Motherboard burnout refers to the failure of the motherboard circuitry, causing the motherboard circuit circuit components to burn out. There may be many reasons why the motherboard burns, but the most common reasons are still these three: unstable voltage, unstable temperature, poor circuit contact.
1, voltage causes
Voltage is an important working environment of the motherboard, if the voltage is insufficient or too large, will cause some damage to the motherboard, or even burned. Too low a voltage will lead to insufficient voltage in the circuit components of the motherboard, thus affecting the normal operation of the motherboard, even leading to the motherboard burned; and too high a voltage will lead to overloading of the circuit components of the motherboard, so that the circuit components overheating occurs, which will also lead to the motherboard burned.
I often see a colleague using a desktop computer, not through the normal operation of the computer shutdown, but directly off the plug power. This operation is very easy to cause the computer's power supply appears to be instantly cut off, the power supply is not stable, easy to burn the motherboard. Some people with laptops, but also directly press the power button to shut down, directly power off these operations are caused by the computer movie is not stable irregular operation, it is recommended that we do not operate this way in the future.
Also, we do not put some metal items in the computer accessories, especially the host side, because the metal is easy to generate static electricity, placed next to the host will also affect the motherboard generates static electricity, affecting the stability of the voltage.
2, temperature causes
Temperature is an important working environment of the motherboard, if the temperature is too low or too high, will cause some damage to the motherboard, even burned. A low temperature can lead to insufficient temperature of the motherboard's circuitry components, thus affecting the normal operation of the motherboard and even leading to motherboard burnout; while a high temperature can lead to overheating of the motherboard's circuitry components, causing the circuitry components to overheat, which can also lead to motherboard burnout.
Some people don't take care of their own computers, or some public computers lack of maintenance, the components of the computer motherboard are easy to aging, the quality of the decline. Failure of the motherboard components, it is easy to cause the temperature too high or too low, and then burned. My laptop has been used for almost ten years and is getting old. But some time ago I replaced the keyboard, dusted the motherboard, upgraded the RAM and added a cooler on the advice of my computer guy. Now when I use it the software monitors the CPU and motherboard temperatures have dropped. So, the addition of equipment can assist in cooling and prevent the motherboard temperature is too high, it is recommended that you can also so operate to take care of their computers.
3, poor contact causes
Bad contact refers to poor contact between the motherboard circuit components, if the contact is poor, it will lead to insufficient or excessive voltage between the motherboard circuit components, which will also lead to the motherboard burned. If the contact between the motherboard circuit components is poor, it will also affect the heat dissipation of the motherboard, which will cause the motherboard circuit components to overheat, and also lead to motherboard burnout.
The cause of poor contact, the most common is to move, move the computer in the process of too much "violence", so we need to use the process of the computer do not "too much action", gently take the light to put a little more careful, be careful, careful to get a boat, so that the computer motherboard does not appear to be the same as the motherboard, so that the motherboard will not have the same as the motherboard. The first thing you need to do is to make sure that you have the right tools for the job, and that you have the right tools for the job.
