If you mean touching the momentary power switch on an ATX type of power supply, that may turn the power supply off, it might put the box into standby mode. It's configurable. > and the screen stayed black, did that again, and the same thing happened.

When you tried shutting down again? On some hardware it doesn't probably shut down, the process gets stuck after the shutdown of the OS. In the past I had to add kernel parameters to change the power mode (APM, ACPI, etc.), for some of my motherboards. > The reason I don't like this is because it could have shot my BIOS, I > think, not sure though.
