Help: Computer making bell noise constantly

I have scanned my computer with two different anti-virus software programs. It's the noise you hear when you open a window. This ding dong noise continues every 2-3 minutes. How do I get rid of it without muting the sound?

I actually timed the noise....it's dings for 6 sec. then 4 sec. almost continually. I went to my Control Panel: Sounds & Audio Devices Properties....then to Sounds....Program Events....Default Deep....and found it to be the same sound as the Windows XP Ding.

On another note:
Yesterday someone hacked into my Yahoo account and sent a message to all my contacts requesting $. I can not receive messages or send them. My guess is that they are being retrieved by the hacker.

Could this have some thing to do with the Ding? I am clueless.

 

Knowing what OS and service pack would be a minimum for any one to help you with specificity.

In Vista,
Control Panel>Personalization>Sounds
You could disable it here, but wouldn't solve your problem.
You should first check to see what sound is the same as what your hearing.
It lists what each sound, if native to Windows, is for, and may help in narrowing down the culprit.

 

Info on the computer:
Intel(R) Core(TM)2
Duo CPU
E7400@2.80 GHz
7.18 GHz, 1.98 GB of RAM

There is no make and model because the computer was built by a computer technician.

I am using MS Windows XP Professional Version 2002 Service Pack 3

The dings started approx. one week ago.

Yesterday, my email account was hacked into and all my contacts were sent a message requesting $. I cannot receive or send emails from this account. Well, technically, I can send them....but they are never received by the person addressed.

Since then I have set up a new email account. Could this all be related?

 

The ding is just a wave sound associated with an event, knowing what event the sound is linked to can help in your description of what's happening.
A mouse click is an event that triggers a sound to be played, a .wav file.
That .wav can be used for one event or more than one event, from mouse clicks, window opens, window close, there are many events.
It could be access error message event depending on privilege.

JRViejo's advisement is superior to mine and will provide you with a speedier solution.

Make sure you create a back up of your current setup with at least something like Paragon back up express. If any fix or solution creates a worse issue you can return to a working state with the back up. It's faster to restore an image than to reinstall Windows.

 

I scanned my computer with Malwarebytes' Anti-Malware, found 4 infected files and removed them. After rebooting, my STOPzilla came up with 10 more infected trogan files. I still have the same bell sound.

In regard to your questions:
I use Yahoo for my email accounts.
I've been spending a lot of time on Facebook looking for HS classmates for our reunion. I do spend a lot of time on the computer now that I am a retired teacher.
I haven't downloaded anything new except for a book from audible.com

Could my sound card be bad?

Thank you for your help.

 

yes looks like asocial network gift..after removing viruses,infections in malwarebytes you also "have" to empty system restore.
check also hitman pro ,think is free for 30 days...clean your sytem with ccleaner[3 passes] or bleachbit.
-you need at least free sandboxie,or bufferzone,prevxsafeonline to surf the net.
or just say bye to facebook.

 

I want to thank everyone for their help. Your many suggestions were helpful in removing the beeping sound (it was getting to be extremely annoying). I do intend on having my computer technician check to see if anything else is hiding within my system. It is so nice to know that this forum is available. Even more importantly, that you were able to put the advice in simple language. Thank you again.
