Help! Recommended cures not working for iPod sync blue screen of death

I've tried the measures listed here http://support.apple.com/kb/TS1502

And I've tried removing and reinstalling iTunes as recommended elsewhere and some other recommended home remedies.

But to no avail. For the past month or so (perhaps since the last iTunes update...), about 2/3 or 3/4 of the time when I plug in my iPod Classic (whether autosync is checked or not), I get the blue screen of death. I never had this problem before.
