This system appears to be refurbished out of an office.  My problem is I bought this to use with and DJ controller but it doesn't recognize or can find a sound card.  It should be a simple fix but I can't seem to communicate with customer service.  I've tried the e-mail route and tried phone calls but not able to reach or speak to anyone.  I got some returned emails that appear to be computer-generated.  I should have dealt with this earlier when I could still send it back.  This has been my experience lately with electronics I have purchased through Amazon.  Never again.  If it's something that may require technical support I won't be getting it through Amazon.  I'll have to see if I can trade this in on something that actually works at a computer shop.  I have a feeling they're going to tell me it's not worht $100.  Oh well lesson learned.
