Seriously, go buy a new hardrive(Not expensive at all $60 tops for another 60gig). Open up the computer and replace the one you have with it and link up the old one to the extra cable you have inside. Get a computer geek friend to give you a copy of windows XP (Using windows 2000 is probably why you're comp is crashing). When it's all installed you old hard drive should show up and you should be able to salvage all the files.
Hardrives don't just wipe clean unless you have a very distructive virus on your comp. The operating system, in this case windows 2000 (really prone to crashes like that), is just screwed. So once you've installed another hardrive and new Operating system, the old hardrive should show up with all the files on it like a normal second hardrive.
I wish I could take a look at it for you and help you out. And don't feel stupid please. That was not my intention. I too was scared of touching or doing anything with the inner workings of my computer until I realized they're just pieces of metal and wires. Make sure you don't have anything actually hooked up when you're fiddling about inside.
