  MOTHERBOARD a crucial parts of the computer. If the motherboard is a flat board. Which consists of several circuit. This lot consists smd component. If none of these component stop working. Even if the motherboard does not work correctly. Board component inside these poor are identified and replaced. Repairing the board that are called. If the board seems to be working again. 

Bad circuit or component is not easy to find but you need to be aware of that device must have a working step. 

Board - Which are the circuit. What are and how they work. Their job is not what the problem is. I will try to explain it all. I hope, you will have no trouble understanding. If you do not understand a thing or topic, you can ask and comment.

 Motherboard circuit detail  

Inside are all the work of the motherboard. Different to those circuits are created. I am writing down the circuit.

1.VRM-VOLTAGE REGULATE MODULATION 

Micro processor core voltage to the circuit would work. Cpu by boosting the supply from SMPS filter and allows the Core Voltage.
If the circuit does not work. Reports arrive the following faults.
* Cpu will not detect. 
Cpu is to detect. Or not, as it turns out Cpu touching. Cpu If you are not hot at all. So that means, cpu dectect are not.

VRM Section or circuit

* Cpu Heat will be over. 

  * The system will hang. 

* Computer to be restarted. 
  
* The computer will not start. 

  * Cpu fan to close some running.

  if VRM' is not work properly  in the computer, it all comes trouble.

2. CLOCK GENERATOR

The micro-processor circuit or work department and the clock pulses would give them to other circuits. He works in the digital circuit.
And 14.318 MHz crystal clock ic clock circuits are used. Clock generator circuit from vrm approximately 2.5 v, 3.3 v only by receiving the crystal provides micro-processor fsb. On receiving a reset signal from the cpu clock pulses according to their will or other departments.

Clock Generator Circuit Faults

If it does not, then the following will cause the circuit.

clock generator section or circuit

* Cpu will not reset the reset signal, no signal will not display on the motherboard. 
* No display problem

3. MCH-NORTH BRIDGE

The circuit is made up of a BGA IC inside. The circuit work to exchange data. Information received from the South Bridge to the cpu and cpu Information provided by the South Bridge that delivers. With this control system RAM cpu and adding RAM to work with.
The circuit is connected to the display with cpu.
In this circuit in simple language spoken by its cpu RAM controller has a display controller provides connectivity to other digital component. It is called the North Bridge. It is engaged in the vicinity of the cpu chip.
There are three types of North Bridge.

MCH-NORTH BRIDGE CONTROLAR

4. ICH-INPUT OUTPUT CONTROL HUB/SOUTH BRIDGE/PIIX
5. I/O CONTROLLER
6. BIOS
7. AUDIO CONTROLLER
