Hi,
My computer is making a strange siren type noise coming from the TOWER. My computer is an Intel P4 2.4 with 256ddr pc2100. It has a CD/RW and a 20 g Western digital ATA hard drive. The noise sounds like some sort of alarm. I always shut the computer down when it comes on. I thought it was overheating, but I checked the fan and it is running and the casing is cool to the touch. I haven'e been able to find any reference to this sort of sound. Are there built in alarm sounds for failing componets? It happened a few times last summer and then started up again a few weeks ago. It's becoming more and more frequent. When I shut it down the noise usually goes away while windows is shutting down and before the computer actually turns off.
Any help would be greatly appreciated.
thanks,
FrenchycatzHow strange. Does this happen when you perform a certain action? Which operating system are you using? Do you have virus and Spyware protection? When did this start? Have you made any changes to your system recently? Are you sure this noise is coming from the tower and not the speakers?

FlameYes I have spyware and Anitvirus protection and they are all updated and running. At first the noise was random. I defragged the hard drive and it made the noise. I can almost count on it to make the noise when I'm playing a maj jong GAME. It also happened once when I was trying to use adobe reader and the whole system hung up. Otherwise there SEEMS to be no reason. Strangely enough it has not gone off today. I use Windows XP home and have looked on their website and came up with nothing helpful. The alarm is coming from the tower. I crawled down on the floor and HEARD it. I also turned the speakers off to be sure. I use Firefox as a browser, but this has happened offline as well. I did have it hooked into a UPS but the batteries gave out on it and the whole thing is now on a six shooter til I can find a place to replace the batteries. I had thought it might be the cause.
