Explorer.exe hangs during startup

Hello,

I have a new Toshiba laptop with Vista home premium. Lately when I
start the computer, it will get me past the log on screen and go to my
desktop and then hang. I'll get an error message that says explorer.exe
hangs. If I click to close, I'll get to my desktop but several programs
that usuallyload during start up will have to be started manually. After
that, everything works fine.

In the Event viewer I find this error info:

I have no idea what all that means, nor how to fix it.

Suggestions Please?!
