There are some situations where a processor or even a motherboard may suffer due to a malfunctioning power supply. Even using a processor or motherboard with a certain level of damage can be a wrong decision. This could create more problems for the rest of the components in a PC.

So it is essential to know a way to detect if a motherboard or processor is fried. Of course, it is necessary to have a computer expert to repair all the damages found. Before that, there are some ways to know if these components have an inevitable deterioration. That is why we recommend reading the following information to be more attentive.

How to Tell if a CPU is Fried? 

It is possible to tell if the physical damage on this component fries a processor. One of the first steps is to unplug the computer to avoid any electrical accident. It can be beneficial to analyze the physical part of the processor, just as we could do with the motherboard.

It is essential to remove the side panel or the plastic bezel if it is a laptop. It is also necessary to remove the keyboard if the back cannot be removed if it is a laptop. In general, when dealing with a fried processor a few minutes ago, the user may smell smoke.

In any case, it is necessary to consider that the smell of smoke may be present when the processor or some other component of the PC has been burned. Some of the circuits or the structure of the processor itself may show signs of charring. Beyond that, it is essential to check the structure of the processor and the surrounding components.

Many computers usually have capacitors that are also very likely to be damaged when a power supply fails. Capacitors are responsible for filtering electricity and maintaining a proper balance to power the different components. One of those components is the processor. Therefore, if the capacitors fail, it can affect the processor itself.

Capacitors have a cylindrical shape and can easily suffer from overheating or excessive voltage surges. To complete the physical damage check, electrolyte breakage or leakage must be detected. 

Another problem when the processor is fried is that the PC does not turn on. Before checking if the processor is the problem, it is essential to analyze a power cable that has been damaged for some reason. It could also be that a surge suppressor is turned off.

Checking the configuration of this power component is essential. The computer may not turn on if the processor is severely damaged or the power supply is not configured correctly. Some configurations may be set to 220 volts when only 115 or 120 volts are needed.

The processor is one of the central parts of the computer. However, the user may still encounter a significant obstacle when performing any activity on the PC. Some superficial damage to the processor may allow the computer to turn on anyway. It may also happen that other components work, such as fans, without the processor working.

How to Tell if a Motherboard is Fried?

When a motherboard is damaged, there can be some obvious signs of deterioration. Diagnostic sound codes can be helpful to be able to detect if the motherboard has been damaged. A partially damaged motherboard may have problems in only one of its connected components.

So the problems that we can find on a PC can be related to sound or graphics. When the user detects some inconvenience in the motherboard’s sound, this is a clear sign of partial damage to the motherboard. When the motherboard is damaged or fried, the computer may also not turn on.

In this case, it is also advisable to remove the side panel of the PC and look for signs of burning or charring of the motherboard. A burning smell is also another noticeable characteristic and is present in these situations. The video clip may also be fried when the PC screen only displays random characters for a few moments and then stops.

The motherboard can exhibit this issue when it has suffered some water damage. Of course, the damage is even worse when the motherboard has gotten wet and has not completely dried out by the time it is used again. So if a PC has gotten wet for any reason, it is essential not to turn anything on for any reason.

Tips to Keep Them Safe from Dead or Damaged

As mentioned above, it is necessary to have the correct voltage when using a PC. The voltage used in a computer can vary depending on the geographical area in which the user lives. As the number of components in a PC increases, the voltage is also another factor that can vary.

Considering the correct voltage for using a PC is one of the most important aspects to keep each of the components protected. The same applies if a PC or any of its components have gotten wet.

The user should not use his PC unless each of the components is completely dry. Damaged components should be replaced to prevent failures from affecting other components.


Checking the condition of a processor, a motherboard, or any other component is essential at all times. These are some of the main components that any PC needs to function.

At the same time, the compatibility and voltage of these components should be checked when a user is building his PC. All this will be able to avoid any partial or total damage that can be costly.
