Before
Installation of the Motherboard:
I recommend that
you install the CPU and Heatsink/Fan before installation of the
Motherboard. It’s easier to do outside of the case.
Your new case
should come with brass mounting screws that screw directly into
the case and the spacers that keep the Motherboard at a distance from the
body of the case. Use the spacers! If you just screw the board
straight on to the case, you will blow the whole project.

The studs are
screwed into the chassis of the case.
Make sure you have
your anti-static protection in place, and then carefully place
the board into the case to determine where the studs should be
put.
Put a fine tip
felt pen through the holes in the board and mark the chassis
where the studs should go. This prevents you putting in a stud
that doesn’t match up with a hole on the board. Check the
positioning and screw the studs into the chassis. You can also
use the plastic spacers but I generally keep them for the edges
of the board if there are any spare holes on the board.

When the studs are
firmly in the chassis, you can screw the motherboard in to the
case via the studs.
But it is easier
to install the CPU and Heatsink/Fan on the Motherboard before you screw
it into the case, because you have more room outside of the
case.
Installing The CPU
Install the CPU
before any other component. Every Motherboard has a surface mount Zero
Force Insertion (ZIF) socket. With the Pentium, this is a 478 –
pin socket, shown at 7 in the Motherboard diagram in figure 1.1

The actual processor itself has a
gold mark indicating the orientation of the CPU in
the socket.

Follow the next steps in this section
carefully to install the CPU in the onboard socket.
You must also install the specific
CPU fan designed in tandem for that CPU after you
install the CPU. The next section describes the fan
installation.
1.Pull the socket
lever sideways, and then turn the lever up 90 degrees to raise
the upper part of the socket from the lower platform.

2. Configure pin 1 of the CPU to Pin
1 of the socket, as shown in the diagram below.
The CPU should
simply fall into the socket
DO NOT FORCE IT INTO
THE SOCKET.

3. Make sure that
all the CPU pins entered the socket completely and it is flat to
the surface. Then you can lower the lever to lock the CPU in the
socket.

4. With the CPU now locked in its
socket, you can mount the heatsink and fan.
Mounting the
Heatsink and Fan
The CPU needs a
cooling system, the heatsink/fan.


In the P4, the
heatsink and fan are an all-in-one unit that has 4 retention
clamps and 2 retention locks. The mounting for the heatsink/fan
unit is already on the Motherboard in the Pentium boards. You just have
to push the unit down on top of the CPU. Figure 2.11 shows the
fully-fitted unit.

Connect
the fan to the Motherboard. The manual that came with your Motherboard will show
the location. It's a three-pin connector. Just plug it in.

Installing the
Motherboard
Now the Motherboard and CPU Heatsink/Fan are in place, we can install the Motherboard.

Align the holes in
the Motherboard with the studs you put in the case and then screw the Motherboard
into the case!
Now we can start to add components to turn the board into your
PC!
