i had similar problems after installing macafee av, really slowed down my startup. had to do a full recovery in the end.
have you tried msconfig?
just about every program u install will set itself to run at startup when u probably don't need it too.
if you tidy up your start up it might help.
click: start, run,...........then type
msconfig and click the startup tab...........have a look for programms loading at startup and uncheck any that u are SURE that u don't need. then reboot.
i'd think about NOT having oe and dial up and that drive checker at startup unless u really need them, and unless u use messenger get rid of it too.
