Can anyone help

about 3 times a week when I turn my computer on the toolbar will not come
up, all I get is a hung up hourglass and nothing seems to help. control alt
delete will not close this down nor will any thing else that I have tried.
the only way that I can get the machine to come out of this is to hold in
the off button for several seconds to turn it off. I am running spybot,
ad-aware and Norton AntiSpam every 10 days and backing up to my external
hard drive.
Any suggestions before I reload the machine which I really don't want to
have to do??
