Hello all,

 

The event log shows:-

 

DC2019 41 Critical Microsoft-Windows-Kernel-Power System

 

The computer has rebooted from a bugcheck. The bugcheck was: 0x000000ef (0xffffad0a1afd9080, 0x0000000000000000, 0x0000000000000000, 0x0000000000000000). A dump was saved in: C:\Windows\MEMORY.DMP. Report Id: 99486759-3171-41ff-b81f-8fd5b0a72553

 

I know its difficult to determine the error from the above but just wondered if anyone else had come across something similar.

 

I have attached a memory.dmp file

 

I have uploaded log files to HP to assess in the meantime.

 

Thanks all

    discoveranother You've either defective hardware or a buggy driver. The error code means that some critical process died. That most of the time is some 3rd party driver.

    To identify which one use the file C:\Windows\MEMORY.DMP and "WinDBG Preview" from the Windows Store. Than open the file and run "!analyze -v" that often is enough to see the reason for the crash.
