IT Workshop Manual Assembling of the Computer

Assembling of a CPU: Step I: The Motherboard: When installing the motherboard, make sure that you place it into the chassis in the correct orientation. The edge with external ports goes to the rear part of the chassis. Refer to the image below. Place six (6) screws into the holes indicated by circles to secure the motherboard to the chassis. Do not over tighten the screws! Doing so may damage the motherboard.

Place this side towards the rear of the chassis

Step II: The CPU (Central Processing Unit): The motherboard comes with a surface mount 478-pin Zero Insertion Force (ZIF) socket. To insert the CPU into the socket on the motherboard you will first have to raise the lever on the side of the socket. The socket will have a pin slot missing and the processor will have a pin missing and will have the corner colored or marked in some way to indicate that it is the corner you must align with the missing pin slot, once aligned properly the processor will fit in easily without any force needing to be applied, once the processor is in lower the lever on the side of the socket to lock the processor in place. If your processor has come with a thermal pad or thermal paste you will need to apply this to the top of the processor now this helps to transfer heat to the cooler, after you have done this you can place the cooler on top of the processor. Make sure the cooler is firmly attached. If it comes loose it can cause serious damage.

Installing of the CPU Follow these steps to install a CPU. 1. Locate the 478-pin ZIF socket on the motherboard.


2. Unlock the socket by pressing the lever sideways, and then lift it up to a 90°-100° angle.

Socket Lever

Make sure that the socket lever is lifted up to 90°-100° angle, otherwise the CPU does not fit in completely. 3. Position the CPU above the socket such that its marked corner matches the base of the socket lever. 4. Carefully insert the CPU into the socket until it fits in place. The CPU fits only in one correct orientation. DO NOT force the CPU into the socket to prevent bending the pins and damaging the CPU!


5. When the CPU is in place, press it firmly on the socket while you push down the socket lever to secure the CPU. The lever clicks on the side tab to indicate that it is locked. Gold Mark

Installing the Heat Sink: 1. Place the heat sink on top of the installed CPU, making sure that the heat sink fits properly on the retention module base.

Make sure that the fan and retention mechanism assembly perfectly fits the heat sink and module base; otherwise you cannot snap the hooks into the holes. Keep the retention locks lifted upward while fitting the retention mechanism to the module base. 3. Push down the locks on the retention mechanism to secure the heat sink and fan to the module base. When secure, the retention locks should point to opposite directions.



4. When the fan, heat sink, and the retention mechanism are in place, connect the CPU fan cable to the connector on the motherboard labeled CPUFAN1. Step III: The RAM (Random Access Memory) The RAM is easy to install. Different types of RAM will have the notch in different positions. Make sure you have the right type of RAM for your motherboard - check your motherboard manual to ensure this. Presuming you're using the right kind of RAM, the notch at the bottom will line up with the key in the memory slot. Now line it up and carefully press the memory into the slot - a little force may need to be applied to get it to seat correctly in the slot then once the clips close your know its securely seated. When dealing with older RAM it may be necessary to insert it on an angle to get it to fit in correctly. Follow these steps to install a RAM.

1. Unlock a DIMM socket by pressing the retaining clips outward. 2. Align a DIMM on the socket such that the notch on the DIMM matches the break on the socket.

Unlocked Retaining Clip 3. Firmly insert the DIMM into the socket until the retaining clips snap back in place and the DIMM is properly seated.

Step IV: AGP (Advanced Graphics Port)

All good modern video cards will need to be seated in the AGP slot, if you're dealing with an older video card it may need to be seated in the PCI slot which we will cover later, the AGP slot will be brown in colour. You will need to remove the metal tab at the back of the case, if it’s a new case you can just break these off, afterwards though you will need to screw in or use a plastic clip to hold the metal tab in place. Only do this if you have broken off a tab and do not intend to place a PCI card there. Installing the graphics card is easy - simply insert it into the slot and make sure it is seated correctly then use a screw to hold it in place.

StepV:PCI(PeripheralComponentInterconnect) There are six 32-bit PCI slots in this motherboard. The slots support PCI cards such as a LAN card, SCSI card, USB card, and other cards that comply with PCI specifications. The following figure shows a LAN card installed on a PCI slot. There will be several free slots for various PCI cards, try to space them out if possible to prevent heat buildup in the system. Once you have installed a PCI card it is best not to remove it then place it in another slot as this can cause IRQ conflicts with some motherboards.The PCI slot 6 shares with the ACR slot. If you installed a card into the ACR slot, you may not use the PCI6 slot.

Step VI: Floppy Disk To install the disk drive simply slide it into the drive bay remembering to remove the plastic front panels first and removing any metal panels behind this by knocking them out. It will be the smaller of the drive bays and will be located nearer the bottom compared to the larger CD-ROM drive bays which will be located nearer the top. Once you have slid the Floppy disk drive in, secure it with screws.

Step VII: HDD (Hard Disk Drive) The HDD goes in a similar way as floppy disk but will be hidden behind the casing and is fixed into position in the exact same way as the floppy disk drive, except will only require 2 screws instead of four. Just remember to set the drive as you want it either master single or slave. This is done by changing the jumper settings at the back of the drive.



Step VIII: CD-ROM (Compact Disk-Read Only Memory) Putting in the CD-ROM drive or CD-Writer is the same as putting in the HDD - just remember to use the fine threaded screws, also remember to first set the jumper settings to either slave or master bearing in mind you cannot have 2 masters.

Step IX: Ribbon Cables Ok so now everything you want is installed and you’re getting close to finishing up but first you will need to connect all the cables. IDE connectors (PRIMARY IDE/SECONDARY IDE): An IDE (integrated drive electronics) cable connects a hard drive or CD drive to the main board of the computer. 1. Pin 20 on each IDE connector is removed to match the covered hole on the UltraDMA cable connector. This prevents incorrect orientation when you connect the cables. 2. The hole near the blue connector on the UltraDMA/100/66 cable is intentional.



Floppy disk drive connector (34-1 pin FLOPPY): This connector supports the provided floppy drive ribbon cable. After connecting one end to the motherboard, connect the other end to the floppy drive.



Step X: Drive Power Connectors

Drive power connection is the large 4 pin connections they can only fit in one way so don’t worry about plugging them in the wrong way around, a bit of force to ensure there fitting snugly may be needed. Just remember the floppy drive will use a smaller plug. The last plug is the larger ATX plug that plugs into the power socket on the motherboard.

Step XI: Close the cabin by fixing the screws.
