Sure. Is the top a shiny piece of metal an inch or more
square? That's the heatslug. Or is it a dark chip about a
centimeter square? That's a chipback/bare die.

Certainly! The question is how a working chip could have gotten
fried without being removed from it's socket. An AMD could
be overheated, but AFAIK P4's have thermal throttling. And even
without, should have worked once long enough to beep. Most likely,
you dislodged some card, memory or connector.

You have to know what to look for.

This is mostly meaningless. The HD boots by itself when
it's controller does an IPL from a protected track. The mobo
fans/LEDs are hardwired. The keyboard LEDs are _much_ more
interesting, because they're flashed at boot under CPU control.
Ditto for the beeps.
