i've actually discovered the source of the problem with some detective work.
i discovered that when this noise was happening the green light on our floopy drive was on.
so after disabling the floopy drive the noise stopped. so i assume it was the floopy drive.

now the noise is completely gone and we dont use the floopy drive anyway..
thanks for you help but!!
