Wierd system beep problem

[romanx]

Any new software installed? Find a machine and start uninstalling software after every beep until it stops

May not track the problem down specificly but if it is the pc speaker then the following should disable it and stop the noise being produced. If it is the PC speaker and there is a soundcard installed a beep like this usually means that something is sending a random code that is being interpreted by the BIOS itself and creating the beep.

Disable Internal Speaker

As system beep is hardly used for anything you can safely disable it. Luckily it is really easy.

Go into device manager and click the 'view' menu, select 'show hidden devices' then expand the 'Non-Plug and Play drivers' section. Right click on 'Beep' and either disable or delete it.

Job done.

You can probably script this with devcon on machine startup.

This reg key may also work but it could just be for the citrix error that I found it under:

There's no scheduled task set up to run every hour on the machines are there?

I think you may have pointed me in the right direction Cache. I cannot believe that I didn't think of looking there! Anyway, there are hundreds of jobs scheduled to run every day on the hour. It appears that the beep is caused when processes cannot start or are already runnning. I just need to track down what put them there in the first place now. We have had a Conficker infection in recent months, so it may be down to this. I'll do some digging and post the results back up here.

Many thanks to all of you who offered advice. It's great to know that we can help each other out so speedily.

Dave.

Quick update:

It looks as though it's a remnant of the Conficker virus as discussed in this post.

Joy of joys, more clean up work to do!

I only suggested bios reset to factory defaults to elliminate the bios because if students had or have tampered with the settings then they may have done something to make it beep every hour ( was just a thought )

Other then that anti virus and anti spyware up to date and also disable any synch stuff through gpo

Also as above task scheduler - if nothing in there then I would be a bit stumped

as per above in bold
