Trouble booting, Event Viewer Error ID 65535

What is this error?

 

"The Description for Event ID (65535) in Source (STacSV) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer.  You may be able to use the ?AUXSOURCE=flag to retrieve this description: see Help and Support for details.  The following information is part of the event: Connection to BassMgrHDA COM interface failed."

 

See Help and Support??? My subscription is still valid but I cannot find support for this error. This ID 65535 is not in the archives. I have used Norton for years but I'm now considering changing since I can't CONTACT anyone about this without PAYING?

 

Event Viewer only shows this error.

I have been having trouble booting up, hangs after Windows splashscreen.

OS repair did not show errors.

 

XP SP2

IE ver 6.0 something

NIS 2009

 

Can anyone help?
