How To Build your Own Personal Computer

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!
