This tutorial is aimed at helping you to build your own computer. There are many different combinations of hardware you can have. we will deal with the basics to enable you to get a computer up and running.
Philips Crosshead Screwdriver, Overhead light source, Tweezers, Wrist strap to attach you to case
PC Case, Floppy Disk Drive, CD Rom Drive, Hard Drive, Motherboard, Processor, Processor Heat Sink(fan), RAM, Power Supply, Video Card, Keyboard and Mouse

Operating System, Drivers (come with hardware), motherboard CD
Cables and Extras
Drive Cables, Screws (usually with PC Case), CPU Cooling Compound, Power Cords for computer and monitor
Step 1…Install Power Supply Unit (PSU), CPU and Heat Sink on the motherboard
Remove the case cover by unscrewing the four to six screws and taking the cover off. Lay the case on it side with the metal back plate facing up to you. Some cases come with a preinstalled PSU others do not. To install a PSU slide the PSU into place with the wires facing forward into the case and the fan blowing out the back. Secure it in place with some screws so that it does not move. Set the voltage to 220 in the UK, 120 USA. The back plate may need changing to match your motherboard. To do this break off the old plate and take the new plate (packed with motherboard) and install it in place of the old one.
The motherboard should be sat on a secure surface in/on the antistatic bag it came in. To install the CPU make sure the lever on the motherboard is up (refer to the manual supplied with you motherboard to see how this is done) take the processor out of the box it came in by only touching the edges of the chip. Place this into the socket by matching pin 1 to the correct place on motherboard. Usually a gold arrow lines up with another mark on the socket. Once in place Push the lever arm down to lock the processor in place.
To install the Heat Sink/fan onto the processor, clean the processor with a lint free cloth to remove dust and finger oil. Take the cooling compound and squirt a small amount onto the processor directly taking care not to use too much as it may go over the edges. Spread this evenly over the surface of the processor. Take the Heat Sink and place it directly on top of the processor pushing down slightly to ensure good connection between the processor/compound and Heat Sink. Using the clips on either side of the Heat Sink secure this in place on top of the processor. Check that no cooling compound has leaked from the sides otherwise you have to start again and clean both the Processor and Heat Sink. Once the Heat Sink is in place plug in the power cord attached to it into the motherboard see manual suplpied with your motherboard to determine which one. This is step 1 complete.
Step 2…Install memory modules (RAM) and Motherboard into the case
To install the memory modules Attach the antistatic wrist strap to an unpainted metal surface to earth yourself and discharge and static built up. On the motherboard you should see the slot for the memory module. Make sure the clips at either end are open i.e. tilted backwards. Pick up the memory module by the edges and place it into the slot by lining up the notches and making sure the both ends are in the clips. Push down firmly and the clips should pop shut. This is the memory Installed.
The motherboard should now have the processor, Heat Sink and memory installed. The motherboard can now be placed into the case. To install the motherboard into the case look at the holes on the motherboard and the holes on the motherboard plate in the case. Take the motherboard standoff screws and screw them into the motherboard plate in line with the holes on the motherboard. Once this is done take the motherboard and place it into the case with the inputs and outputs facing toward the back of the case. These should fit into the back plate of the case. Take some screws and screw the motherboard into the stand offs. Do not screw too tightly otherwise the circuits on the motherboard may break but enough so there is no movement. Step 2 is complete.
Step 3…Connect the Motherboard to the Case Wires and PSU
Now the motherboard is in place take the 20 or 24 Pin connector from the power supply and connect it to the motherboard. The board may also require a 4 Pin connector to power the CPU. Plug this in too. The case should also have a set of wires which will plug into the motherboard. refer to the manual supplied with your motherboard to install these correctly. Usually the connector labelled PWR_SW is the power switch and RST is the RESET button. The Power LED and Hard Drive LED must also be attached. Once all the connectors are connected move to Step 4.
Step 4…Install the Floppy Drive, Hard Drive, and CD-ROM Drive
To install the floppy drive choose which drive bay you want the floppy drive in and remove the face plate on the case. Slide the drive in from the front and make sure it lines up with the face plate as well as the screw holes on the mounting rack. Screw the drive into place. Connect the power supply to the floppy drive this is the smallest connector coming out of the PSU. Take the ribbon cable and attach it to the back of the floppy drive, this cable has a twist in it. Attach this to the motherboard lining up the red edge. If you do not line this up the drive simply wont work. When attached to the port on the motherboard the floppy drive is installed.
To install the Hard Drive determine which bay you are going to put it in. Slide it in from the back and match up the screw holes to the mounting plate. When this is done secure it in place. Attach the 4 pin Molex connector from the PSU to the back of the drive, it will only fit one way. If the drive is IDE it will have a big connector on the back, if this is the case take the ribbon cable and attach this to IDE 1 on the motherboard. If the drive is SATA the connector will be much smaller and the cable a lot thinner. If this is the case take the cable and attach it to the back of the drive then to SATA_1 on the motherboard. This is the hard drive installed.
To install the CD ROM drive this is very similar to the floppy drive. Choose which bay you want it in and take the face plate off. Slide the drive in from the front and screw it into place. Attach the 4 pin Molex connector as you did with the hard drive and then take the ribbon cable and attach this to IDE_2 on the motherboard. This is Step 4 complete.
Step 5… Install the Video Card
A video card is required so that you can see the output from your PC there are two types used older AGP cards or newer PCI Express Cards. To install a Video Card you should see a brown slot known as an AGP slot if you card is AGP then it goes here. Open the slot at the back of the AGP slot there may be a clip like with the memory modules, this is to support the card as they are now quite big. Break off the metal covering the hole at the back of the case. Take the video card by holding the edges only and slot it into this port and press down firmly, you should feel it click into place. Do not over force it as this may damage the circuits and your motherboard. Once in place secure the card by screwing it to the back of the Case you should see this on the metal plate at the back. Some Video Cards require additional power now so attach the 4 pin Molex connector to the video card. This is the Video Card Installed.
For PCI Express follow above but use the PCI Express slot instead.
Step 6…Initial boot up and configuring the bios
Well done you have now completed building you computer. It is now time to see if the thing works!!!
Plug in the computer and attach the mouse and keyboard. Before you hit the power button here is what to look for: The PSU and Processor fans Start spinning, The power LED comes on, The Hard Drive boots up. You may hear a bleep from the PC speaker. If you hear multiple beeps this means there is an error somewhere. If there are strange grinding sounds then turn off the computer immediately.
Turn on the computer, if you see the bios screen hit the appropriate key to enter the bios and check if everything is working properly. If this is the case then set the boot device to CD. Congratulations you have now completed building you computer.
