Solution 1. Check the Computer for Overheating

The processors used in computers might get heated up when used extensively. Generally, the computers are programmed to shut down after sensing heat up to a specific temperature. This is a precaution the developers take while manufacturing to reduce or protect the software and hardware components from damage.

Majorly overheating is the main reason why most PCs shut down abruptly. Many reasons can cause overheating problems. If you use your computer for long hours at work, like editing videos or playing high-graphics video games, you are likely overusing the processor. In most cases, laptops are more prone to overheating problems when compared to desktops.

Along with these, several other reasons why your PC is overheating are

  • Dust, dirt, hair, and debris prevent the proper airflow inside the system.
  • Cooling fan problems.
  • PC overuse or carelessness
  • Dried out thermal paste between the CPU and heat sink.

Dust and Dirt

People often do not keep their PCs clean, a lot of time you can see dust, dirt, hair follicles, and food remains on the computers. These particles clog the gaps on the computer by preventing the air circulations inside the laptops/desktops. Along with this, trapped debris is prone to attract germs causing major issues for the airflow around the device.

You are responsible for keeping your devices clean and tidy to avoid such problems. Remove the dust and dirt particles on your PCs regularly, and avoid eating around the computer.

A faulty cooling fan or a power supply unit (PSU) fan

It would be best if you had proper cooling fans, case fans, or processor fans to use the PCs extensively, and they protect the device from overheating. Any malfunction of the cooling fans can only increase the problems of overheating.

If your fans keep making noise, they must be broken, and if they have dirt or dust on them, they will stop working correctly. If you observe any such issues, replace or clean them.

PC overuse or carelessness

You must be keeping your PC cool. If you overuse your computer or use the device in unfavorable conditions, the computer shutdowns itself to reduce the damage to the software and hardware.

In both situations, you either challenge the system to satisfy your increased demands or push it through undesirable conditions, resulting in overheating issues.

Here are some tips to avoid these instances:

  • Work in a properly ventilated area.
  • Avoid direct sunlight on your PC.
  • Do not keep your computer in hot/humid places and zones.
  • If you are using a laptop, use a cooling pad.
  • Elevate your laptop if the cooling fans are under the device body.

Replace the Thermal Paste

If the thermal paste between the heat sink and the CPU is dried, it may cause heating issues. Remove the dried-up paste and replace it with a new coat.

Solution 2. Rectify the Hardware Issues

Faulty hardware can make your PC shut down abruptly. You cannot view or know the root cause of the problem since it is a hardware issue. For such cases, you can use the Device Manager to find the problem and generate error codes to troubleshoot the device.

On the Windows 10 Computer, You can access the Device Manager using the following steps:

Start -> Control Panel -> Performance and Maintenance -> System -> Hardware tab -> Device Manager

You can also use

Win + X -> Device Manager

You can check for faulty or outdated drivers in the Device Manager section and update them. Use the steps mentioned in solution 2 to open the device manager and follow the below steps to check and update the faulty ones.
