You are not the only one. I also have random hangs (no BS) even with(out!) all recent OR old drivers (of every hardware!) in EVEN 32 or 64 bits version. Take a look in de admin tools for the logfiles and you'll find 2 main problems (I don't have the details with me now, somthing about Http and something about a security pack kerberos that is NOT needed in Vista).

Clicking on those redirects you to a knowledge base of MS wit all sorts of comments of user having exact the same experiences driving everyone crazy. Before that all my NEW hardware had been exchanged and still it exists.

MS seems to ignore all those uses and even tells to ignore these logfiles / error ("LOL", ignoring an error!) but most of those users even have the newest hardware!
