This happened to me a while back. Try a different HDD or ROM on the same power supply plug. If it works it means your WD Black has kicked the bucket if it still doesn't work then the PSU is kicking the bucket. Alternatly you might be pushing the PSU just passed its limits of what it can power. A computer has higher than normal power requirements during first few seconds of boot (except gaming of course)
What else do you have connected?

I know its weird but yes it can. This has happened to me :) and especially if theres a short circuit somewhere on the circuit board of the HDD. Theres a good chance your PSU is preventing far more damage with its internal protection systems by not turning on.The fact that its brand new and has never worked reinforces my diagnosis :)
