I found that it also can come from the power that you are powering the
PC with.

My asterisk box emit's ticks especially on my ISDN phones, it didn't do
so before i moved it recently and the only difference i can see is the
powerbar. 

Originally i had the box on a APC powerbar with filters etc. Now it's on a plain one without filters.
Moving it back on a powerbar with filters solves the problem.

Kind regards,
