Getting sick of Office 2007 fatal errors...

Every so often MSWord 11 or Excel or PPoint dies upon starting the app.
I have a legit Office 07 Ultimate version, installed in a new PC with Vista
x64. Initially I decided to upgrade to Windows 7, but frequent freezes
continue to happen. All products are updated. Usually the killer is the **
ntdll.dll ** module.

Any MS brilliant idea? This is my last error event:

Perhaps the adobe PDF COM add-in... will try to disable it
