Macbook fails to startup

[justjuice]

Howdy! : D
I have a macbook and just about 2 hours ago it froze.
So I restarted it.
But it wouldn't restart.
It turned off but won't turn on.
When I go to turn it on I can hear it kind of start.
Like I can tell something is running, but its really quiet and usually its louder when it starts up.
The screen doesn't turn on at all.
And when I turn it off by holding the button down there's a little noise like 'pyu'
Its an early 2007 model and its no longer under apple care.
I'm not sure what I should do, I've already tried the power management restart.
And that didn't work.
Help would be greatly appreciated ! : D

Oh no need to worry now a friend told me to do ctrl+cmd+power button and it worked! : D

Control command power? I think that's for iBooks.

A PRAM reset is command-option-p-r at startup until it chimes twice. A SMC reset is shutting down, unplugging the magsafe, taking out the battery, and holding down the power button for 5 seconds. The last thing is starting up in safe mode by holding down shift and logging in with your password. It runs a lot of normal maintenance.
