I really do not have a definitive answer for you, but here are a few 
comments for what they are worth. Try pressing the DEL key as the 
computer is starting. It may go to the BIOS before it becomes non 
responsive. The power supply could be defective and only be supplying 
power for the POST but not for the drives. The CMOS battery could need 
to be replaced and with your setup, the default CMOS may be in conflict.

I hope this helps or at least leads to more ideas.

Its about a year and half old.  It will not go past the first signal it will tell me to  press del or F8 -- I tried pressing those options nothing happens as it stops right there.
