What are the circuits of MOTHERBOARD and what is their work
Motherboard and chips) MOTHERBOARD is an important part of the computer. Motherboards are a flat board. On which many circuits are made There are lots of smd components installed on this. When any of these components stop working. So the mother board does not work properly. Inside the board, these bad components are found and replaced. This board is called Repairing. So that the board seems to work again.
But finding a bad circuit or a component is not easy, you need to know the working step of that device.
I will try to tell all the problems that are on the board and what is the work of their work, if they do not work, I hope that you will not have any problem in understanding. If you have any talk or topic If you do not understand, you can ask and comment.
Motherboard circuit detail
The work of this circuit is to give core voltage to the micro processor. By
filtering and boosting the supply from SMPS, gives core volts according to Cpu. If this circuit does not work then the following written errors will occur.
What is VRM circuit in
motherboard
VRM section on Motherboard VRM Section or circuit
If all of these VRM does not work right then the computer will have trouble.
. Clock ic and 14.318 MHz crystals are used in the clock circuit. Clock generator provides fsb to the micro processor on the switch by crystal only when the circuit receives approximately 2.5 v, 3.3 v obtained from the circuit vrm. Thereby providing clock pulse according to the receipt signal from cpu or by other departments according to them.
Clock Generator Circuit Faults
If this circuit does not work then the following written problem will occur.

Reset signal will not be available from CPU. If there is no reset signals then the display will not be displayed in the mother board.
No display problem
This circuit connects the display with cpu.
In simple language, this circuit has a RAM Controller display controller, through which cpu contacts other digital components. This is called North Bridge. These chips are located near the cpu.
The bridges are of two types.

Motherboard circuit detail
Separate circuits have been made to do any work in the mother board. I am writing down the circuit
1.VRM-Voltage REGULATE MODULATION
The work of this circuit is to give core voltage to the micro processor. By
filtering and boosting the supply from SMPS, gives core volts according to Cpu. If this circuit does not work then the following written errors will occur.
- Cpu will not detect. Whether Cpu is detecting or not it touches the Cpu, if Cpu is not heating at all then it means cpu is not dectecting.
What is VRM circuit in
motherboard
VRM section on Motherboard VRM Section or circuit
- Cpu will be over heat.
- The system will hang.
- Computer restart
- The computer will not start.
- Cpu Fen Close
If all of these VRM does not work right then the computer will have trouble.
2. CLOCK GENERATOR
The work of this circuit or department is to give a micro processor and other circuits according to their clock pulse, so that the digital circuit works. Clock ic and 14.318 MHz crystals are used in the clock circuit. Clock generator provides fsb to the micro processor on the switch by crystal only when the circuit receives approximately 2.5 v, 3.3 v obtained from the circuit vrm. Thereby providing clock pulse according to the receipt signal from cpu or by other departments according to them.

3. MCH-North Bridge
This circuit is made inside a BGA IC. Exchanging the work data of this circuit. It converts information from South Bridge to cpu and cpu information to the South Bridge. Simultaneously, the system works to connect cpu to RAM, by controlling the RAM.This circuit connects the display with cpu.
In simple language, this circuit has a RAM Controller display controller, through which cpu contacts other digital components. This is called North Bridge. These chips are located near the cpu.
The bridges are of two types.
