You may receive the following Stop error message in Windows XP:
The four parameters inside the parentheses may vary.
STOP: 0x0000009C (0x00000004, 0x00000000, 0xb2000000, 0x00020151)
This behavior occurs because your computer processor detected and reported an unrecoverable hardware error to Windows XP. To do this, the processor used the Machine Check Exception (MCE) feature of Pentium processors or the Machine Check Architecture (MCA) feature of some Pentium Pro processors. The following factors may cause this error message:
Use the Windows Error Reporting toolWhen this error occurs, use the Windows Error Reporting tool. With this tool, you can send the error report directly to Microsoft, and then the tool will report back if a fix or a workaround is available. To use this tool, follow these steps:
Contact your hardware manufacturerYour best bet may be to contact your hardware manufacturer or a computer hardware technician for help with troubleshooting this issue. The manufacturer may have some additional steps to try to diagnose this problem. The manufacturer will be able to determine whether the hardware has to be repaired or replaced.
A machine check exception occurs when Windows XP and your hardware platform cannot recover from a hardware error so that the system can continue to run successfully and reliably. More specific diagnosis of machine check exceptions is difficult, and there is no general solution. Contact your hardware manufacturer or a computer hardware technician for help with troubleshooting this issue.
Machine check exceptions are frequently caused by one of the following conditions:
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 XP reports that the error occurred and displays parameters that you can use to decode the exception. Contact your hardware vendor or processor manufacturer for information about the Machine Check Architecture, or see the Intel Pentium Pro Family Developer's Manual - Volume 3: Operating System Writer's Manual.
