I just bought the NXP-301, and the lights stay on for about 30 seconds then the flicker off for about 1 second up to 10 seconds, and then do it randomly every 3-30 seconds...I know this model has sound activation lights, but its not set to do sound activation. They are set to just on. Any help on this subject is extremely appreciated. Also my power supply is a 450W OCZ Modstream, so I dont believe it is a PSU problem..Thanks
