I broke my iBook G4 :(. (I took it almost all the way apart to replace a cracked screen frame) Does anyone have a suggestion?

Cold, it will boot up ok, and work for about 5-10 mintues and then freeze, completely (what was on the screen remains there, but the computer is completely unresponsive--the mouse doesn't even move, etc.)

If I force a reboot, it starts booting until it reaches the point where the screen turns from grey to blue and then freezes there. If I reboot again and again it will freeze at that same point. If I let it sit for a while (overnight), it will again boot all the way, only to freeze again after about 5 minutes.
:mad: :( :mad:

It passes the hardware tests (when booted to the hardware tests and in firewire mode it seems to work indefinitely). I thought it might be overheating--that I somehow messed up the contact between the heatsink and the processors, so I reseated the heatsink using fresh thermal compound--but this didn't help.

Or should I just give it up and sell it for parts on ebay?

Well, it certainly wouldn't hurt to ask the experts (that being Apple themselves) if they have a solution to your problems.

Still here.
I'm no Apple Genius..

...or electrical expert...

...by any means...

...but it kind of sounds like a short somewhere. Perhaps two logic boards coming in contact with one another, or something just not re-assembled properly.

Hell if I know, though.

Thanks for the suggestions. :)

A bent pin or something--why not? I've taken this apart several times, so I don't suppose once again would hurt, when I get some time.

*Sigh* The broken frame I was replacing was just a cosmetic problem, and now I've got a useless computer. *regret, regret, regret*

as soon as you press the power button, press and hold shift for about 1 minute. This happened to my old PM and i started it up like this, got all of my important files off it and then turned it off. It was a logic board problem but i cant be bothered to switch the logic board so i got an ibook for free to replace it.
