Why Does A Computer Need A Motherboard

The core piece of circuitry that all other connected components plug into to form a functional whole or the main printed circuit board in a computer. Why does a computer need a motherboard? The modern motherboards serve as the backbone of the computer, connecting all of its parts and enabling communication between them. 

None of the external components of the computer, optical drives, including the hard disc, GPU, and actual CPU, could interact without it. For a computer system to function properly, total motherboard functionality is key.

Computers are essential for most people in modern life, but not everyone knows why they need a motherboard.

The motherboard is the heart of the computer. It contains all the essential components like the CPU, memory, hard drive, and even graphics card. Without it, you won’t be able to use your computer.

If you don’t have a motherboard on your computer, then you are missing out on a lot of things. For example, you can’t use your computer as a printer, monitor, or CD/DVD drive. Plus, if you want to upgrade your motherboard, you will have to take it apart and replace it.

Your computer’s motherboard acts as its structural support system and distributes power. Consequently, many people are looking for How to install a motherboard.

What is a motherboard?

Why Does A Computer Need A Motherboard

In computer science, the term motherboard is also known as a mainboard, planar board or logic board, operating system board, mobo or MB. There are various input and output devices that make up the modern motherboard. 

A motherboard in a computer system is a printed circuit board (PCB) that offers various power connectors for all the components including the graphics processing unit (GPU), storage, system’s main memory, central processing unit (CPU) and other components acts as a form of backbone for various components’ communication. 

The modern motherboards that hold everything together in the majority of modern computers, including smartphones, tablets, notebooks, and desktop computers, are the only ones you’ll normally buy for yourself.

The second generation of computer memory bus connections, known as Serial Advanced Technology Attachment, is used to link motherboard host adapters to high-capacity storage devices. We have a block diagram of the motherboard.

To connect various components, the motherboard contains a variety of peripheral component interconnect express ports inside the computer chassis. The motherboard, which is the largest circuit board in tower computers, is located on either the left or right side of the tower.

What Does a Motherboard Do?

As far as the purpose of a motherboard is concerned, It is the circuit board that determines the kinds of storage devices, memory modules, video or graphics card (among other expansion cards) that can connect to your PC. Not all graphics card are compatible with any motherboard.

Whereas an operating system is just the initial main software that is run on the computer and provides many basic operations for other programs to use

A motherboard’s primary function is to distribute electricity from your power supply and links all of your hardware to your processor socket. 

Types of Motherboard:

Due to the requirement for computers to be integrated into machinery, moving vehicles, and other earthly equipment, the form factor of the computer plays a significant role. In the coming days, the motherboard’s nature and size will continue to evolve.

Below are the six different types of Motherboard:

  1. AT Motherboard
  2. ATX Motherboard
  3. LPX Motherboard
  4. BTX Motherboard
  5. Pico BTX motherboard
  6. Mini ITX motherboard

Following are the popular manufacturers of the motherboard.

  • Intel
  • ASUS
  • AOpen
  • ABIT
  • Biostar
  • Gigabyte
  • MSI

Why is a Motherboard Important?

A decent and proper motherboard consists of and holds the CPU socket, audio capacitors, PCIe slots, RAM, and other computer components in the precise position because it is the main circuit that connects all of the computer system’s components and peripherals.

Any PC’s motherboard plays a crucial part in the operating system. But let’s go through what a motherboard performs one more:

  • Motherboard Connects all the Other Computer Components
  • Handles Synchronization of Various Tasks
  • Contain the BIOS Chip
  • Contains the CMOS Battery and Chip forms
  • Handles Hardware Expansion
  • Controls Power Supply to Crucial Components

Components of a motherboard:

When it comes to the motherboard structure, the following motherboard components are located on it:

  • Central Processing Unit (CPU): All fundamental mathematical, logical, control, and basic input output system are carried out.
  • Chipset: it controls the data flow between the processor, memory, and any attached external devices.
  • Buses: a pathway that transfers data between motherboard components within a computer.
  • Random Access Memory (RAM): a temporary form of computer data storage that allows fast access to data. Since RAM is erratic, power is needed to maintain data accessibility.
  • Expansion slots: enable the addition of hard drives components above and beyond what was initially installed.
  • Ports: provides an interface between the computer and a peripheral device such as a mouse, keyboard, or printer

Cooling System Of A Motherboard:

Cooling System Of A Motherboard

Our PCs’ cooling is crucial, whether that means selecting the right heat sink for the CPU that fetches startup instructions and various wing connectors or the right radiator pumping motors for liquid cooling. It is important to differentiate between the motherboard’s fan connectors in any enclosure. It is of much importance to know How to connect extra fans to Motherboard?

How am I supposed to know if my motherboard is dead?

Like everything else in technology, motherboards ultimately fail or stop working. There are a variety of motherboard failure symptoms, some of which include:

  • failing or taking a long time to start up peripherals
  • Computer abruptly shuts down
  • Computer not even turning on
  • Your computer is emitting a burning or chemical odour.

These actions could also be signs of other, more typical PC issues. It is best to try each remedy individually before concluding that the problem is with your motherboard. 

Even if you think you’ve eliminated every possibility, which can take some time, you should check to see whether there’s a problem with your motherboard’s BIOS. You might be able to fix the issue and save a costly replacement by flashing the BIOS.

Maintenance of the Motherboard:

Assuming they are properly maintained, most motherboards last longer than all the other components of the computer. Heat sinks are designed to move heat away from a computer’s CPU. Even while you shouldn’t need to actively take care of your motherboard, being aware of the typical motherboard killers might be helpful. 

A motherboard can be prematurely destroyed by the following:

  • high temperatures, often brought by by inadequate fans and cooling systems
  • Impact damage, such as breaking your laptop,
  • Using the wrong power accessories or causing electrical damage due to spills
  • incorrect connector types or all the connectors

You probably won’t have these problems if you purchase your computer from a trustworthy manufacturer, take good care of it, and only use authorized accessories and power supplies.


The core circuit hub that enables connectivity between all of the parts and peripherals connected to the computer is called a motherboard, commonly referred to as the “main board.”

A typical motherboard contains the CPU as a basic input output system, memory, storage, (read only memory) ROM BIOS, Southbridge and Northbridge chipsets, cooling fans, peripheral connector slots, connectors for peripheral devices, the battery backup and the power connector.

Like all other technological devices, motherboards eventually break down or stop functioning. There are numerous signs of motherboard failure. Most motherboards endure longer than the other parts of the computer, provided they are properly maintained.

  • You’re probably thinking “what’s a motherboard?” Well, let’s look at the computer as a tool and not just a box with an electronic brain in it.
  • Think about it like this, if you had a friend who was in a lot of pain and needed your help, what would you do? Go buy them an iPad? Buy them a car? No! What you do is you help them and take care of their problem.
  • Now apply that to a PC. Instead of just buying it, you build it and give it to someone else. That’s right – you build a computer for another person. Not just any person, but someone in a lot of pain.

How does a motherboard work?

The motherboard’s functions include connecting every other component of the computer together and supplying power to each one.

The motherboard’s chipset serves as its central processing unit and is designed to work with a specific processor family. What you can connect to the computer depends on the CPU and chipset.

All other components on the motherboard are typically connected to the chipset, with the exception of the primary PCI-Ex slot, RAM (store files), and a few of the sata ports, which are all directly connected to the CPU.

What matters most when purchasing a motherboard?

You must decide on the processor you wish to base your new setup around. Are you securely fastening yourself to the mast of Intel’s magnificent Alder Lake CPUs? 

Or will you still wave the AMD banner with vigour? It comes down to features, overclocking goals, and your budget after you’ve chosen your chip.

How to choose a motherboard for gaming?

When designing a PC with output devices, picking a motherboard for gaming is crucial. Gaming motherboards are more powerful and feature-rich than a desktop computer and laptop motherboards since they are designed for high-performance machines.

Some companies specialise in making motherboards for gamers that have enough room for GPU ( accelerated graphics port )expansion and LED lighting systems, while others concentrate on more commonplace systems. 

Manufacturers of some of the most well-known motherboards include ASUS, Gigabyte, MSI, and ASRock.

What does the ram do?

When you power off a computer, RAM, a type of temporary storage, is erased. RAM provides blazing-fast data access, which makes it perfect for the processes, applications, and programs your computer is now using, such as the data required to use your web browser to visit the internet.

Your computer’s RAM is comparable to the surface of your desk, where you keep everything you need close at hand. Additionally, the information you don’t use frequently or wish to preserve for later is kept on a hard drive, either locally on your device or in the cloud. What ram is compatible with my motherboard? You may maximize your productivity and prevent system slowdown by knowing the recommended RAM memory to install on your computer. Modern Intel motherboards connect CPUs to RAM directly
