I recently had a similar situation; no Bios, no signs of life beside the fans coming on, and a solitary click from the DVD burner.
Finally, after having changed the mother board it turned out to have been a power supply fault, despite the voltages on all legs being correct, even under load. (how odd's that then?)
New PS, nicely overrated, and everything worked as before.
