How do you know if the motherboard is burnt?

To know if your motherboard is burnt, you must first try to identify some problems that can cause a component in your computer to fail. These include dirt build-up, overheating, installation error, among others.

Therefore, in this article, we will help you recognize these signs, because the solution can be very simple and even prevent the motherboard from burning out completely. Check it out.

What is a motherboard?

You must first understand the concept of a motherboard to understand how this type of problem can prevent your computer from working. The motherboard bears this name because it contains all the components for good work, that is, it unites all the parts and ensures the passage of information between them.

Even the power supply is eventually connected to the motherboard, because it has the function of transferring that energy from the power supply to other peripherals in the case. This means that without the motherboard, no component would communicate with the other, and the computer would not work. In a broader analogy, the motherboard is like a conductor at a concert.

Problems that can cause damage to the motherboard


Since the motherboard has such a wide function, when there is a problem related to it, there can be several factors for it. Here we’ll list some of those factors and how you can check and fix them if they’re causing your computer to malfunction or even prevent it from turning on.

Check the position of the board

A poorly installed board can become a problem as it becomes loose and can end up touching other structures. When dealing with metal structures, such as the metal base of the case, for example, this eventually creates a short circuit. This causes the computer to randomly crash or even not turn on, and in a more serious case it can cause the motherboard to burn out.

In addition to the bad position of the motherboard, another reason that leads to a short circuit on it is the presence of bare wires in contact with its surface. Therefore, the solution in this case is to first check whether it is well adjusted and properly fixed in the brackets. If necessary, you can take it out to put it back in, making sure the screws are tight. Also look for any loose cables near the card, and if there are any, arrange them so that they are not touching the card.

Prevent the accumulation of dirt

Although it may seem very simple, the process of physically cleaning your computer can be very important. This is because dirt build-up between components eventually prevents air from circulating between them, consequently causing heat build-up and overheating.

This can affect the performance of these components and even cause irreparable damage, such as burning. In this case, it is recommended to clean the cabinet at least every 6 months. If you have a vacuum cleaner, you can use it on minimum speed. If not, you can use an isopropyl alcohol wipe. You can also use a brush with soft bristles to remove dirt, but do not blow.

Look for computer cleaning kits, sold at electronics stores, to make sure you’re using the correct materials.

Besides dirt, other reasons can lead to overheating.

Overheating is one of the main problems that can cause a motherboard to burn, so you must avoid it as much as possible. But besides the accumulation of dirt, there are other causes of overheating.

One of them is to put the case in a poorly ventilated place, which is naturally hot, especially if it is cramped. So there will be no air to circulate, and the ambient temperature will affect the temperature of the components.

Another cause is careless overclocking. When overclocking, you must pay attention to the temperature of the computer components, and if there is an increase, cancel the procedure. For this, it is possible to use some programs that are dedicated to measuring the internal temperature of components such as the processor and GPU. Generally, if this temperature stays above 60 degrees Celsius, it is a warning sign.

Pay attention to the power supply and the cable

Many people don’t care too much about the font when building a computer, but that can be a mistake. If there is not enough power to guarantee power to all computer components, it will not turn on. One way to get an idea of ​​how much power your computer needs is to check out sites like the OuterVision Power Supply Calculator.

In this case, two tips apply:

Always check the power cord connection first. Or they may not be properly seated or even loose. Almost every motherboard has 2 power inputs, one that has 24 pins, which is the largest, and a smaller one that can have 4 or 8 pins, and you have to connect both. And if you have a dedicated graphics card, chances are it has an 8-pin input as well. If it’s plugged in correctly, it’s worth unplugging it and plugging it back in to make sure nothing is loose.

Second, if your computer won’t turn on, the problem could be right at the source. So if possible try to change the font and turn it on. Many people end up assuming that the problem is with the motherboard and miss this detail.

Make sure all components are installed correctly

The reason why the computer has problems or even does not turn on can be a bad installation of a component on the motherboard, which eventually does not recognize it or affects its operation. It is worth checking in particular whether the video card and memory are properly installed and placed in the right place. If in doubt, unplug it and plug it back in.

How do you know if the motherboard is burnt?


If you’ve tried all of these solutions and the computer still won’t turn on, then it’s likely that the motherboard is burnt. However, this is not certain. For those who don’t know much about computers, it is ideal to take it to a technical support, because they will have the right tools to identify if the motherboard is really burnt or not.

One of these tools is a multimeter, which measures direct and alternating current and resistance. It is not a very expensive tool, but you still need to know how to use it. You can also do a test with the speaker, removing the memories to see if the motherboard will identify the lack of those memories. And you can still look at the capacitors to see if any of them are blown.

If it is really burnt, the best option is to buy another one. Although in some places it can be repaired, it is not worth it because the warranty will be very short.
