You might want to remove the extended RAM module and Airport, and reset the PMU and PRAM. This can sometimes make a difference. Beyond that, it's likely a flaky board, since bad hard drives rarely cause the computer to freeze up. Is the light on the AC adapter flickering or going between different colors by chance? Sometimes when the DC-in plug is bad it can be very sensitive, and a computer without working battery will die or freeze just from being bumped lightly. Good luck!

You're pushing that iBook pretty hard running 10.4 with 256MB RAM

That JUST meets minimum requirements.

If you have an almost full HD you could be running into memory swap issues. You need at least 6GIG hd free for VM and temp files.

I'd Max the RAM on that sucker... If you can't do that kill every background/startup app I didn't need (check what launches at login). I Would turn the computer off when not in use (clear Memory fragmentation).

Good Luck,

Any chance the freezing is related to the specific chess program you're using rather than overheating? Does the computer freeze when using other programs or doing other things? You mention "online," but I couldn't tell if that was from general surfing or if maybe your chess program is online.

== Is the RAM correct? == e.g. PC2700 (333MHz) DDR SDRAM and seated correctly?

Is the ram known to be good?

When you say "goes to 512MB" in system profiler=>memory does it see the new ram, or are you only looking at "about this mac"?
