[ale] Dead Motherboard?

[ofosho at gatech.edu (Omar Chanouha)]

I put a carputer together using an intel D945GCLF2D motherboard. I
installed it and everything worked. Then I unplugged it to the
faceplate on, but when I plugged it back in the screen wouldn't
display anything. So I took it to my bench, unplugged everything from
it, and hooked it to a reliable power supply. Again, nothing. I don't
get any BIOS beeps, nor any LED activity.  If peripherals are
attached, they do get power, i.e. the dvd tray opens, which is
connected via usb. It is so wierd b/c I didn't change anything that
would affect the mobo, nor did I reverse the polarity. Could it be
memory? I don't think so because the mobo guide says it gives
beeps/messages for memory erros. Is the mobo dead? Are there any
possible explanations as to why this happened, so I don't do it again?

Thanks,
