Booting problem

[clevin]

5 weeks old white MacBook 1.83GHz
this afternoon, when i tried to start it
1. i pressed power button
2. I heard "chim" sound.
the white apple screen did not show up, and stay that way

Later, I managed to solve the problem by holding opt+cmd+p+r after pressing power. And so far, after several shut-down-start-again processes (twice), it looks ok.

My question is:
what caused the problem?
BTW: I didn't add any RAM.

install any new programs or updates?

see, thats what puzzles me, i didn't install anything today. there is no hardware/software alteration of any kind, it just weird.

I hope this is not a hardware problem, This is kind of frustrating, switch to Mac is because of its reputation, but looking around, this macbook keeps me worrisome for sometime now, all the news about discoloration, random shutdown, now I got this, i wonder if apple's quality is getting worse now.

I know some MacBooks have been having similar problems. I'd talk to Apple about it, if only to get a record of the fact you've had problems.
