I have a refurbished Dell Optiplex 755 with WIN7 Pro.  I was moving my modem and disconnected its power for a brief period of time.  The PC was off and I noticed that the DVD device made a noise as if it were trying to boot when the internet/modem was disconnected.  I assumed that if the PC was off it was completely off.  Could anyone give me their opinion as to why it reacted when the modem was powered down.

Unless the power cable is removed from the back of the box you cannot be positive that the computer is completely off.

As stated, residual power may remain, even after unplugging.  See http://superuser.com/questions/283109/why-does-pulling-the-power-cord-then-pressing-the-power-button-fix-a-non-booting, Answer 5.
