You could get a cable to back up any data off the drive that you may want, that will go from IDE to USB. Then you can use another computer to get your music, pictures, and whatever else you may want to keep. If your hard drive is clicking, you could pay big bucks for some company to get the data off the hard drive, or look in to freezing your hard drive. I would google the freezing before getting started. A friend of mine froze his hard drive and got most of his data back before it crashed again, so it's worth a shot!
Good luck, sorry your compy busted.
