Computer help: revive HD that won't spin?

revive HD that won't spin?

I have been told that the 2 hard drives on my computer won't spin (therefore not usable in present state).
Anybody have any insight on how to remedy this?

I have a year and a half of digital photos on one of the drives, and various other stuff. Will be holding on to them until I can retrieve the data if possible.

I have been told it can be about $1,000 to have a company rescue the files/whatever is on the drive. I don't have that kind of money.

What happened was this-computer wasn't rebooting after I had installed a serial mouse device, in addition to the regular mouse that was on the machine. This happened even though the first time I booted the computer with them both attached they both seemed to work fine. I understand now this probably isn't a good idea.
The power source blew, and as I understand it took the motherboard with it. This evidently also screwed up the hard drives. I only took it to one computer repair shop, so I don't know if that's the last word, or if that is what mucked things up. For all I know the power source would have blown at this time anyway.
The O/S was win2000, with two HD's, one with a partition. The chip was of some speed (at least a pentium III class)-the machine was put together by a cousin who is too far to come and help, but it was a nice build, and utilised win2000 nicely. Never any complaints before this, no crashes as far as I know.
The setup was esentially basic besides the three drives. One had the O/S, one a copy of O/S source (I think) and the other had all the everyday programs and files used. Had installed the service pack available last August-SP 3 or 4, that included all previous SP's, and many updates since then (until the c-drive became almost full-was tiny, less than 5 gigs).
I am going to try a new motherboard and power source eventually, but I am not really concerned about this machine except for the one drive with the files I want to keep.
Any insight will be appreciated, thanks
