23 computer hardware maintenance basic skills

The computer not only maintains its software, but also maintains its hardware, which not only increases the speed of your computer, but also extends the life of your computer. So what are the areas that need to be maintained? PS: The whole machine should be dustproof, high temperature resistant, antimagnetic, moistureproof, antistatic, shockproof

The computer should be placed in a clean room to avoid too much dust. Computer accessories cause adverse effects; there should be enough heat dissipation space around the computer, do not pile up debris; do not smoke during computer work, smoke can not be underestimated by the computer;

Do not have strong magnetic fields around the computer, speakers Try not to put it near the monitor, or put a disk, credit card, and meal card on the speaker to prevent it from being magnetized.

Do not place the cup on the computer table, and do not place it on the main unit, monitor, or keyboard. Above, the computer is most afraid of water, do not believe you ask it, huh, huh; do not carry the main box or make it vibrate during computer work, mainly can not bring vibration to the hard disk; if the computer is not used for a long time, the power should be cut off, but regularly Start up and run out to remove the moisture inside.

In addition, the more important point is that we should clean the computer regularly.

1. When connecting IDE devices, you should follow the principle of red and red, let the power and data lines The red edge lines are opposite so that the hardware is not burned by the insertion.

2. When installing the hardware device, if the interface is not inserted at all, check whether the connected interface is inserted or not, and the wrong connection cannot be inserted because the wrong connection is inserted.

3. According to the PC99 specification, the motherboard manufacturers have marked the corresponding colors in each interface. These colors correspond to the colors of the mouse, keyboard and speaker cable connectors, which is convenient for users to plug and unplug.

4. When you want to open the chassis panel to perform maintenance and repair on the hardware inside the host. Always turn off the power and put your hands on the wall or water pipe for a while to let off your static electricity.

5. A hardware interrupt conflict will result in a black screen. When the machine cannot be lit after replacing the graphics card and memory, consider replacing the slot position.

6. After reinstalling the graphics driver or re-plugging the graphics card, you should reset the display's refresh rate. Otherwise, the refresh rate may be automatically set to “optimized by the graphics card error. (Optimized for the eyes) 50MHz).

7. When installing the CPU fan, finally use tools such as pliers for auxiliary installation, which can control the strength and direction.

8. In the face of black screen failure caused by overclocking, we can change the CMOS jumper in the motherboard to restore the BIOS to the factory state.

9. When installing each hardware, you should fully avoid the damage caused by metal burrs on the PCB board, pay attention to the direction of the hand. 10. USB devices should not be plugged in and out after standing up, which will easily damage the USB interface and cause physical deformation.

11. For the malfunction of the graphics card and memory gold finger oxide caused by dust, everyone should use rubber or cotton to wash with alcohol, so that it will not be black.

12. When the hard disk light on the main unit panel is flashing, do not restart the computer. This will make the hard disk cause bad sectors or cause the partition table to go wrong.

13. Optical drives, hard drives, floppy drives, recorders and other hardware devices must be installed on the screws, and the screws should be stabilized to avoid the adverse effects of reading the disk or other vibrations on the hardware.

14. When only one memory needs to be installed, the memory socket close to the CPU socket should be preferred. The advantage of this is that the memory can be cleaned when the memory is contaminated by the dust from the CPU fan, and the socket is After pollution, it is extremely difficult to clean.

15. Clean the disc and monitor screen. Do not use alcohol. Use only lens paper and flannel.

16. When the optical drive does not retreat, you can use a needle to puncture the small hole on the panel of the optical drive, which can be forced to retreat.

17. Regarding the base of the monitor, the display can be turned upside down during installation, which is convenient to install and stable.

18. When the display has a dirt that is difficult to remove, use the mouth to heat the contaminated part, and then wipe it with a flannel to clean it. The effect is obvious.

19. The internal messy data line of the host, the power cord can be tied with a wire or a rubber band, which not only gives a neat feeling, but also facilitates the heat dissipation of the host.

20. Do not use the optical mouse under strong light conditions, and do not use it under a high-reflection mouse pad.

21. When installing the three-pin power socket of the CPU cooling fan, connect the CPU fan connector on the motherboard so that the fan speed can be detected and displayed in the BIOS.

22. Do not put the phone next to the monitor or speaker, because the text message or incoming call will interfere with the operation of the speaker and display, making noise and showing ripples.

23. The computer has been used for a long time. At least the interior of the main unit should be cleaned and maintained in the first quarter, and the display should be demagnetized once.
