Ok so I have a Lenovo y50 with the Intel i7 4700hq and the nvidia gtx 860m no touch screen. It worked for a while and then it did the "checking media," "edit network 0 for IPv4 boot failed" and same for IPv6. I went and got it "fixed" then it ended up doing the same thing. Some times it would come on and now it won't boot into windows or just gives me the IPv4 error. I have lost hope in it and now I want to sell it to get money for a desktop. What should I do? I think it might be the hard drive (because it's a know problem)but I'm not sure. What can I do to get the most money out of it?
