f5fstop,
If it's before you get to log in, i.e. before windows has started where you have, then I'm convinced is drivers that are having trouble being started and not just adware or anything like that. Most of the recommendations to uninstall things, and to disable startup services are only really going to be effective if the problematic applications are ones that get started after the windows shell starts and the user is given an opportunity to log in.
