macbook will not boot up, apple sound goes, then it just shuts down

[direzz]

If there is anyone that can help me with this problem, that would be great!

My macbook was working fine yesterday, however, my whole system completely froze up on me. I tried everything to close down all windows, but nothing worked. So, I just powered down the whole machine. I waited a few minutes before powering it up again, and that is when a new problem occured.

The apple logo and start sound are shown/heard, but it sort of lags there for a few minutes and then just shuts down the whole machine. Does not get to login window.

What should I do?

Any help appreciated!

might sound like a stupid question, but is the battery dead? i presume not, but might be worth askin.

if not, try givin applecare a ring. i'm sure they'll tell you to reset the PRAM, as they do with every problem
