In the debug output, look for:
Use the Event Viewer . Look under Windows Logs > System for "WHEA-Logger" events. This will often provide a "Section Type" (e.g., Processor or Memory) that identifies the culprit.

If your server reboots silently without a BSOD or kernel panic, suspect hardware and force-enable MCE logging in your BIOS (often labeled: "MCA/ECC Logging").
A , often presented as a "Machine Check Exception," is a severe hardware-level error. This error typically occurs on high-performance servers (such as HPE ProLiant Gen10) or workstations, indicating that the processor has detected an internal, uncorrectable error, often related to the PCI Express bus or memory sub-systems. In the debug output, look for: Use the Event Viewer
Modify the workload profile in the BIOS. Changing the profile to or similar performance-oriented settings can sometimes prevent the processor-to-PCIe bus contention that triggers the exception. 4. Check Physical Hardware (PCIe Cards)
If the previous steps fail, you must stress-test your components individually. : A financial trading firm reported recurring x64
Component failure due to overheating or unstable power delivery can trigger the exception.
