PC Randomly Turns Off – How to Fix Windows Computer Shutting Down

We got a call from a client last week – Hey team, my desktop randomly turns off! – Please help!

Your computer shutting down randomly can be a frustrating experience. It can cause data loss and make it difficult to get your work done.

If your computer is shutting down randomly, it could be caused by a variety of issues. But don’t worry – there are some things you can do to fix the problem.

It can be immensely frustrating when your computer keeps shutting off without warning. Restarting your computer only to have it turn off a few minutes later is one of the most common computer problems people encounter. It could be anything from a faulty power supply, faulty or outdated drivers or corrupt files on your hard drive.

There are a few reasons why your computer might be shutting down randomly.

It could be due to a software issue, a hardware issue, or even something as simple as a loose power cable.

In this article, we will show you how to fix the problem so that your computer does not turn off without warning.

1. What to do when your computer turns off randomly

Power supply

First, check to see if the issue is with the power supply. If the power light on your computer is off or flashing, it could be a sign that the power supply is not working properly. If this is the case, you’ll need to replace the power supply.

Computer overheating

If the power supply seems to be working properly, the next step is to check the temperature of your computer. If it’s overheating, it may turn off randomly to prevent damage. This can happen if the fan is not working properly or if there is too much dust in the case. To fix this, you’ll need to clean the fan and make sure there is good airflow inside the case. Make sure there’s plenty of airflow around your computer, and consider investing in a cooling pad or fan if needed.

Software issue

If the power supply and temperature seem to be fine, the next step is to check for a software issue. One common reason for random shutdowns is a program or driver that is not compatible with your computer. If you recently installed a new program or driver, try removing it to see if the problem goes away. You can also try updating your drivers to see if that fixes the issue.

If you’re not sure what is causing the problem, you can try using a system restore point to go back to a time when your computer was working properly.

Defective hardware

If neither of these solutions works, it’s likely that there is a defective piece of hardware. This could be the motherboard, CPU, RAM, or power supply. You’ll need to test each component to narrow down which one is causing the problem.

2. How to prevent your computer from shutting down randomly

There are a few things you can do to prevent your computer from shutting down randomly.

Update your BIOS and drivers

First, make sure you have the latest BIOS and drivers installed – from the device manager. These updates can fix bugs that could cause your computer to shut down.

Monitor your CPU temperature

Another thing you can do is monitor your CPU temperature. If it gets too hot, it can cause your computer to shut down. You can use a program like SpeedFan to monitor your CPU temperature.

Check for malware

If the temperature doesn’t seem to be an issue, the next step is to check for malware or viruses. Run a scan with your anti-virus software and remove any malicious files that are found. Finally, if you’re still having problems, there may be an issue with your computer’s hardware. In this case, you’ll need to take it to a professional for repairs.

Finally, you should scan your computer for malware. Malware can cause all sorts of problems, including making your computer shut down randomly. You can use a program like Malwarebytes to scan for and remove malware.

3. How to fix a Windows computer that is shutting down randomly

One of the most important steps you can take to ensure your computer is running smoothly is to keep your drivers up to date. Outdated drivers can cause several problems, including crashes, glitches, and reduced performance. Even if your computer seems to be running fine, it’s important to regularly check for updates. Manufacturers release new driver versions regularly, and these updates can often improve performance, stability, and compatibility. The best way to stay on top of updates is to use a driver update tool. These tools scan your system for outdated drivers and provide an easy way to download and install the latest versions. Many driver update tools also include other features, such as backup and restore capabilities, making them a valuable addition to any PC toolkit. If you’re looking for a reliable driver update tool, we recommend Driver Booster. This tool is free to download and use, and it’s compatible with all major versions of Windows. Another bonus is that Driver Booster can also update your GPU drivers, which are often overlooked but are just as important as other drivers. So if you want to keep your system in tip-top shape, make sure you keep your drivers up to date.

Many people are unaware of the Fast Startup feature in Windows and how it can impact their computer’s performance. Fast Startup is a Microsoft feature that helps your computer start up faster after being turned off. However, it can also cause your computer to take longer to boot up if you have a lot of programs installed. In addition, Fast Startup can cause your computer to use more power, which can shorten its battery life. If you’re not using the Fast Startup feature, it’s recommended that you turn it off. You can do this by going to the Control Panel and selecting “Power Options.” Then, click on “Choose what the power button does” and uncheck the “Turn on fast startup” box.
