9. Assemble and Disassemble: Defined
When referring to hardware, assemble is the act of
connecting together the different parts of a computer.
Disassemble is the process of breaking down a device into
separate parts to help determine a problem, to replace a part,
or take the parts and use them in another device or sell them
individually

11. Computer Assembly
The following are steps in assembling computer hardware.
Installing a
Motherboard
10 steps

12. 1. Remove the side panel. Before installing the
motherboard or any other components, we obviously need
to open up the case. Most cases have two or three screws
holding the side panel on while others just pop off. When
removing screws,
remember to put them
in a safe place so
we don’t lose them.

13. 2. Take a look inside. At the left side are pictures
of the inside of an average ATX case. Every case
has mount where you screw the motherboard on.
Feel free to find this

14. 3. Examine the motherboard. Make sure you are grounded
using an antistatic wrist strap. When handling a
motherboard or configuring the jumpers place the
motherboard on the static bag it came in. Don't sit it on the
carpet.

15. 4. Before you can continue, you need to set the jumpers
on your motherboard. The best way to explain this is
read your manual for proper terminology and
placement. Look for a
on setting jumpers.
Some
motherboard
are
jumperless
while others
are not.

16. 5.Every motherboard has holes for screws. We
have circled the holes to easily locate them.

17. 6. Remove all unnecessary metal plates. Pop out any
unnecessary temporary metal plates on the back of the
case so the motherboard can slide comfortably into place
as shown at the right side.

18. 7. After that is done, simply align the
screw holes with the mounts and insert the screws.

19. 8. Plug in case connectors (system light, power button, and
USB, if supported in case.) This step can be confusing at first.
Look for a big block of pins on your motherboard, usually
located at the bottom. Most boards label the pins, and most
cases label the connectors. So simply match up the
connectors with the appropriate pins.

20. 9. Plug in the power connector. Since the actual computer
is not plugged in, we can go ahead and plug the power
supply into the motherboard.

21. 10. Double check steps 4 and 8! Always double
check your work to ensure you haven't forgotten
anything

24. INSTALLING THE CPU
(STEPS)

25. 1. Put on an Anti-Static Wrist Strap. Attach it to your wrist and then
ground it to metal on the case. This isn't completely necessary but
highly recommended so you don't damage any hardware. The
slightest shock of static can easily damage components.
2. Locate the processor socket and lever.
Look on your motherboard and you
should see a socket similar to the one
in the image below.
This is where you will place the
processor. Attached is a lever
that locks the processor in place.
Lift the lever so it is vertical.
This will prepare us for the next few
steps.

26. 3. Locate placement arrow and check processor. Most processors have an
arrow or a cut corner. This simply tells you how and where to insert the
processor. Also look on the bottom of the processor to ensure no pins are
bent. If any are bent, contact the company and have the send you a new
one. Alternatively, you can use a screwdriver and carefully bend them
back, though this is not recommended.

27. 4. Install the processor. First, ensure the lever is lifted up or in the vertical
position. There is only one way the processor can be inserted so never force
it in, it should practically fall into place. Line the placement arrow closest to
the lever and drop it in. Slowly lower the lever until its all the way down. The
processor is now installed and locked in place.

28. B. Installing the CPU ( Write the correct sequence of installing a CPU) Write 1 –
4.

___3__ Locate placement arrow and check processor.
___4__ Install the processor.
___2__Locate the processor socket and lever.

30. Installing the Heatsink

31. 1. Locate the thermal pad or apply thermal gel. Under the heatsink there
should be a thermal pad. Simply pull away and remove the plastic film. In
some instances, there is no thermal pad so you need to apply a thermal
gel. Most heat sinks come with this so apply a little bit in the middle of the
processor where there is a raised area like in picture B.

32. 2. Place the heatsink on the processor. Never tilt the heat sink when
installing it. This could damage the processor. Picture A) shows the
incorrect way while picture B) shows the correct way to install the heat
sink.

33. 3. Heat Sink should not touch the
socket when fully attached.
4. Attach the clip to first plastic tab on socket.

34. 5. Line up second clip with tab and attach. Check to ensure the second
clip is aligned with the second plastic tab. Using a flathead screwdriver
and without applying pressure to heat sink, push down on the clip and
away so it can move past the tab then slightly push inward to attach.

35. 6. Plug in power lead. The power lead is usually located near the
processor. Please refer back to the motherboard user’s back to the
motherboard user’s manual for details on its location. Look for a
“Jumper and Connector Guide” section then look for a free fan connector
named “CPU Fan Power” or something similar.

36. Installing the RAM

40. Installing the Floppy
Disk Drive

41. 1. Remove the second side panel from the case. Using the same steps for
removing the first side panel to remove the second. This will enable you
to screw the components in on both sides so it’s more securely in place.
2. Remove the faceplate and insert drive into the floppy bay. On the
front of cases there are plastic plates. These just pop out, usually just
push it out from the inside. Slide the 3½” floppy drive into the floppy
bay as shown below.

43. 6. Hook it up to the Floppy Drive. Using the same FDD
cable, connect the other end to the back of the floppy drive.
Again, there should only be one way it can go in, but to
make sure it is installed properly, line up the red wire on
the FDD cable with Pin #1.

44. 7. Adding power. This is the easiest step. Grab an unused power cable,
preferably one with two leads on it. We recommend this since we can use
the
second lead for the hard drive in the next lesson. With the power lead in
hand, connect it to the back of the floppy drive. The power lead can only be
inserted

45. Installing the Hard Disk

46. 1. Set the Hard Drive Jumper. Open your hard drive user’s manual to the
jumper section and read it if you haven't already. If you only have one hard
drive, set the jumper to "Master" or "Single" depending on your brand of
hard drive. If you have two, set the one you are going to put an operating
system on to "Master" and the second to "Slave." NOTE: If you are using
more than one Hard Drive, its best to use the same IDE cable for both.
Note: Hard Drives generate a lot of heat so when installing
one, set it as far away from other components as possible.
Some cases still have hard drive bays near the power supply.
Power supplies generate a small magnetic field which can
damage or cause problems with your hard drive so avoid this

49. Installing CD-ROM
Drive

50. 1. Set the Jumper on the CD-ROM. Grab your CD-ROM user’s manual
to the jumper section and read it if you haven't already. If you only have
one CD-ROM, set the jumper to "Master" or "Single" depending on your
brand of CD-ROM. If you have two, set one to "Master" and the second
to "Slave." NOTE: If you are using more than one CD-ROM, it's best to
use the same IDE cable for both.
3. Attach audio cable. You can either do
this step now and string the cable
through the bay or wait until you have
the CD-ROM installed. Using the cable
shown below, simply connect it to the
back of the CD-ROM drive. I will show
where to plug in the other end in our PCI
section.

53. Installing the AGP Video
Card

54. 1. Remove unnecessary temporary metal plate. Only
remove the metal plate from the slot you are going to
use. If you do not remove this you cannot install your
video card.

56. Install PCI Components

58. 5. Give it CD sound. Remember that audio cable
from the CD-ROM drive? Now we will connect
the other end of it. If you want to hear audio
when playing a cd in your CD-ROM, you need to
connect the CD-ROM to the Sound Card (or
motherboard if your sound card is integrated in)
using the audio cable as seen below. Refer to
your sound card owner’s manual for correct
placement.
6. Repeat for any other components. Every
component is different but as long as it's PCI
compatible, it is installed the same way (except for
the audio cable. It is installed only on sound cards
and motherboards.)
