Constant tone when operating

Computer emits a constant tone when running. Display and computer seems to function properly but the tone exists. What causes this and should I be worried?

    The tone also exists when the computer is shutdown with power still supplied to the Power supply. Is this still the same issue?

  • david_lovern Jun 16, 2009

    All memory and the graphics card were removed and the low constant tone did not stop.
    I removed the battery and unplugged for >10 mins. I even used air to blow out the slots. After restoring the system the low constant tone is still present. Upon startup the tone sounds like a modem connecting then shifts to a low constant tone. The computer seems unaffected. Initially I said it was a constant tone and you called it a beep. It is not a beep at all. It is more like a constant siren wailing but at at very low level. What is the next step, if any?

    I looked into the bios and could not identify anything that resembled chassis intrusion alarm. If it is in the bios I could not locate it. What do you suggest?

Hi,
A constant beep usually indicates that there could be a loose card in the case, check that memory is seated properly, also check your graphics card and any PCI cards that are inside the case are seated properly.


Good luck

    while the computer is off start to remove the memory, graphics card etc and see if the beep stops.
    If it still beeps remove the motherboard battery and the power cord for 10 minutes, then put back all the components and last of all the power cord, see if that helps.

    The only thing i can think of it being now is the chassis intrusion alarm, you can disable this by going into the bios and stopping it from sounding.
    Try that!!

Computer monitor cycles on and off when the computer boots up but seems to have constant power when just turned on


The boot process goes through various display modes. Each time it switches, the monitor has to set itself for that mode. This causes the monitor to flicker while it's adjusting. Perfectly normal operation.

Dell xps 9100 constant beeps upon startup



Beep Codes
Your computer might emit a series of beeps
during start-up if the monitor cannot display
errors or problems. The following repetitive
beep codes help you troubleshoot problems
with your computer.
NOTE: To replace parts, see the Service
Manual on the Dell Support website at
support.dell.com.
One beep - BIOS ROM checksum failure;
possible motherboard failure
Contact Dell (see "Contacting Dell" on page 53).
Two beeps - No RAM detected

Remove the memory modules, reinstall
one module and restart the computer. If
the computer starts normally, reinstall anadditional module. Continue until you have
identified a faulty module or reinstalled all
modules without an error.

If available, install memory modules of the
same type in your computer.

Three beeps - Possible motherboard failure
Contact Dell (see "Contacting Dell' on page 53).
Four beeps - RAM read/write failure

Ensure that no special memory module/
memory connector placement requirements
exist (see the Service Manual on the Dell
Support website at support.dell.com).

Verify that the memory modules that you are
installing are compatible with your computer.

Five beeps - Real Time Clock failure
Replace the battery.
Six beeps - Video BIOS test failure

One long beep tone---NO Display on monitor(monitor checked ok)


Definitely not your monitor. It is either a CPU or a Memory problem, is this a new build or did an existing computer suddenly start doing this?

Is that your motherboard, the Gigabyte 7VM400M ?

My hp w1907 monitor is constantly auto adjusting every 1 or 2 seconds. Make it stop.


Good morning! Auto adjustment occurs when resolution or refresh rate of the display changes. Check your display setings in OS. Set them properly according to product operations manual. Update your display adapters driver. Also check your VGA card or motherboard display port & try using a different cable. try pluging the monitor to a different computer or plug in a different monitor with your motherboard or VGA cards display port. best regards
