something in my case makes a snapping sound
At random times, I hear a metallic snapping sound, repeated several times, from somewhere in the front of my case. I believe it's the same sound as when the computer finishes shutting down. Has anyone else had that happen? Any idea what it means? Electrical problem of some kind?

Do you have a floppy drive installed? They can make a lot of noise at times you wouldn't expect.
|
Nope...can't be the floppy drive. I never connected it.
I hate computers. There are so many things wrong with mine that if I noted them here, someone who is not a computer nerd or a professional would stop reading because they needed sleep. |
could be your HDD head
|
Hard drive spinning down?

I would check for cables getting caught in a fan. I don't really know how to define "snapping sound". Are we talking a branch snapping, or more of a clicking?
|
Better check 'smartctl -a /dev/sda' if you have SMART enabled. If attributes are failing, then it is failing. You can also do a long test and wait till it's finished 'smartctl -t long /dev/sda'.

Anyhow, it's doubtful that you have it enabled. Usually (unless you're installing on a laptop and the installer picks up on that) it won't set that kind of thing up by default when you install for the first time. |

Last time my parents' computer started making clicking sounds the hard-drive crashed and died about a week later.

Anyway, I would suspect anything with moving parts, such as drives (CD, Floppy, HDD), and fans. |
What do I mean? I mean that unless the listener was a computer nerd or a professional (thereby having a strong interest in listening), anyone I told my computer's problems to would stop reading because it was keeping them up all night and they needed to go to sleep. That is my way of suggesting that my computer is a piece of junk with a very long list of problems.

now is your opportunity to listen closely to the noise being made so that you can identify it in the future. your next step is to take a look inside and see how much muck is in there. if you haven't cleaned it inside in the last six months, you may find that one of the fans is a bit gummed up and has a sticking point.
with your ear close to the machine, move around and see if you can discern from where the sound is coming. figure out how to describe the perceived location. if you're chary of ripping it open and peering inside, welcome to the club. after the first few daunting steps, it soon becomes second nature to strip 'em down, clean 'em up and bung 'em back together, moderately confident the blighter will work. places to listen for sounds is the back (usually top of one side) for power supply, which has a fan; on the motherboard, where more fans may be sited, at least one; at the front, below the cd player is the hard drive(s) (usually). there may be other fans inside the case and visual inspection, along with your lugholes, should reveal them. have a good listen. take a break. have another listen. rinse and repeat until you grok it. report back. gluck. :) |
Just kick it really really hard. That fixes all issues, even people issues at times. ;)

As someone said in another thread, "Computers are like horses: they sense fear and take advantage of you." Or it could be a giant cockroach trying to get out ... :eek:
Seriously, I'd suspect a fan or the hard drive. |
Or it could be Cthulhu rising...
Do you have Necronomicon in your HDD...? :D Now seriously... take the PC to an electronics shop, aan have the fan cleaned... sometimes the build up of dust gets in its way... |

So you can't just take the cover off yourself and blow on it? |
If it is a Laptop I wouldnt do that without having the proper tools to do this...
Gloves to take care of statics, etc... But if this is a regular desktop, I would do this myself... :) |
Somehow a laptop never came to mind...
I guess it still wouldn't hurt to blow some compressed air into the vents. |

The power supply is another thing which can make that sort of sound when shutting down, and it can make that sound before failing as well. Might want to look for a screw loose while you're cleaning the dust out. Might want to look for a screw loose around here too....
