I have a HP laptop that has a weird problem that seems to be connected to the Windows 7 installer service. When programs are installed or uninstalled the audio system makes a weird, low-pitched repetitive noise. I have encountered this before, also on a HP machine and in that case it got so bad that it caused numerous BSODs. The machine I use has Beats audio but, as far as I can recall, the last one didn't. This problem began after downloading and installing some updates although I haven't been able to work which one it was. I bought this machine specifically for editing and creating audio so the problem is particularly annoying. I haven't been able to find anything similar on the internet and so not sure where to start.

Any help would be greatly appreciated.

You might try rolling back the audio driver in device manager.
If the update was a newer audio driver,that may have caused the problem.
Roll back the driver,then restart the computer and see if it clears up.
If it does,run windows update manually and see if there is an audio driver update
under optional updates.
If there is,hide that update so it doesn't install.
