Motherboard Failure – Guide to Analyse Signs 2023

In this article we will put light on the reasons that leads to motherboard failure and also analyse the motherboard failure signs.

So, there is a possibility that the problem lies in the motherboard of your computer if it stops working abruptly or maybe not so suddenly. Unfortunately, they are also one of the computer components that are among the most difficult to repair or replace.

Not only is the motherboard typically one of the more expensive components on the device, but if you need to replace it, you typically need to replace the central processing unit (CPU) and the memory as well an expense that can mean purchasing an entirely new computer would actually be the more cost effective option.

However, before you go digging through your wallet for your credit cards, there are a few things you should be sure of, since the fact that the board seems to be dead may in reality not be the case. I will demonstrate how to identify issues with the motherboard, as well as provide you with a few replacement options if the board is damaged beyond repair.

Motherboard and its Functionality

Let’s have a quick tutorial about the components of a personal computer and where the motherboard fits into the scheme for people who didn’t grow up building computers and who haven’t learned the architecture of these ubiquitous machines.

This will be helpful for people who haven’t built computers since they were young and who haven’t learned the architecture of these machines. The CPU, the storage (including memory and permanent storage as well as other forms of storage), and the input/output (I/O) system are the three fundamental categories of components that make up a computer both conceptually and physically.

Your central processing unit (CPU), most likely a microchip manufactured by AMD or Intel, and your graphics processing unit, if you have one, make up the processor. Your random-access memory (RAM) and any hard drive(s) that you have are the storage, which is where you place the information.

In conclusion, the input/output system is comprised of all the components that enable you to communicate with the computer, such as the video card, the monitor, the keyboard, the mouse, and so on.

The question now is, what role does the motherboard play in this system? The motherboard may not be intellectually significant, but it is unquestionably essential to the functioning of the computer. All of these additional components are attached to the circuit board, which is basically a collection of circuit boards that have been assembled into one large board.

The central processing unit (CPU) is connected to the motherboard through a connector called a “bus,” which allows it to interact with the other components of the computer, including the hard drive, the memory, the keyboard, and so on.

In most cases, the memory is installed directly into the motherboard. Although the hard drive is likely to be situated in its own location, it will still link to a hard drive controller that is, you guessed it, installed on the motherboard. The USB ports and the keyboard are both hardwired into the motherboard of the computer. In most cases, the video card has its own dedicated bus and connects directly onto the motherboard.

Because it serves as the foundation upon which the rest of your computer is built, it is referred to as a “motherboard,” much like a mothership. No motherboard means no computer.

Initial Alert Symptoms of Motherboard Failure

If your computer begins to malfunction, there are several early warning signals that a component is failing (most of the time). Here are some things to watch out for when purchasing a motherboard:

  1. The motherboard does not identify or display peripherals.
  2. Peripherals will cease to function for a few seconds or longer.
  3. Slow boot-ups might signal that your motherboard is failing, yet it could be be another component (more on this below).
  4. The computer does not detect flash drives, and the monitor sometimes displays weird lines (particularly relevant if you have onboard video on your motherboard).
  5. Motherboard does not POST (Power on Self-Test).
  6. A burning odour or burn marks on the motherboard itself.
  7. Capacitors that bulge or leak

Signs of Faulty Motherboard 

Following is some of the symptoms of a failing motherboard:

1) Failure to boot

When you push the power button on the bottom of your laptop or computer, it fails to load and displays no display. This might be due to a motherboard issue.

2) Blue Screen of Death 

When you start your computer, if it displays a blue screen with failure warnings and error codes, there might be issues with numerous components such as RAM, HDD, and even the motherboard. Some motherboard manufacturers will also indicate the source of the issue.

3) Computer Freezes or Glitches

When you first start your computer, it will operate correctly, but as you continue to use it, it will freeze. There are several reasons of computer freezing. It might be a problem with software or hardware.

If this freezing occurs often, there are more significant issues in the motherboard. And you’re probably not aware of the situation until it’s too late.

4) Abnormal CPU Restart

Your computer may restart unexpectedly from time to time owing to insufficient power delivered by the motherboard to various components connected to it.

Your computer may restart suddenly for a number of reasons, including power supply issues, malicious malware, overheating, or driver issues. Among the reasons include heat-related issues, dust, grime, hair, and even viruses.

5) Unrecognized hardware

Sometimes hardware such as USB ports, Audio ports, Mouse ports, and other internal components such as RAM, CPU, Graphics Card, CMOS, and BIOS cease working correctly due to insufficient power. It might indicate a defective motherboard.

6) Reduce performance

If your motherboard is too old, the performance of your computers may suffer. For example, your computer may take a lengthy time to start up.

7) Insufficient power and data speed for the component

If your motherboard cannot transmit adequate power and data flow to the different components, your computer may sometimes cease operating, and the speeds of the CPU and motherboard-attached fans will slow down.

8) PC abnormally overheats

Sometimes the PC overheats excessively, and you will notice that the laptop is hotter than usual.

9) Strange Beeps from the PC

We may diagnose the issue in the hardware using the beep patterns in your BIOS.

Repeated beeps in the Award BIOS indicate a memory problem. There may be issues with the motherboard’s memory or memory slots.

10) Burning odour from the Motherboard

If your laptop or PC emits a burning odour, this might be a sign of a faulty motherboard. In the case of PCs, remove the CPU shell and inspect it from the motherboard.

Follow our guide to How To Diagnose a Bad Motherboard

11) Punctured and bulging capacitors

First, open your PC’s or laptop’s case, and if you see capacitors in the motherboard are pierced and bulging in size, your motherboard is more likely to be destroyed sooner.

Also, if the motherboard’s capacitor is burned and discoloured, your motherboard is more likely to be damaged.

12) Motherboard Twist

When you open your PC’s casing and discover that the motherboard is bent owing to a variety of factors such as overheating, physical damage, and so on, it might destroy your system.

Mechanical overstress or heat shock may cause a PCB board to shatter.

13) Identifying the Issue

You may use some simple troubleshooting procedures to detect whether your motherboard is failing. The troubleshooting process is divided into two sections below: 1) What to look for if the computer still passes the POST and boots (or tries to start), and 2) what to look for if the computer no longer passes the POST or does not turn on at all.

Programming Signs of a Motherboard Failure

If your computer still powers on and boots into the operating system, you should first rule out other hardware components to ensure they aren’t producing the symptoms indicated above.

1) Hard disk(s):

Is it taking a long time to transmit files? Are you encountering any issues or blue screens? Has the startup time risen noticeably? Is there any clicking or loud whining going on? If you answered yes to any of these questions, your hard disc may be failing. It is advisable to run the diagnostic software provided by Windows and/or the drive’s manufacturer. See also our related post, Hard Drive Failure: Warnings and Solutions.

Is the display jumbled, or do you see artefacts on the screen that you didn’t notice before? Do graphically demanding activities result in blue screens or instability? If this is the case, your video card may be failing and will need more testing. For further troubleshooting, visit our article on video card failure symptoms.

2) Memory (RAM) failure:

Even though it has no moving parts, it is possible that your memory will fail, causing your system to crash or become unstable. In this instance, using a diagnostic programme such as Memtest86 or Memtest86+ for additional troubleshooting is suggested.

3) Processor (CPU) failure:

Although uncommon, CPU failure may cause system instability. Downloading and executing the Intel CPU Diagnostic Tool if you have an Intel processor may reveal faults with the processor itself. Try the AMD system monitor tool for AMD processors.

4) Power Supply (PSU) failure:

 A faulty or inadequate power supply (or one that is operating outside of specifications) may rapidly cause a system to become unstable and possibly harm other computer system components.

Make sure you have the correct power supply for your system, and double-check the voltages to ensure they are working at their rated output (the voltages can easily be monitored in the BIOS or in software utilities supplied by motherboard manufacturers). If you’re still not sure, please read our article on power supply troubleshooting.

5) Motherboard BIOS Updates:

A motherboard BIOS update may resolve many system issues (especially on newer hardware). For further information, please visit the manufacturer’s support website.

6) System Over heating:

In many cases, mistakes occur as a result of incorrect cooling or even cooling failure in a computer system. System instability may occur if any of the system’s components are functioning outside of specification owing to overheating.

Go through our epic guide on How to Choose a Motherboard

A visual assessment of the system is recommended to ensure that all components are correctly installed and adequately cooled (i.e., case and component fans are operating normally). Temperatures may also be checked for irregularities inside the operating system using a number of applications; we recommend a few free ones in our article on PC temperature monitoring.

Frequent Steps to Troubleshoot a Motherboard

Knowing, how to diagnose a bad motherboard is a complex operation due to the various components that are linked to it, making it difficult to determine the precise source of the issue.

If you have experienced problems such as the emergence of an error code, the creation of beeps, system locking, an unexpected restart, a BSOD error, ports that do not operate, or memory modules that fail.

Check out the troubleshooting instructions for your motherboard, which are listed below.

  • Check to verify whether your motherboard is receiving enough power. Examine the voltages going from an external source toward the power supply and determine whether the fan on the power supply is operating. Examine the quantity of electricity delivered to the motherboard.
  • Verify that the power supply connections for all relevant components are connected to the motherboard.
  • Examine the BIOS and UEFI settings, paying special attention to the CPU fan speed and temperature in the BIOS.
  • First, open the CPU cashing and search for the capacitors. If a bulky and damaged capacitor is there, you may find it.
  • You might try reinstalling and reseating the CPU, and you could also check to see if the CPU’s pins or socket are filthy. If you answered yes, please clear it up and try again.
  • Examine the CPU to determine if any pins are damaged. In this instance, a known good CPU should be used instead.
  • Reinstall the memory and double-check that it is fully installed.
  • Reinstall all peripherals such as the GPU, keyboard, mouse, HDD power supply and data supply cable, graphics card, network card, and so on.
  • Examine your CMOS battery.
  • Pay attention to the beeping sound made by the computer as it powers up.
  • Launch Device Manager and search for available devices. If there is an issue, it will be shown.
  • If available, update your BIOS.
  • If the pixels on the screen are pixelated in an unusual way or if abnormalities appear sporadically, it is quite likely that you are having video problems. If that’s the case, check for the Graphic Card and GPU unit.
  • 13 Instead, if you are not an expert in the topic, you should seek their opinion.

How To Retrieve Lost Data After Motherboard Failure

Another approach to provide technical help, this one with small technicians attempting to retrieve data from a hard disc.

You are in for a real treat in terms of retrieving data from a computer with a malfunctioning motherboard. If it was a dead hard drive, you would probably have to submit it to a data recovery firm, which would cost you hundreds or possibly thousands of dollars to recover your data. This would be necessary if you wanted to get your data back from the dead drive. And that’s assuming that your data could ever be retrieved in the first place.

Check out our expert-recommended Windows 11

Obtaining a replacement motherboard and reassembling the computer are the only steps required to retrieve your lost data. However, after plugging in your older hard drive, you will need to change the settings in the BIOS to make it the device that is used to launch the computer. Following that, all of your data should still be there when you power up your computer.

You also have the option of purchasing an adaptor that will transform your internal hard disc into an external hard drive. After that, you can simply connect it to another computer by using the USB cable, and all of your data should be accessible.

FAQs About Motherboard Failure

What happens if a motherboard fails?

Since the computer is the motherboard, a broken motherboard usually means that the whole system is dead. If the motherboard is dead, fans, drives, and other parts of the computer may spin up, but most of the time, nothing happens when you turn on the power. There were no beeps, lights, or fans.

What causes motherboard failure?

Changes in electricity and voltage. Dust particles, smoke, debris, etc. Liquid damage. My fan broke because it got too hot.

How do I know if my motherboard is damaged?

The computer might start to boot up, but then it might turn off. When motherboards are failing, there are more Windows errors or “blue screens of death.” The computer may freeze up for no apparent reason, or devices that were working before may stop working all of a sudden.

Can a damaged motherboard be fixed?

When this happens, many people who own laptops think they need to buy a new one. But there are many times when a motherboard can be fixed without much trouble. In other cases, you might be able to replace just the motherboard without having to replace any of the other parts, which would save you a lot of money.

What is the lifespan of a motherboard?

If you take care of your motherboard and keep it clean, it can last up to 20 years or even longer. The hardware that works with that motherboard will become outdated, so you may need to upgrade to newer hardware, but the motherboard itself should still work fine.
