for yellow question marks? By any chance does it refer to a printer? Any driver's updated lately?...especially from the MS Windows update site? If it's your printer, generally uninstalling it and reinstalling it the next time the wizard show up takes care of this. Yellow question marks are another thing. It can be such as a firewire port on an add-in card you didn't know was there or a secondary video port. If it's a yellow question mark and you're sure nothing new has been added, you can just disable the device to make the wizard give up.
