Troubleshooting a Stop 0x1E or KMODE_EXCEPTION_NOT_HANDLED

Learn how to troubleshoot the 0x1E or KMODE_EXCEPTION_NOT_HANDLED Stop Error (BSOD) in Windows 7.

What caused the error?

A Stop 0x1E message indicates the Windows kernel detected and illegal or unknown processor instruction.  This Stop message is very similar to the 0xA Stop message.

How do I fix it?

  • If you recently installed or upgraded a driver try rolling back or uninstalling the new driver.
  • If the Stop message mentions the file Win32k.sys, the error might be caused by a remote control program.  Try starting the computer in safe mode and then uninstall the remote control software.
  • Try updating the computer’s BIOS.  See the computer manufacturer’s manual for help with that.
  • This Stop message can also be caused by insufficient disk space or memory.  You might need a larger hard drive or more RAM.
  • The problem might be caused by a memory leak.  For more information on troubleshooting memory leaks see the Microsoft KB articles 177415 and 298102.
