Understanding and troubleshooting the "Stop 0x0000009C" screen

Symptoms

A computer running Windows NT Server or Workstation shows the following Stop error code:
STOP: 0x0000009C (0x00000030, 0x00000002, 0x00000001, 0x80003CBA)
NOTE: The parameters for the Stop message may vary from the parameters shown.

Cause

The computer processor detected a hardware error and reported it to Windows NT using the Machine Check Exception (MCE) feature of Pentium processors or the Machine Check Architecture (MCA) feature of some Pentium Pro processors.

More Information

Windows NT Server and Workstation version 4.0 now have the ability to report exceptions generated by the MCE or MCA features.


The Pentium and Pentium Pro processors provide a mechanism to detect and to report hardware-related problems such as memory parity errors and cache errors. To signal a hardware error, the processor signals the detection of a machine check error by generating a machine check exception (Interrupt 18). Windows NT simply reports the fact that the error occurred and displays parameters that you can use to decode the exception. Contact your hardware vendor or processor manufacturer for information regarding the Machine Check Architecture or consult the Intel Pentium Pro Family Developer's Manual - Volume 3: Operating System Writer's Manual.


Technical support for x64-based versions of Microsoft Windows

Your hardware manufacturer provides technical support and assistance for x64-based versions of Windows. Your hardware manufacturer provides support because an x64-based version of Windows was included with your hardware. Your hardware manufacturer might have customized the installation of Windows with unique components. Unique components might include specific device drivers or might include optional settings to maximize the performance of the hardware. Microsoft will provide reasonable-effort assistance if you need technical help with your x64-based version of Windows. However, you might have to contact your manufacturer directly. Your manufacturer is best qualified to support the software that your manufacturer installed on the hardware.
