First Boot and BIOS Setup

Now that we have finished building the PC lets connect the base unit to a mains outlet. Connect a keyboard, mouse and monitor so that we are ready for the first boot. Turn the PC on by pressing the power switch. If everything goes well you will hear a short beep followed by a boot screen. At this stage we need to enter the BIOS to check that all the hardware is detected correctly. We will also make few changes so that we are ready to install an operating system such as Windows 7.

To enter bios setup press the delete key as the computer boots up. Please note it could be a different key on your system such as F1, so check your boot screen or manual for more details. This is the main bios setup menu.

Lets select the Intelligent Tweeker menu by pressing enter. As you can see the CPU speed, memory speed and size are detected correctly. Press escape to go back to the previous menu.

Lets enter Standard CMOS features. As you can see the hard drive and dvd writer are also detected correctly.

This time we will enter the Advanced BIOS features.

We will make our first boot device CDROM, and second boot device as hard disk.

By doing this we can make sure that the computer boot from Windows 7 DVD that is placed in the DVD drive. If the hard drive is set to first boot device it will not boot as it has no operating system installed.

Finally we can save & exit setup. At this stage you can place a operating system disc in the DVD drive and you are ready to install your chosen operating system.

This concludes our PC building guide. We hope you enjoyed these videos and managed to build your own perfect PC.

Final Check & Closing the case

Before you close the case double check everything to make sure you have not missed anything like attaching a cable. Make sure you have no screws lying around as it can short the motherboard. Slide the side panel back on to the case and close the screws.  If you are feeling confident you can leave the case open and power up the PC just to see if it boots and all the fans are spinning. You can also test your power button and reset button to make sure they work before closing the case. You have now completed building a PC from scratch.

Lets have a look at the front of the case.

Finally we will take a look at the back of the case.

Attach the power cable along with monitor, keyboard, mouse and other peripherals so that we are ready to boot.

How to Attach ATX Power Connector & Header Cables

To power up your motherboard you need to attach the power cables from the power supply unit. Your case has many header cables which also needs to be connected to the motherboard so the switches, led, usb sockets on front panel of the case functions properly.

Label 1 below shows the location of the ATX 2.0 power connector. It has 24 pins. It powers the motherboard and all the components. It has a fool proof design and only fits one way. Place the connector on top of the power socket making sure you are holding it the right way. Push the connector into the socket until it locks into position.

Label 2 shows the location of  ATX 12 Volts connector. It has 4 pins. It powers the processor. The connector only fits one way. Push the connector into the socket until it locks into place.

Label 3 shows the location for the header connectors. Your case has header cables for front USB, firewire, power switch, power LED, reset switch, speaker, etc. Connect each header cable to the labeled header as shown below. While attaching these little cables make sure the positive and negative pins are correct. Read your motherboard manual for more details.

How to install a graphics card | ASUS GeForce GT 430 1GB PCI-E

Many modern motherboards have integrated graphics. They are suitable for every day tasks such as browsing the web, email, word processing etc. For many people the integrated graphics is more than enough for their needs. However, if you are into 3D Games, CAD, or other application that requires GPU acceleration then you will need a dedicated graphics card. Nearly all graphics card made nowadays are PCI-E based and have either Nvidia or ATI (AMD) chipset.

This is an nvidia GT430 graphics card. This model is made by Asus and has VGA, DVI and HDMI connectors. Remove the metal plate covering the PCI Express slot. If you have more than one PCI Express slot make sure you choose the PCI Express x16 slot.

Align the card with the slot and press down on the card until it is fully seated in the slot. Make sure the metal contacts on the card are completely inserted into the slot. There is a latch at the end of the slot which locks the card into place. Finally screw the card down using a screw driver so its securely seated.

How to install a SATA DVD Writer | Pioneer S18 DVD -RW Drive

To install a software or an operating system you need some kind of DVD drive. Using a DVD writer you can have best of both world as it allows reading and writing to DVD media. DVD writers are very useful for backing up your data. It is also very economical due to the cost of DVD media. Installing a DVD writer is a very simple process. If you have a retail drive it will come with mounting screws. The first thing you need to do is locate an empty drive bay. Take out the plastic or metal cover that is blocking the access to the bay. Depending on your ATX case, you can either push the cover from inside the case to release it or you need to pull off the front panel as I have done on this ATX case.

Once the plastic cover is out you can slide the DVD writer into the drive bay. Make sure the drive aligns perfectly with the case as shown below:

Lock the drive into place using the lock slider or if your case does not have locking mechanism you can just screw it into place. Attach the Sata power cable by gently pushing it into the socket. It will only fit one way  so check the orientation before pushing it into place. Attach the Sata data cable to the DVD writer. It only fits one way. The connectors are like an L shape, so check the orientation to match the DVD writer before pushing it into place.

Finally attach the other end of the data cable to an empty SATA socket on the motherboard.

How to install a SATA Hard Drive | Seagate Barracuda 500GB 7200.12

Installing a SATA hard drive is a very simple and straight forward task. Unlike IDE hard drives there are no jumpers to set and each drive connects to the motherboard using an individual SATA cable. There are other advantages to using a SATA hard drive such as much faster data transfer and better performance. If your motherboard has a E-SATA port then you can even use a SATA hard drive externally.

The first thing to do is choose an empty 3.5 inch hard drive bay. Position the drive so its ready to be inserted into the bay. Gently slide the hard drive into the bay as shown. Make sure the circuit side of the hard drive is facing down towards the bottom of the case. Finally lock the hard drive into place using the lock slider or if your case does not have a lock mechanism you can just screw it into place.

The image below is a SATA power cable. Attach the SATA power cable by gently pushing it into place.

It will only fit one way so check the orientation before pushing it into place.

The image below is SATA data cable. Attach the SATA data cable to the hard drive. It only fits one way.

The connectors are like an L shape so check the orientation to match the hard drive before pushing it into place.

Finally attach the other end of the SATA cable to the motherboard.

How to install DDR3 SDRAM Memory | Crucial PC3 10600

To build a stable system it is always a good idea to buy high quality memory modules. Over the years I have always used memory from Crucial as you can buy it direct from Crucial website and it comes with life time warranty. The quality of Crucial memory is extremely high and I never had a single problem with them during the 10 years i have been using them. This is the reason I have chosen to use Crucial DDR3 SDRAM on this system. Please note DDR3 may look similar to DDR2 but the pin count are not the same and they are not compatible. So you are out of luck if you want to recycle your old DDR2 memory.

Move both clips on the memory socket to open position. Since we have two DDR3 modules we will insert the first module into socket DIM1 and the second into DIM3. This will run the memory in Dual Channel Mode.  DIM1 and DIM3 sockets are colored blue. Please note, if you have 1 module it will be inserted into socket DIM1 and therefore will run in Single Channel mode.

You will notice that the DDR3 memory has a notch at the bottom. This is to prevent the memory from being inserted the wrong way round. Make the orientation of the memory module so that the notch matches the memory socket. Push the memory module down using two fingers or both of your thumbs as shown. You will hear a click as both clips on the memory socket snaps into place.

Repeat the same process for the second module.

How to install a Processor | Intel i3 540 Socket 1156

The socket on the motherboard below is known as Intel LGA 1156 CPU socket. This socket is designed for Intel i3, i5 and i7 processors. To open the socket gently push the lever handle down and away from the socket and lift upward. This will release the plastic protector. Lift the plastic protector and remove it from the socket. Unlike older generation Intel Motherboard sockets the LGA1156 does not have any holes. Instead the socket has 1156 pins sticking out. These are the pins that make contact with the processor. Please note the 1156 socket is not compatible with 1155 socket used for the new generation Intel Sandy Bridge based processors.

We are using Intel i3 540 processor which are the first generation i3 CPU’s. Take out the processor and the heat sink from box and leave it on the side.

When fitting a processor into the socket be careful to fit it correctly. To make sure this i3 540 processor only fits one way there are two notches on each side of the processor. There is also little gold triangle in one corner to indicate that its pin 1. Make sure pin 1 on the processor is aligned to pin 1 on the socket and the notches align perfectly. If everything is done correctly the processor will easily fall in to place.

Close the CPU lever so it covers the processor.  Finally close the lever handle by pushing down then towards the socket until it locks into position.

The next thing to do is to fit the CPU cooler. If you have a retail boxed processor it will come with an Intel CPU cooler like the one below. It has thermal paste applied on the heat sink so there is no need to add extra. The cooler has four push pins that fit perfectly into the holes in the motherboard. Place the cooler on top of the holes. Push firmly on top of each push pins. You will hear a click on each one to confirm its locked into position.

Take the CPU cooler power connector and attach it to the 4 pin fan socket. This is a very important step as it powers the fan on top of the heat sink which keeps the CPU cool.

How to install a Motherboard | Gigabyte GA-H55M-UD2H

Before installing any components you must discharge yourself from any static energy. This can be done by using an anti static wrist band. Or alternatively by touching a metal surface such as the metallic area of the case.

Before we start mounting the motherboard we need to fit the ATX back plate. These back plates come supplied with the motherboard. Back plates are normally labeled and colour coded. Make sure you are holding the back plate the right way up, and face the labeled side towards the back of the case. Using your fingers push the plate so that it snaps into position. It can take some force to get all the corners into place. Once the back plate sits correctly into place, it should look something like the image below. As you can see, the plate has cut out so the motherboard’s ports fit perfectly in to position.

The gold colored screws below are called standoff screws which are used for mounting the motherboard. Your case may have many holes for the standoff screws. Which holes should you use ? The easiest way to find out which holes to use is to place your motherboard on top of the holes. See which holes on the motherboard line up with the holes on the case. Mark the holes using a pencil. Those are the ones you’ll install the standoffs into.

Do not use extra standoff that does not match the motherboard as it will cause a short circuit. Start placing the standoff’s using your finger and tighten them using a plier.

This is a Gigabyte H55M UD2H motherboard. It has an Intel 1156 socket supporting i3, i5, and i7 processors. Place the motherboard on top of the standoff screws making sure that the ports slide into the back plate first. Use the supplied  screws that goes into the standoff’s to secure the motherboard. Place the screws into each hole and tighten it using a screw driver.

How to install ATX Power Supply | OCZ Xstream 400

I am using an OCZ 400 watts ATX power supply unit. Its enough to power up all the components that we are using. When choosing a PC power supply unit its a good idea to get one that provides slightly more watts than you need. This gives you the flexibility to add more hardware in the future. Before we can install a power supply unit we need to prepare our case. Start off by taking the screws off the case. The cooler master centurium case has 2 screws holding the side panel. Take the screws off and slide open the side panel. If you look at the back of the case you will notice that there is a cut out. This cut out is made for ATX power supply units and therefore any brand of power supply will fit perfectly into place.

Put your case in horizontal position so its easier to work with. Take your power supply and slide it towards the back of the case so that the screw holes on power supply unit align with the holes on the case.

The PSU should fit nicely into place as shown on the image below.

Start putting the screws in using your fingers and then tighten it using a Phillips screw driver as shown. The screws should be supplied with your power supply unit, if not you can use the screws supplied with the case.
