If you’re experiencing the problem that your computer shuttings down while playing games, you’ve come to the right place. Don’t worry, you’re not alone. The problem can be caused by different issues. So there’re several methods to fix it. All methods apply to Windows 10, 7, 8.1 & 8.
Without further ado, let’s straight to the point:

What’re the causes and how to fix it?

There are many possible reasons which will cause the shutting down problem. Here we list 5 common reasons and each of them has a corresponding solution. Just try the methods one by one until you have the problem solved.

Fix 1: Deal with the overheat

If you hear unusual fan sounds, increasing or sustaining a high temperature on idle state, the problem is most likely caused by overheating. It’s becasue computer has a self-protection mechanism. When the temperature reaches a certain level, your computer will automatically shut down.
There’re many reasons for the overheating, if you want to have a comprehensive understanding, you can read this post.

The fix for this problem is simple. Clean the dust, check your cooling system and your thermal paste. These steps will lower the temperature and prevent your computer from overheating again.

Note: If you’re using a laptop, we don’t suggest opening the computer as mentioned above. You can use a cool pad or lift it up to leave enough space between the desktop and your laptop.

Fix 2: Change PSU

PSU refer to the Power Supply Unit. The component supplies power to the computer. Most of the time when a computer SHUTS DOWN unexpectedly when playing games, it’s the PSU.
We normally will ignore the power supply unit, but it’s an important component that provides stable, continuous current for all computer equipment such as CPUs, memory and hard drives. When PSU failed to provide a stable power or it’s insufficient, your computer cannot work normally and even cause damage to the hardware.

How to check your PSU

The easiest way is to try a different PSU on your computer and see the result.
Or you can test it with a multimeter/power supply tester.

When you’re sure it was indeed the PSU, changed it and everything works well again.

Fix 3: Run a malware check

Running a malware check is a simple but necessary method for your computer. If your computer is affected by malware, it is possible your computer would shut down accidentally when you play games. Make sure you have the latest version of antivirus software. Perform a malware check to avoid malware affecting your computer regular processes.

If your computer is clean, move to the next method.

Fix 4: Update your drivers

It is important to keep your devices’ drivers updated. Windows 10 doesn’t always give you the latest version, but with outdated or wrong drivers, you may encounter computer shutting down unexpectedly issue. So it’s really important to keep your drivers updating to get better user experience.

There are two ways you can update your driver: manually and automatically.

Option 1 – Manually– You’ll need some computer skills and patience to update your drivers this way, because you need to find exactly the right the driver online, download it and install it step by step.

OR

Option 2 – Automatically (Recommended)– This is the quickest and easiest option. It’s all done with just a couple of mouse clicks – easy even if you’re a computer newbie.

Option 1 – Download and install the driver manually 

You can download graphics drivers the manufacturer official website. Search for the model you have and find the correct driver that suits your specific operating system. Then download the driver manually.

Fix 5: Other hardware issues

Except for PSU, any failed hardware component on your computer can cause your computer to shut down unexpectedly without warning. If you have added new hardware recently, you need to remove it from your computer and check whether it is the cause of the problem.

If you haven’t added any new hardware on your computer recently, you’d better remove unnecessary hardware one by one to diagnose the problem. For example, remove your modem, network card, sound card, and any other expansion cards one by one. Then running your computer without these cards to diagnose the problem.
