Assembling PC

WHAT IS IT ?

  • Here we are going to remove all the parts of a computer.

  • And assemble the parts together.

  • A basic computer has some basic parts we are going to open such as:

  • CPU

  • Monitor

  • Speaker

  • Keyboard

  • Mouse

  • So here we need some tools like Screw Driver to remove all the parts of CPU.

CPU (Control Processing Unit)

  • CPU is the most important part a computer system.

  • We are going to open the CPU apart and discuss every part of it.

  • This below picture is a running CPU.

  • After opening the metal cover from the left side of the CPU, we can see all the small component connected to the motherboard.

  • Take all the components out of the cabinet.

  • Remove all the connection from the motherboard.

  • It looks like as below picture.

  • We will discuss the small components here.

  • Remove all the connection from the motherboard.

  • It looks like as below picture.

  • We will discuss the small components here.

  • Connect the 20 or 24 pin ATX connector and the 4-pin power supply control connector to the motherboard.

  • Ther are 2 types of connectors you will find.

  • SATA connectors are the data cables, which will connect to Hard Drive, optical drive and external drive.

  • One end plugs into a port on the motherboard.

  • Power Cable, we will get from SMPS.

  • This cable connects to the extenal devices and to motherboard.

SATA Connectors

Power Connector

  • SMPS provides all the power supply to the the board.

  • There are different types of connectors and different colors of wire are present.

  • Different color of wires carry different voltages.

  • It provides 3.3v, 5v, 12v and more.

  • Here is the back pannel connector port.

  • PS/2 port is for mouse and Keyboard.

  • 3 paralel ports are form printer, display and projector.

  • One LAN port is there for ethernet connection with 4 USB port.

  • For audio section 2 input and 1 output port are present.

  • Green audio port: computer speakers or headphones.

  • Pink audio port: microphone.

  • Blue audio port: MP3 player, CD player, DVD player, turntable, electric guitar etc .

  • Disconnect the Hard disk from the power supply and the motherboard.

  • Here all the data including OS are being stored.

Power port

  • Mount the DVD-ROM drive.

  • It is used to reading or writing data to or from optical discs. 

  • After connecting the ATA cable to the device, hook it up to the power supply.

  • Here is a extenal DVD drive, which can be connectd through USB.

  • It can be used as reading and writing from a optical disc.

  • Put out RAM form the moterboard.

  • RAM is a volatile memory and requires power to keep the data accessible.

  • If the computer is turned off, all data contained in RAM is lost.

  • Here we have 2 RAMs with front and back view.

  • A heat sink with cooling fan is mounted above a processor.

  • Cooling fans are necessary to aid in cooling the system.

  • Without them, the CPU would overheat and cease functioning.

  • The central processing unit (CPU), also called a processor, is located inside the computer case on the motherboard.

  • It is sometimes called the brain of the computer, and its job is to carry out commands.

  • Here the processor is taken out from the socket.

  • Assemble all the parts back to the original to make it work.

  • Connect the power supply from SMPS:

  • 4 pin for motherboard

  • 20 pin for motherboard

  • 4 pin for Hard Disk Drive

  • 4 pin for Optical drive.

  • Connect the SATA cable from motherboard to Hard Disk Drive and Optical Drive for data flow.

  • And connect  the power supply and IO devices to CPU.
