Computer hardware Fault Classification

Computer hardware failure refers to the computer's board parts and external equipment, hardware circuit damage, poor performance or mechanical problems caused by the fault, serious often accompanied by the hair hot, ringing, electric spark and so on.

According to the different parts of the fault, the breakdown of computer hardware is as follows:

(1) Components and chip failure

Components and chip failure is due to computer motherboards and other components of components and chip damage caused by the failure, repair such failures are usually the replacement of damaged components and chips.

(2) Wiring and connector failure

Wiring and connector failure is due to the connection or connectors caused by bad contact, such as the hard drive signal cable and the motherboard on the IDE interface is not good, repair such failures will usually connect the wiring or connectors again.

(3) components caused by the fault (manufacturing process, electromagnetic interference)

The fault caused by the parts is that the parts are not working properly due to the quality problems of the parts themselves or external electromagnetic interference, and the repair of such faults usually requires replacing the faulty parts or eliminating electromagnetic interference.

(4) Hardware incompatibility caused by the failure

Hardware incompatibility failure refers to the failure of a computer with more than two parts to work together, and repairing such faults usually requires replacement parts.

(5) Jumper and the fault caused by setting

Jumper and settings caused by the fault is due to the adjustment of the device's jumper switch, so that the equipment's operating parameters have changed, so that the device does not work correctly, such as the motherboard in the CPU operating frequency, resulting in CPU overclocking and can not work properly.

(6) The fault caused by the power supply

The fault caused by power supply is due to the shortage of power supply voltage, low power supply or power failure. This failure usually results in a failure to boot and the computer is constantly rebooting, and repairing such a failure typically requires a power supply replacement.
