How to know if the processor fails and how to fix it

The Central Processing Unit (CPU) is considered to be the heart of a computer system. Whatever the title of this note, it is very rare for the processor to fail, and if it does, a normal user cannot do anything about it. The purpose of this post is to teach the user what to look out for, instead of giving the failing processor a few steps to get him back to work. If you are looking for a more technical guide to resuscitating a failed processor, we recommend that you look for other guides.

In this article we discuss the following topics:

  1. Symptoms of processor failure
  2. Processor failure causes
  3. Troubleshooting a faultyprocessor
  4. How can I prevent theprocessor from failing?

Before we start on the main topic, we would like to remind you that we accept requests for help with your Windows computers. If you have a problem for which you don’t seem to find a solution, please send it to us by clicking on the link at the bottom of this page. Remember that window problems are sometimes difficult to diagnose, so try to give us a very detailed description of the problem. You want to mention the relevant story that may have led to this problem. The more information you provide, the better chance we have of diagnosing the problem. We also expect you to include in our article any steps you may have taken to correct the error before contacting us to prevent it from happening again. It’s the same here: The more details you give us, the sooner we can find the cause and the solution.

Symptoms of processor failure

Modern computers don’t boot the operating system if a component as important as the processor doesn’t work. In other words, a normal boot process cannot be completed because the POST or the self-test on power-up indicates that a critical component is missing in the system. Other components such as the fan, the hard disk and the motherboard as a whole will continue to work, but the boot process will eventually end with a blue screen of a fatal error. However, other symptoms have been observed before and during processor failure, of which you should be aware. Their knowledge will help to identify the problem more quickly and reduce downtime.

Locking and overheating shortly before turning off the PC. If you find that some cases of your computer are locked before the final crash, you should consider, among other things, a bad processor. The system may have overheated, so it automatically shuts down to prevent further damage. The processor has a built-in fan to cool down, but if the fan fails for any reason, the processor may temporarily overheat. This is one of the reasons why you should ensure that all fans in your computer are checked and cleaned once a year. Sometimes dust can suffocate the fans, so regular maintenance can damage the system. If your processor seems to overheat regularly, clean the fan first. If this doesn’t work, check the BIOS to see if you can reduce the speed. This can have a significant impact on performance, especially if you use your computer for graphic purposes, but it can also be the only effective way to do this, let alone replace the processor.

Keep in mind that prolonged overheating can permanently damage the processor. If you are 100% sure that your processor is overheating (some motherboards have diagnostic tools that allow you to check the temperature of the processor), find a way to lower the temperature or contact a specialist to find out how to solve the problem.

Sneeze. As mentioned above, your computer performs a self-test (POST) to determine whether or not all of your important peripherals are working. If the test detects that the CPU is not working, the boot process is interrupted and the motherboard beeps. The beeps are actually codes that help the technician identify the problem, so be aware of how many beeps there are. Then you can find it on Google, i.e. the beep code.

Burn motherboard or processor. Severe overheating can cause melting or leave a charred appearance on both the motherboard and the processor itself. Try removing the motherboard from the tower and disconnect the processor to see if this is the case (steps below). If the overheating was severe, the processor could be permanently damaged. In that case, there’s nothing you can do about it. Replace him and get on with your life. Depending on the damage, the motherboard can also become unusable, so it needs to be repaired afterwards.

Processor failure causes

Like any electronic component, the processor can die for simple reasons. Below are the items that need to be minimized in the system if you want to extend the life of the processor.

Heat. The work processor generates heat, but if the amount of heat exceeds a normal threshold, the work processor may die. It’s the same here: Never underestimate the power of the fans. It is not for nothing that extensive cooling systems are expensive. If possible, place the computer in an air-conditioned room so that the heat can build up slowly.

How to know if the processor fails and how to fix it

Ageing. Some processors can survive all other components, but in most cases you can assume that the old processor will simply give up at any time. If you have an old system (more than 5 years old), the processor may suddenly die, even if properly maintained. The first element of the CPU that usually runs through is the fan. Over time, this moving part simply reaches its natural limit and there is nothing you can do about it. There are millions of transistors in the processor, and if one of them stops working, the processor may fail to perform a certain task. It’s difficult to verify this directly. So once you’ve eliminated all possible causes, all you can do is replace the processor.

Excessive voltage or acceleration. The CPUs are calculated based on their clock frequency. Some CPUs are designed to offer higher clock speeds for better performance, but this is affordable. Ultra-concentration can increase the load on a device and thus shorten the total life of the device during operation. In other words, you trade in processor durability for more computing power, which isn’t bad. However, if you have the means to get a faster processor, we recommend that you do this instead of overclocking.

Voltage jump or unstable voltage. Many processors today are so reliable that they can run continuously for years without failure. However, if you are in an area with frequent thunderstorms or unstable power lines, a power surge can effectively kill the CPU or even the rest of the motherboard’s components. Do not attempt to connect your computer directly to an electrical outlet. If possible, use a surge protector to protect your computer from sudden power surges.

Wrong motherboard. A motherboard is a complex combination of many different components, and sometimes even a bad capacitor can cause another component to fail. Try visually inspecting your motherboard hardware and make sure that the capacitor is not leaking or swelling. If you find it, there’s a good chance the CPU will fail.

Troubleshooting a faultyprocessor

The processor is either… …or not. When properly installed, the processor will continue to run until it crashes, unless a dramatic situation such as a power surge, lightning strike or major damage to the motherboard occurs. However, if it appears that the processor is no longer working, it is best to replace it. period.

Check whether the system is overheating. Before you consider physically removing the processor and testing a new processor, check the system for signs of overheating. Here are some of the specific steps you can try:

  • Make sure the airflow is clean. Sometimes additional cables in the housing can block large ventilation openings.
  • Keep the number of fans under control. Too many fans doesn’t necessarily mean it’s better.
  • If you still have access to the BIOS, make sure that the latest firmware version is installed. The upgrade process depends on the card you are using, so check the documentation that came with your card. Normally you can find out the BIOS version by checking the BIOS string that appears during the boot process. Other motherboards may have a different way to display their firmware version, so please search again on Google or use the manual.
  • Check the fan or radiator. This step only applies if you know how to remove and move the processor. In this case, make sure that the pressure pins are in the correct position and that the heatsink is mounted correctly on the mainboard. At the same time, check that there is no thermal interface material on the underside of the heat sink. If they don’t exist, it could be the cause of the computer overheating. The thermal transition material is often supplied in the form of a heat conductive adhesive.

If nothing happens during startup, i.e. the screen remains blue or black, and you suspect a malfunction in the processor, proceed as follows:

  • Make sure the power LED on your motherboard is on.
  • If the LED is not lit, check if there are any problems with the motherboard or the power supply.
  • If the LED is lit, make sure the CPU fan is running when the system is turned on.
  • If the processor fan is running, a paging test must be performed with another processor. Check that the other devices are working properly.

How can I prevent theprocessor from failing?

Despite its reliability, you want to be sure that your computer’s CPU is fully functional. Since overheating is often the most common cause of processor failure, this is what you can do to prevent it.

Processor heat level control. High quality motherboards provide a tool to control processor temperature and fan speed in your BIOS, so make sure you use it. Again, the implementation of the monitoring tool depends on your existing motherboard, so use the corresponding documentation as a reference. The BIOS monitoring tools are designed so that you can even use the mouse. Temperature measurements are often presented in a simple form so that you can understand them and, if you are lucky, there may be an indication of what is normal and what is not.

If you cannot set a base temperature, you must determine it yourself by noting the temperature at which the processor is inactive. The central unit must then be charged so that the operating temperature can also be taken into account. When running the mainboard monitoring program, set the temperature of the insulation wire to a reasonable value and configure the program to warn you when the temperature is exceeded.

Use good processor coolers. Retail processors offer stock coolers, but if you can afford to buy high quality third-party coolers, go ahead. Aftermarket chillers are generally more efficient than stock chillers, but they can also be noisier, so make your choice based on your needs. If you are looking for good performance, let us take care of after-sales service. If installing a refrigerator, thoroughly clean the surface of the processor before applying the thermal mixture. Also make sure that the heat sink fits properly on the processor.

How to know if the processor fails and how to fix it

Regular cleaning of tower. This is understandable, but once again, the need to minimize the dust in the tower cannot be overemphasized. Dust can clog the ventilation holes, reducing airflow to the processor and other components.

Use of thermally insulated chassis (TAC).  TAC is the original name for a more advanced housing designed to dissipate the extra heat from the internal (exterior) components. TACs can be expensive, but they can be an effective way to minimize the heat inside the box. If you have the necessary resources, we recommend that you use them instead of the standard case.

Location, location. Placing a computer, in whatever form, next to a heat source is a big taboo. A cool, dry place is fine, but an air-conditioned room is preferable. If possible, computers will choose a colder environment than a warmer one every day, so help them get it.
