Top Reasons for Computer Keeps Shutting down while Playing Games

Computer Overheating

While you are playing a game on your computer, the game uses the CPU and GPU that are installed on your device. Playing gaming will put more stress on your device compared with ordinary desktop apps. Both CPU and GPU are small elements that are packed in a small chassis. But the airflow of heat only has a small window to vent out. If the heat is not evacuated in time, the computer will overheat. The result may be that your computer automatically shuts down or it might damage certain components inside.

Virus Attack

If your computer is attacked by malware or viruses, the computer keeps turning off while playing games can easily occur. You have no idea how a virus can damage your computer, one way or another. Interfering with your normal use of your computer like computer shutting down randomly without warning is one way. If your computer keeps shutting down even if you are not playing a game, you should consider if your device is virus infected.

PSU Problems

The full name of PSU is Power Supply Unit. This unit supplies power to the computer. The power supply is another factor you should consider when your PC keeps shutting off while playing games. But it is an easily overlooked issue. Now, let’s face the problem. When PSU fails to provide stable power or its power supply is not enough, your computer will shut down without warning and it might even damage the hardware on your PC.

Besides, if you install a new latest graphics card but still use an older PSU, the PSU should be outdated. You need to have a check and replace it if needed.

If graphics drivers are corrupted or outdated, your computer is prone to problems like keeps turning off when playing games. Windows OS doesn’t keep your drivers up-to-date all the time. You should manually check for updates. If necessary, you should install the latest version of the graphics drivers to make everything work normally.

Hardware Issues

If your PC shuts off while playing games after you install new hardware like a Bluetooth adapter, Wi-Fi card, or a new GPU, the issue should be caused by that newly-installed hardware. Usually, it is caused by an incompatible driver.

System Issues

If the issue happens after you update your system, the new Windows version could be the cause. The games on your PC may not be compatible with the new system. You can go back to the previous version and check if the issue is solved. However, if you haven’t updated your system before this problem occurred, you might need to perform a Windows update to have a try. The update might contain a fix for that issue.
