There are many reasons why a computer can stop working properly and freeze. Some of them impossible to solve but fortunately less common, and others more common and easy to solve. In this last group, defective RAM modules, overheating due to dirt, viruses, and insufficient power supply can leave our PC out of combat.
You have all ever suffered the symptoms that something bad is about to happen with your computer. First, small “pulls” are observed, then something stops responding so that finally the application with which you are working freezes, state that ensure those who have suffered it, usually occurs at the least opportune moment, leaving without the possibility of continuing to work , and in the worst case, that part of what you are doing with the PC is lost forever.
The scene ends after a few minutes of agony, when the dreaded BSOD, the blue screen of death, finally appears on the scene, indicating that our PC has just suffered a rather important hang. Now it only remains to restart it and hopes that the problem has disappeared without too many consequences.
In this article, you will find the solutions to the most common damages that a computer can suffer, and that produce most of the crashes.
The 5 most common problems for a PC to crash and how to solve them
As we mentioned, there are many causes for a PC to crash, and now it becomes vital to know how and why they occur to be prepared and to avoid or face them.
1. Faulty RAM
A faulty RAM module is one of the most important causes of problems and the main actor in the production of blue screens at system startup. Fortunately, analyzing and detecting problems in RAM modules is simple, and in the case of encountering problems, they are easy to replace.
To check the proper functioning of a RAM module nothing better than an application called Memtest86 +, which will analyze the memory banks for problems. In case you find errors, then it will be necessary to determine which module is producing them.
To do this, you must remove the lid of the PC cabinet and remove the RAM modules, leaving only one of them, the one located in slot 1, in case they are more than one. Next, you run Memtest86 +, and if it does not indicate an error, it will mean that this RAM module does not see any problems. If we have more than one module, we repeat the procedure as many times as we have modules.
The performance and stability of the RAM are of vital importance so that a computer does not freeze. If the memory modules are in poor condition, we are likely to have many problems.
2. Power supply with insufficient capacity
Thanks to the fact that we can now have high-performance PC components at a reasonable price, it is quite likely that our PCs have very powerful CPUs, video or soundboards installed. It is also possible that we have made some touch of “Overclocking” to the processor since they are prepared for it.
But unfortunately, all that power has a price, and it is the high amount of energy consumed by all those components, which can make the system unstable and freeze a computer many times a day if we do not have a powerful enough power supply as to power the entire PC efficiently.
To know exactly the total power consumption of the PC, you will first have to add the consumption of each of the elements that compose it. This is not easy since we will have to resort to manuals or manufacturers’ websites. But once this data is recovered, we can compare it with the power that can deliver the power supply of our computer.
If we conclude that the power supply is not able to supply the necessary power, then it is time to replace it with a higher capacity, since it can cause a PC to freeze and leave us without the possibility of Finish what we were doing.
Generally, if we have a PC with good performance components, but without exaggeration, a power supply with at least 600 Watts will be sufficient. But if we have non-standard configurations such as two video boards connected by SLI or CrossFire, in addition to many other boards, this power will not be enough, having to acquire one of at least 800 Watts.
Inside a PC, whether desktop or portable, large amounts of heat generated by the components housed inside the device are generated. Even in these small tablets with Android, this problem happens.
If the heat inside the PC does not dissipate properly, it can cause instability and cause accidents such as the PC freezing. Although some modern equipment has a series of sensors inside that allow it to measure the temperature and turn off the equipment in case the allowed limit is exceeded, the truth is that before this happens you should check a series of aspects related to fans and ventilation openings.
First of all, it is necessary to ensure that all the fans available to the PC are functioning properly. If any of them do not work, or do it improperly, it is best to replace it.
It will also be necessary to check the openings and vents to verify that they are not being obstructed by elements that do not allow you to successfully ventilate the equipment.
To get an idea of the operating temperature of some of the PC components, you can download and install a small free program called “Open Hardware Monitor”, available on this link.
With this tool, you can monitor the temperature of the processor and other components of the PC, in addition to obtaining other important data about the operation of the equipment.
Another problem related to temperature occurs when you change a processor since a bad application of the thermal paste between the CPU and it heatsink can cause it to overheat and freeze the computer.
To repair it, or take it into account for future updates, you just have to remove the heat sink located on the processor and clean the two surfaces, the heatsink, and the processor, with a cotton pad, moistened with alcohol and place a single drop of thermal paste. The latter should be taken into account since if too much or too little is applied, the heat dissipation is not adequate.
4. The usual suspects: Virus and malware
Both viruses and malware are usually one of the most common causes of a computer to freeze and produce damage and blue screens. Fortunately, getting rid of these nefarious tenants is now quite simple. you just have to use a good antivirus that is up to date and perform a thorough analysis of our computer.
If the virus or malware has deactivated the antivirus, which is possible, you must restart the PC in safe mode by pressing the F8 key during the boot of the same, before the Windows start screen appears.
This will ensure that Windows does not load drivers or software that are not essential for its operation. When Windows has started in safe mode, then you do a full scan with our favorite antivirus.
5. Hardware conflicts
That a computer freezes and the blue screens are shown can also be the result of conflicts between the hardware components of our PC. One of the most common problems of hardware conflicts arises when two devices try to use the same IRQ. Fortunately, in many of these cases, it is easy to find a solution.
To do this, you open the Device Manager, where you will find the list of all the devices installed on the PC. In the case that you see that a yellow triangle is shown on any of them, then it means that this component has a problem, which can lead to complications even to the hardware that depends on it, which will inevitably lead to the computer freezing.
Generally, updating or reinstalling the component driver and a system reboot ends the problem. If the problem persists, and the component that fails is of the removable type as a storage unit, you can try to solve the problem by uninstalling it and reinstalling it.
The best you can do in the event of a problem is to store as much information as possible about it, which will allow us to make a more complete, accurate and quick diagnosis. For this, you can write down the data that appears on the blue screen or use an application like BlueScreenView to help in the diagnosis, which you can download for free by clicking on this link.
It is also essential to be aware of any situation that is not usual in the behavior of the computer that leads to it freezing because if you ignore them you will only make the situation worse and make it more difficult to face a solution later.
