I ordered this product for my son for Christmas and it doesn’t work. The graphics cartridge is bad in it. I have contacted the manufacturer and they don’t answer the phone. I am in the works with Amazon right now in trying to get another one sent or a refund and they are making me contact the manufacturer. I really don’t know what to do at this point. My son is upset that his Christmas gift doesn’t work and I can’t spend another 750 dollars on another computer. I’m hoping I can either get a refund to get him another or I can get a new one sent.
