At first it was only some of the time and quite quiet. Now its so loud it's getting annoying. Only when I move a window around the screen or something happens (dock scales, scrolling window etc).
Sounds like its building up to a blow out!
Should I be worried?

TiBook 667 OS 10.3.3

Where's the sound coming from?:

1. Speakers
2. Screen
3. Hard Drive
4. Fan

My guess is that the sound is coming from your hard drive, because I had a PC hard drive that would occasionally rev like a chainsaw. The unit never failed, but it was annoyingly loud.

Hi

The sound seemed to be coming from the back of the Pb but not the speakers. Definitley only when the screen scrolled or windows moved about. Not the HD as that would spin up at sepearate times and makes a different noise.
Pb has gone back to Apple with a broken motherboard anyway and is being replaced by Applecare witha new 1.33 Ghz AiBook so it's a moot point now. Maybe the funny noise was the board about to fry?

Not too pleased with the reliability of my TiBook overall but impressed that AC will send a brand new twice as fast machine for a two year old Mac!

My Pismo was replaced with a 12" PowerBook with one month left on AppleCare.

I will always buy AppleCare from this point on.

I totally agree.

Apple care is the most worth the money thing you can buy. Without it I would have had to fork out over £3000 worth of repairs to my PowerBook and STILL have a duff machine. As it is I'm up a brand new Mac and have saved heaps on repairs.

I'll have to ante-up for applecare, it seems.

Just so you know, the noise was coming from the inverter board (manages screen backlighting). Nothing to worry about.
