change speed and efficiency like an eletric motor. Basic
computer knowledge makes that woefully obvious.

Hi...

But with all due respect, that is less than half of the
story.

Imagine this if you will. My system is running as your
refer to it 100% fine. (the power supply is more than
adequate)

Then an additional demand is placed on the power supply,
ie Explorer spins up all HDD's, a cd reader, a dvd reader,
a floppy, and perhaps interrogates some USB devices.

The available current is now perhaps woefully inadequate,
voltage drops, and (in your words), is now 0% fine

Most will say that the system is frozen or crashed.

And they will say that the problem is in opening
Explorer

Take care.
