XP: Persistant surte.exe & NTVDM CPU Error

[PJ]

I'm running XP Pro with the latest updates from the
Microsoft website and I am getting a pop-up error about
every 30 seconds that states:

16 bit MS-DOS Subsystem
C:\WINNT\System32\surte.exe
The NTVDM CPU has encoutered an illegal instruction

'Close' 'Ignore'

The system is just idling and this pop-up occurs and
stacks the pop-ups on top of each other. Only by
repeatedly clicking the 'Close' button can I eliminate
them.

The event viewer is no help. Similar information as on
the pop-up without indicating exactly which application
induced the failure.

This error occurs shortly after booting and manifests
itself whether I log on or not and whether or not I am
running any applications.

Any insight would be greatly appreciated.

Thanks,

PJ
