m17 R2, locked up, screen froze

hi guys, my alienware m17 r2 crashed today. it locked up, screen froze. so i held down the power button until it shut off. i let it sit a minute, pushed power button, power button showed green,then went off, the keyboard rgb came on then went off, and the power button came on green again. it continualy does that. when it does that if you listen close you can hear the fan come on for a split second in time with the flashing.
