  • If the CPU wants data from RAM or the graphics card, it gets it via the Northbridge <br /> The Southbridge chip controls PCI and EIDE devices as well as ISA <br /> In the Athlon 64, the address bus is 64 bit <br />
  • Burn-in failure is where a board dies due to a manufacturing defect – usually happens in first 30 days of use <br /> Can damage motherboard with static – always wear anti-static strap <br /> Intermittant faults= PC reboots itself, blue screen of death, example of Kate’s PC <br /> Determining that the motherboard is faulty is often after establishing that every other component is working properly <br />
  • These are the main motherboard manufacturers <br />

  • MOTHERBOARDS Jazz
  • 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 478 P-III: PGA 370 P-II: SLOT 1 P-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
  • FULL DIAGRAM OF MOTHERBOARD
  • TYPES OF MOTHERBOARD MOTHERBOARD INTEGRATED MOTHERBOARD NON INTERGRATED MOTHERBOARD
  • 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
  • How it all connects together backside bus L2 Cache Pentium CPU (in the CPU housing – on die) 32 bit address bus 64 bit data bus North Bridge RAM frontside bus L1 cache (Memory Controller) memory bus AGP AGP bus HDD scanner EIDE CD/DVD PCI South Bridge PCI bus sound ISA bus keyboard mouse FDD ISA modem BIOS
  • 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
  • Buying a motherboard     Intel or AMD processor Asus, Abit, Gigabyte, Tyan, Shuttle ATX case and ATX power supply Clock speed
