Windows PC Shuts Down Randomly | 8 Things to Check & Fix the Issue

Have you ever seen when a Windows PC shuts down Randomly? Issues like a faulty PC battery, a loose power cable, overheating, misconfigured power setup, outdated drivers, or even faulty PC components could be the cause.

If you’re stressed out by this problem, you should try these solutions as stated in this article. Find out how to use your PC to perform preliminary checks, check issues with your battery, make sure your device is not overheated, and other applicable solutions.

Perform Some Preliminary Checks with a PC

Unlike laptops, which gain power from their battery, a PC relies on a steady connection to an external power supply to remain active and on.

If the power cable is not connected tightly to the PC or the socket, even a slight push can disrupt the flow of current, which can lead to a shutdown.

Moreover, you should inspect the power cable for any signs of damage, and insert the power cable into a different socket to eliminate potential socket-related issues.

If you make use of a UPS to customize power outages, make sure that it’s not faulty and supplies stable power. Moreover, if you’re overclocking your CPU, turn off overclocking, because it could result in similar issues.

Check for Issues with your PC’s Battery

When you’re experiencing an issue with a laptop while using it on battery power, make sure a faulty battery is not causing it.

To check this, pull out the battery from your PC, plug the official charger with the adapter into an eclectic outlet, and run the PC directly on the power supply.

If the same problem does not occur while using a direct power supply, the battery will surely be faulty. On the other hand, if you face the same issue while the PC is powered directly, then the battery is not to blame. Try out other solutions.

Ensure your Device is not Overheated

When your Windows PC shuts down randomly only when it’s overheated, heat is likely to be the issue. Such things happen to computers because computers have a protection mechanism that kicks in to block off damage to the hardware components.

To confirm that the issue is due to Overheating, run fewer tasks on your PC that do not cause overheating.

If your PC is fine running tasks that do not use many resources but crashes when running intensive applications, heat could be the issue. You should check your Task Manager to see which program is using up the system resources.

If eventually, overheating becomes the cause, there are easy steps to keep your PC’s temperature at a safe level. By doing this, you can prevent the recurrence of the same problem.

Meanwhile, when using a desktop ensure all of your fans are running, and take some time to thoroughly clean your PC, and create good conditioning for it.

Disable Fast Startup

Fast Startup is an important feature that speeds up devices’ boot speed. On the other hand, it can also result in unforeseen problems, which include hindering system updates, preventing your access to BIOS or UEFI settings, and at times causing system shutdowns.

You should turn it off or disable it temporarily to rule out Fast Startup as the primary suspect when your Windows PC shuts down randomly.

To do this, type Control Panel into the Windows Search Bar, and open it. Go to Hardware and Sound > Power Options, and choose “What the Power Button Does” on the left side.

After that, you should uncheck the box beside “Turn on Fast Startup“, and click “Save Changes“. If disabling the feature does not resolve the issue, re-enable it and try the other troubleshooting steps.

Check the Power Supply Unit (PSU).

When your PSU is not powerful enough to meet the demands of your system components, it can also cause random shutdowns. To check this out, calculate the wattage draw of your computer based on the specs of installed components.

If the needed wattage is lower than your PSU’s wattage, you’re fine. But, if it eventually exceeds your PSU’s capacity, you need to upgrade your PSU.

If your PSU can supply the power needed, test it to see if it has no hardware problems. You can do this by carrying out a jumper test. If the PSU is not working as it should be, then you have to replace it.

Ensure the RAM and Storage Drive Isn’t Faulty

Like an underpowered or broken PSU, faulty RAM can result in random shutdowns. To check if your RAM is working perfectly, you have two choices to make:

You can use the built-in Windows Memory Diagnostics tool or try an easier tool that’s called the MemTest86, it helps you find problems with your RAM easily.

Also, if the storage drive that houses your OS is faulty, it causes a similar problem. Therefore, run a S.M.A.R.T. test to check its health and make sure it’s working perfectly as it should.

There is no practical way to repair your RAM or a storage drive, so if any of them are faulty, then you have to replace them.

Update Your Drivers

When your drivers are faulty, it can also cause your system to shut down randomly. To rule out this is possible, type Device Manager in Windows Search and open Device Manager.

If you see a warning sign or exclamation mark next to a driver, it shows that it’s outdated or corrupted. So, one needs to update it or reinstall it from scratch.

To do that, you need to download the drivers from the manufacturer’s website. If the driver comes in the form of an executable file, you just need to run it to install. Unless manually update the driver via Device Manager.

Right-click on the driver and choose Update Driver. Then, you should click “Browse MY Computer for Drivers” and select the downloaded driver file from the Downloads folder.

Ensure that you update drivers for the GPU, battery, disk drives, processor, USB controllers, and other software components, even though you don’t find any warning signs close to them.

Also, you may be able to find an error message in Event Viewer that will relate to which driver is the problem.

Change Advanced Battery Settings

If the above solutions have not yet resolved the issue, recheck your battery settings, especially the low battery action settings, and make sure they are perfectly configured.

To carry out this task, type Control Panel in the Windows Search bar, and open it. Navigate to Hardware and Sound > Power Options, and click “Change Plan Settings” for the power in use.

Navigate to Battery > Low Battery Action and choose “Do Nothing” if “Shutdown” or “Hibernate” is currently the one selected there. Finally, click on “Apply” and hit OK.

If your PC was experiencing random shutdowns due to specific causes discussed above, you should be able to address the issue now. If the problem continues after trying all the suggested fixes, you should seek assistance from a professional to resolve the issue for you.
