How to build a PC?

Building a computer may seem daunting, but with a little knowledge and patience, it can be a fun and rewarding experience. I believe in building your own computer because, in that way, a person can learn how sensitive yet easy it is to do so. In this article, we will cover the basic steps required to build a computer from scratch.

Choose Your PC Components

The first step in building a computer is choosing the components. Here is a list of the essential parts you will need:

  • CPU (Central Processing Unit)
  • Motherboard
  • RAM (Random Access Memory)
  • Storage (SSD/HDD)
  • Power Supply
  • Case
  • Optional: Graphics Card, Sound Card, Optical Drive, Wi-Fi Card, etc.

When choosing your components, it is important to ensure that they are all compatible with each other. This means that the motherboard needs to be compatible with the CPU, RAM, and other components. The power supply needs to be powerful enough to support all the components in the system

Additionally, you will want to consider your budget and the type of computer you want to build. Are you building a gaming PC or a workstation? Do you need a high-end graphics card, or will the onboard graphics be sufficient? You will need to answer these questions before choosing your components. For e.g., my computer is more of a creator-specific computer because I do a lot of video editing and other related stuff.

Internals of  PC

Let me give you a little bit of information about the necessary components needed to build a pc:

What is a CPU?

CPU stands for Central Processing Unit. It is the primary component of a computer that is responsible for carrying out the instructions of a computer program. The CPU is often referred to as the “brain” of the computer because it performs most of the calculations and logical operations that allow the computer to function.

Different types of CPUs have different architectures, clock speeds, and other features that can affect their performance. CPUs are used in various devices, from desktop and laptop computers to smartphones and game consoles.

The CPU I recommend you get will be a minimum of core i5, which you can get on amazon by clicking here.

What is a Motherboard?

A motherboard, or a mainboard or system board, is a computer’s primary printed circuit board (PCB). It is responsible for connecting and controlling a computer’s hardware components, such as the CPU, RAM, hard drive, and graphics card. The motherboard also contains various input/output ports, such as USB and audio ports, and expansion slots for adding additional hardware components. In essence, the motherboard is the central nervous system of a computer, allowing all the components to communicate and work together seamlessly.

My recommended motherboard will be ASUS, as I have been using that for the past couple of years, and it has never failed me once. Buy it from amazon by clicking here.

What is a RAM?

RAM (Random Access Memory) is a type of computer memory that is used to temporarily store data that the computer is currently using or processing. RAM is a volatile memory, which means that it loses its contents when the power is turned off.

When a computer runs a program, it loads the program’s data and instructions into RAM so that the CPU (Central Processing Unit) can quickly access and use them. The more RAM a computer has, the more data and instructions it can hold in memory, which allows it to run more programs simultaneously and switch between them more quickly.

RAM is measured in bytes, and the amount of RAM a computer has is an important factor in determining its overall performance. More RAM can help improve a computer’s speed and multitasking capabilities, but it is not the only factor that affects performance. Other factors, such as the CPU and storage drive, also play a role in determining a computer’s overall speed and responsiveness.

I recommend getting at least 8 GB of ram for regular work and 16 GB of ram for extended work. But the best way of future-proofing your computer is to buy this package from amazon, where you are getting two rams (16 GB each) at an amazing offer. Check It out!

What does a Storage in a PC do?

Storage in a PC refers to the component that stores digital data for the computer to access and use. It is where all the files, programs, and operating systems are stored.

There are two main types of storage in a PC:

Hard Disk Drive (HDD): This is a traditional storage device that uses spinning disks to read and write data. It stores data on magnetic platters and uses a read/write head to access and writes data. If you ask me, I personally would want you to get the latter one.

Solid State Drive (SSD): This newer storage device does not use spinning disks. Instead, it uses flash memory chips to store data. SSDs are faster than HDDs and are becoming increasingly popular in modern PCs. SSD is the way to go for me!

The storage in a PC is essential because it allows users to save files, documents, pictures, videos, and other types of data. Without storage, users could not save their work or access files from previous sessions. The storage also allows the computer to boot up and load the operating system and other necessary programs.

I have been using only SSD for the past few years and am truly in love with it! So I would definitely advise you to get an SSD. Check out my recommended SSD from amazon by clicking here.

What is the purpose of a Power supply in a pc?

The purpose of a power supply in a PC is to convert the alternating current (AC) power from the wall outlet into direct current (DC) power that the computer’s internal components can use.

The power supply unit (PSU) takes the AC power and converts it into several different DC voltages, such as 3.3V, 5V, and 12V, which are required by the motherboard, CPU, graphics card, and other components. The power supply also regulates the voltage to ensure that the components receive a consistent and stable supply of power, which is important for the proper functioning and longevity of the computer.

The power supply is an essential PC component because it provides the energy needed to power all the internal components. Without a power supply, a computer would not be able to operate. Choosing a high-quality power supply is important to ensure the computer receives a reliable and stable power supply, which can help prevent hardware damage and system crashes.

What is the purpose of case in a PC?

The case of a PC, also known as a computer chassis, is the outer shell that houses all the internal components of a computer. The case is usually made of metal or plastic and provides protection, organization, and cooling for the internal components.

The case typically consists of several parts, including:

The frame: This is the backbone of the case and provides structural support for all the internal components.

The side panels are removable panels that allow access to the inside of the case for maintenance, upgrades, and installation of components.

The front panel: This is part of the case that faces the user and contains the power button, USB ports, audio jacks, and other inputs and outputs.

The drive bays: These are slots for installing hard disk drives (HDDs), solid-state drives (SSDs), optical drives, and other storage devices.

The cooling system: The case contains fans and ventilation to dissipate heat generated by the internal components.

The case of a PC is essential for several reasons. It protects the internal components from physical damage and helps to organize them for efficient cooling and airflow. It also gives the user easy access to the internal components for maintenance and upgrades. Additionally, the case can have aesthetic and design elements that make it appealing and customizable to the user’s preferences.

How to assemble the components of a computer?

Once you have your components, the next step is to assemble them. This can be a bit intimidating if you have never built a computer before, but don’t worry. It’s actually quite simple. Let me explain to you how:

(Note: Building a computer is tough and can be dangerous. If you have never even seen how to assemble a PC, I recommend asking for a professional’s help.)

Installing CPU

The first thing you should do is install the CPU onto the motherboard. Different CPUs have different installation methods, so be sure to consult the manual that comes with your CPU. After installing the CPU, you will need to install the RAM. The RAM slots are usually near the CPU socket, but consult the motherboard manual to confirm.

Storage Installation

Next, you will need to install the storage. Most motherboards have multiple SATA ports, which you can use to connect your storage drives. Be sure to connect the power cable from the power supply to the storage drive as well.

Power Supply

After that, you will need to install the power supply. This is typically done by screwing it into the case using the provided screws. Once the power supply is installed, you must connect all the power cables to the appropriate components, including the motherboard, CPU, storage drives, and other components requiring power.

Graphics card and other important stuff

Finally, you will need to install the case fans and any other optional components, such as a graphics card, sound card, or Wi-Fi card.

How to Install an Operating System in a PC?

Once you have assembled your computer, installing an operating system is next. This software runs on your computer and allows you to use it. There are many different operating systems to choose from, but the most popular are Windows, macOS, and Linux. I personally use windows on my computers.

To install an operating system, you will need to create a bootable USB drive or DVD. You can download the operating system from the official website and use a tool like Rufus to create a bootable USB drive. Once you have the bootable USB drive, you will need to change the boot order in the BIOS to boot from the USB drive. This will start the installation process.

The installation process varies depending on the operating system you are installing but typically involves selecting a language, agreeing to the license agreement, and choosing the installation location. Once the installation is complete, you must install any necessary drivers for your components.

Install Drivers and Software

After you have installed the operating system, you will need to install drivers for your components. This includes drivers for the motherboard, CPU, graphics card, and other components requiring drivers. You can download these drivers from the manufacturer’s website.

Once you have installed the drivers, you can install any software you need. This includes web browsers, office suites, media players, and any other software you need for your specific use case.

Testing Your Computer

Before you start using your computer, it’s crucial to test it to ensure everything is working properly. This includes running a stress test to ensure that the CPU and graphics card are functioning correctly and that the temperatures are within safe limits. You can use a tool like Prime95 or FurMark to stress test your components.

Additionally, you can run benchmark tests to see how your computer compares to others. This can show you how well your computer will perform in different tasks, such as gaming or video editing.

Customize Your Setup

Once you have confirmed that your computer is working properly, you can start customizing your setup. This includes adjusting the BIOS settings to optimize performance, installing additional software, and customizing the desktop environment.

You can also add peripherals such as a keyboard, mouse, and monitor to complete your setup. If you are building a gaming PC, you may want to invest in a gaming keyboard, mouse, and a high-refresh-rate monitor.
