British Siren ??
« on: June 17, 2013, 08:17:38 AM »
Greetings Ladies and Gents, One of our towers here in our office intermittently makes a sound that resembles a british siren. We can reboot the pc and it goes away for a short time, but always returns. I seem to remember that you can diagnose some problems by the number of tones at startup, am I remembering correctly? I thought I'd throw it out there and see what kind of response I got.

It is a AMD machine running XP. TIA!

that's applicable if it wont boot I'm wondering if its a heat alarm  I would look at CPU temp next time it happens or take it apart and clean it out

Thanks Skip, It boots fine, and if you can stand the noise you can work away at the pc with no apparent problems. Will investigate some more and see where I end up.

Sounds like some kind of virus. Is it coming from the speakers? If not open it up and see where it's coming from.

It is a AMD machine running XP.

As far as I am aware AMD is the processor (AMD or Intel). Is the pc a Dell, HP, Or some other brand?

Is it at boot, or is this something that goes on while you're working?  When one of the cooling fans starts going out it makes that sound.  Pull the cover, put your finger on the center hub of the fan if it's on the cooling chip, and it'll stop if that's what it is.  If it's the one in the power supply, I normally stick a zip strip in there to stop the fan from turning and see if that's the one making the noise.

Sorry if I'm totally misreading your post.

Thanks for the replys folks. It is not a brand-name pc. It was a shop built pc. The noise is not coming through the speakers. And, it rarely comes on at boot, it normally takes a few before it starts. Someone else told me that they thought the noise represented processor temp. and to check the BIOS screen for processor temperature. We haven't used the machine in a few days and I haven't had time to open it up. I will post what I find. Again, I appreciate suggestions!!!

we have a PC we use as a media server hooked up to the tv for streaming music , netflix, dvd , etc . it started doing something similar. it would make a loud screaming sound . turned out the fan is on the top of the case and someone had cleaned and turned the case upside down so the fan was on the bottom and not getting any air  circulation , turned it over and and its been fine ever since

I would look for a temp monitor desktop download
