SpectreWolf,
It most likely means that one of your automatic startup programs is not finding its related piece of hardware when it starts.
(These are mostly the O4 entries in your HiJackThis log)
You can troubleshoot it fairly easily with Winpatrol.
If you right-click the scotty dog icon from Winpatrol and choose Startup Info, it will list all the automatic startups.
You can disable any of them, or do so one at a time, and reboot until you discover which one is complaining.
If you disable one and want to put it back on "automatic startup", Winpatrol makes that easy to do also
