siren noise

At odd times, the PC speaker makes a siren noise - what gives?

Could it be an alarm that the CPU is overheating? Check the temperature settings in the BIOS

that happened to my computer, i was in another room it took me like 10 seconds before i shut it off. Now it won't turn on at all, is tha bad?

i believe you fried your processor, yes, that's bad :(

[fancypiper]

I have had a cpu fan to go bad and make a racket. You might want to check the fans.

Another possibility is that a "Friend" set up your computer to play a siren sound at a certain time ;) Probably not though...

the weird thing is, my pc speakers isn't plugged in, it is broken??? My last computer did the same thing, it would make weird siren noises and then not turn on, but without the speaker being plugged in.

Also it turned it self on before making the noise, it is seriously a ghost machine

do you use any virus software?
someone controlling a trojan could do this.

[toypiano]

nope no virus software? I had no internet connection, accept I guess I connected to the internet once a while ago before everything died. But now this computer has died it is a new harddrive motherboard processor and ram??

A bad hard drive wouldn't stop the computer from powering up, and even with no functional RAM, you'd at least get some effort out of it when you turned it on.

I'd say the first thing to check is the power supply, then the CPU, and if both of those check out, the motherboard.

What Craig said. ;)

OK, it's not a fried processor or dodgy RAM or owt like that.

The 'siren' noise happens while the machine is turned on and working happily - and, other than the blummin annoying noise everything continues to work fine.

Have you tried taking the cover off your case and strapping a giant box fan to the side?

[Crewchief]

I had a old system do the same thing once or should I say still. What I found was it was the hard drive... According to Seagate they put a metal strap that lays on the end of the spindle and after it warms up makes noise. My drive still makes that noise and still works fine. That was over 5 yrs ago. If I was diaging the box I would probably disconnect the drive and boot it into some OS and let it sit there for a while to see if the noise goes a way. Also check your mobo manual if you have one and see if there are any audioable warning signals to the internal speaker.

These are only suggestions. If you give us more info on the hardware it may be easer to diag.

My mobo will beep at me like that if I unplug my case fan.
Check your bios to see what the temps are after the system has been running for a while. That is if your bios has that option. Most of the new ones do. I also have a program supplied by the motherboard to monitor the mobo temps and settings. Other then it is a winblows program.

:D

I'm pretty sure it's not a hardware problem - the machine dual boots linux and Win98. This problem only happens when using linux.
