Reply to High cpu usage... help!!

Hi, just bought myself a Stanton scs3 system running TPro using a numark DJio soundcard.

AMD Turion X2 Processor 4gb Ram windows vista home premium 32bit op system 2.0 ghz.

I'm going into the red quite often-sound glitches, then laptop crashes! I have played with the latency, but no joy, tried different usb ports. I've updated all drivers turned off Norton anti virus and internet.
I have also tried a numark omni control this also does the same high cpu etc.. All hardware is brand new, all software is current. I am not a computer buff and really don't know what to do or where to start. Plus i've got a gig this coming Saturday..24/02/2011 and am getting very worried.


(RE format the hardrive???)

Please remember i am a beginner, any help would be much appreciated.

Thanks Rastey
