INTRODUCTION TO MOTHERBOARD

WHAT IS MOTHERBOARD ? Motherboard is called as a

Headquarter of the system. Motherboard is referred to as the

Longest Printed Circuit Board of the System (PCB)

Motherboard is used to attach all the components and pass the instruction between the components to create the process inside the system.

IDENTIFICATION OF MOTHERBOARD

Motherboard is identified by its CPU socket number and available components

Some of the Identification are P-IV: PGA 478P-III: PGA 370P-II: SLOT 1P-I: SOCKET 7

WHAT DOES MOTHERBOARD HAS

MOTHERBOARD

PORTS SLOTS CONNECTORS

MOTHERBOARD…

MOTHERBOARD HAS 3 Major Division consisting of

PORTS SLOTS CONNECTORS

PORTS

PORTS is called as IN and OUT point of the system.

Basically the Ports on Motherboard are responsible for IN and OUT operations of the system.

There are various types of PORTS available at the Back Panel of the system

Types of Ports…..

SLOTS & CONNECTORS

SLOTS and CONNECTORS are available on board which is used to connect the Internal devices in the system.

SLOTS are used to connect various Cards while CONNECTORS are used to connect various Internal Devices

There are various type of SLOTS and CONNECTORS available On-Board

Types of SLOTS & CONNECTORS

OTHER OBJECT ON BOARD

NORTH BRIDGE SOUTH BRIDGE BIOS CHIP

OTHER OBJECT ON BOARD

NORTH BRIDGE: It is a chip which is closer to the CPU. It is responsible for handling the communication between the RAM and Processor

SOUTH BRIDGE: It is a chip which is closer to the I/O Slots. It is responsible for handling the communication between I/O port & RAM

BIOS CHIP: It maintains the System Setting

INTEGRATED MOTHERBOARD

INTEGRATED MOTHERBOARD

Integrated Motherboard is a board which has everything In-built.

In these type of Motherboard all are on-board and does not require any kind of Cards

Some of the On-board things are DISPLAY,LAN,SOUND,MODEM,USB

NON-INTEGRATED MOTHERBOARD

NON-INTEGRATED MOTHERBOARD

Non-Integrated Motherboard is a board which has no Ports available.

These type of Motherboards require various kind of Cards to do input output operations

Some of the Cards available are are DISPLAY Card, LAN Card, SOUND Card, Internal MODEM,USB Card

BUSES

BUSES are referred as the carrier of signals which are responsible for carrying the signals from one location to the other on the motherboard.

There are various type of BUSES available like ADDRESS BUS,DATA BUS,SYSTEM BUS

Troubleshooting Motherboards

Burn-in failure PC won’t boot Incorrectly seated RAM Incorrectly seated Graphics Card Power surges ESD Intermittant faults
