My HP pavilion laptop is getting pretty old and the speakers no longer work properly. So I've disabled all audio devices, including disabling the light-touch volume controls at boot-up.

The one sound still here that I can't get rid of is the alert beep whenever there's an error. It's annoying at the best of times, but when your laptop has no other sounds at all it's intensely irritating!

Nothing I change in the windows settings or in the BIOS seems to have any effect. Any ideas how to switch them off?

The motherboard beeper? It's always annoying. I try not to plug it in.

Open a cmd instance, and type net stop beep. If that stops the beeps, then go to Device Manager (devmgmt.msc), find System Speaker, and check the Show Hidden Devices box. Find beep, and disable it.
