    I hope this helps someone as we've spent 2 weeks ironing out this annoyance.

    The symptom we have is randomly the machines are rebooting when the machine is idle. Only when idle. We've consistently and reliably had a whole lab of machines crash in the exact same way.

    Eventlog shows:

    A fatal hardware error has occurred.

    Reported by component: Processor Core
    Error Source: Machine Check Exception
    Error Type: Cache Hierarchy Error
    Processor APIC ID: 7

    How to fix?

    All you need to do is set to Disabled Global C-State Control in the UEFI.

    Specs of lab machines;

    1800X - h110i
    X370-Pro - bios 0515
    32GB (16x2) F4-2666C15D-32GVR
    ASUS 1070 strix
    1tb 960 evo ssd
    1000 evga p2 psu

    We involved AMD and ASUS and after a lot of fiddling we isolated it down to this. AMD were the most helpful. ASUS less so....

    This board doesn't work with POE . Just to save you some more time that Asus won't help you with .
