Pioneer Wireless Ok

static noises comeing from my suround sound?
ok so this is the problem, i have a pioneer suround sound system, a 200 watt self contained sub, a 50″ DLP tv, xbox, snes, nes, bluray.. i notice more when im on my computer that is a compaq desktop.. connected VGA. i get random surges of static sounding interference. lasting different amounts of time, some times just 3 seconds others up to 10 or 12. i got a wireless keyboard and mouse and when the static stars my keyboard and mouse wont work till the static stops. ALSO i get horizontal lines in my tv when the static happens. i have checked the ground outside, checked the ground at the power pole ( i work on powerlines) checked the neutral, i even tried the computer on my friends tv, he had no problem… any ideas what it could be and how to fix it?
the cable to your computer might play a part in that
