It is possible that one of the drives are causing the proble. Disconnect all drives Hard drives, CD, DVD, BLUERAY,Floppy etx and turn the system on if it boots then shut it down and connect the drives one at a time until you find the one at fault.. If this fails then the problem resides in the main board itself, YOu said you cleard the cmos, try reseating the processor (removing and then putting it back) then flashing the bios (clear the cmos) ,, if that fails then you may need to replace the mainboard.

maybe try taking out the cmos battery located in your case, looks like a small watch battery, that will clear bios settings and start from scratch, if there is no battery then there is a jumper sequence to do this

SOURCE: Bios default password
The BIOS default password is just blank, and it is not asked.
When you set a bios password, you are asked to enter a value, therefore if bios is asking the password, the password had been changed.
To reset the bios password if you do not know the password you need to access to motherboard and temporarily remove battery for few seconds.
Removing battery will reset bios and delete the password.
Unplug power cord before accessing the motherboard, and try not touching the motherboard with your finger.
Put battery back in place before restarting computer.
