Signs of a Failing CPU | Processor Failure Symptoms

Now we are discussing signs of a Failing CPU. The Central Processing Unit is the brain of the computer. It cannot think, but this component in a PC is directing all the actions. It is a tech, and like all the other techs, it can also fail or die completely.

This is like the boss on a computer. It directs all the processes inside the closed body of a PC. The Central Processing Unit s is a marvellous creation of modern technology. It has small transistors on it, and even a single problematic transistor can cause big disasters in the main processor.

Central Processing Unit in the system is the most occupied component of the computer. It is always doing calculations and processing data. While performing its job, it creates heat a lot of heat. Therefore, it is covered with a heat sink and a powerful fan that keeps the CPU cool while the atmosphere gets tense.

Different reasons can cause CPU failure, and by avoiding them, the life of a Central processor can be increased. Before failing, a processor might show some symptoms that indicate that the CPU is in its last stages, and it can fail at any time.

Every computer user needs to know the basic Central processing unit failure symptoms that indicate a central processor’s downfall. This writing piece is written to help you with this matter and enlighten you about a failing CPU’s basic signs.

Symptoms of Failing CPU

There are failure signs that warn you about the condition of the CPU. These signs urge you to take action, or you might end up with a dead CPU. The basic error signs are listed below so you can get aware of them.

Visible Damage

Symptoms of CPU failing

A failing CPU shows it while working on a PC, and also, you can look at it and tell me that there is some problem with it. A physically damaged CPU can lead to a processor failure. If you look on the motherboard and you might see burned marks on and around the central processing unit socket. This is one of the signs of  CPU failure.

Due to overheating, transistors in the main processor can get busted. It might look a little bulging, and this can be an indication of a faulty CPU. If there are black marks on its body, then CPU damage can be the case.

When you start a computer, it initiates a test at the start, which is called the POST test. While the system conducts this test, you hear a beep sound but in case of a system failure. The computer won’t start normally. It won’t display a screen, and you will not hear any beep after the boot.

If the computer doesn’t boot and you don’t hear any beeping sound at the start. The display doesn’t show anything except a black screen; then these can be dead CPU symptoms. Check the indicating LED lights on the motherboard. If it’s  LED light goes off after booting the PC, then it means that you have got a damaged CPU at hand.

Repeated Shutdowns

Motherboards are constantly monitoring heat in the PC. The central processor generates most of the heat generated in the PC. The CPU is the busiest part of the PC, and it creates a lot of heat while working. A fan is mounted on it to prevent it from overheating.

If the fan gets damaged or the processor generates extra heat, to save it from getting permanently damaged, the motherboard shuts down the PC to cool down the processor. If you face the frequent shutdown problem, then check the CPU and its a fan or consult some expert.

Beeping sounds

Like we said earlier, every computer on the startup runs a test called the POST test. POST test checks all the PC components for faults and incases if it encounters a problem with any of the hardware. The motherboard warns the user with some beeping sounds. These are a series of sounds that indicate that some hardware is in error.

The number of beeps indicates the problematic hardware. CPU issues are indicated by 5 to 7 beeps. If you hear 5 to 7 beeps on the PC at the start, it indicates a Dead CPU or CPU failing.

Freeze Screen

This is another symptom of a failing CPU. This symptom of motherboard or CPU failure is rather quite annoying. It is cringy and makes you angry.

After you log into the computer, the PC suddenly hangs or freezes and doesn’t respond to any of your commands. This can be the indication that your motherboards are in ICU condition and can be dead at any time.

Blue Screen of Death

Blue screen death

Nightmare of all the computer users and experts. If you don’t know this or haven’t faced it yet, you are lucky and pray that it stays this way. A Blue Screen of Death is displayed on your screen when there is an error in the PC that cannot be resolved by the PC itself.

It is displayed in case of a serious problem that needs quick action. If you are not an expert or don’t have experience resolving computer problems, you should immediately contact an expert.

If the system’s brain is problematic, and the Blue Screen of Death is caused by it. The screen will display an error with the code 0x00000. This error code is among the signs of a failing CPU or a dead CPU.

Causes of System Failure

We have discussed the damaged CPU symptoms, but the reasons behind a failure are yet to be discussed. It can be damaged due to different reasons, and taking care of them can prolong a CPU life.


CPU generates the most heat in a computer, but it is also the most sensitive part of the computer that can be easily affected by heat. Motherboards have automatic systems that shutdown your computer in case of excessive heat.

CPU or motherboard failure is often caused by excessive heat. If the fans on a motherboard get dusty, they can slow down. Slow fans cannot take out the heat produced by the CPU. So the CPU gets heated up and can damage itself. Regular cleaning of the motherboard can prevent this.

Suppose you want to know the proper way to clean a motherboard. You can refer to our other article about how to clean a motherboard.

Power Surges

Power instability can be a death certificate for any electronics. It can be highly affected by power surges. If you don’t have a power surge protector for your PC, then my friend, you are at risk.

The processor has tiny transistors on it, and an unstable power can fry those transistors very easily. Fried transistors equal to dead CPU. So, Saving it from the power surges is very important, increasing the computer’s brain’s life.


Age can cause death to everything, and a dead CPU due to age cannot be avoided. The age factor cannot be avoided, but it can be delayed. If you take good care of your devices, you can prolong their lifeline, but they can not last long without care.

If you take care of your PC’s brain, it can have a longer life than expected. Life factor is always there after a long period. Everything can wear, but if you want this period to extend, be cautious and take care of it.

Overclocking is the same story. You stress the central processor to its limits and beyond. Stress is dangerous, and who knows it better than humans and especially teenagers. Overclocking increases the power supply to the processor to increase its processing limit.

Many motherboards support overclocking, but it can cause serious damage to the CPU and reduce the component’s life. If you don’t overclock your PC, you can add a lot to its life.


We have given you all the detail about the faulty CPU symptoms. It might show these symptoms before completely failing, or it can die off just like that. It all depends on the cause of the failing CPU.

If the processor shows any of the above-listed symptoms, then contact some expert or contact the manufacturer. These indicate that the CPU is failing, so you can save it from falling if you take action on time.

We have also defined some of the causes of the failure of the CPU. They are avoidable and should be avoided if you want to use them for a long time.

Frequently Asked Questions

How to know if the CPU is dead?

Start your computer, and if your computer doesn’t boot or give any deep sound. If the PC also doesn’t show any screen, it means that your PC’s CPU is dead.
