Very Weird dead hard-drive problem. Wont let me power-on PC.

[SuperZ]

When I have the power cable attached to the hard drive (regardless of whether the IDE is attached) the computer will not boot at all and the hard drive will not start up. No computer fan coming on, no monitor turning on, no messages from OS, nothing! I do not have this problem with other hard drives... and in fact, if I have no hard drive connected at all, the pc will atleast power on.

When I tried putting this HD in an external enclosure and turning it on, again it did not spin-up (hard drive made no indication that it was doing anything at all, no noise), however I noticed that on the power supply brick the green led turned off when I tried turning the enclosure on. I tried this on another brand of enclosure, and the same exact thing happened.

I realize this is a very weird problem, and is unlike any other dead hard drives i've ever seen before, but I am desperate for help because there is important school stuff on this hard drive, and I can not afford to pay for "professional" recovery.

What might be causing this problem?
What are my options?

Thanks!
