My iMac plays a loud "chord" when starting up.

I tried all means to get rid of it: I turned off the sound (from the keyboard), I diasbled all alerts (from System Preferences) and finally I plugged a pair of earbuds in the earphone jack and redirected all audio to them.

Nothing worked and I am still "greeted" by the same sound every day and every night during the power-on sequence.


Can anyone please help?

iMac, Mac OS X (10.7.5)
