Personal Computer Disassembly

1. Prepare all your tools. Before starting computer disassembly, make sure you have
prepared already the tools you need and be sure to have a container for keeping the
screws and small computer parts. Having a container will avoid screws from mixing
and a much organize parts.

Figure 1: Tools for the PC disassembly and assembly

2. Unplugging - The first thing you do is to unplug the computer from the power
source then every cable that is plugged in to your computer. That includes the
cables such as the mouse and keyboard.

Now that your computer is fully unplugged, move your PC to a clean work space,
preferably on top of a table.
3. Wear your PPE. Wear your anti-static equipment or tools to avoid ESD damage to
your computer. In the absence of the anti-static devices you can touch the unpainted
part of the system unit with your bare hands to remove the ESD of your body.

4. Open the Outer Shell/Case. Remove the screws of the side cover opposite to the
side where the ports are.

Once the screws are removed, you can remove the side panels. On most
computers, they just slide off. Start with the left side panel (the side that once had
the knobs), slide it towards the bac k of the computer. Now you can remove the left
panel. Just like the other side, slide it towards the back of the computer.

Once the side cover is removed, turn your system side down where the opened side
of the system unit should be facing upward where you can comfortably look down on
the inside of your system case
5. Remove the Power Supply – To be able to remove the power supply, is unplug
every power connector (Molex, ATX power connector, berg, etc.) Once everything is
removed, unscrew the four screws holding the power supply in place, on the back of
the computer. Next, push the power supply from the outside, and then lift it out.

Figure 4. Unscrew the power supply

6. Remove the data cables. With the power supply removed, the data cable should be
removed next. This include the IDE cables, SATA cables and other drive cables.

7. Remove adapter card and RAM. To remove the RAM, push down on both tabs
holding the RAM in place, which are located at both ends of the RAM. To remove
adapter card, begin by removing the backplane cover and remove the screw that
secures the cover and the card.
 Figure 6. Removing the Memory and adapter cards

8. Remove all drives. This include your hard drive, optical drives and other drives.

a. CD/ DVD Drive(s)- First, unplug the ribbon from the back of the drive. Once that is
completed, pull on the tab securing the drive in place, then push it out from the
inside.

b. Hard Drive - First, unplug the connector at the back of the slot, and unplug the other
end from the motherboard. Also unplug the SATA cable from the motherboard and
the hard drive. The portable hard drive slot is secured the same way the CD/DVD
drive is, with a tab. Pull on the tab, then slide the slot out.
` To remove the hard drive from the side of the slot, unscrew the four screws securing
it in place. You must be very careful not to drop the hard drive, since it is very
delicate!

Figure 8. Removing the hard drive from the side of the slot

9. Remove the front panel connectors. Before removing the front panel
connections, document the position of the connectors, this will include the USB,
Front panel and audio headers.

10. Remove the Motherboard - To remove the motherboard locate first all the screws
and lightly unscrew all screws alternately. The motherboard has seven screws
holding it to the frame, which are indicated by large white circles around them.
Remove them and then lift the motherboard out of the frame.
 Figure 10 Removing the Motherboard

11. Clean the system unit. Clean the system unit chassis with your brush or using
portable vacuum cleaner, also clean your motherboard and the rest of the
peripherals.

Personal Computer Assembly

1. Prepare your workplace

a. Take Inventory:

Before you start, take an inventory of your parts. Do not begin assembling
your computer if you don't have everything you need. Begin the step-by-step
process once you are ready with everything you need.
 Figure 12. Take inventory of the Different Computer Parts

b. Make Space, Make Time:

Building a PC takes up space - about a dining room table worth. So make

sure you have plenty of working room and a few hours to proceed with minimal
interruption. Work on a flat, stable table top surface, or bare floor, where you
have room to layout all of the items.

c. Prepare Grounding Protection:

Use an inexpensive antistatic wrist strap. It is the perfect preventive

measure if you have no alternative to working on carpet. Remember, a table top
or bare floor is always the best place to build your system. Make sure you are
wearing your antistatic wrist strap correctly (it does you no good at all if you do
not wear it!), and you are ready to proceed.

Figure 13. Wearing the Anti- static Wrist Strap Correctly

d. Have the Drivers Ready:

Assuming you have another internet connected PC, download the latest
drivers from the vendors' websites for each component you will be installing.
Sometimes drivers are updated between the time the component was
manufactured and the time you are installing it. It is always best to have the
latest. Copy them to a CD for easy access.

2. Prepare the Motherboard

a. Great care should be taken when installing the motherboard. First, take the board out
of its packaging and put it on top of the antistatic bag it came in.

Figure 14. Motherboard in an Antistatic Bag

b. Before you secure the motherboard onto the PC case/chassis, inspect it carefully for
any visible defects.

c. Next, review the motherboard manual, to make sure you are familiar with the mother
board layout and understand which socket is which. Manuals are extremely helpful,
usually easy to read, and include illustrations.

3. Install the CPU

1. Use the unlocking mechanism to open the CPU socket which is usually a lever.

2. Carefully line up the pins and place the chip in its socket; it will fit only when oriented
the proper way. An arrow or a missing pin on one corner of the chip will show you how
to line things up.

3. Align Triangular CPU and socket key marks.

4. Lower the lever to lock the CPU into place.

 4. Install the CPU Heat Sink

a. Follow the manufacturer's directions to install the heat sink and the fan that will cool
the processor. If you bought an OEM CPU and a separate heat sink, you may need
to spread a thin layer of the thermal grease that came with the heat sink over the
chip to ensure proper transfer of heat (some heat sinks come with this grease
already applied).

Figure 16. Install CPU Heat Sink

b. Attach the clip that holds the heat sink in place keeping in mind that it may require
a fair amount of force. Again, follow the instructions that came with the heat sink.
They will show you how to fit it correctly. If you are in doubt, you can visit the
manufacturer's website for more information.
 c. Plug the CPU fan's power connector into the proper connector on the
motherboard.

5. Install Memory (RAM Modules)

In order to install the memory modules, insert them into the proper sockets
and push down firmly but evenly until the clips on both sides of the socket pop into
place. If your motherboard supports dual-channel memory, consult the user manual to
determine which pairs of RAM sockets you should use. The motherboard and the CPU
are the brain and nerve center of your PC, so selecting these components is the most
important decision you'll make.

Figure 17. Install RAM Memory

6. Place the motherboard into the case

a. Check the layout of the sockets on the motherboard, and confirm that the ports
on your motherboard's back panel match the holes on the case's Input/Output
(I/O) shield that is installed in your case. If necessary, remove the old I/O shield
by tapping it firmly a few times with the butt-end of a screwdriver, and then
replace it with the shield that came with the new motherboard.
b. Carefully position the motherboard on top of the brass standoffs, line up all the
holes, and use the screws that accompanied the case to fasten down the
motherboard. If you are using a removable tray in your system, slide the tray and
motherboard back into the case and then secure the tray.

Figure 19. Mount the Motherboard

7. Connect the Front Panel Connectors.

a. Use your motherboard user manual and find the description about front-panel
connectors.
b. Attach each of the tiny leads from the power and reset switches, the hard-disk
activity lights, the PC speaker, and any front-panel USB and FireWire ports to the
corresponding pin on your motherboard. The needle-nose pliers are useful for
manipulating small pieces.
 Figure 20. Connect the different Leads

8. Install adapter cards (Graphics / Video Cards/LAN cards)

1. Begin by removing the backplane cover from the AGP or PCI Express X16 slot
(the metal piece where the monitor connector will emerge) (Figure 57).

Figure 21. Remove the backplane cover

2. Install the adapter card in the slot, (place card to the proper expansion slot) and
then secure the card with a screw.
 Figure 22. Installing the Graphics Board and other adapter cards

Note: Many motherboards have an onboard video card, LAN card or sound
card, sometimes adding expansion cards is not necessary.

9. Install Internal Drives

Now it is time to install your drives. This is an easy process, but it requires attention to
detail.

Figure 23. Attach your devices

10. Connect the data cables.

When the drives are installed connect the data cables. Parallel ATA drives
use wide, flat data cables that can be installed only in the correct way. Floppy drives
use a similar but smaller cable; SATA drives use a thin, 1cm-wide data cable. SATA
drives use a new type of power connector that many power supplies don't come with.
Fortunately, many motherboards ship with adapters for converting a standard four-pin
power connector to a SATA power connector (Figure 59).
 Figure 21: Connecting the data cables

NOTE

You are going to be doing work that requires attention to detail and can be quite
frustrating if you do not go into it with the right attitude.

11.Connect the Power Supply

Making the proper connections is crucial to successfully assembling your PC system.

Fortunately, manufacturers provide color-coded power cables and unique connector
shapes to make the job easy.

a. First, plug the large ATX power connector from your power supply into the
matching port on your motherboard. Look Figure X for details.
b. Locate the smaller, square processor power connector and attach it to the
motherboard. Note: your connector is usually located near the processor. As
always, refer to your motherboard's manual for the exact locations.

12. Take final inspection. Take a final check on connections and wires before closing
the system unit cover and before connecting computer peripherals.
