I have no idea why this is happening, but a loud screeching sound is coming from my hard drive. I've had my computer about a year and I noticed the screeching sound shortly after I got it, however I thought it was a fan, and it would usually stop soon after booting. However, I no longer think it's a fan, from what I can tell it's from the hard drive, and now it no longer stops after booting. I have to smack the top of my tower (not that hard lol) to get it to stop, but it's usually for a little bit and then it starts up again. I have no idea what to do with it. Do I need to just get a new hard drive? I'd hate to have to go through that hassle, but I guess I have to do what I have to do. Anyone have any ideas?
