I recently moved one mile from my original location and after unpacking my system, I tried to boot up.  The power came on but the on button blinked amber, there was a sound of harddrives spinning up but no video.  There are two video cards and both monitors are in good working order.  I opened her up, reseated the processors, the cards, the memory; unplugged and reconnected the DVD drives, floppy drives and the hard drives.  Still no joy. The motherboard appears to be on.  There is nothing coming on on the monitors,  HELP!!!!!!!!!!!!!!!!!!
