Quicksilver turned into broken engine.

[System7]

Well, I was working in OS 9, it crashed and then I heard this horrid Mechanical Fail Noise.

I unplugged it. I plug it back in, and it is the WORST failure sound I ever heard.

Did it eat your chips? ;D

You've got something in the fan… I wouldn't worry that much, since you can hear the startup chime. What's going on, apart from the noise? Does the computer boot? A QUicksilver case is so easy to open: just try and see what's out of place and makes that noise! You can even start the computer with the case open…

I see nothing in the fan.

You're not kidding when you say "broken engine"... sounds like a spun bearing in a V6 engine.

Diagnose it like a broken engine then. Open the case wide open, start the machine up and listen for the horrible noise up close. It'll be either your hard disk or one of the fans. Disconnect the suspected component and see if the noise goes away. Once it does, you've found the problem.

If it does turn out to be the hard disk, you may wish to take the cover off and fire it up with the cover off just to see what's caused that awful racket. Although for a sound like that it would have to be nothing short of a broken actuator arm.

Just from the fact alone that you said OS 9 crashed exactly prior to the noise, i'd say the hard disk has self imploded in a BIG way. The sound of it clunking and spinning down at the end of the audio clip sounds very metallic, like metal on metal. You wouldn't get this kind of sound with a plastic fan, that's for sure, but you would get the exact sound from a disk platter.

Best of luck.

Holy crap that's a loud and scary noise!

It's definitely a fan or a drive.

Sounds like the hard drive.
