Possible dying hard drive?

Recently my computer's been making sounds akin to when it powers up, then freezes.
I'm thinking that possibly the older of the two hard drives i have is dying. it's the one that Windows uses to boot up as Gigabyte decided not to give me a SATA driver disk.
Anyway, would a dying hard drive cause that? Sounds similer to it starting up, then freezing?

Any idea for the best course of action. In theory I'd like to keep everything on my SATA drive and just have that, this old one was going to just be for backup (but now is stuck as the boot). I've got in contact with Gigabyte about getting a SATA driver floppy or them telling me which file i need to use from their download.
What about keeping everything I currently have? Would Norton Ghost (or something similar and better) do the trick?

thanks in advance.

The failing/failed hard drives I've had have all exhibited that sort of sound, BlackSkarab. The noise they make is a very noticible 'clicking' (presumably the heads moving into/out of the platter area). I've had three hard drives fail on me throughout the years, each time with that same noise.

If it still runs, I say you should think about running something like Retrospect or Ghost to dump all the data to some other medium (be it a file on your SATA drive or CDR/DVDR), since I can't say I've ever had a drive 'recover' from click 'o death.
