Hello,

I have really annoying problem with my system.As first i want to introduce you my gear:
audio4dj scratch duo , technics 1210mk2 x2 , got two mixers Vestax PCV 180 and DJM800, CDJ1000mk3 x2.
The problems appear whatever mixer or cdj / turntable i use.
In a middle of playing i get some nasty cracking / static noise , like when you have problems with power. I contacted service for DJ stuff , took my dj gear to them , (both mixers , and turntables and CDJS) and they told me everything is ok , there is no problem with ground wire etc.)
The problems appear like every 15 minutes or less , it lasts for few seconds and its really annoying to people in clubs that i play. It makes me feel really bad , and i try to avoid using my scratch system cuz of that.
I checked my pc with antivirus and cleaner stuffs , everything works fine.
My laptop is ASUS x71vn pro . Windows 7. I attached you a note with DXDIAG if you need to see drivers and stuff.
Please help me as soon as possible.

Please help

I didn't find the right solution from the internet.
