Motherboards failure typically diagnoses, because they share plenty of the same symptoms of their components failures. When a motherboard in my current or present laptop dies, then the entire thing shut off and I could not get it to turn on.
So, only one tell-tale sign is if you hit the power button on your laptop and your PC or computer does not turn on or if your PC or computer randomly shuts off. Now, this mightn’t be an immediate indicator that your laptop motherboard dies.
It is also just as likely that your PSU is dead or your central processing unit (CPU) over-heated and your PC or computer shut itself off as a fail-safe. Those’re some things that you will want to check first before you unplug everything from your motherboard.
Although, the simplest way to test your PSU is to plug it into the system that is functioning perfectly and power it on as well. If that does not work, then it was the PSU and not the motherboard.
If you’ve another functional PSU lying around, you can try that on your computer. For laptops, maybe the battery is just completely dead and plug in your laptop with your AC adapter & trying it to turn on respectively.
If that works, then you know the motherboard is incredibly fine. But if your PC or computer still is not booting or randomly shut down, then you might get a beep code when BIOS tries to POST.
Every motherboard manufacturers will’ve different beep codes for various hardware errors, so you will have to check your user manual to know what those codes are since a PC or computer can fail to POST for a variety of reasons. In addition, if your PC or computer does not POST at all and the motherboard’s power light is not on that is another big indication.
Moreover, you will also want to perform a visual inspection to make sure that there’re no bent, and bulging capacitors as that it also a clear indicator that your motherboard has gone to the big repair shop in the sky and if anything smells like burning, so that is another sign.
OK, it is totally dead, now what?
If your motherboard is under warranty, then you can take the motherboard to a repair shop and lets someone else diagnose and replace it for free. Even if, it is not under warranty, then the repair shop can still order and replace the parts for you for a fee.
In addition, you can also do all that yourself at home. Replacing the motherboard in a desktop PC or computer is a lot easier than a laptop, but either is possible. In the case of the desktop PC, you will have to disconnect all the wires and other components.
It is basically the reverse of what we show in our how to build a gaming PC or computer guide. And not to be the bearer of bad news, but if your motherboards fail it is also possible for other components such as CPU to join it particularly if the cause was a power surge.
Moreover, you would not know until you have tested the parts. This’s the part of diagnosing a motherboard failure that can also be frustrating. Swap everything into the new motherboard and do not forget to put the new thermal paste on your CPU.
If everything works great, then you are probably dealing with multiple component failures and could end up having to replace most of the parts. That isn’t usually what happens, but in a worst-case scenario, we have seen the motherboard and PSU failures which cause a chain reaction.
Frequently Asked Questions
What causes a dead motherboard?
Motherboards can go bad for various reasons, although there’re a few common culprits. Among the most common causes of the motherboard, failure is excess electrical shocks and physical damage or excessive heat as well. Some of these dangers are inescapable and may vary in like-hood which depending on your PC or computer model.
Can a dead CPU kill a motherboard?
In a multi-processor system, the death of one CPU mayn’t kill the whole motherboard. In a laptop and tablet system, the CPU is often soldered directly onto the motherboard and may not be fitted in a socket. If a CPU is dead, then replacing the motherboard may be the cheapest solution.
Can the motherboard be repaired?
If your laptop will not turn on at all, it’d be because of a faulty motherboard. But, there’re many circumstances where a motherboard can simply be repaired at the shop.
in other cases, you may be able to replace the motherboard without replacing your other components and saving plenty of money in the process.
Will a PC or computer boot with a dead CMOS battery?
Generally, CMOS battery failure will never stop a PC from booting PC or computer will certainly boot and it’ll stop at the BIOS screen which asking to press F1 to proceed with booting into OS. Due to failed CMOS battery, the system can’t remember the current date or time and revert back to 1 Jan 1900 every time system is booted without a battery.
