Alienware Aurora R4 won't boot

Yesterday morning I shut down my computer to install some windows updates (16 to be exact) and when I got up about 8 hours later it was on 11. So I went to work and came back home 12 hours later and my computer was off. So I figured it finished. Now when I press the power button the fans turn on, then idle down real low, the light on the side flash on for a millisecond(not even at full brightness) and turn off, and I have no connections to any USB, and my monitor just says "no signal". The white light on the power button remains on, the green light on the back by the power in, is solid green. When I open the hatch where you put a CD in those lights light up. I have no way to access the computers software. I tried removing power and holding down the power button to drain everything down, that didn't do anything. I tried putting in a CD that didn't work. It never beeps, no flashing light, just sits there spinning the fans, and the power light on. If anyone could give me an idea. HELPPP!
