I've had a Mac or two for over twenty years but never seen this. When I turn on my 24" iMac ( 18 months old latest OS etc ) I get this constant very fast loud ( if the vol is on ) da da da da da just non stop until I click my profile to log in. Then I get in the password box non stop da da da da da with the bold black bullet points screaming across the password box where you type, if I were to just sit there it would go all day. In the end I hight light some of the bullets and press delete until I get rid of them all, then I can type my password.
I've had a few small problems since my son got addicted to World of WarCraft as the game seems to take up loads of memory etc. Could this be the cause and how can I cure it ?
Yes I know before anyone says " get the boy off the game".

Thanks

Very strange problem, would seem like a stuck-down key on the keyboard, does the same problem occur when you go into textedit? If so it will tell you which key is playing up, if this is the problem.
Could be a little out-there but you could try resetting the PRAM and NVRAM to see if that stops the problem.
Resetting your Mac's PRAM and NVRAM

Hope this helps

When trying to diagnose "strange sounds" it can be difficult i'm sure you can imagine without being able to hear it. Hopefully this will sort it though
Keep us posted

Ok, the resetting PRAM etc don't work or I can't get to work lol. Anyway I tried looking into the sticky Key idea. I re-started the iMac without the Keyboard connected. Fine up to the point when I plugged it in, all the noise started as per normal and then press any key on the keyboard it stops. No bullets screaming across the password box after when you log in. Maybe I need a new keyboard? The capital O won't work either unless you have caps lock on lol.

Text Edit ok.

It could be the "O" that is causing the problems... what keyboard have you got? Bluetooth or USB? And also does it have the numeric keys on it?

i think some ICs on the keyboard must have been damage. Pretty much, you need to do is buy a new one or borrow a keyboard if it is really your keyboard that has a problem.
