Easy Steps to Assemble a Computer

Assembling a computer involves connecting internal and external components. Internal components include the ones that are installed inside a system case such as motherboard, RAM, Disk drives, SMPS and daughter cards. External components are devices that are attached to the system case, such as mouse, keyboard, scanner & printer.

Assembling a PC:

cpuThere are certain key components that you need to consider when assembling a computer. Depending on the requirements of the user, the components vary. The components that are required while assembling a computer are:

  1. Hard drive.
  2. Memory modules (RAM)
  3. Power supply (SMPS)
  4. Heat sink
  5. Fan
  6. IDE cables
  7. DVD writer
  8. Graphics card
  9. Monitor
  10. Keyboard & Mouse

Best practices while assembling a computer.

  1. Keep a static-sensitive device, such as anti-static wrist strap, to disperse static electricity.
  2. Disconnect the unit completely before starting to work with the system case.
  3. Use an air duster to blow the dust from the system case.
  4. Make use of the plastic ties to tie loose cabling inside the system case.
  5. Use a small torch to see the connections in the system case.
  6. Make note of all the important settings on as sheet of paper.

Hands on exercise:

  1. The first step in assembling a computer involves opening the system case.
  2. Turn the knob present on the side of the case and then slide out the lid. Some system cases have two covers, the right and left cover, which you need to remove. You have to unscrew the required screws in order to remove the covers.
  3. Match the new power supply unit with the image of the power supply unit shown in the manual and then start the installation.
  4. Search the location of the power supply unit in the system case.
  5. Insert the power supply unit in the system case. Align the screw holes of the system case with the screw holes of the power supply unit. Fix the screws of the system case with the screws of the power supply unit.
  6. Place the system cooling fan below the power supply box. Fasten the screws to attach the fan from outside the system case.

Installing the Microprocessor:

  1. Check the voltage requirements from the Motherboard and the Microprocessor documentation.
  2. Wear an anti-static wristband.
  3. Place the Motherboard on the work desk.
  4. Take the Microprocessor out from the anti-static bag by holding the microprocessor at the edges.
  5. Check that all the pins on the underside of the microprocessor are straight.
  6. Locate the socket where the microprocessor must be installed. Raise the lever and flap. Align the notch on the microprocessor with the alignment notch on the motherboard.
  7. Gently, place the microprocessor in the socket.
  8. Press the microprocessor firmly in the socket keeping in mind that no damage is caused to the pins.
  9. Push the lever back down such that it is parallel to the motherboard and locked in place, taking care not to break the lever while lowering it.
  10. Install CPU fan on the microprocessor and connect the fan cable to the CPU fan socket on the motherboard.

Installing the Motherboard:

  1. Attach the ATX plate on the rear of the system case. Ensure that the ports for mouse and keyboard are towards the power supply of the system. Align the plate in the appropriate place by pressing the plate from inside of the cabinet.
  2. Install the standoffs on the system board tray of the cabinet in the appropriate location. The standoffs that come with the motherboard may be of different varieties and must be positioned carefully, so that they are not interchanged.
  3. Place the motherboard on the system board tray of the cabinet after fixing the standoffs. All the standoffs must be visible through the holes in the motherboard.
  4. Attach the motherboard to the drive bay by fixing the different screws. Start with the centremost screw and work outwards in a star pattern. You must not tighten the screws too much, as this will damage or crack the motherboard.
  5. From the system case find the different connectors such as the Hard drive LED, speakers and reset connectors. You can read the instructions from the motherboard manual and follow them.
  6. Fix the power connector from the power supply to the motherboard. Attach the 4 pin connector CPU fan on the motherboard.

Installing the memory

  1. Wear the anti-static wristband or hold a metal part of the chassis before touching any of the system components.
  2. Hold the RAM module by the ends without touching pins or chips. Insert the module straight so that it is perpendicular to the motherboard.
  3. Close the side clips on the RAM and lock the clips.

 Mounting the Hard disk:

  1. Locate the empty drive bay in the system case. Insert the Hard disk into the drive bay and attach screws to hold it in place.
  2. Connect one end of the signal cable to the motherboard and other end of the signal cable to the Hard disk. Signal cable is the SATA cable used to transfer data from hard disk to motherboard and vice versa.
  3. Connect the power cable to the Hard disk. Fix the screws to attach the hard disk to the bay.

Mounting the DVD-writer:

  1. Remove the plastic panel from the system case. Insert the DVD writer in the system case.
  2. Attach screws to fix the DVD writer to the system case. Connect the SATA cable to the DVD writer and other end of the SATA cable to the motherboard.
  3. Connect the power cable to the DVD writer.

Connecting External peripheral:

  1. Connect the Monitor to the VGA port of the computer at the rear end of the cabinet.
  2. If you have a DVI port on the motherboard and a DVI monitor than connect the monitor to the DVI port of the motherboard.
  3. Connect the USB keyboard on the USB connector and the USB mouse on a separate USB connector.
  4. Connect the power cord to the SMPS unit at the rear end of the cabinet. The end of the power cord should be inserted into the wall socket.
  5. Connect the monitor power cord to the monitor and the other end to the wall socket.

Now you can safely power ON your computer.
