Computer turning off under load

Whether it is gaming, streaming movies, or working, a computer is your go-to device. However, many people like to multitask; they want to operate multiple applications at once for convenience. It may also be that they use very demanding software that stresses the components of the computer. This may include playing video games with some other applications running in the background, playing video games on the maximum settings, or using demanding software such as 3d modeling/video editing. As a result of this, the computer turns off unexpectedly. Today I will solve the common problem of computers turning off unexpectedly under stressful tasks.

Why does my computer turn off unexpectedly?

Before I start giving out solutions, you need to know why the computer turns off unexpectedly. When you use demanding software, the computer components may seize and therefore turn off; in such scenarios, your screen will turn black instantly. Why do the Components seize? The Components seize for many possible reasons. It could be that they are not getting enough cooling; this causes them to overheat and die. It could also be that the components draw more power than provided. It could be caused by malware in your system. It can also occur due to issues in the operating system, e.g., Windows.


Now I will propose solutions to fix your computer turning off under stressful tasks below. Make sure you try all of the different solutions down below. I recommend that the first thing you do is that you check whether your computer is plugged in correctly as a loose plug is the most common root of this problem.

1-Check Your Components’ Temperature

Heavy load on a GPU (graphics card) or CPU (Processor) causes them to heat up. Don’t be alarmed, as this is entirely normal. The average temperature for these parts under heavy load is 70-90 degrees Celsius. Note that this may vary between different components. However, excessive heat may not be normal and cause problems. Extreme heat not only shortens the computer’s lifespan but also has a chance of rendering the computer useless as the parts can burn and die.

Ways to check the temperature of your computer:
  • Open your CPU/GPU’s software
  • If you can’t find or don’t have the software, then download MSI afterburner.
  • If you have a rough estimate of how hot it usually gets, place your hand over the exhaust and denote if it feels hotter than usual.
The solutions to reducing high temperature:
  • Put your computer near a fan/Cooler place.
  • If it is placed on a carpet, then move it (carpets block airflow).
  • Check if the rear, front, or top fans of the computer are blocked and if so, then remove the blockage.
  • Next, get the thermal paste replaced on your major components.
  • Finally, clean the computer from the inside (with a fan) so that unwanted dust may be removed.

2-Check the power consumption

Nine times out of 10, people forget to upgrade their power supply when upgrading to a better system. Or they just buy the wrong power supply for their computer. When the Components draw more power than they are provided with, they shut off unexpectedly. Components draw more power the more workload they are in, which may be why the computer doesn’t shut off during routine tasks.

To fix power consumption, you can:
  • Check the power consumption of your other parts, and then buy a PSU (power supply) accordingly.
  • Upgrade your current PSU.
  • Undervolt your components if you do not want to upgrade the PSU yet.
  • Try to connect the power supply to another electrical switch in the house (in case of a faulty switch).

3-Install an anti-virus on your computer

malicious software such as viruses and malware enter the computer and do all kinds of harm to it. This could be one such case. To try to fix this problem, you should try to eradicate such malware.

this can be done by:

  • Scan your computer via windows anti-virus.
  • Deleting a file that you suspect to be corrupt or containing a virus.
  • Stopping the download of illegal software or apps from an unsecured internet page.

4-Reinstalling Windows

This may be used as a last resort if, in any case, the solutions mentioned above don’t work. For example, it can be that some of the files in your operating system have gotten corrupted, leading to all sorts of issues. You can reinstall the software or factory reset your computer to fix such files.

“To check if the computer turns off in stress again, try a stress test; they can be downloaded online (verify their safety before using). This will also help in verifying solutions 1 and 2.”
