Is there a system information scanning utility (Like PC Wizard) which will output a graphic representation of the devices installed in the system and the available open slots?
Doesn't look like it has a graphical ("3D") representation function. Info looks like a blend of PC Wiz and Belarc info - both free.
It generates a list of PIDs, the program's location, and the number of visible and hidden icons for each program that has inserted itself into your system tray.
