Beeping

[crisbduck]

My girlfriends laptop beeps only when the optical drive is in
Its not been well since orange juice was spilt on it

Any ideas..?

edit
It appears it loves to beep randomly, mostly with the cd drive in.
sometimes loading windows and sometimes not..

Cheers for the info, might have to go for a clean since its pretty old!
I have read that continuous beeps are board failure or something
but also seen it could be keyboard being broken (have removed this, since it didn't work anyway)
