I would return it and buy a new one, especially if they are going to replace your motherboard, basically taking apart your new pc entirely. Then what if they tell you the spare motherboard is out of stock and you have to wait? All for 200 dollars? If I were you I would return it, then buy a new one. True, it's hard to find another 17" with the same spec sheet. Have you ever tried a Razer Blade 17? One of my colleagues had one at work the other week, it looked amazing.
After using the 9710 for about 20 minutes, the next morning it will not boot past Windows logo and I get continuous 2 amber followed by 8 white lights. I have Pro support. Tech support indicates it's most likely a faulty Mobo. Would you get them to replace the mobo (onsite I assume as I have NBD repair service), send it back and get a new one (another long wait plus same configuration would cost over $200 more now) or    buy something else? I just really want a 17" glossy UHD screen and can't find any other brands that feature one. Thanks in advance! 
9710 Essentially DOA. What would you do?
