i've been noticing a weird noise when i'm playing music through my pc speakers. it sounds like i'm playing a really shitty cassette tape through it. i have a wireless router sitting about 4' away from my pc, could that be causing that? my speakers are klipsch pro media 2.1. i'm still using the factory speaker wires but i wouldn't think those would be causing the problem? i'm going to make some new cables tomorrow for it since the factory ones suck. anybody have any ideas what might be causing this?
