Not sure if it has any relation to the My Computer icons missing.
I would recommend using Autoruns and go through all the startup items and see if something is possibly causing the icons to disappear like that.
Not sure what all those things are? Go to HERE for help with identifying those pesky startup items.
Yes, my wife had installed, then uninstalled a webcam (which explains the Logitech part of the error message, I bet).
Your first link is taking me to a site that's not telling me much about the INamesp2.dll and every link there is trying to sell me SpeedUpMyPC (and I'd like to not have to buy one more protection program).
I can't find anything in the other links that deal with Inamesp2.dll and how to restore it (or help the computer find it again). But I apprecaite the help.
