Stop Screen Error message when shutting down

[Guest]

I get the following error message occassionaly while
shutting down. If any one has any suggestions on how to
correct same it would be appreciated.

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

DRIVER_IRQL_NOT_LESS_OR_EQUAL

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

If problems continue, disable or remove any 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.
