Hello CPU machine checks are errors detected by the CPU. They are generally caused by drivers. They can also be caused by memory, system board, or the CPU/memory controller. The operating system is stating that this is a hardware issue because the processor halted the system when it encountered the non-maskable interrupt. The CPU was not able to recover from the error so it halted the system creating a blue screen. The dump files just point to the cause of the halt which is the processor. I would suggest checking the hardware log within the BMC for any memory errors that occurred at the time of the blue screen. If the same memory is producing errors when the blue screens occur then swap the memory around to see if the errors follow the memory, stay with the slot, or stay with the CPU/memory controller. If you installed a driver for virtual or physical hardware around the time this issue started then that driver is likely the cause. I would update the driver if possible or uninstall it to see if the issue stops. Thanks
I'm trying to track down why this server is experiencing blue screens. I see the following errors in the event log: Error Event ID 6008 "The previous system shutdown at 4:21:28 AM on 6/9/2015 was unexpected." Critical Event ID 41 "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly." Error Event ID 1001 "The computer has rebooted from a bugcheck.  The bugcheck was: 0x00000124 (0x0000000000000000, 0xfffffa800a62e038, 0x0000000000000000, 0x0000000000000000). A dump was saved in: C:\Windows\Minidump\060915-24913-01.dmp. Report Id: 060915-24913-01." Error Event ID 1500 "The SNMP Service encountered an error while accessing the registry key SYSTEM\CurrentControlSet\Services\SNMP\Parameters\TrapConfiguration." Error Event ID 7026 "The following boot-start or system-start driver(s) failed to load:  ClusDisk" Error Event ID 18 "A fatal hardware error has occurred. Reported by component: Processor Core Error Source: Machine Check Exception Error Type: Internal Timer Error Processor ID: 0 The details view of this entry contains further information." If it helps, here's a couple of links to the dump files generated after the BSOD: Here is a link to the dump file: [URL] Here's another dump file from when the BSOD occurred again 5 days later: [URL] I've checked the web based "megarac" software to look for any error logs or any information on issues with voltages, temperatures or fan speeds and everything appears to be within normal levels, no BMC errors. MegaRAID storage manager shows an optimal array. I don't currently have a good monitoring solution for RAM, PSUs or CPUs. Still looking for one. Can anyone here help point me in the right direction to figure out what's going on?
