When a virtual server crashes and presents a Purple Screen of Death (PSOD), the immediate response should be to document the incident. Collecting a screenshot of the PSOD is crucial as it contains error codes and state information that can be used for diagnosing the root cause of the crash. Noting the details, especially those that come after the line detailing the OS version, can provide specific clues to what might have caused the server to crash. This is a standard best practice before rebooting the server, as it ensures that there is a record of the event to investigate and potentially prevent future occurrences. A hard reboot should only be done after this critical information has been recorded.
