I have had an I7 alienware steam machine for about 7 months. It has intermittently been unable to boot up, and when this happens the alien head logo blinks yellow five times. I have tried power drains, and they work 50 percent of the time. I have reset the CMOS battery a few times, and that works for a couple of days, but then it happens again. I have left the power cord unplugged when I am not using it, and that worked for awhile, but the yellow lights keep showing up randomly. Should I just send it in? Or am I missing something?
