Procedure
Step 1: Assembling of Hardware Parts

First you will need to assemble the parts necessary to build the Computer.

The parts we will use are listed below:

  1. Motherboard (sata capable)
  2. Computer Case
  3. Optical Drive (DVD rw and sata capable)
  4. Memory (RAM)
  5. Power Supply
  6. Sata Cables
  7. Processor (CPU)
  8. Processor Fan
  9. Case Fan
  10. Hard Drive (Sata Capable)



Step 2: Gather Tools and Supplies

Gather the tools you will need for the project:

  1. Screwdriver (for slotted and phillips head screws)
  2. Wire cutters and strippers
  3. Needle-nosed pliers
  4. Utility knife
  5. Small flashlight
  6. Adjustable wrench
  7. Small container to hold screws
  8. Heat sink compound
  9. Grounding strap.



Step 3: Open the Case

Open the computer case by removing the side panels.

Find the screws that hold the side panels in place and remove them (shown in figure 3 circled in red). The panel is removed by first sliding it back (figure 4) then lifting it away from the case



Step 4: prepare the case for assembly & ground yourself

Three things need to be done before assembly begins:
  1. Remove any parts or packaging materials that may have been shipped inside the case
  2. Remove the cover for the optical drive.
  3. Make note of the cables pre-installed in the case. These should be front panel connections for features such as the power switch, audio jacks and usb ports. If they are not labeled, consult the manufacturer’s documentation and label them yourself nowbefore other parts are installed in the case. now put the grounding strap on your wrist (figure 10) and connect the other end to the computer case. If your strap is not equipped with a clip to hook to the case, find a place to wedge against the metal as shown in below figure 11. This will prevent any buildup of static electricity on your body from damaging the computer components.


caution:static electricity can ruin computer components. Always wear a grounding strap when handling any internal components.



Step 5: Installation of Motherboard

  1. Install the i/o bezel plate into the opening in the back of the case (figure 14). It pushes in from the inside.
  2. I/o bezel is a trim panel installed in the back of the case that follow these steps to install the motherboard in the case:
  3. Install standoffs in the case. The standoffs screw into the motherboard mounting holes shown in figure 14. Check the screw hole locations on the motherboard for exact placement.
  4. Lower the motherboard into the case and align with the i/o bezel.
  5. Install the screws.

Figure 15 shows the motherboard installed in the case. It works best to leave the screws loose until all of them have been started and the board is aligned with the bezel.



Caution: to prevent damage to the motherboard it must only contact the standoffs and screws. All of the standoffs and screws must be installed.


Step 6: installation of hard drive

The hard drive is the device that stores all of your data. It is 3.5" wide and needs to be mounted so that you can gain access to the cable connections on the back (figure 16). If that is not possible you may need to connect cables before you install the drive. To mount the drive:

  1. Find a 3.5" drive bay to install the drive in. If you have trouble finding a place to mount the drive consult your case documentation for suggestions.
  2. Slide the drive into place until the screw holes on the sides are lined up with the holes in the case.
  3. Install the screws.



Step 7: install optical drive

The optical drive is 5.25" wide and is installed in the drive bay that we removed the cover from in a previous step. Cable access considerations apply to this drive also. To install the drive:
  1. Slide the drive into the drive bay until the screw holes are lined up and the front of the drive is flush with the front of the case (figure 18). Make sure that it is orientated correctly.
  2. Install the screws.


Step 8: install the cpu

The cpu is the brain of the computer. It is installed on the motherboard in the socket shown in figure 20.to install the cpu:

  1. Find the corner marking that designates pin 1 of the cpu as shown in figure 19. On this amd brand processor, the corner is marked with an arrow. Consult the manufacturer's documentation for specific information about your processor.
  2. Lift the small metal rod next to the socket as shown in figure 20.
  3. Find the corresponding marking on the cpu socket and insert the cpu so that the markings are lined up.
  4. Push the rod down to lock the processor in place (figure 21).


Step 9: install ram

The ram is the temporary memory location that the processor works from. Permanently stored data is pulled from disks and stored in ram while the processor works with it. The memory is easy to install:

  1. Set the ram board in the socket as shown in figure 22. Check to see that the notch in the board is in the correct location. If it is not, turn it around 180º.
  2. Press firmly on both ends of the board to set it into the socket. Make sure the tabs lock into place as shown in figure 23.


Caution: pressing the boards in when the tab is not aligned could cause damage to the ram boards as well as the motherboard.



Step 10: install the cpu fan

The cpu fan is really a combination of a heat sink and fan together. The unit draws heat away from the cpu. To install the fan:
  1. Place thermal compound to the cpu following the instructions provided with the compound.
  2. Set the fan assembly on the cpu with mounting tabs aligned.
  3. Pull the locking rod down on the fan assembly to lock into place.
  4. Connect the fan assembly's power connector to the motherboard. Consult the manual to determine proper placement.

Caution: failure to apply thermal compound will result in insufficient cooling and will cause damage to the cpu and/or motherboard.



Step 11: Install case fan

The case fan is usually installed on the back panel of the case. If the fan mount is not obvious consult the case documentation. To mount the fan:

  1. Align the mounting holes by holding the fan to the mounting pad on the inside of the case as shown in figure 25. The fan needs to be mounted so that it blows air out of the case.
  2. Insert the screws from the outside of the case and tighten.


Step 12: install power supply

To install the power supply:

  1. Align the mounting holes in the case and power supply as shown in figure 26.
  2. Insert screws and tighten.


Step 13: connect cables


With all of the components installed in the case, follow the motherboard manual in order to make sure proper connections are made. There are two kinds of connections, power and data.

every device that has been installed needs power. In figure 27, the power supply connectors are shown. The motherboard has two power connections, and there are two connectors specifically for sata devices (drives). The other connectors will run fans and other non-sata devices.

  1. Data cables connect drives and front panel devices to the motherboard.


Step 14: wrap-up


Now that the components are completely installed, the last thing to do is to reinstall the side panels on the case. The computer is now ready to be turned on and to have software loaded on it. If the computer has problems starting up, check all component connections and mounting to make sure that you have connected everything up correctly.


Step 15: connecting input/output and peripheral devices with cpu

Peripheral devices: the input / output organization of computer depends upon the size of computer and the peripherals connected to it. The i/o subsystem of the computer, provides an efficient mode of communication between the central system and the outside environment.
the most common input output devices are:

  1. Monitor
  2. Keyboard
  3. Mouse
  4. Printer
Monitor

To connect the monitor with the system you need to connect the "vga" cable in the vga port of the monitor and other end to the system as shownin figure 1.
If you're using an hdmi and dvi cable, you'll have to first plug the dvi cable into your computer. Then attach one end of the hdmi cable to the dvi cable. Then plug the other end of the hdmi cable into your monitor.



Keyboard

There are two types of keyboard mainly used

  1. ps/2 keyboard
  2. usb/wireless keyboard
To connect ps/2 keyboard
  1. Connect the keyboard to the ps/2 port on the back of the computer.

When looking at the back of the computer, you'll notice two ps/2 ports next to each other. Verify you're connecting the keyboard to the purple connection, as shown in the picture below.

  1. To connect the usb keyboard to the usb ports on the back or front of your computer. If you're using a usb hub, it can also connect to the hub. However, we recommend a direct connection to the back of the computer if possible.if you have a laptop computer, an external keyboard can also connect to one of the usb ports. If no usb ports are available, a usb hub would be needed.after the keyboard is connected, it should automatically be detected and installed. If the keyboard has any special features, you need to install the keyboard software and drivers.



Mouse

There are three types of mouse mainly used
  1. ps/2 mouse
  2. usb/wireless keyboard
  3. bluetooth mouse
