(Redirected) Alienware x51 R2 will not boot correctly

My alienware x51 r2 will not boot correctly. I've had the computer since around christmas last year. Everytime I try to start it up the fan starts and the light comes on but then it immediately turns off and does this over and over again. I unplugged it and plugged it back in and I was able to log on but the computer immediately froze on the desktop (windows 10). Once I turned it off, the boot process started again but just keeps turning on and off over and over. Any solutions?
