PC Assembling

The following steps give as overview of assembling a computer.

  • Components of a computer.
  • Motherboard
  • Processor
  • PrimaryStorageDevices



  • SecondaryStorageDevices



  • SMPS(SwitchedModePowerSupply)
  • InputDevices



  • OutputDevices


  • Processors
  • Components on the motherboard:
  • Processorslot/socket
  • MemorySlots
  • ExpansionSlots
  • I/OPorts
  • Chipsets
  • IDE/SATAConnectors
  • CMOSBattery
  • Power Supply connector
  • HeatSink
  • Front Panel Connectors

Having collected all the components for the system, one can now get down to actually assembling the computer together.

Step 1

Open the system casing

Step 2

Remove the back plate of the casing for mounting the motherboard

Step 3

Align the motherboard with the mounting screws provided and see that the motherboard is fastened at all four corners and at least two places within the motherboard.

This will keep the motherboard stable and provide a good foundation for the rest of the system’s cards.

Step 4

Mount the processor on the motherboard.

Remember to check any jumpers that you may have to set to configure the motherboard to the processor you have. These settings are indicated in the manual that accompanies the motherboard.

Caution : Remember to attach the connector for the CPU fan to the appropriate point on the motherboard. Failing to do so would result in your processor overheating and could even result in permanent damage.

Step 5

Mount the RAM.

The RAM goes into the slots in only one direction so remember to align the notches on the RAM to those on the slot.

Step 6

Mount the motherboard and backplate in the system casing.

Step 7

Mount the CD/DVD drive.

Step 8

Mount the hard disk drive.

Step 9

Connect the power cables to the motherboard.

If you have an ATX power supply, the connectors will only fit into the motherboard in one direction. Align the connector so that the clip on the connector fits into the one on the power connector on the motherboard socket.


Step 10

Attach the front panel connectors to the motherboard

The indications for attaching the front panel connectors to the motherboard are shown in the motherboard manual.


Step 11

Connect the primary IDE channel to the hard disk.

The master IDE channel is indicated on the motherboard. Look out for an indication that reads “Pri. Master” or “IDE 0” on the motherboard.


Step 12

Attach the power connector to the hard disk.

Step 13

Connect the secondary IDE channel to the CD/DVD drive.

By connecting the CD/DVD drive to a separate IDE channel as a master drive, the efficiency of accessing the IDE devices will be much higher than connecting the CD/DVD drive as a slave to the same channel as the hard disk.


 Step 14

Attach the power connector to the CD/DVD drive.

Step 15

Connect the display card.

Caution : Remember to handle the card by its edges so as to prevent damage due to static charge.

Insert the card by first aligning the connectors to the socket on the motherboard. Then slide in the card by gently rocking it back and forth so as to ease it into the slot. Do not try to force the card into the slot. See that the card is firmly seated in the slot before fastening the screw.


 Step 16

Mount the sound card.

Note: This is necessary only if you are using a motherboard that does not have any integrated sound card.


Step 17

Connect the monitor’s power cord to the monitor.

Depending upon the type of power supply your cabinet has, the monitor’s power cord could be either connected to the mains power supply or to a connector on the SMPS near the main power connector of the computer.


Step 18

Check all connections and cards.

You are now nearly ready to power up your system. Before doing so, now’s a good time to check all the connections and cards in your system. Glance over all the connectors to the drives and cards and see that they are securely attached with no loose contacts anywhere.


Step 19

Connect the keyboard.


Step 20

Connect the mouse.


Step 21

Close the system casing.

Step 22

Connect the power cord to the power supply.

Caution : Remember to verify that the power point that you are connecting your computer to is properly earthed.


Step 23

Switch on the power to the system.

Probably the most apprehensive part of building the computer, now’s the time to power up the system. Switch on the mains power and hit the power button on the casing. You should hear the hard disk spinning up and the motherboard should emit a single “beep” signalling that all systems are functional. See that the CPU fan and the power supply is running.


Step 24

Congrats!! Now you are ready with your computer working.                                     The last step is install the operating system.

With all the hardware properly set up, you are now ready to load the operating system. Load the operating system and verify that the system is functioning correctly and only then connect peripherals like the printer and scanner etc.
