DJM350 OR CDJ350 PROBLEM

Sound.. sound just stops.

I'm mixing in, nights going smashing, then bang, music just stops, VDJ platters stop moving, sound cuts & doesn't do anything.

I load up config change latency settings to absolutely anything and the sound returns magically again, (for 5-10 mins max) and then repeats and repeats and repeats

My setup as some of you might remember;

2 x Pioneer CDJ 350

Pioneer DJM350

Settings are External mixer Deck 1/First card Deck 2/Second card.

2 Sound cards - Pionner CDJ 1 & Pioneer CDJ 2.

My old laptop did this so i bought a brand new one which worked fine for approx one week, my laptop specs are;

Processors AMD A8-4500M APU with Radeon (tm)

Microsoft Windows 7 operating system

Dolby Digital Advanced Audio V2

6Gb RAM

1Tb (1000Gb) hard drive

USB 2.0, USB 3.0

720p HD webcam

2 Things i can say, i have Ableton Live on my laptop (not sure if this conflicts) & also i have my tracks on USB.

DPC latency checker never leaves green at all.
