Shdocvw.dll error

[Jerry]

I am getting an error on boot up that states:

Error Message: "Explorer Has Caused an Error in
Shdocvw.dll. Explorer Will Now Close"

I viewed the web page in the knowledge base but it really
doesn't provide a cure. When I hit the start button the
computer shuts down and I have no icons on desktop.
Someone please help.
Thanks
