How to assemble a Desktop Computer

In assembling a desktop computer you must first gather all the components which would be needed which include components for the case, mother board, the processor/CPU, RAM, power supply, hard drive, Optical drive, Video card/ graphics/ GPU, and peripherals. Next the tools that would be needed to complete the job are a Philips-head screw driver, needle nose pliers, Anti-Static wrist strap, a large working space, ground mat, spring action parts grabber, electrical tape, and a flashlight.


  • The first step is to find the standoffs that should have come with the case.
  • Then remove the I/O shield from the back of the case, where the ports on the back of the motherboard will fit. Then after they have been placed, put in the I/O shield which came with the motherboard.
  • Next is to match the pattern of the screw holes on the case to the pattern of the holes in the on the motherboard. A standoff has to be placed in each hole on the tray and position the motherboard so that the holes can be seen through the holes the screw holes in the motherboard. The metal tabs in the case are supposed to touch the metal tabs of the connections on the back of the motherboard and ground them. Bending may have to take place which bring the needle nose pliers into action
  • Last step is to fasten the screws into the standoffs, they should be snug not tight.

  • First thing that has to be done is to unlock the CPU socket by just push it out and then pull it up a small plastic or metal arm that lies on the side of the CPU socket.
  • Next is to align the CPU to the socket. One corner will have a diagonal section without any pin that is different from the others find the corresponding corner on the motherboard's CPU socket and gently lower the CPU into the socket.
  • Then it is just to lower and lock the socket arm, which in turn will lock your CPU into your motherboard.
  • Installing the Heatsink/Fan

  • The mounting hooks on the sides of your CPU socket have to be matched with the clamps on the sides of the heatsink.
  • Lower the heatsink onto the CPU.
  • Hook the heatsink to the socket, and then pull the locking arm until it snaps into place.
  • After the heatsink is locked securely in place, you the fan's power need to attach to connector to the motherboard's fan header.

  • Locate the RAM slot on the motherboard and push the levers on the sides of the DIMM socket.
  • Then place the RAM module inside the socket, lining up the notches on the module with the bump on the socket.
  • Next push down on the RAM module not too hard but just right so that the levers move into the notches on the sides of the RAM chip, making sure that the module is level and that one side is not high than the next.

  • Place the power supply at the top of the case where the slot for it is then place the screws to secure it in place.
  • Next connect the power supply to the motherboard, and the heatsink fan.
  • Make sure all connections are good and secure, also make sure it is screw in fine.


In this part a choice has to be made between IDE Hard drives and SATA Hard drives. Seeing that IDE Hard drives are less established so setting the jumpers would not be called for as the SATA does not require it to be.

  • Slide the hard drive into the slot made available for it the first empty drive bay. Screw the drive into place, making sure the screws are not going in crooked.
  • Attach the cables to the hard drive and to the motherboard or controller card if necessary. There would be two cables, the ribbon cable (or SATA cable) and the power cable. The ribbon cable goes from the controller to the drive and the power connects to the power supply. On a SATA hard drive, position of the drives on the cable does not matter at all because a SATA cable only accommodates one drive.

    The use of an anti-static wristband will be needed because of the fact that we will be working with sensitive electrical equipment.

  • Locate an empty 5.25" bay and remove the front blanking panel from the case.
  • Next, slide the drive into the bay through the front of the case enough to allow it to fit the front plates or until it sits level with the front of the case.
  • Connectthe data cable to the drive and a free SATA port on the mother-board, then plug in a spare SATA power cable.
  • Secure the drive to the cage using the screws provided with your drive, ensuring a tight fit.
  • Next, plug in the sound cable from the sound card on the motherboard.

  • Locate the open slot for the graphics card on yourmotherboardand remove the small metal strip at the rear of the PC to make way for the rear-facing connectors on the new card.
  • Seat the card securely, and screw its bracket into place.
