iBook G4 freezes after boot

[Cox Orange]

It sickens me that not one of these people suggested that you rum a memory test. I know it's too late because you're already probably broken the GPU by attempting a resolder but seriously. STOP WITH THIS OVERDRAMATIC ADVICE.

Jesus people.

There is a simple memory program called memtest, it will run tests on your memory and it will tell you if there are any failures. Often times, freezing is caused by bad RAM, not by bad ****ing graphics cards.

Here's a link if you get around to reviving the iBook:

Well, I clearly pointed out, that he could just use a bit of foil, which is reversable.

...All I'm saying is that I think maybe people here should start offering the simple solutions before "Herp Derp, GPU, Derp Derp" comes about.

Like Intell said "why not take into account the model's history of problems." GPU Freezing is very common with some ibooks and belongs to their history, which is, why I pointed at this.

Bad ram rarely causes freezing. Bad ram usually causes kernel panics and data corruption. Freezing can also be caused by corrupted data, a bad hard drive, overheating, or a faulty logicboard. But rarely bad ram.

not true i put a 1GB stick of Komputerbay RAM in my eMac and i got nothing but lockups hangups and freezes along with Boot failures and KPs

not true

Leo you might want to think a bit before you post.
"not true" also could be interpreted as a lie, so on your first day back from your unscheduled vacation do you really want to be calling forum veterans liars?

I thought about using the foil but I figured that maybe I should just learn the soldering and that it might be a more permanent solution. I didn't want to sell it and then have the person I sold it too asking for their money back because the foil moved inside and suddenly the iBook stopped working. Don't worry though this is just more troubleshooting experience with Macs which is fun for me anyways

Sorry Misinterpritation of words i did not mean it as a form of calling anyone a liar

I think a facepalm for myself is appropriate right about now lol. I really should've thought of checking for bad RAM for the few mins or so that I could try to keep the iBook running. Just before I soldered I tried to boot it up a number of times and it would simply send me into kernel panics at the apple logo. So what do you think should be my next step? Should I start seeing how much I'll be able to get for everything thats functional? I had a feeling if I didnt fix the GPU that maybe the Logic Board itself might have failed from age. I'm not sure.

If you screwed it up by soldering incorrectly you can use a solder sucker to restore it to its original state.

Ok, did you resolder the chip pointed to in the second post? because that's not the gpu. Yes it can cause the problem, but it's not the gpu (the gpu is one of the large BGA chips) before scrapping the board check your soldering.

As for ram causing freezing, yes, in my experience it does, and before Intell says i don't know what i'm talking about and that it only ever causes kp's, i have had macs with bad ram that freeze on one boot and kp on another.
I am not proclaiming to be a expert, just someone with quite a bit of experience, and from that i have had some freeze, some kp, and some do both.

Yea you're right that's not the GPU. The GPU is closer to the CPU and connected to the heat pipe/heatsink assembly on the upper part of the case. Anyway, I repaired my iBook with that method years ago, and my memory was telling me that that chip is connected to the GPU somehow...can't remember.

Thanks!

Thanks for all of your helpful advice! Unfortunately I'm going to have to part it out so I can continue moving forward. Don't worry though if I have trouble when I get my hands on my next iBook or Powerbook you'll see more posts again.
