Is there an application associated with the message?

For instance c:\Windows\System32\yourapplication.exe

If there is an application then you can use msconfig

http://www.perfectdrivers.com/howto/msconfig.html

See if that application is listed in the startup application.  You may be able to remove it.

Thanks

>>>ntvdm cpu has encountered an illegal instruction
Ntvdm is a windows 16-bit programs or process that is used when you run any 16-bit application. NTVDM CPU means NTVDM Structure has been corrupted...you need to repair it using the following: -

***Quote***

The NT Virtual Dos Machine and the Windows On Windows subsystem are used to run older 16 bit software applications. Below are some trouble shooting steps

   1. Check the Autoexec.nt and Config.nt for anything unusual or anything that can be commented out (in the %systemroot%\system32 directory).
   2. Rename Autoexec.bat (e.g. c:\autoexec.bat).
   3. Check for changes in Win.ini or System.ini, or replace by expanding the original files off of the installation media. (%systemroot% directory)
   4. Rename all other *.ini files if possible
   5. In the Config.nt file, allow only:
      dos=high, umb
      device=%SystemRoot%\system32\himem.sys
      files=60
      shell=%SystemRoot%\system32\command.com /e:4096

If you still have problems checkout Knowledge Base article http://support.microsoft.com/support/kb/articles/q196/4/53.asp which has more information.

These files are also on the Emergency Repair disk so you could just copy the versions from the disk over your existing ones which may fix the problem.

This can also be caused by a virus, for example "NYB" in the boot sector of the machine. (PC has a bootable DOS and a bootable NT partition).

the error does not reference any particular application.  My customer is able to click ignore and proceed to working.  I will try the suggestions posted and get back to you.  Thanks folks.

Yes...you need to worry about the errors...sometimes if the NTVDM module is not loaded properly application and data both may corrupt.

Let me know.
