Please Help Me: Alienware Aurora 7500 Failing to Enter Boot Process

I'm looking for some computer savyness:

I have a Alienware Aurora 7500-R4 , its a couple years old now, and its having a little trouble. I would list the specs but it won't turn on.

When I hit the power button, I hear the fans spin, and it sounds like everything is good, but then nothing happens.

The monitor remains inactive. From looking into the case, a quick glance of mine seemed to see that all the cables were attached and everything looked normal

I don't hear any Bios-error beep noises, I just hit the power button, the case, and led's light up, but then it stays that way. Monitor just stays inactive.
Does anyone have any suggestions or ideas to what might be causing this? Thanks a lot for your ideas.

If the ram thing fails, it could be the power supply not managing to give enough output.

you havent been messing around inside it have you? like taking it apart? if that is the case, do see if you missed something.
