download fallout mod manager and then click the check for conflicts button and also click the sort load order button.
If it's anything like OBMM for Oblivion, that doesn't do you any good. If anything from the Fallout.esm has been changed in anyway it will show up as a conflict, making that info meaningless. I'm not sure if the parameters it uses have been improved since Oblivion, but I strongly suspect it hasn't.
