Custom build pc

Computer has very complex components. Some of us maybe don't know the parts and functions of it. Sometimes when we are using our computers, we sometimes notice some errors or we feel that its performance has slowed down. So we wonder what's happening. Even though we free up some space or defragment it still nothing has change. So point of buying or upgrading will come.

In my opinion, I'd rather upgrade my computer than buying new one to save money. And then decide whether you will do it yourself or ask a technician to do it for you. But if you have decided to do it yourself then here are some tips that I can give you in building/upgrading your pc.

First you must do a lot of reading and reasearch all about computer and identify all the components that makes the computer work.

Here are the primary components of the pc

  • CPU or the Processor
  • Motherboard
  • Memory (RAM)
  • Hard Disk Drive
  • Video Card/ Graphics Card
  • Computer Case
  • Power Supply
  • CdRom/ DVDRom

So what are are the funtions of these components?


CPU or the Processor

The Central Processing Unit (CPU) or the processor is the portion of a computer system that carries out the instructions of a computer program, and is the primary element carrying out the computer's functions.  Choosing the right CPU depends on what's your systems usage pattern.  You decide whether you use it for video editing, gaming, word processing or simply just a family web browsing. 



A motherboard is the central printed circuit board (PCB) in many modern computers and holds many of the crucial components of the system, while providing connectors for other peripherals. The motherboard is sometimes alternatively known as the main board, system board.  It is also sometimes casually shortened to mobo.

Memory (RAM)

Random Access Memory (RAM) is simply called "Memory". It's memory that is directly readable by the Central Processing Unit (CPU) of a computer system. Every computer system has a RAM. It's installed into the motherboard slots of a computer. For a better and fast execution of programs a computer system should have large RAM.


Hard Disk Drive

A hard disk is a device that is used to store large amounts of data in a computer system. Hard disks differ from other memory because they are non-volatile, they retain the data even when they do not have power.

Video Card/ Graphics Card

A video card is a computer chip you usually insert into your computer via a AGP or PCIe slot inside of your computer. The purpose of the video card is to process images. The card processes the video instead of the computer, so you have better performance and better graphics on pretty much anything.

Video Card/ Graphics Card

Computer Case

The case has the primary function of housing, ventilating.

Computer Case

Power Supply

Power Supply

A power supply unit (PSU) is the component that supplies power to the other components in a computer. More specifically, a power supply unit is typically designed to convert general-purpose alternating current (AC) electric power from the mains to usable low-voltage DC power for the internal components of the computer.

Cd-rom/ DVD-rom

They are disc drives which read Compact Discs (CDs). They are versatile and transportable and can be used to perform various tasks such as reading data from the computer and listening to audio or installing drivers and OS


Sometimes we think that doing it ourselves is somehow difficult.  Through it we can learn and  we can know more informations about the pc that we are using.
