I got my alienware aurora R11. Today towards end of the day I shut down my computer through the windows icon. A couple hours later I turn it on but I get a screen with an error message and gives me the option to restart it or view what's wrong and I choose to restart. After I restart it, it shows the alienware logo on screen and the loading circle and then it freezes. I turn it off manually 3 times to see if it works then and nothing happens and now i don't even get the alienware logo, it's just a black screen. Please respond with any ideas of what's wrong/solutions asap. Thank you.
