so sorry sounds like you need a genius at apple to look at it. Good luck!!

Does it chime? Get a blinking folder? or just nothing?

no warranty so probably cant get a genius to look at it. JerryButler when I push power in wont start I just heard horrible fan sounds

Like fans at full speed???

I think so. I have never heard it that loud and bad before

That does sound like logic board.. if you have the factory disk, put it in and hold C - see if it starts up
