If you are assembling a computer, you need to find a reliable source for the computer components. If the components you use are faulty, you will waste a lot of time troubleshooting the assembled computer. It could also damage the other components used for assembly the computer,  increasing the cost of  your assembled computer.

One option for getting the computer components is to contact the local computer hardware shop or dealer.  If the dealer can be trusted and you have purchased parts from them earlier, you could get a good deal.  The advantage is that you can physically examine the components before purchase and it is easy to return or exchange them in case of any problem.

For online purchases, check the reputation of the website before taking  a decision.  Newegg  (www.newegg.com) is a popular online store for computer parts.  They carry a wide range of computer components,  and detailed specifications of each component are listed, so that the buyer can verify that all the components are compatible and will work properly together. The prices of the computers are competitive compared to other online stores.  Each product listed at Newegg is rated by the customer on a rating scale of 1 to 5  for the convenience of the buyer.

Assembling a computer at home involves the following steps:

STEP 1:
Install your motherboard on the casing first. Put plastic stands-off under motherboard. Place in position in casing and install all screws required.

STEP 2:
Mount the CPU on the motherboard – being careful to position as required, as the fine pins are quite soft. This may take some time. Install the Cooler Fan Heat Sink assembly. Apply the paste which adds adhesion and contributes to the cooling effect on the top of CPU before clipping on the fan.

STEP 3:
Install the RAM module. To allow for easy insertion of RAM, push the white levers on both sides down. The gap in the RAM module should be matched to the slot. Push down the RAM firmly and pull the levers back up. They will click into position.

Any new motherboard should come with a diagram of the RAM layout. If there are empty slots a single ram module must be installed in the proper order.

STEP 4:
After the RAM is installed, the graphic card should be installed. It is usually next to the RAM slots and the may have to be pulled out if  the RAM was installed later .

STEP 5:
Install all the drives – the DVDRom, Floppy Disc Drive and HDD.

STEP 6:
Wiring up. Fit all your drives data cabling for the HDD, floppy disk drive (if needed) and DVDRom drive. These cables carry data signals between  hardware and the motherboard. They should be installed with their red edge facing the power supply plug.

For most motherboards, the primary slot is assigned to the HDD, the secondary slot will support an additional HDD/DVD Rom drive and the third slot will support the floppy drive.

STEP 7:
Connect up the mouse, keyboard and monitor.

LAST STEP:
As a last step, connect up all power plugs to the motherboard and drives. The main power source from the power box should be connected first.
