So I received my XPS 15 on Wednesday, and only a couple hours after getting it and installing Windows 8, it stopped being able to recognize the hard drive. I was finally able to reinstall Windows by changing the SATA. It seemed to work fine, but rebooting caused it to repeat its previous error, and now changing the SATA isn't doing anything. The BSOD comes and goes so fast that I can't actually read it, nor am I presented with the automatic repair and option to go to the command prompt, as I was before.
Is there anything I can do besides send it in?
