SYMEFA.SYS BSOD

I don't know who to turn to, Norton, HP, Microsoft, or Dell.  I get a blue screen with SYMEFA>SYS PAGE_FAULT_IN_NONPAGED_AREA.  When recovering Windows gives a bunch of BCP codes and does a minidump.  This might be related to a USB drive (HP v125w 16 gb flash) that doesn't work on my Dell XPS 420 running Vista Home Premium or it may coincidental.  Since A lot of you think it's related to NIS I thought I'd drop a note here and see what happens.

 

System Information:

Dell XPS 420

Windows Vista Home Premium V6.0 (build 6002: SP2)

Background:

Has been happening for the past several weeks on my wife’s computer.  My laptop runs fine.  I first saw the blue screen when I put a new HP 16GB flash drive into the USB port.  Coincidence?  I am also running a WD external hard drive as back-up (FYI).  There isn’t any pattern to when the blue screen appears although it does it every time I plug in the 16GB flash, so I don’t do that now.  The Windows error message checks for updates but doesn’t report anything back or prompt me to send to Microsoft.

 

Blue Screen Text:

A problem has been detected and windows has been shut down to prevent damage to your computer.

SYMEFA.SYS

PAGE_FAULT_IN_NONPAGED_AREA

If this is the first time you’ve seen this stop error screen, restart your computer.  If this screen appears again, follow these steps.

Check to make sure that any new hardware or software is properly installed.

If this is a new installation, ask your hardware or software manufacturer for any windows updates you might need.

If problems continue, disable or remove and newly installed hardware or software.  Disable BIOS memory options such as caching or shadowing.  If you need to use safe mode to remove or disable components, restart your computer, press F8 to select Advanced Startup options, and then select safe mode.
