What operating system are you using? Can you get into the OS at all or does this happen each time you start your computer? Have you installed any new hardware, updated any software, or made any other changes recently.
I did find this info from Microsoft.
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.
If you can get into the OS. Check the event viewer for error messages. It would be helpful to see that information.
Hope this helps
Good Luck!
