, motherboard, fittings damaged.

Just like our daily wash my teeth, the computer will also need your daily for her care, General PC preserving the following points:

1. maintain resettlement computer room drying and cleaning, especially computer Workbench to every day (or two or three days, depending on the cleanliness of the room). You know, the display is a very strong "vacuum cleaner". Have you experienced because adverse environment, monitors internal dust thicker, weather tide, causing the circuit short-circuit arcing damage display.

2. right turn (after host first peripherals) and shut down. In fact, this shouldn't be the maintenance of content, but many users of this total, or even incorrectly think that computer with "soft off", but also the "cliché". However this is necessary: "after the host first peripherals," order if reversed, it is possible to make the system cannot recognize the related hardware, or cannot load the device driver.

3. before using a CD or floppy disk, be sure to first antivirus; install or use it to look after it, as some kind of software to compress files in the virus could do nothing about it.

4. system abnormal exit or unexpectedly, scan the hard disk should be conducted as soon as possible, repair errors in a timely manner. Because in this case, the hard disk of some cluster link is lost to the system resulting in potentially dangerous, if not timely repair, will cause some programs to disturbance, even endanger the stability of the system.

Remember to clean once a year

In order to be able to let the computer long work correctly, the user has the necessary learning open chassis for computer maintenance, of course, if you are unsure, or packages for professionals to clean every year, some brands of machines, manual affirmed not free break-chassis, do not open the case, otherwise it is not given warranty.

To perform hardware maintenance, users are not likely to have a professional tool that we use the following tools to easily fix: Phillips screwdriver, lens wipe paper, and blow the balloon (leather Tiger), paper clip, a small desk fan.
1. cut off the power, will host and peripheral line pull between, Phillips screwdriver, opening the case and remove the power supply box. You will see in the dust on the Board, with blow balloons or skin tiger carefully blowing wipe, especially Panel air intake accessories and power supply box (outlet) nearby, as well as the Board of docking position, both desk fan blowing, to blow the balloon will be blown up dust box enclosure wall of dust away.
2. remove the power supply, computer power supply exhaust fan and depends, therefore the power box dust up, blow the balloon carefully cleaned after loading. Also note the fan leaves have a deformation, especially after a summer of high temperature, plastic of aging is often larger, the noise is likely to be the cause.
3. expand the paper clip, into the optical drive on the front panel of the emergency eject hole, a bit hard and optical drive tray opens. With lens paper to gently wipe and clean, careful not to probe into the CD drive inside, do not use the DVD player on "clean up" for cleaning.
4. used to blow the balloon clear of dust in the floppy drive.
5. If you want to remove the cardagain to install when the location is accurate, the slot is seated, the wiring is correct, and so on.
6. use lens paper to wipe clean the monitor.
7. open the rear door of your mouse, remove the small ball, wash with clean, dry and clean.
8. use the keyboard keys to blow the balloon will dust cleared between.
