add new hardware wizard

I'm running windows XP and using a HP Deskjet 960c
printer, connected by USB.

Recently the PC had all its devices unplugged and was
relocated and then everything plugged back in. When that
happended it found new hardware, specifically the printer.

I ran through the wizard but I couldn't install the
printer as the wizard said that the "specified port was
unknown". The printer was still in the control panel from
previous and it still worked, but the add new hardware
wizard pops up everytime the PC restarts.

All printers and drivers have now been removed and re-
installed (via the installation CD) and that gets me a
working printer but the add new hardware wizard still
appears on start up.

How can I remove the wizard from appearing everytmie I
start the PC, the printer is completely uninstalled and
not even physically connected to the PC, yet ti still
finds new hardware !!

Any help would be appreicated but I'm a beginner so please
make your advise step by step.

thanks, Sam
