Thanks for the suggestions, Bill...

This was my thought, but it's looking more and more like a problem with Windows 7, not any particular piece of hardware or its driver. And it doesn't happen just during shutdown - it also happens randomly both while using the system and while it's idle.
I saw the symptom initially with just a USB phone handset connected; later, with a Firewire device and the handset, later with only the Firewire device (no handset). So far, at stock clock with no hardware connected, it's doing fine. So far.
Anyway, the problem occurs so rarely that this test wouldn't tell me much - 99% of the time it shuts down fine, regardless what's connected to it.
Also, in the device manager, try showing the hidden devices and removing all the ones that have the problem icon on them.
I've been monitoring this since I suspected hardware. To date, I've never seen a device icon with a problem.
Also, make sure you dont have a USB device plugged in when shutting down.
That'll be difficult - both my keyboard and mouse are USB.
Type GPEDIT.MSC command ...
Verified: Clear Virtual Memory Pagefile option was and is still disabled.
Go to Control Panel > All Control Panel Items > Performance Information and Tools > Advanced Tools (in the left pane). The problem may be shown here.
"No issues reported."
If not, click View Performance Details in Event Log (Event Viewer). I believe events in the 200 series are shut down events. Double-click them and see if there are any clues.
There are quite a few 200s, but none provide any information other than the duration (there's a wide range), degradation flag (some true, some false) and event time. The only interesting thing is that I don't seen any 200s since I went back to stock clock. Then again, I haven't restarted or shut down much since doing that. I'll try a few of those to see if any 200s pop up.
Do you see a lot of networking activity before shutdown? Tweak apps and disable unnecessary services to lighten that.
No idea - haven't monitored that.
In terms of disabling unnecessary services, I'd love to see a list. It boggles my mind that my XP Pro SP3 machine runs fine with only 175MB worth of background processes, while Windows 7 seems to need twice as many background processes and almost a GB
worth of processes and services before I even run a single application.
