If your desktop computer is randomly restarting or shutting down, it could be due to a variety of issues. It could be a problem with the software or driver, not providing enough power to the computer, overheating, malware or a computer virus, or an issue with the power supply, drivers, or hardware. To protect the system from further damage, you can disable the automatic restart option. If you're experiencing random restarts on your Windows 10 or 11 computer, you can try replacing the power cables and the power supply (PSU) to see if the computer keeps restarting.
If your computer mostly restarts while you play, it's possible that the problem is with the GPU (graphics processing unit).

Additionally, if your laptop is overheating more easily than a desktop computer due to its compact size and low cooling power, you can try disabling the automatic restart feature. The easiest way to know if malware or a computer virus are the cause of random closures is to observe the times and conditions that trigger the shutdown. Therefore, when a PC operates at extremely high temperatures (above 60℃), it will shut down to protect its components from further damage.
If you're having trouble with random restarts on your Windows 10 or 11 computer, following these steps can help you identify and fix the issue. Most of the time, laptops overheat more easily than desktop computers due to their compact size and low cooling power. The number of Windows 11 users who experience random restarts is relatively small and the problem is more likely to occur on a computer with an older processor.
