I have a X10DAC-0 motherboard. My Windows 2012 R2 System Event log is showing the following error every 60 seconds:
Reported by component: Processor Core
Error Source: Corrected Machine Check
Error Type: Bus/Interconnect Error
Processor APIC ID: 16
Please try to unplug the DVD-ROM drive. There's is a chance that the older DVD-ROM drive would be causing the issue with the operating system.
