The cause of the motherboard failure, there are generally three aspects:
Human fault
Some friends, less knowledge of computer operation, do not pay attention to operation norms and safety when operating, so that some parts of the computer will cause damage. For example, when a device or board is plugged or removed with power on, excessive force is used to install the device or board, resulting in damage or deformation of device interfaces, chips, and boards, resulting in faults.
Environmental fault
Failure caused by the external environment generally refers to people in unknown circumstances or unpredictable, irresistible circumstances caused. Such as lightning strikes, unstable mains power supply, it may directly damage the motherboard, in this case, people generally have no way to prevent; Another situation caused by the external environment is the failure caused by temperature, humidity and dust. The symptoms of this situation are: often crash, restart or sometimes can be turned on and sometimes can not be turned on, resulting in unstable performance of the machine.
Quality fault
Component quality causes failure
This situation means that a component of the motherboard is damaged due to its own quality problems. This kind of failure generally leads to a certain part of the function of the motherboard can not be used normally, the system can not start normally, and errors are reported during the self-test process.
