Aurora R?, not turning on

I don't know a lot about computers, but i've had my Alienware aurora for over a year with no problems, but today I was playing CSGO, and the computer totally froze, so I force shut it down, and now when I try and turn it back on the power button flashes orange, then blue, and it seems to turn on, but then stops, and repeats the cycle indefinitely. Please help me I have no idea what i'm doing.
