I have a problem with mysql

when starting the computer before logging in i get loading errors from
the extentions in php.ini

when i have them "uninstalled" then everything is working good
but it can't be right that i need to have it like that because i guess i need some of them like gd2.dll for the thumbs

is it possible that php.ini is wrong configured ??
does anyone have the same problem and what could be done to this ??
