... Go into msconfig and uncheck all the crap you listed a few posts ago to prevent them from being loaded at startup. Then bring up the services.msc menu.... look for all the items you just unchecked in msconfig and set them to manual, at least for now. Reboot the machine and try and recreate the error.

If you're hell-bent on finding out exactly which piece of crap is causing the problem, then you can one by one recheck the items in msconfig, reboot and try and recreate the error. Eventually, having loaded enough crap, I'm sure you'll come across the guilty stinker.
