Central Processing Unit (CPU) or Processor is generally referred to as the ‘Brain of the Computer’. We hardly come across the time when the processor fails but when it does, a common user can’t do anything about it.
So, it is necessary to identify the signs of a bad processor before it’s too late. A normal computer user is unable to revamp the dead processor, but if you successfully get to know the symptoms of a failing processor, you can save it by seeking professional help.
Before discussing the actual problem i.e. the signs of a bad processor, let us first understand the most common reasons for processor failure.
4 Signs Of A Bad Processor You Must Know
The processor of your system, just like the other electronic components, can stop working for the simplest reasons. If you know the actual ones, you can lengthen the lifespan of your CPU by just minimizing or avoiding those issues in the system.
The first & most common reason for which a processor usually fails is overheating. While the system is on, its processor generates enough heat but if it goes above the normal threshold heat value, it may affect the processor badly. This is where you need to understand the role of fans in a system.
#2: Overclocked Processors
Do you have the concept of the clock speed of the CPU? The processors are usually rated based on their clock speeds. The processor designed for the enhanced performance usually has the faster clock speed and vice versa.
But, if a processor has a low clock speed & you are overclocking it, it may fail, due to overstress. So, instead of decreasing the overall lifespan of the processor, you may invest in buying a new one with fast clock speed, instead of overclocking it, which may affect other CPU components.
#3: Unstable voltage issue
If you choose to buy a processor from a reliable brand, it can run for years, without causing any problem. However, if your area has unstable power lines or has the issue of frequent lightning storms; it can make your processor stop working.
The only way to avoid this issue is by using a surge protector for keeping your computer secure from power strikes.
#4: Aging issue
Last but not the least reason for which you can’t do anything is the aging of the processor. Therefore, if your processor is 6 to 7 years old, you can expect it to stop working anytime, even if you are taking care of everything.
There may be different reasons behind its failure i.e. if the fan stops working, it may fail. If one of the million transistors stops working, it may become dead. This factor of processor failure is usually the most difficult one to identify and there’s no option left except replacing it.
A list of symptoms of a failing processor
System booting issues
One of the biggest signs of processor failure is when you power up your system but nothing happens. In this situation, you will not hear any beep as the POST test is not being passed.
This situation is a clear indication of a processor failure (there may be an issue with other system components as well). Just to make sure, you need to open your system to look at LEDs inside.
Turn on your system, if LEDs light up & still system doesn’t respond then your processor is at fault.
This scenario is a definite sign of processor failure. There are a few temperature sensors of the processor on the motherboard.
When these sensors exceed the defined threshold value, the system automatically shuts down. This shutting down process is to prevent the processor from getting severe damage.
In this regard, the best recommendation for you is to eradicate the heat sink off the processor & wipe off the thermal compound layer (older one) & replace it with a new layer. Place the heat sink at its original position & test if the things work properly.
System freezes immediately
Another sign of the bad processor is when you are working on your system, the mouse usually freezes on the screen.
In some other cases, it hangs or the system becomes completely unresponsive when you try to perform some sort of action. It is either the failure of the graphic card processor or a signal to a bad/failing processor.
So, to find out the actual reason behind, you are required to isolate possible systematic components to realize the actual reason causing this freezing.
System abort – Blue screen
This is generally referred to as windows stop error. This blue screen is a clear indication of some hardware or software crash.
The actual cause behind this terrifying screen is General Protection Faults, which is a direct signal to a bad processor, which is about to fail.
But you need to keep in mind that the blue screen is not always the sign of a failing processor. There may be a variety of other reasons behind, such as driver error or hardware component failure.
So, to know the actual reason, here is the best suggestion for you. This blue screen of death always displays an error message in a specific format like this: (0x00000x00000x000000x0000000).
But, unfortunately, we are unable to understand this. So, the solution is to copy this code & Google it to know the exact failing component. In this way, you can take appropriate actions.
Averting processor failure, when it’s showing bad signs:
If you choose to buy the system processor from a reliable brand, it will run at its best for years. The reason is that the processors are made for longer dependability. But, you must take care of a few things to ensure its fullest capacity for a longer lifespan.
The very first thing to take care of is the heat levels of the monitor. It is best to place your systems in a cool environment & make sure the fans inside are working properly.
It will be great for you if you choose to buy third party coolants. Proper cleaning of the internal components, as well as the external ones, is necessary regularly.
Because, the dust particles can be the reason to clog the air vents which can consequently reduce the airflow, which is much needed to keep the processor cool.
