Power Problem with DVD drive

Hello colleagues.

Recently I started experiencing a problem with the system. when the computer is turned on and off after the hard drive emits unusual noise, as if it runs out of energy, but after totally disconnecting the cable ide as the power of the CD / DVD, the system turns on normally and if I connect again one of the units back to the problem arise.

that will be happening in the board for that to happen and how can I avoid it ?????

I need your help to solve this problem ?????

You might burn to the power supply was damaged by overloading any more than you'd have to prove the source with another unit cdrom that if someone stops by the inflow of energy from yours had some short

the board the disarmament altogether (except the processor and its fan), the review and is not seen nothing burned.
