PowerPC :: IBook Goes To Grey Screen - Won't Boot / How To Fix It

I have seen this talked about a fair bit, but i thought i'd start my own thread because it seems slightly different.

To start, when the computer was last running, the (what sounded like fan) started making a terrible noise, then stopped, and the computer turned off.

After that, when booting, it just goes to a grey/blue screen and sits there.

I have an iBook G4, 1064mhz, 256/30.

I dont know what model that makes it, but from the Mac website, I have tried to reset the PRAM to no avail. All of the methods listed do not seem to do anything on my ibook.

I tried using this link to reset the [URL]

I dont know which one is for my model, but i see no reset button under the keyboard, or on the case. There is a little tiny hole on the case beside the LCD???

I have tried the shift-ctrl-opt-power but it doesnt do anything.

As well, i did hold down the "option" button when booting, and it brings me to a screen which shows an image of a hard drive with a green "x"

I dont know if the green means good or the X means bad..

I have read that resetting PRAM and/or changing the resolution seem to help the problem, but I do not know how to do either.
