    Is this a physical machine? Have you tested the power supply, power cord and outlet to ensure they are all good? You should also confirm the pull on the PSU. If the PSU is going bad, doesn't get enough voltage from the wall or has a drain too close to its max then it'll trip which reboots your machine. Then Windows generates a power error indicating it lost power.

    If you have a UPS on the server then this will help eliminate issues from the wall to the computer.

    Hello @Kelvin Kamachu

    First of all I would recommend to update all the firmware drivers, and check for any Power Plan settings that might make the computer to lose power or enter an unauthorized sleep state.

    Additionally, Please check in System Event Viewer, for other related errors or warnings at the moment of the restart.

    After that I would suggest continuing with this approach to troubleshoot Event ID 41:

    Hope this is useful in your case,
    Best regards,
