I believe we all know the importance of computer motherboards, it is carrying the main hardware of the computer is an important component, can be said to be a person's overall skeleton. Computer motherboards in the computer's important role is not to be overlooked, the performance of the motherboard to a certain extent determines the performance of the computer, there are a lot of computer hardware failures because of the computer's motherboard and other parts of bad contact or damage caused by the motherboard, do the day-to-day maintenance of the motherboard, On the one hand can extend the life of the computer, more important is to ensure the normal operation of the computer to complete the day-to-day work.
The main maintenance of the computer motherboard should be dustproof and Moistureproof, CPU, memory, display cards and other important components are inserted in the host board, if the dust is too much, it is possible to make the motherboard and parts of the contact between the bad, so that the unknown fault, to your work and entertainment bring great trouble; If the environment is too humid, the motherboard is very easy to deform and resulting in poor contact and other problems, affecting your normal use. In addition, in the assembly of computers, fixed the motherboard screws do not tighten too tightly, each screw should be the same intensity, if screwed too tightly also easy to make the motherboard deformation.
Generally do not open the chassis, we are not very able to access it, I encountered the most is that some people do not know the situation or in order to save trouble, often in the case of the boot of the PS/2 interface of the mouse keyboard directly unplug or plug in, in fact, this is very dangerous, light the interface is broken (a change also want dozens of dollars ha), Heavy-related chips or circuit boards are burnt. Common computer, commonly used only USB interface and IEEE 1394 FireWire interface to support hot plug (that is, can be plugged in the case of the host). In addition, the plug-and-pull interface should be pulled parallel to the horizontal plane to prevent physical deformation of the interface.
Most of the current computer motherboards are four-ply boards, six-layer board, the use of components and wiring are very sophisticated, dust in the motherboard accumulated too much, will absorb the moisture in the air, the dust will present a certain degree of conductivity, may be the main board of different signals to connect or to the resistance, capacitance short-circuit, Causes the signal transmission error or the work point changes to cause the host to work is unstable or does not start. We encountered in the actual computer use of the host frequent crash, restart, can not find the keyboard mouse, boot alarm, and so on are mostly due to the accumulation of a large number of dust on the motherboard, then as long as cleaning the dust in the chassis after the failure of self-healing is this reason.
The motherboard to the CPU, memory, etc. to provide power is large and small capacitance, the most afraid of high temperature, the high-temperature can easily cause capacitance breakdown of the normal use of the impact. In many cases, the motherboard of the electrolytic capacitor bubble or leakage, the loss is not due to the quality of the product is not a problem, but because the motherboard's working environment caused by poor. The general bubbling, leakage, loss of capacity of the capacitor is mostly in the vicinity of the CPU, the edge of the memory, the AGP slot next to, this is because the above parts are the computer in the heat of the large, in a long time baking in high temperature, aluminum electrolytic capacitor may appear above fault.
Knowing the above, you need to consciously choose a spacious, ventilated chassis when you purchase a machine. In addition, the regular boot box dust is also essential to a work, is generally used brush lightly brush to the dust on the motherboard. Because some cards on the motherboard, chip using the form of pins, often because of the oxidation of the pin contact with the poor, can be used to rub the surface of the oxide layer and reseat. Of course, you can use the volatile chlorine ethane to clean the motherboard when you have the conditions.
