You have probably witnessed your computer shutting down for no reason. This behavior should not cause worry if it is a one-time thing. But if the process repeats itself often, it is time to fix the problem once and for all. Your computer shutting down can be utterly frustrating as it sometimes disrupts your work process. However, this does not call for panic and thinking your computer is useless.

Possible causes for your computer to shut down

Before concluding your computer has shut down, you should first know how to check a perfectly running computer. Some of the things you should check include; your CPU producing a silent humming sound (this is due to the fan), LED lights near the power button on the CPU, LED lights near the LAN port, some warmth (not heat) from the CPU, LED light on the monitor near the power button, and many more. When all these conditions check, then your computer is alright. If they do not match, it’s time to get to work. Most of the causes for computer shutting may be software or hardware-based.

In the list below, we will find out some of the causes of computer shutdown.

Power saving mode

Power saving mode on your computer is a feature that shuts down your computer monitor temporarily to reduce the power costs actively. Power saving mode is mainly activated when the computer is not in use for a short time. Power saving should not be a wholly cause for concern. But if it concerns you, you can always turn off power saving mode at your computer settings.


Overheating is one of the most common causes of a computer shutting down. Nowadays, most computers are programmed to shut down after heating up to a specific temperature. The most common reason for overheating is excessive dust accumulation. Keep your computer dust free as often as possible, which will keep your computer running smoothly.

Power loss

Computers use electricity to run. A power loss will lead to your device shutting down, which should not be a significant cause for concern.

Driver issues

Another probable reason for your computer shut down is faulty or out-of-date drivers. It is essential always to update your drivers regularly. To update manually, click start and select device manager. Expand the drivers one by one, right-clicking each and selecting update driver. However, this could be tedious. Some software (for example, driver support ) automatically updates and keeps your device drivers routinely updated.

Malware infection

Some viruses, worms, and other attacks precisely do what they were programmed to do. Some of these viruses are created to shut down your computer. Cleaning out malware on your computer might require professional assistance. Installing a good antivirus software that will confidently defend your computer from malware is also recommended.

Battery failure

If your laptop becomes unpredictable and keeps shutting down, maybe it’s time you check your battery. Many batteries run into problems sooner or later. You should consider replacing your battery. Make sure the battery rhymes with your laptop

BIOS failure

BIOS (Basic Input/output system) is a built-in software responsible for booting up your system. Incorrectly engaging the incorrect BIOS parameters can easily cause the computer to shut down. Initializing the BIOS settings will help you solve this problem.


The above mentioned are just some of the common causes of computer shutdown. The best part is that most of these problems are easily remedied.
