Default Electrical problems

On 5/7/2008 4:15 PM Mikko Peltoniemi spake thus:

So I was on the computer, then all of a sudden I hear BOOM, like an
circuit breaker tripping, and everything went quiet. The computer
was off.


Some questions that I assume others would want answers to as well:

o You said "BOOM", but that's not a sound that circuit breakers normally
make. What kind of sound did you actually hear when the power went off?

o Any chance that there's a GFCI (ground-fault protected) outlet
somewhere in your house that tripped? It's possible that your computer
outlets are connected downstream of that outlet, on the "load" side, and
that's why the breakers are all on but you don't have power. (It
probably shouldn't be wired that way, but it does happen.)

o If what you said you did to check your breakers is accurate, in that
they all seem to be powered on, then there seem to be 2 possibilities:

1) There's another panel somewhere with more breakers in it, and one of
them is tripped.

2) There's been some damage to a circuit, resulting in partial
disablement of that circuit. Could be a blown wire inside a junction
box, etc.

Sounds as if you would do well to get a licensed electrician to look at
things.
