A motherboard is the main circuit board of the computer and is also called the mainboard or logic board. When you open your computer, the largest piece of silicon is the motherboard. You will find CPU, ROM, memory RAM expansion slots, PCI slots, and USB ports attached to the motherboard.
This also includes controllers for devices such as hard drives, DVD drives, keyboards, and mice. The motherboard is what makes everything on the computer work together. Each motherboard has a collection of chips and controllers called a chipset.
When new motherboards are developed, they often use new chipsets. The thing is that these boards are generally more efficient and faster than their predecessors. The bad news is that older components often don’t work on new chipsets.
Of course, if you plan to upgrade several components, it may be more cost-effective to buy a new computer. Here are some common motherboard problems and a guide on how to fix Motherboard in 2022!
What are the Symptoms of a Bad Motherboard?
How do test if the motherboard is faulty? To determine if your motherboard is bad or broken, there are some key things to keep in mind.
1. Blue Screen
One of the most popular signs of a failed motherboard is the blue screen, commonly known as the blue screen of death.
The blue screen of death is caused by a hardware failure in the computer system which prevents the operating system from working at a safe level.
It’s not a sign of complete failure, but it does mean that some computer component is nearing death.
You may be familiar with the general speed of your computer. If it works slowly and your computer slows down, it could be a symptom of a motherboard failure.
It can be slow when multitasking or running memory-intensive programs, but it can also be slow when performing simple tasks like typing.
3. Faulty or Stopped
Does your computer seem to freeze and all icons are disabled? Well, this could be a sign of a dying motherboard.
Sometimes the computer freezes due to memory load, but frequent hangs even when the memory is not loaded is a bad sign.
Connected external hardware can cause your computer to hang, so you can remove it and see if they hang persists.
4. Hardware Damage
Like other electrical devices, computer motherboards come with capacitors and transistors. Problems with electrical connections can cause short circuits and ultimately burn these components.
Although you cannot physically see it because of the computer case, the smell of burning is one of the main symptoms of a faulty motherboard when it comes to short circuits.
If you experience any of these symptoms, immediately turn off the computer and disconnect it from the power supply to prevent the motherboard from completely dying.
5. Hardware Recognition Failure
You can overlook this issue, but it could be a sign that the motherboard is faulty. Computer motherboards are designed to recognize common hardware such as external hard disks and flash drives.
If the computer that was recognizing this hardware stops recognizing the hardware after rebooting, it may mean that the motherboard is dying.
However, faulty external hardware can also cause problems, so you should test with different hardware or test the hardware on a different computer to determine if the problem is the motherboard.
This issue can render your computer unusable, especially if your mouse, keyboard, or monitor cannot be recognized.
Overheating is not only a cause of mobo errors but a common symptom of motherboard problems. Computers generate heat when running, so it is normal for the computer to get warm.
Your computer can overheat when running intensive programs such as games, but not when performing simple tasks. If your computer overheats when idle or running simple programs, it could be a sign of a faulty motherboard.
How to Fix a Dead Motherboard Common Problems?
How to fix the faulty motherboard here are some most common motherboard problems. Let’s take a look at problems and how to fix them.
1) Lack of Power
This problem is easily solved by purchasing a better power supply cable. If that still doesn’t work, there could be another hardware issue preventing the system from turning on properly.
Such as a dead RAM stick or a defective processor. The only way to know for sure is to open the case and look inside (if you’re comfortable).
2) Frequent Crashes
The motherboard may not be able to handle the voltage output of the power supply. If you have an aftermarket CPU cooler, such as a water-cooled system.
You might want to consider buying a better PSU that offers more power. Another thing that can cause problems is connecting too many devices at once.
Unplug everything except the CPU and video card (if present). If that doesn’t help, you may need to disable some startup programs or invest in better hardware.
3) Loud Squeaking Sound when Starting
The only way to solve this problem is to buy a new fan for the case. You will need to put a more powerful fan in the case while doing this.
This is because the primary fan may not be very effective at cooling an already overworked motherboard.
4) Computer Turns off Randomly
You need a better power supply. Most standard power supplies have this problem if the computer shuts down randomly while using it.
The only way to solve this problem is to buy a better PSU and make sure it never happens again.
If you have an aftermarket CPU cooler, such as a water-cooled system, you might want to consider buying a better PSU that offers more power.
Another thing that can cause problems is connecting too many devices at once. Unplug everything except the hard drive, monitor, and keyboard.
The third (and probably least likely) cause of this problem is a short circuit on the motherboard.
If it is an old motherboard, we recommend that you buy a new one.
5) Computer Does not Turn on
If you’ve done all of the above and you’re still having trouble turning on your computer, you may have a broken power supply. I know what you’re thinking. How could that be? If connected to electricity it will not work!
Just because the PSU button light turns green does not mean that the motherboard is getting enough power through the wiring.
If it’s a standard power supply, it’s better to buy a better one so you don’t have to replace it again after 6 months.
6) Computer Turns on but Cannot boot into Windows or other Software
This can happen because the computer is trying to boot from an external device (eg a flash drive). Turn off your computer and try unplugging all non-essential plugs to see if this helps the problem.
If that doesn’t work, you may need to contact a Melbourne computer repair professional.
7) Computer Keeps Turning off while Running
This again can be caused by a bad or inadequate power supply, so replacing it with a better one should solve the problem. If this does not work, continue to step 7.
8) Computer is Running Slowly, Freezes Randomly, Crashes Frequently
Overheating is a very common cause of these issues causing hardware failures or slowing down your system. For about $10, you can buy an external fan that attaches to the outside of your computer case and blows cool air inside.
If that doesn’t work, you may need to replace overheated components like the CPU and GPU. Note: Make sure you have purchased replacement parts for your computer.
9) Computer Turns on but doesn’t Show anything to Monitor
This can be caused by several different issues. If this does not solve the problem, the motherboard may need to be replaced.
This issue may also be resolved by reseating the RAM (carefully plugging and unplugging it into the socket, then powering it back on). If neither works, there may be a problem with the video card or power supply.
10) No Video
The computer boots up fine, but no pictures or videos are displayed when using a different monitor, or cable (fan spinning sound, etc.). This can be caused by several different issues and is detailed in the article here.
First, make sure all connections are secure. Make sure the video card is properly seated on the motherboard and there are no bent pins on the card or the socket itself.
Make sure all power cables are securely connected to the video card and motherboard. If that doesn’t work, you may need to replace your video card. If neither works, there may be a problem with the RAM or power supply.
11) When I Turn on the Computer, a Black Screen Appears.
The first step is to ensure that the video cable is securely connected to both the monitor and the video card/onboard graphics adapter (if applicable).
The next step is to re-seat (connect and disconnect several times) the video cable to the video card. If that doesn’t work, try booting the computer with only 1 RAM.
If you still see a black screen, power cycle the monitor several times. If these steps do not resolve the issue, there may be a problem with the motherboard or power supply.
12) My Computer does not read Audio/Video Files
You will need to reseat (connect and disconnect multiple times) all audio/video cables, including network cables, if applicable.
If you have ensured that all cables are securely connected to both devices and that no foreign objects are interfering with proper connections.
You need to make sure your audio device is set as the default device. This can usually be done by right-clicking on the sound icon in the system tray and selecting “Playback Device”.
From there, make sure your primary device is not muted or set to an alternate audio source. If it still doesn’t work after all these steps, then most likely you need to reinstall the application (sound/video codec).
13) My Computer won’t boot past the BIOS Screen
If these steps do not resolve the issue, consider resetting the BIOS. To do this, turn off your computer. Now turn it back on.
However, if something appears on the screen (before you see anything), press F2, go to settings or delete it repeatedly until prompted to exit.
After accessing the BIOS settings, find and select “Load Fail-Safe Defaults” or something similar. If the BIOS gives you an option, you will be asked if you want to do this.
Choose Yes or OK. This will reset the BIOS to the factory default settings and your computer should now boot properly again.
If not, there may be a problem with the hardware itself, and further troubleshooting may be required, especially if automatic recovery is interrupted.
14) The Computer is having Trouble Waking up from sleep or waking up after Sleeping
This is a common problem with laptops/PCs, but it can also affect desktop computers. There are several ways to solve this problem, depending on what exactly the problem is, but here are some tips.
1. If the computer is having trouble turning on after sleeping, try restarting the computer and then continuing to press the power button. Sometimes this can put something back in place and cause it to reboot properly.
2. If you are using a laptop, turn off Hybrid Sleep in Windows. This puts the computer in a deep sleep state, which can cause problems when you try to turn the computer back on.
Also, make sure you are not running any software that automatically puts your PC to sleep, such as an energy-saving program. Finally, make sure hibernate is not enabled in your BIOS!
3. If none of these work or apply to you, go through all your device drivers and temporarily disable them one by one. Once you find the culprit, you’ll almost certainly know that your computer works fine without the culprit.
4. Resetting the BIOS to default settings may also help, but do this only as a last resort! Hardware issues related to power on can be resolved by resetting the complementary metal-oxide-semiconductor (CMOS).
Which is usually done with a jumper pin or button on the motherboard itself. If that doesn’t work, it’s time to have your motherboard repaired or replaced.
5. But if all else fails, the motherboard (or at least the power management system) needs to be replaced. Motherboard replacement/repair is time-consuming.
In most cases, it’s best to take your motherboard to a professional for repair. Solve the problem yourself, only as a last resort. However, in general, simple problems such as power problems can be solved on your own with little difficulty.
So far, we’ve looked at how to troubleshoot some basic issues that people often experience with their motherboards. However, these are by no means the only common motherboard problems.
The experience gained with replacing the motherboard offers the possibility of using the same computer for 10 years (or more) by replacing internal parts when needed.
The issues mentioned above are common with reckless solutions that will test your patience but will ultimately work.
This means that if you feel like your problem has been resolved, you can always consult a professional, whether you bring your computer to a certified technician or call the manufacturer.
