This article describes how to troubleshoot a "STOP 0x0000001E KMODE_EXCEPTION_NOT_HANDLED" error message.
A "STOP 0x0000001E KMODE_EXCEPTION_NOT_HANDLED" error message is a common type of STOP error message you may receive on a Windows NT-based computer. A "STOP 0x0000001E KMODE_EXCEPTION_NOT_HANDLED" error message indicates that an error condition was detected by the kernel and Windows NT was unable to continue running because of this error condition. The types of problems that can cause a "STOP 0x0000001E KMODE_EXCEPTION_NOT_HANDLED" error message are very similar to the problems that cause a "STOP 0x0000000A" error message, such as bad pointers, invalid addresses and other types of access violations. The STOP 0x0000001E bug check identifies an error that occurred in a section of code where no error handling routines exist. Note that most exceptions are generated directly in the section of code that is running.
The top four lines of a STOP 0x0000001E generally appear as:
STOP: 0x0000001E (0xAAAAAAAA,0xBBBBBBBB,0xCCCCCCCC,0xDDDDDDDD) KMODE_EXCEPTION_NOT_HANDLEDThe four hexadecimal parameters after the STOP code (0xAAAAAAAA, 0xBBBBBBBB, 0xCCCCCCCC, 0xDDDDDDDD) have the following meanings:
AAAAAAAAA from BBBBBBBB (CCCCCCCC,DDDDDDDD)
Address BBBBBBBB has base at XXXXXXXX - MODULE1.SYS Address CCCCCCCC has base at YYYYYYYY - MODULE2.SYS
Interpreting the ParametersUsually the exception address identifies the driver or function that caused the problem. Always note this address and the date of the driver or image that contains this address.
The first parameter is a Windows NT error code, and all error codes are defined in the Ntstatus.h file (which can also be found in the Windows NT 4.0 SDK). The first parameter tells you the type of error.
The second parameter is also important because it tells you in what code module the error occurred. This can frequently point to an individual driver or piece of hardware that is at fault, which will generally be listed on the third line of the STOP screen.
The last two parameters vary depending upon the exception that has occurred. Typically, you can find a description of the parameters included with the name of the error code in the Ntstatus.h file.
If there where no parameters to the error code, these will be 0x00000000.
For example, in the following STOP error message, an access violation (0xC0000005) occurred in module Srv.sys, which is the kernel mode server service:
Note that no parameters went with this error code.
STOP: 0x0000001E (0xC0000005, 0xFCA733B9, 0x00000000, 0x00000000)
KMODE_EXCEPTION_NOT_HANDLED 0xC0000005 from 0xFCA733B9 (0x0, 0x0)Address FCA733B9 has base at FCA70000 - SRV.SYS
