First thoughts from the mp3, knackered hdd.
I had similar symptoms on a friends computer, I couldn't get into the disk, wouldn't boot from from anything, recovery, Linux, Dvd, nothing. (changed and ultimatley reset BIOS to defaults also)
A safe mode boot would display crcdisk.sys as the last item loaded. If I tried to boot it normally it would just hand in the same way you describe.
" To test that theory, I removed my hardrives and used another one from a different computer that was made around the same time as my other HDDs. Still, no proper boot, and it made the exact same sounds."
You cannot expect a hard drive removed from another computer to boot your own, unless you have the exact same system spec. Different hardware involved, different drivers, software etc. Far better to place your suspect drive into a friends proven working computer, as a secondary data drive if possible (grab your recoverable data from there) if installing your problem hdd into a known working system as a secondary data drive causes that pc to crash, then the problem is most likely with the hdd in question.
a crcdisk.sys fail will most likely crash the system regardless and effectivley means that the drive is indeed "knackered"
Just my thoughts
