How To Breadboard A PC? [Beginners Step-By-Step Guide 2024]

Written By Farhan Bin Matin

Do you know there’s a way to check your PC hardware parts without actually building the whole PC? It’s called Breadboarding.

Breadboarding is a technique that many advanced computer users used back in the day. Still, some users use it to determine whether a particular hardware component is defective or not.breadboard-a-pc

If you seek to learn breadboarding a PC, you have come to the right place. This post will help you to know everything about PC breadboarding.

So, let’s begin the journey to know how you can breadboard a PC in a watered-down way.

Follow our guide to fix BIOS is updating LED firmware on Asus Motherboards.

What Is Breadboarding A PC?

Breadboarding for PCs is an advanced technique to troubleshoot computer parts. It uses the minimum number of necessary hardware components to determine whether a specific hardware part is defective by hearing the beeping sound from the motherboard speaker. 

Breadboard usually means the circuit board for Digital Logic Design. The picture shows that breadboards are used to put different types of electronics IC, Parts, LED, and Switches to build digital projects.

breadboard

However, PC users around the globe use the word Breadboarding differently. They use it as a technique to test their hardware components before putting them in the CPU case.

Breadboarding is done before building a PC or placing them in the CPU case because sometimes building a PC could take more than a couple of hours. For this reason, breadboarding is used to save time and hassle before putting in defective hardwares.

How To Breadboard A PC

Breadboarding is done with a minimum amount of necessary computer hardware components. For breadboarding, PC components are laid on the ground, and every part is plugged into the motherboard one by one to determine their condition with the help of the beeping sound from the motherboard.

For breadboarding a PC, you will need the basic hardware, such as a power supply, motherboard, processor, RAM stick and other necessary components.

Breadboarding helps to find faulty components when you can’t be precisely sure what is causing the problem.

Computers, as sophisticated machines, sometimes fall into situations where the users cannot find the root cause of the issues. That time the breadboarding is used to find the root.

For example, Breadboarding helps to determine the problem of a computer that won’t beep at startup, won’t show anything on the screen, and generally won’t move into and past POST.

Note: POST means Power-On-Self-Test. It is a series of tests that verifies that the computer meets the prerequisites to boot up properly. In simple words, After the power button is pressed, the BIOS goes through a series of internal tests to check if every hardware is working.

Follow our easy step-by-step guide to fix Monitor goes black for a second.

With the help of POST and the beeping sound coming from the motherboard, you can find and, if not, eliminate the other possible faulty hardware to fix your issue.

Bear in mind that Breadboarding is not a simple technique. It’s an advanced troubleshooting method that only experienced PC users can do.

I don’t recommend breadboarding your PC if you are not experienced with computer hardware because a mishap can damage your hardware components.

WARNING: I will not be held responsible for any harm that the techniques described in this post may do to your computer, hardware, software, and/or data, including any loss of use, data loss, or financial loss.

If you understand and know the possible damages breadboarding can do to your components, you can carry on to the next phase.

Here’s How To Breadboard A PC:

Prepare Yourself

The first step for breadboarding a PC requires you to prepare yourself, and It is necessary to follow the safety precautions.

Since breadboarding is done outside the CPU case, you have to prepare not to get any electric shocks by touching the motherboard or other parts.

Nowadays, many houses don’t have a grounding line, and for this, when you touch your PC’s metal part, you might get a little bit of electric shock.

Most expert PC users are used to getting these shocks, but in some houses, this electric shock has more power and can be painful if you get hit.

Many would say to use an anti-static wrist strap, but if you don’t have that or the time to buy one, you can use some daily products without an anti-static wrist strap.

For make-shift safety, it’s advised to prepare yourself by wearing some dry shoes or sandals and keep in mind don’t wear any clothes with synthetic fabrics.

Also, get non-conductive dry cardboard to place your hardware on it.

Since breadboarding is done on the floor, there’s a chance to get an electric shock from the ground, so get large cardboard to place your hardware components.

This way, you will not feel electricity shocks from touching the computer parts.

Also, check out our separate post on how to ship RAM safely.

Make A List Of Your Motherboard’s Beep Sounds

Breadboarding is a technique where users determine faulty hardware by hearing the beeping sound of the motherboard.

These beeping sounds are similar to Morse code. At first, you will not be able to differentiate the beep sound, but after hearing closely, you will understand that there are intervals or time delays in those beeps.

To distinguish the beeping sounds and understand them, you will need a chart or a list containing the meanings of those beeping sounds, and you can find the list on the motherboard manufacturer’s website.

But I tried searching using the motherboard model but couldn’t find mine. Instead, I had to search by the type of BIOS.

So to find the meaning of beeping codes, you must find out what kind of BIOS you have in your motherboard, and you can look them up online. After that, use the result to search the list of the meaning of those beeps.

Make a list of those beeping sounds.

I Will Give You Some Example Here:

  • One beep during logo display means no errors during POST.
  • Long sounds in a never-ending loop mean no RAM is installed or detected in the system.
  • Three short beeps followed by one long beep means either a missing video card or a memory issue.
  • High-pitched sounds while the system is operating indicate that the CPU is overheating and that the system is operating at a lower pitch.

These are the Award Modular BIOS Post error messages with beeping sounds.

If you cannot find your BIOS beeping sounds list, don’t sweat. I will make a table containing all the beeping sounds at the end of the post.

Go and check our other article on can I use two different brands of RAM.

Prepare All The Components

In this stage, you must prepare all your hardware in one place.

Suppose you just bought new parts, then unpack them one by one and place the motherboard and Power Supply on the cardboard or a dry surface that won’t transfer any static electricity.

If you want to check the remaining part you have, in this case, you have to take them out from your CPU case.

You might wonder why you must take it out of the CPU case. It’s because it would be easier to connect the components when the hardware parts are on a table or the ground.

So, turn off your computer and get a screwdriver to unscrew all the hardware components you need from your CPU case and unhook the cables connected to other hardware, including USB devices, the mouse, keyboard, speakers, etc. Also, take out your RAM.prepare-all-the-components

Here Are The Main Components You Will Need: 

  • Motherboard
  • CPU
  • PSU
  • RAM 

Important: Ensure that you have a speaker with your motherboard. You must need a motherboard speaker to perform the breadboarding technique on a PC. If you don’t have one, Get one online or at a retail shop. It will cost less than $3-$5.

Check out our recent article on is ADATA RAM good.

Connect PSU

Now, you have to install the hardware one by one. First, make sure the motherboard is connected to the Power Supply Unit.

Connect the 24-pin Motherboard Power Connector Pinout of the PSU on your motherboard. Ensure it is properly connected and the pins fit well into the connector.

Also, since you have removed all your components from the CPU casing, you cannot use the power button to turn on the Motherboard/PSU/PC.

For that, you have to jump-start the PC whenever you are trying to power the computer by connecting the two power pins from the front panel connector.

jump-start

All you have to do is touch them very gently with your screwdriver, and to turn the PC off, you can turn off the switch of the PSU.

Install The CPU

You are done with the power supply. Now it’s time to connect the processor.

The processor is an essential part of breadboarding. Without it, the computer won’t start to perform the boardboard troubleshooting.

To connect the processor, you have to ensure it is appropriately connected to the motherboard with its CPU cooler.

If you use a working processor, then it’s good to go. If not, ensure the processor is in good physical condition and all of the processor sockets and pins of the motherboard are not damaged in any shape or form.

The processor should be installed professionally. If not, the processor might get damaged or unusable. So if you don’t know how to install a processor, follow the steps as I state them.

Here Are The Steps To Install A CPU:

  • Locate the lever on the side of the processor socket.
  • Push the processor clips to the lever down to un-clip and lift it slightly to the right side.push-lever
  • Open the load plate with your hands, and do not touch the sockets with your fingers.open-plate
  • Get the processor, and make sure the processor is aligned correctly with the notches (your motherboard should have a triangle in the bottom-left corner that you should align if done correctly, the CPU will fit right into the socket without any pressure.)align-processor
  • OPTIONAL: Remove the plastic load plate if you have any.remove-plastic-plate
  • Press down on the load plate to close and engage the socket lever.close-lever

Apply the thermal paste on the top of the processor and put the heatsink in the right place.

Here Are The Steps To Install A CPU Fan:

  • Take the CPU Fan with the heatsink and carefully align it with the fasteners through the holes.connect-fan-cable
  • Push down on the top of each of the fasteners in an alternate pattern, and You should hear a click sound while pushing down the fasteners.push-down-fan
  • Twist the fasteners to lock them in the direction marked on the body.lock-fans
  • Connect the processor’s 4-wire fan cable connector to the motherboard 4-pin CPU fan socket.connect-fan-cable

You can turn on the computer by jump-starting. If the motherboard has AMI BIOS and starts beeping with 5 Short Beeps, it means the processor has an error which means the CPU needs replacement, but there is also a possibility of a CPU Socket problem.

If the motherboard beeps continuously, it means the processor is fine, but no RAM is detected in the system.

Install The RAM

You have to install the RAM right now.

Installing RAM is pretty easy, and anyone can do it without help from others.

Get the RAM stick on your hand and find the notch on its body.

If you look closely at the motherboard’s RAM slot, you will see that it has the same notch as the RAM. You have to align them properly and put them into the right place to install RAM.

Here Are The Steps To Install A RAM:

  • Press down on both clips on the sides of the module to unlock the clip.ram-slot
  • Take the RAM and align it correctly with the notch.align-ram-notch
  • Place the RAM and press it until the clip is fastened.press-ram

You are done with installing the RAM. If you start your computer now, then you will not hear the constant beeping of undetected RAM, Indicating the RAM does not have any fault.

Install The GPU (Optional)

This step is optional, If you have any extra dedicated graphics card, you can follow this step, and if you don’t have any, you can skip this one.

Here Are The Steps To Install A The Video Card:

  • Locate the PCIe X16 slot on the motherboard.pcie
  • Open your PCIe slot lock by pulling down a bit.unlock-gpu-slot-lock
  • Align the GPU with the slot.
  • Install the Graphics Card by pushing it down.insert-gpu
  • Connect the power supply with the GPU.gpu-power-connector

Note: Some of the GPUs need extra power connectors to power them, and some older GPU models don’t.

Turn the PC by jump-starting and hear the beeping sound to determine if the video card is OK or it’s defective.

If the GPU turns out to be defective, you will hear the beeps depending on the BIOS.

Install Other Hardware

Install the other hardware individually to determine whether the hardware component is OK.

By hearing the beeping sound, you can find any defective hardware in your computer, so observe the beeps closely and go through the list of beep noises for what those beeps mean.
