computer Management and ISS ect ect HELP

I've been trying to figure out how to fix the conflict on port 80 and
straighten stuff out since reinstalling IIS on my new harddrive and all my
other programs....with not much luck

so I went into the Computer managemnt and noticed that I have a folder
called 'other device' and then under that is Multimedia Controller and
Multimedia Video Controller - all 3 have yellow question marks on them...

then under Universal Serial Bus Controllers - it reads like this:

USB Mass Storage Device
USB Root Hub
USB Root Hub
USB Root Hub
VIA Rev 5 or later USB Universal Host Control
VIA Rev 5 or later USB Universal Host Control
VIA Rev 5 or later USB Universal Host Control

can I safely delete the ones with the question marks? so that at rebooting
it will correct itself - and what do I do with all the duplicates under
USB?? can I delete the dupes??

could this be my problem with the conflict on port 80??

thanks
Pam
