I booted my pc today and it makes 1 long sound,not a beep more a long tone for about 3/4 seconds then stops,during this time the pc continues to boot,but the monitor doesnt come on,at first i thought the graffix card was iffy but i checked both the card and the monitor on my sons pc and they both work ok,can anyone shed any light on what my problem may be.

Where is the noise coming from?

i.e.

mobo

hard drive

etc etc.

From the system speaker as far as i can tell.

I have just had the side off to see if the fans were all working and booted without the monitor connected and it booted and didnt make any sound at all so i dont know what to think.

I just tried my sons monitor on my pc and it booted fine,so i have to think there is somthing amiss with my screen,but it works fine on his pc,he will be in from school shortly so my replys may not be so quick as he wont want me on his pc all the time lol.

I presume you have an AMI Bios setup?

The one long beep normally indicates that all tests have been passed on boot up. See:

You can check out Award etc Bios codes here as well if you don't have an AMI Bios.

I know what the bios beeps are,mine does 1 beep at boot up it has always done this,but the sound i was getting was not a beep it was a tone,i have had another look at it and i thinki have found the trouble my monitor has BNC connectors and the video connector i think is faulty when i waddle it about the monitor comes on and i dont get the tone anymore,as it is now i have got the pc up and running by waddling the video wire it would seem my mobo know when the monitor is not working and makes a tone accordingly.
