User Replied on August 13, Hi,. This error indicates that there is a hardware problem. A machine check exception indicates a computer hardware error that occurs when a computer's central processing unit detects a hardware problem.

Some of the main hardware problems which cause machine check exceptions include:. Hope this information is helpful. Please post in case you have any further issues, we are happy to help you further.

Windows then calls into the PSHED so that it can add any additional hardware error information to the error record to better describe the hardware error condition.

After Windows has compiled all of the hardware error information into the error record, it logs the error information in the system event log and notifies user-mode applications by raising an Event Tracing for Windows ETW event. Under certain hardware error conditions, the operating system is forced to restart the system to recover from the error. In these situations, Windows does not log the error information in the system event log or notify user-mode applications until after the system has been restarted.

Therefore, the operating system must save the error record to some form of nonvolatile storage before restarting the system. The PSHED provides an interface through which the operating system can store and retrieve an error record so that the error information is preserved during the system restart.

If a PSHED plug-in is installed and is registered to participate in error record persistence, the PSHED plug-in can provide a platform-specific implementation for storing and retrieving error records. When the system is restarted, the operating system retrieves the saved error record so that it can be properly logged in the system event log and user-mode applications can be notified. Windows also provides a hardware error management API so that user-mode error management applications can set and retrieve hardware error source information, configure the error handling for a particular error source, and inject hardware errors into the hardware platform for testing purposes.

Intelligent Platform Management Interface IPMI An interface that is used to monitor and manage functionality, and that is built into the hardware platform. IPMI is primarily used to monitor the health of the system hardware and to handle environmental error conditions. An LLHEH can be an interrupt handler, exception handler, polling routine, or a callback routine that is called by the system firmware.

All LLHEHs report hardware errors to the operating system through a common hardware error reporting function. Machine Check Abort MCA An exception that an Itanium processor reports to the operating system to indicate that a hardware error has occurred. Machine Check Architecture MCA A hardware and software architecture used to report hardware errors to the operating system.

Machine Check Exception MCE An exception that an x86 or x64 processor reports to the operating system to indicate that a hardware error has occurred.

Machine Specific Register MSR A processor-specific register that is used by system software to implement certain functions. Nonmaskable Interrupt NMI An interrupt that the processor reports to the operating system regardless of the processor's current interrupt priority level. An NMI is usually signaled when the platform detects a fatal hardware error condition. Service Processor SP A microcontroller, distinct from the main processor s , which manages platform-specific functions such as monitoring environmental conditions and handling certain error conditions.
