Bstmpires,   We normally don't support OS issues, but in my opinion, and from reading on the error, I would suggest updating the server on firmware and drivers. You can do a lot of them using the platform specific bootable ISO found here. I would also verify that the chipset, bios, and nic.   Let me know how it goes.    
Hi all, In the last few weeks I have had several crashes on my R640 poweredge server.The error that appears in windows events is 41 Kernel-Powel (0x8000400000000002).BSOD does not appear, goes black and boots again.There are days when nothing happens and there are days when it goes down 3 or 4 times.The server has windows 2019 installed.Can anyone help in this matter? - System - Provider [ Name] Microsoft-Windows-Kernel-Power[ Guid] {331c3b3a-2005-44c2-ac5e-77220c37d6b4}EventID 41Version 6Level 1Task 63Opcode 0Keywords 0x8000400000000002- TimeCreated [ SystemTime] 2021-05-14T08:15:35.732628300ZEventRecordID 527567Correlation- Execution - ProcessID] 4[ ThreadID] 8Channel System- Security [ UserID] S-1-5-18 - EventData BugcheckCode 0BugcheckParameter1 0x0BugcheckParameter2 0x0BugcheckParameter3 0x0BugcheckParameter4 0x0SleepInProgress 0PowerButtonTimestamp 0BootAppStatus 0Checkpoint 0ConnectedStandbyInProgress falseSystemSleepTransitionsToOn 0CsEntryScenarioInstanceId 0BugcheckInfoFromEFI falseCheckpointStatus 0 Thanks
