For motherboard repairing, it is necessary that you must first understand what are its main parts. It is located inside the computer cabinet, and consists of a microprocessor, chipset and BIOS (basic input output system). The microprocessor decides the type of central processing unit (CPU), i.e., the cabinet type. The chipset of the computer motherboard constitutes two bridges: north bridge and south bridge. These bridges control the flow of data to the computer. The basic functioning of the computer is controlled by the computer BIOS. A real-time clock is also another major component of the motherboard. The slots and ports on it connect the computer peripherals like the sound card or graphics card. These slots provide a connection between the hard disk and the computer peripherals.
