I cannot filter out noise from my computer, I have tried two different types of X10 noise filters. My X10 does not respond at all when my computer is plugged in, even with the computer plugged into the X10 filter.

I used the X-10 FilterLinc 10-Amp Plug-In X10 Noise Filter (didn't work)

I have even tried two X10 filters back to back (double), still no luck

I need a better filter, does anyone have any ideas?
