Content in this article may not be relevant to you.Visit the Windows 7 Solution Center SymptomsOn a computer running Windows 8 or Windows Server 2012, an NMI (Non-Maskable Interrupt) may be triggered by a user manually pressing an NMI switch on the computer, or due to a hardware error. In this event, Windows stops executing and displays a bluescreen, stating "Your PC ran into a problem and needs to restart." It includes the following error code: NMI_HARDWARE_FAILURE. The computer may then save a memory dump file, and may automatically reboot, depending on the settings specified under "Startup and Recovery" in the "Advanced system settings" under the System control panel. CauseThe behavior when an NMI is encountered has changed compared to earlier versions of Windows. In Windows 7, Windows Server 2008 R2, and earlier versions, the response when the system encountered an NMI was dependent on the configuration of the "NMICrashDump" registry value. For more information about the NMICrashDump registry value and handling of NMIs in earlier Windows versions, click the following article number to view the article in the Microsoft Knowledge Base:
In Windows 8 and Windows Server 2012, this behavior is not configurable. An NMI will always result in a bugcheck 0x80 (NMI_HARDWARE_FAILURE). This is equivalent to the behavior on earlier Windows versions where the "NMICrashDump" registry value was present and set to a value of 1. More InformationThis behavior is by design.
