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. 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. Incorrect connection of the random-access memory or failure of the bracket may cause the problem of sudden computer shutdown. 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.
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.
This component is responsible for all graphics on the computer, that is, displaying pictures, movies, games on the monitor. Very often, users are interested in the question: why the computer turns off during the game. 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.
Examine them closely to find out whether any of them is playing up:. The truth is, dusty computers tend to bite the dust first. Dust, dirt, food remnants, hair, and other stuff can overheat your computer by preventing proper air circulation. Besides, trapped debris provides a hospitable environment for germs. If your PC has been overclocked, its components may not be able to meet the increased power demands.
Keep in mind that overclocking your computer is playing with fire: it may cause serious damage to your machine. That is why we recommend you to disable your overclocking utilities — your system should run as fast as it is supposed to.
Otherwise, it may become overheated and a bit neurotic. In order to identify the problematic device, try utilizing Device Manager. This Windows utility generates error codes and helps you troubleshoot device issues.
If you have refurbished your PC recently, remove the newly added hardware and check whether your computer is OK. The point is, your new hardware may lead to incompatibility problems and bring about spontaneous shutdowns. Already have a list of suspects? Good for you! Try removing your hardware items one by one — this might help you troubleshoot the issue. Not a hardware expert?
You have nothing to be ashamed of: most PC users lack hardware expertise. Search for a trustworthy service center and have your computer diagnosed by IT professionals.
You can troubleshoot your drivers manually one by one. You might need to completely uninstall your drivers first and then reinstall them. While you can replace the power supply yourself, don't try to open the power supply. Even though it's unplugged or failing it can still carry a deadly charge.
Computers come with heat sinks and fans to keep the Central Processing Unit CPU cool but if the CPU overheats the computer will shut down so that it isn't damaged any further. Adding thermal paste between the CPU and its heat sink can help prevent overheating as can working cooling systems like fans or water cooling.
Dust and pet hair can get sucked into the computer case and clog up air flow as well, causing the CPU to overheat. Keep the insides of the computer clean using compressed air to blow out any foreign objects. If the power supply fan is not working correctly or at all, and the power supply is very hot to the touch, replace the power supply. An overheating power supply, due to a malfunctioning fan, can cause a computer to shut down unexpectedly.
Continuing to use the faulty power supply can result in damage to the computer and should be replaced immediately. Software utilities, such as SpeedFan , can also be used to help monitor fans in your computer.
Before attempting to remove any hardware, rule out hardware conflicts by checking Device Manager for errors, see: How to Identify problems in the Windows Device Manager. Any failing hardware component in your computer could cause your computer to unexpectedly turn off without warning. If you have recently added any new hardware, remove it from the computer to make sure it's not causing the problem. If you have not recently installed any new hardware into the computer, the next best solution is to systematically remove non-essential hardware.
For example, remove your modem, network card, sound card, and any other expansion cards that are not needed for your computer to operate. Running the computer without these cards may help diagnose your issue.
Make sure any surge protector or UPS uninterruptible power supply is not causing your problem by connecting the computer directly to the power outlet on the wall. Also, if you have a UPS that connects a USB cable to the computer to manage power saving features, make sure it is disconnected. If this resolves your problem, you may have a defective surge protector or UPS. Make sure there are not too many devices connected to your UPS and that it has the latest software updates.
