How to Build and Assemble a Computer

Building and assembling a computer, for those who have a penchant to do so, may be a very rewarding experience. If you are reading this article on”Building and assembling a computer”, you are probably contemplating on building or assembling a computer instead of purchasing one pre-built or pre-assembled Computer. Building or assembling a desktop PC is a viable option for many people and may bring significant benefits, such as:

  • To create your own assembled gaming computer or high end computer and saving money
  • To Learn about computer components, how they fit and work together
  • To Learn and understand computer hardware terminology and ’geek-speak’
  • Ability to customize a computer according to specialized specifications
  • Engendering technical problem solving ability

Before starting I would like to tell you that learning and troubleshooting with computer hardware is most interesting and at the same time difficult too. Before you decide to go and buy computer parts and build, here you need to understand the basic parts which are needed and understand its uses before you build a computer.

The first step in building a computer is acquiring the parts. We would explain every single part, which are needed and its used in the system, a quick explanation of essential parts:

Now every computer has CPU , MONITOR/LCD, Keyboard and Mouse, as seen in the below picture.

Build and Assemble a Computer

The main part of computer is CPU i.e Computer chassis or System Unit, which houses several internal components, and the external components, including peripherals. To build a High End or gaming system, you would need to build the CPU accordingly.

Inside the case the following internal parts are:

smps(SMPS)Power Supply/PSU: Power supply unit, converts outlet power, which is alternating current (AC), to direct current (DC), which is what the internal components require, as well as providing appropriate voltages and currents for the various internal components. While buying SMPS, you need to understand the overall requirement of the system power. In case you opt for Graphic card then you may require an SMPS with more power.

 

MotherboardMotherboard/mainboard: As the name indicates, this is the electronic centerpiece of the computer, everything else connects to the motherboard. It is very necessary to buy a motherboard based on CPU architecture. Always make sure that your motherboard support CPU or vice versa. Motherboard and CPU are the essential part of the system as performance is based on both the unit. Based on motherboard specification, you can proceed to buy RAM and CPU, which support your motherboard.

 

CPUProcessor/CPU: Central processing unit, the “brain” of the computer, most actual computation takes place here. CPU(Processor) sits on the motherboard. CPU is a bit expensive. Based on your budget, choose appropriate CPU, which meets your requirement. Make sure you buy a motherboard which supports your CPU. Market leaders in CPU are Intel and AMD.

 

 

RAMRAM: Random-access memory, the “short-term memory” of a computer, used by the CPU to store program instructions and data upon which it is currently operating. More capacities of RAM mean greater the speed of the computer. At present, there are different types of RAM available, i.e. DDR, DDR2 & DDR3. Based on your motherboard support, buy RAM accordingly. In case you buy a motherboard which supports DDR3 RAM, and you bought DDR2 then it won’t work.

 

Hard DriveHard Drive/Hard Disk: The “long-term memory” of the computer, used for persistent storage, i.e. the things stored on it remain even when the computer is powered down. The operating system, and all your programs and data are stored here.for e.g.: picture, songs. You can buy Hard-Drive space according to your need, i.e. 1 TB or 2TB, etc….

 

Optical DriveOptical Drive: Device for reading/writing optical disks. It may read CDs, DVDs, or other optical media, depending on the type. It is essential for installing operating systems or programs through CD or DVD. You may even write on the Disc using CD/DVD writers. Usually, DVD writers are used widely since, you can read as well as write on DVD Disc or CD Disc.

Graphics CardGraphics Card/GPU (Optional): If you’re concerned about good graphics for playing HD movies or playing games, or you are Graphic Designer, then this should be on top priority of your list. It basically deals with processing related to video output. For basic users who are not concerned with graphics, for them, there is no need to add graphic card. Some motherboards have an “onboard” GPU built-in, so you don’t need to add a separate video card. At present, Game’s requirements for graphics are higher, so higher is your Graphic memory requirement for 3D and HD games that can be played on your PC. Market leaders in GPU are Nvidia and AMD.

 

You will also need these external components:
• Keyboard for typing on. Many motherboards won’t even boot without a keyboard attached.
• Mouse for pointing and clicking. Unless you chose a text-based operating system, you will likely want one of these.
• Monitor, for display purpose. They come in many forms, the most common being CRT, LCD and lately has LED.

After having knowledge of all parts required to build and assemble a computer, You can shop according to your need. In next tutorial, we will see how these parts are assembled.
