Your computer shuts down on its own? A one-time problem with the device is not a cause for concern yet, but when the situation repeats itself often and you are not able to work continuously, then you should consider fixing the problem permanently. Nevertheless, do not panic and try to find the cause of such behavior of your computer. Take a look at our list and think about which cause might apply to it.

There are many reasons for unexpected computer shutdown, but most often they come down to the list below.
When a virus, worm, or other malware attacks your computer, expect a whole list of unpleasant consequences. One of them may be just shutting down your computer on its way.
Hackers are able to design viruses to disable the device even in very specific circumstances, e.g. when running a program or at a specific time.
Check if your computer shuts down through software. All you have to do is start your device in safe mode.
If there is no problem in this mode, you are on a good way to see what had happed.
This is one of the most common reasons for your computer to shut down. When the temperature inside the equipment exceeds the norm, the device spontaneously cuts off the power supply so as not to burn the components.Why is your computer overheating?
The first reason is insufficient ventilation. This problem arises when the inside of your computer, especially the fan and heat sink, is covered with dirt dust, hair, animal hair, etc. In this case, the fan does not keep up with the heat dissipation and the computer shuts down. Do not underestimate this problem dust in large quantities perfectly conducts electricity, so it can lead to a short circuit and failure of the device.
When your computer has a ventilation problem, be sure to check the fan itself as well. It could lock (e.g. office paperclip), jam or disconnect. Often, a small intervention will make his work return to normal.
If the components are not dusty, the fan is running, and the computer is still overheating, the cause is usually in incorrect operation of the CPU, RAM or graphics card. In some cases (e.g. RAM), this means that parts need to be replaced with a new one, but sometimes a thorough check of their condition is sufficient. All you need to do is dry the thermal paste between the processor and the heat sink, and the processor will overheat even under light load. After replacing the paste, the problem disappears.
Computer components require specific voltage values during operation. If youre using a power adapter thats too low, your PC will shut down when theres a higher load, such as playing games or working with multiple programs at the same time.
Incorrect connection of the random-access memory or failure of the bracket may cause the problem of sudden computer shutdown.
Double check your computers RAM to see if all brackets are properly connected. It is recommended to carefully check the battens themselves and the gaps to which they are connected: if damage is found, it only confirms the cause of the problem.
If several strips of RAM are connected to the computer, it is recommended to disconnect one point at a time and check the performance of the computer: if one strip is not working, the computer will start up normally and will work.
Typically, this cause of the problem is for the user if changes have been made to the BIOS settings before. Incorrectly set parameters can easily cause the computer to turn on for the first time, but will suddenly shut down due to inability to continue.
In this case, collecting the BIOS settings will help to get out of the situation. As a rule, a similar procedure can be performed if you enter the BIOS and then find and select the parameter Load optimized defaults, Load default fallback settings or Load default configuration settings.
These are the main reasons that could suggest why sudden shutdown of the computer still occurs. If the problem cannot be solved on your own, do not postpone your trip to the service center.
Open the system unit and look at all the capacitors installed there. Their top should be flat.
If the capacitor cap is swollen or dripping on it, it may cause the computer to shut down spontaneously.
Spontaneous shutdown due to component failure occurs relatively rarely. This usually ends with the equipment completely failing to respond to any actions and not being unable to start it.
To cope with this problem, it will be necessary to replace the damaged parts.
This component is responsible for all graphics on the computer, that is, displaying pictures, movies, games on the monitor. And if it doesnt work, your computer might turn off as well.
Very often, users are interested in the question: why the computer turns off during the trò chơi. The reason may be a power supply that cannot withstand the load and a graphics card that does not take graphics. Components in the system unit may also overheat.
If you hear a strange noise while working at your computer, it is better to think about buying a new hard drive.
Bad sectors appear over time, and when the read head hits them, the computer may shut down spontaneously.
Sometimes it is difficult to clearly indicate the reason for the computer shutting down. However, a visit to a specialist involves a considerable expense and a long lead time.
Before you get your device serviced, try these methods. It is very likely that you will cope with the problem without an expensive visit to a specialist.
With a good antivirus, you dont have to be afraid to shut down your computer because of malware. When your machine is protected by a real-time program, you can be sure that no threat will be left out.
When choosing an antivirus program, also make sure that it does not burden your device too much. A bad antivirus will slow down your computer and in extreme cases will turn it off. Take advantage of suggestions from industry leaders like Bitdefender Antivirus
Using professional programs, not only will you not experience the extra load, and you will even notice an increase in performance thanks to the pc optimization feature.
Antivirus organizes the contents of your drive and Windows registry, manages the installed software, and changes many system settings to make your PC run faster and more efficiently.
To cope with contaminants, reach for a container with compressed air. Unplug the computer, open the case, and take it to a well-ventilated area, such as a balcony. Then, remove the residual dust with compressed air. Be careful not to bring the nozzle tip too close to the components this can damage them! Keep at least a few centimeters of distance.
For a máy tính, compressed air is also useful for you. When the fan is running louder than usual, check the outflow and airflow and clean these ducts if necessary.
Some máy tính manufacturers, such as Lenovo, offer a very interesting option to clean the fan from dust. When you launch a special application, the fan spins to high speed for about 3 minutes, so that a large part of the debris is blown out.
Be waithed to suggestions to use a regular vacuum cleaner to clean your computer of dust. Plastic brushes in vacuum cleaners instantly electrify and can cause damage from micro-surges.
When dust cleaning didnt work and your PC is still overheating, youll need to replace the cooling itself.
A weak or well-used fan usually does not do its job. First, replace the fans in the housing. If this doesnt work, you might need to replace the CPU fan or graphics card.
In some cases, when you remove or stop some components of your system, your computer crashes and shuts down itself.
If this is the case for your computer, install the operating system again. The problem should disappear.
The last option to check is the power supply. If all of the above fails, the power supply could be the root cause of the problem. Some of the power adapters do not cost too much and are worth trying because they cost much less than having your máy tính serviced.
The main reasons for the situation in which the computer always turns off immediately after startup are:
Have you checked all of the above and your computer is still shutting down on its own? Be sure to put the equipment into service. When the cause lies deeper, your equipment needs a diagnosis of a good specialist.
Also, go to the site if performing service activities is problematic for you or if you do not have time to do so. When youre not familiar with the hardware enough to unscrew the computer yourself, clean components, and replace parts that may have been damaged, head to a professional for your own peace of mind. When replacing a cooling or graphics card, you need certain skills, without which it is easy to make mistakes or carelessness, which can result in damage to the component.
