Ken and Marco,

Thanks for your responses. I'm pretty sure the duplicate DLL warning
is superfluous, as both paths point to the same file.

As far as a Logitech camera driver is concerned: I have a camera
driver, and I have Logitech devices, but I have no Logitech camera.

I avoided troubleshooting loaded drivers (even though that tack would seem
 to be obvious given my success in Safe Mode) because I've no idea how
to go about doing it. I've unplugged all of my peripherals and
rebooted, but that had no effect.

Any advice on the best way to isolate a problematic driver on a
Windows 7 system? Is there a way to "dynamically" load and unload
drivers from the
system without rebooting?

Regards,
Casey
