Anybody have a clue as to why my Delta 1010 won't power on? Its on a Giga PC that worked fine a few days ago.

I know the DB25 cable and the power supply must be connected. I swapped both, but still no power. The PC see's the card. The M-audio control panel software works fine. I can see that the 'monitor mixer' reads an input when I play Giga samples. I can also hear stuff okay out of the SPDIF output of the 1010 card going into my Mac/Pro Tools box. its just the darn break out box won't turn on.
