Is it a beep or a true knocking noise?

You should open the case and see if you can narrow it down as to where the noise is coming from. If it's the HDD, it may fizz soon. It could be a fan hitting a cable or even a cd drive. Only one way to find out. Don't touch anything when it's open and running. Just listen.

Sounds a bit like the floppy drive checking for a bootdisk.
