    If your computer is overheating and shutting down, here are some steps you can take to address the issue:

    1. Check Ventilation: Ensure that your computer has proper airflow. Make sure that vents are not blocked and that there is enough space around the computer for air to circulate.
    2. Clean Dust Accumulation: Dust can accumulate inside the computer, obstructing airflow and causing overheating. Open the case (if it's a desktop) and clean out any dust from fans, heatsinks, and air passages.
    3. Inspect Fans: Verify that all fans are functioning correctly. If a fan is not working, it may need to be replaced.
    4. Thermal Paste: If you are comfortable doing so, consider reapplying thermal paste on the CPU and GPU. Over time, thermal paste can dry out and lose its effectiveness.
    5. Monitor Temperature: Use software tools to monitor the temperature of your CPU and GPU. This can help you determine if overheating is indeed the issue.
    6. Check Power Supply: Ensure that your power supply is adequate for your system's needs. An underpowered or failing power supply can cause instability and overheating.
    7. Reduce Load: Try to reduce the load on your computer by closing unnecessary applications or reducing graphic settings in games.
    8. Environment: Ensure that the room where your computer is located is well-ventilated and not excessively hot.
    9. Consider a Cooling Solution: If overheating persists, you might want to invest in additional cooling solutions, such as better case fans or a more efficient CPU cooler.

    By following these steps, you should be able to mitigate overheating issues and prevent your computer from shutting down unexpectedly.

    Hello, thank you for reaching out to Microsoft Q&A.

    Are your fans spinning louder than normal? If you believe this is due to overheating, first check for dust and debris around the air vents and clean them. Then, remove any nearby objects from around the computer to improve airflow.

    Next, test whether your device shuts down even in the BIOS environment, before Windows starts.

    Turn on your computer and repeatedly press the ESC or F12 key to enter the BIOS screen. Check if your device turns off even while in the BIOS. In the system configuration or power settings section, if available, change the power scheme to Balanced and then save and exit the BIOS.

    If you're still experiencing the same issue, please run a pre-boot UEFI hardware diagnostics test (check your manufacturer's website for instructions specific to your computer) to identify any potential hardware faults on the device.
