computer randomly turns off

Most of us face the issue that our computer turns off for no apparent reason. How aggravating! Random turn-offs might sabotage a video game or erase unsaved work. Many things can contribute to this problem. First of all, pay attention when the PC turns off. Does it seem completely random, or does it only happen when you try to run a specific application? Looking for a pattern when the PC turns off will help you narrow it down to possible causes. There is more to discuss on why compiter randomly turns off, let’s start the article. 

Why my computer randomly turns off?

A computer can randomly turn off on its own for a variety of reasons; including hardware and software issues. The most common reasons for a computer shutting down without an error screen can be found in this guideline with their solutions.

Check your power supply

Power supply issues are one of the most common and straightforward computer issues to resolve. These problems can cause your computer to shut down. It is a safe bet that you probably have a plug-in the wall outlet hidden behind a couch, and when someone comes by and sits on the sofa, they yank the cord out of the wall. It is important to ensure that all the cables are plugged in securely from the wall to the power strip to the power supply. Don’t stop there. Turn the PC off and remove the desktop’s case door. Take a look around and inspect that all the cables are snugly inserted, e.g., both data and power connectors. 

Prevent it from overheating

After the power supply, the temperature of the computer should be checked. Computers are sensitive to specific temperature ranges and should not be exposed to temperatures higher than 60 degrees Celsius. Internal dust accumulation can cause heating issues over time. The first step in preventing computer overheating is to keep the computer’s interior clean. Overheating a computer can cause it to fail and cost you a lot of money.

Maintaining a dust-free computer is definitely worth the effort and can save you a lot of money in the long term. Cleaning fans on a regular basis ensures that they perform properly and are in good functioning order, which will aid in computer cooling. Therefore, turn off your computer and thoroughly clean the fan with a canned duster or cleaner to keep it from overheating. It’s also not good if you have gadgets nearby that are blowing hot air into the computer’s intakes. The airflow around the fans should ideally be consistent and enough, with enough area for the computer to breathe.

Check your Graphic cards

If your computer shuts down while you’re playing video games, the issue may be with your graphics card. Check the power wires and make sure the graphics card is properly seated in the PCI express slot on the motherboard. If the card is receiving power and the card is turning, the graphics card is most likely in good working order, and the issue is most likely with the software.

In order for your computer to play the game, a graphics card must communicate with your operating software through a driver. It’s conceivable that your graphics card is using an out-of-date driver, which is causing system instability while you’re playing games. Another option is that you’re using a beta driver that isn’t yet reliable enough for consumers to utilize. So, try updating your graphics cards’ driver to the most recent non-beta version.

Detect the Hardware issues

If your hardware has failed, it may automatically cause Windows to shut down suddenly or without any warning. Remove any new hardware you’ve recently introduced to the computer to make sure it’s not the source of the problem. When your computer makes a lot of noise, it’s usually due to a hardware problem or a noisy fan. Hard drives generate a lot of noise right before they fail, so you should back up your data just in case. If you haven’t added any new hardware to your computer recently, the next best option is to remove non-essential hardware one by one.

Remove your modem, network card, sound card, and any other expansion cards that aren’t required for the operation of your computer. Running the computer without these cards might help you figure out what’s wrong. You can change each part to see if it’s at fault if you have extras or know someone who has a comparable arrangement. Otherwise, you’ll need to take your computer to a computer repair shop.

Turn off fast startup

Fast startup is a designed feature of Windows 10. It prevents the computer from shutting down normally and may cause device compatibility difficulties. Shutting down your computer with Fast Startup activated may appear to be totally shutting it down; but this is not exactly true since it enters a stage halfway between hibernation and shutdown. It is incompatible with a large number of systems, and it is more likely to cause problems than it is to solve them. Because Fast Startup is a Windows function, leaving it enabled should not harm your computer, but it could be the source of this issue.

Update Your BIOS

If your computer keeps shutting down unexpectedly, it’s time to update your BIOS. Please proceed this step with caution; else, your computer may be permanently destroyed. If you are unsure of your abilities, we advise you to get professional help.

Scan Computer virus

The virus in your computer may be one of the big causes of the sudden turning off the computer on its own. After the detection of a virus in your computer, scan your computer using the main security system. You can also install some antivirus software like Kaspersky antivirus or G-Data. Make sure to install the latest version of the antivirus software. Confirm the results of your anti-malware scan by running a full scan with another malware detection program.
