Freezing, Panics, and a Logic Board error

Okay, I have a PowerMac G4 Gigabit Ethernet, and it's been crashing, giving me kernal panics, and today, toasted my main hard drive. It's running on:
1.2GHz Sonnet G4 upgrade
1.5GB Ram (2x256 and 2x512)
Radeon 9800 128MB
2x20GB hard drives RAID striped
18GB spare
combo drive
2x120GB external firewire drives
I can give more details if needed, but basically, if I watch TV resolution video with VLC media player it will crash after 25 minutes or so,if I run the iTunes visualizer for 15 mintues it will crash, if I play World of Warcraft for about 30 minutes it will crash, actually, if I run any graphically intensive game it crashes. Then today I ran the Apple update for the JSE (or whatever) and 10.4.6, then when I rebooted, it gave me a kernal panic, where the first line said something about not having the driver for "Powermac G4 3,3". Then I run Apple hardware test 1.0.1, I ran that 5 times, and the first time, I got the error "scc /3/7" every time after that I got "scc /1/5" all on the logic board, and it wouldn't test pass that. I do have the machine running but since I left my system disc at my parents', I'm booting it from another machine in target disk mode that has 10.3.9 (option-boot saved my butt, kinda). Last but not least, I cannot access my main drive (the 2x20GB RAID), and I'm hoping someone has a way to get to it, but every time I start, it tells me that I've connected a disk that is not recognized my Mac OS. If the drives are gone, I'll have to deal with it, but I can't have my machine freezing on me like this, and any help is much appreciated
Gigabit Ethernet Powermac G4 Mac OS X (10.3.9)

Well after 5 tests and every time having the logic board fail I am willing to bet that the logic board IS the probable cause.
What I would do is disconnect all the drives (minus the x2 20gig raid) and get the data off each one. If that other machine you are booting up in targeted disk mode has at least 1 open ATA66 slot free then you can simply change the jumper settings on each drive and get the data off. This will also give you a chance to test and verify each disk.
If the other Mac you are using targeted disk mode on is a laptop then you could go the slower rout of taking turns with making each drive the master drive on the internal ATA66 buss that your machine started with. That way each time you start up with targeted disk mode you can get the data off that drive.
Once all your data is off I would consider the cost for a replacement board (probably $3-500 is my guess) vs the cost of getting a new machine or simply a used newer machine (like a dual 1.2Ghz G4 or something allong those lines). The drives will work in the newer machine so there would be no costs in getting new drives compatible with the system. That is my thoughts.

AHT finds logic board error, but computer working fine

I ran the Apple Hardware Test to see the profile for my RAM, but 7 seconds into the test it stopped and reported a logic board error.
1. But my computer is working fine. If anyone has experience with this, I'll gladly take your advice. Do I ignore this error at my own risk? Or should I get it looked at now in case it's an early warning of something that can get worse? For the real Apple tech experts, here's the error code: 2I2C/1/1: 0x00000092.
Eleven months ago, I had to get a new power supply installed. It was covered under the extended warranty for power issues with iMac G5s. As I've indicated, it's been working fine since then.
2. Once AHT finds an error, it won't continue testing the remaining components. Does anyone know of a way to "force" the AHT to skip the logic board test and go on to test the other hardware items?
Thanks all.

Michael, pray tell, where does one find the published list of codes you refer to? I searched the whole internet (or so it seemed like it) looking for a resource like that. Are you an AASP?
Even my experienced Apple technician and his AASP contacts didn't realize that my error code relates to the European Union. (And, BTW, I'm in Canada and I purchased my iMac from a store in Canada.) You have solved a mystery!
The strange thing is that when I phoned Apple Tech Support and asked to speak to a product specialist, even they told me that the code means "logic board needs replacement." When I asked to speak to a higher dept., I was connected to Customer Relations (very nice, professional fellow answered). When I explained that this G5 iMac has been problematic for me (failure after 7 mos. of ownership, power supply failure after 3 yrs, etc.) he offered me $100.00 off a new iMac ($125.00 in Canada), which I accepted.
I did use TechTool Pro to check the computer. It found no problems. Four months later and it's still going strong. I don't know whether to be upset with Apple for not bothering to look up the code, or whether I should look at this as a blessing in disguise (how else would I have received $125.00 off a new iMac? And now, my father gets a G5 that I can confidently say is in good working order). And it's strange that my local tech's AASP friends weren't any wiser. Aren't AASPs privy to this error code info? A mystery indeed...

My mac book pro crashed and the logic board died. They said that i could get the hard drive out and it should have all my files on it. How do i get them off and put them on my new computer?

Do you mean a case for the external hard drive? See here. Hope this may be helpful to you.

My MacBook pro has been freezing up and giving me an error message.

My MacBook pro has been freezing up and giving me an error message. I did the disk repair and reboot in safe mode for it, and then I restarted it in regular mode. Still crashed and told me to hold down the power button to restart. It seems to only do it while I'm using the Internet. Any suggestions?

Are i5 and i7 logic boards in the 27" imacs the same? i

Are i5 and i7 logic boards in the 27" imacs the same? i know that the i5 uses the 661-5429 p/n and the i7 the 661-5428 p/n but are they interchangeable?
Do they have the same sockets?
Thanks.

Perhaps the best news to come out of Intel's new line of i5 and i7 processors is introduction of a single socket for all Sandy Bridge Core i3/i5/i7 processors...
For now, however, the Sandy Bridge processors all use the LGA 1155 socket. In case you're wondering, this socket is not backwards compatible with previous LGA1156 processors - don't try it unless you like junking your hardware.

400 and 500 Logic Boards

Are the 400Mhz and 500Mhz logic boards interchangeable? Can I put a 500Mhz logic board in a powerbook originally fitted with a 400Mhz board?

Yes, they are interchangeable. The only problem I can think of that you might encounter is that the installer DVD or CDs originally shipped with the 400MHz Powerbook may no longer be willing to install anything on it after the faster board is installed. If you have no further use for that disc, the problem won't arise, and even if you do, it may turn out to work just fine.

Logic board: error code 2ROM/1/2:0X12 i try to reinstall tiger for our G5

Need help:
logic board error: error code 2Rom/1/2:0x12 while doing the hardware test for G5 before reinstalling Tiger.
please need help
thanks.

AHT isn't always dead on this is true.
Just out of curiosity, what are your symptoms? I am guessing that the start-up drive doesn't work if you put it into the 2nd bay?

I have been trying to get my ibook g4 fixed from apple for 6 years now. my ram doesnt work and the logic board is f'd up aswell... i know 12 people that have had the same issue. 4 of them got there ibooks replaced. anyone know what to do?

i have been trying to get my ibook g4 fixed from apple for 6 years now. my ram doesnt work and the logic board is f'd up aswell... i know 12 people that have had the same issue. 4 of them got there ibooks replaced. anyone know what to do? all 4 ibooks were replaced outside warranty, why wont apple help me...

Apple supports most of their computer products for a 7 year period, could be that your IBook is well past any kind of help.Secondly parts are no longer being made for this machine and never will be again. Finally I find it hard to believe that nothing has been done with this for 6 years.Have you documented the reasons why you were turned down for repairs ? were the replaced Ibooks within a couple of months of warranty expiration? What model is your IBook ? At least if we knew what the model #, some of the more techy types could find out if there were any repair programs for your model.
Seems odd that you'd hang on to a non-working IBook for that long.

Kernel Panic Log, New logic board, new ram....same problem.

I have had continuous problems with my computer. First Apple said it was the Ram...replaced...same thing still happening. So they said oh, must be the logic board...replaced...still happening. Glad I have apple care or i might be more angry. ha.
Basically not sure what is going on.. i have tried to figure out if its a software issue. But it happens at different times. It did seem related to internet use. But turned all that off and worked in photoshop and it happened anyway.
Love the gray screen with all the languages telling me my computer is whack and wants to restart, they must know how i like to brush up on my foreign languages...but i feel that i have learned all i can at this point.
I am copy and pasting my panic log, so anyone who might understand what it is saying. Please shed some light on what i can try to do now.
I use airport to connect to internet. FYI.
Here it is (its long, happens frequently after all)

Cheers - I've run Rember a few times and it hasn't come up with any errors, but I've heard it's not a 100% accurate test. Looks like that's the only thing left it could be!

Many kernel panics, possible dead logic board?

I hope someone can help my diagnose my recently quirky iMac G4 1 ghz 17 in flat panel. I currently have a 250 G Seagate hard drive, 1 G memory. It's running Tiger 10.4.11...or attempting to run it.
This computer ran beautifully until several weeks ago when I foolishly attempted to upgrade to Leopard. Only about a third of Leopard got installed when the system froze and crashed. I managed to access the hard drive and did a complete wipe and install of good old Tiger, upgraded to 10.4.10 which ran without a glitch in the past.
However, even after this clean reinstall I continued to get freezes and kernel panics. I repaired all permissions carefully after each upgrade and I ran Disk Utility with no problems detected and no repairs needing to be done. I tried to run Disk Warrior to double check but continued to have system freezes and kernel panics while running Disk Warrior!! The panics were/are intermittent. The computer behaves fine until I've used it for a few hours, then crashes, usually while I am in Safari or iTunes, but occasionally I will get a panic at start up.
I have replaced the hard drive with a brand new one as it was still under warranty. I tested the memory and determined by process of elimination that the stick of RAM on the logic board was not functioning. I replaced that.
So, I have a new hard drive and functional memory and tried a Tiger fresh reinstall yet again today. The system continues to crash episodically...used the computer for a few hours this am before I got a kernel panic. This afternoon it resuscitated itself enough to let me put upgrade 10.4.5 on it and crashed in the middle of the upgrade! Bear in mind the machine's run all these upgrades and functioned fine in the past.
I think I obviously have a hardware problem and since I've recently replaced the hard drive and both memory modules as well as done a fresh reinstall of the OS version this iMac used to run perfectly, I'm thinking I have a logic board issue.
Any opinions or suggestions on how I might get these issues worked out would be very much appreciated!

Thanks for responding. Yes, I've already followed all those suggestions to the letter. Unfortunately I do not have the original Apple Hardware Test disc that came with this computer. I have oredered a copy of Tech Tool Pro and plan to run it but it has yet to arrive.
I let the computer rest overnight and it booted right up and so far no freezes or panics, I've been using it about a half-hour.
Of note, in the kernel panic log folder it says,

My MacBook Pro randomly freezing ever since new logic board?

My mid 2012 MacBook Pro 13" keeps ok randomly freezing ever since I've had a new logic board fitted after my macbook needed a new one (it was fixed through stormfront which is an official apple retailer). It will just freeze, won't be able to move the mouse or anything, and sometimes when I turn it off by holding down the power button, I can most of the time hear a click, but not everytime. Sometimes it freezes when starting up, sometimes it lasts a while before freezing, but recently it's been more like every 5-10 minutes. Can anyone help me as to why this is happening and what the problem may be? I'm running OS X Mavericks. Thankyou.

If You are european then even if youtube out of warrenty then in most countries, its sos that if any element was repaird under warrenty its warrenty is counting from the moment it was repaired. If you are us You have to read warrenty laws.

Mouse freezes after I fixed logic board/graphics problem. Help!!!!

Hi,
I'm sick ofthis stupid laptop!!Aghghghggh
I recently had a problem with my 14' ibook with the display going out. I thought that if I put a monitor adapter on it, it would display, but it still didn't.
Now, I put a search through and found out from Ronda Wilsons posts that you could put a 1 mm to 1.5 mm square on the raised square under the lower case to bring the graphics back. It was a success!!! My computer loaded fine!!!
BUUUUUUUUTTTTTTT, now the darn thing's mouse freezes after about two to five minutes of being on. So when I start it, I can click on a couple folders and then the mouse arrow just sits there.. Then I have to press the power button inorder to restart it. Same thing happens for the fifth time. I also installed a replacement modem for the 14' as well as the sticky square for the logic board problem. Both works fine.
Could my mouse be affected by the change and how do I fix it?

Have you tried resetting the PMU?
The PMU (Power Management Unit) controls trackpad function, so resetting it often helps when the trackpad isn't working (or isn't working right).

Logic Board Error-No Firwire

I'm almost afraid to ask this question, but I just did a hardware test on my MDD G4 Dual Gig because I lost my firewire devices today. The Logic Board test revealed an error code fire 3/20. Is something fried? Can I replace it myself? This couldn't happen at a worse time because I'm editing video!!
HELP oh wise Mac people.

Hello! Sometimes the firewire ports "trip" out. Try shutting down and unplugging everything for about 30 minutes. Then restart and see if they have reset. Tom

Grey Screen at start-up - Troubleshoot harddrive and/or logic board?

Hi everyone. Sorry for the lengthy post, but hopefully you can help me - I've spent a lot of time on the boards already, but hoped you could clarify some things.
The problem is my Powerbook will not get past the grey screen at start-up. It will not boot off the 10.5 install disk and I can't eject the install disk to run the hardware test disk. Removing 3rd party ram, resetting PRAM, NVRAM, attempting to boot in 'safe' mode haven't helped. The harddrive is softly clicking/searching.
So some questions:
1) Is it possible that an interrupted time machine backup will bork the drive to the point where it wont boot? (See back-story below). I wouldn't have thought so, but prove me wrong.
2) Should I be able to boot from the install disk if the harddrive is stuffed?
3) If it is hardware, it's either the logic board or the drive. Is there any way to determine what it is (eg: is it possible to do a remote hardware test?)
Edit: Just tried mounting the drive in target disk mode using an iBook, but it wouldn't mount. Powerbook displays a black screen.
Oh, and I should point out that this is well out of warranty and any fixes would have to be cheap : ). Basically I need to determine if it's the drive or the logic board, preferably without having to buy and install a new drive when it may not be the problem.
Any help or advice would be appreciated.
Cheers
- Ben
Here's the back story if it's any help; recently upgraded to 10.5, created a base install disk image of all installed and registered apps (in the event that my drive failed). Copied data etc from the previous system over. It ran fine for a few days. This morning I ran time machine for the first time, left the computer for a while, came back and the screen was black (as if it was just displaying black, as opposed to off). Thinking it was just a display issue (which I've seen before), I put the system to sleep (power button, then 's'), woke it up again; still black. So I forced a shut down (wouldn't allow me to do a normal shut down, because dialogue boxes must have been preventing it) and on boot I got the grey screen.
-------

Hi Ben W. I don't have a good answer for you, but based on your information and what you've done, I think I would try starting the machine after disconnecting the harddrive. That requires taking the top off first, for which instructions are on ifixit.com.
I can conjecture that a blown HD is preventing normal operation, perhaps sucking the power down, disrupting the optical drive, etc. This is purely conjecture, but costs you nothing but your time. If this turns out to be the case, I figure the optical drive should start responding again (hold C key during reboot, etc).

How can I tell if my motherboard and/or logic board is fried?

Good evening all, I was just wondering if anybody can tell me the way to find out if my old power mac mobo is fried, or weather it's the logic board or the power supply. When I try to boot it up there is no start up chime, there is no white power on light and the red light doesn't even come on. It's one of those bad liquid cooled models but it hasn't leaked. I really don't have the luxury of spending a lot of money just to have someone diagnose the thing for me. I would be willing to replace the power supply for the price that was quoted to me off hand from an apple tech, but the person on the phone wouldn't let me talk to the tech so he wouldn't answer my ? and I despise the genius bar kids who don't seem to know the hard core techie stuff and I tend to talk circles around them. Sorry if there is already a post on this (I searched but came up with nothing) or if this is a dumb or fruitless effort on my part but no clear answers yet found in the magical internet.
Cheers and thanks in advance for your responses!

Can you count the beeps or flashes of the Power Button?
1 beep = no RAM installed
2 beeps = incompatible RAM types
3 beeps = no good banks
4 beeps = no good boot images in the boot ROM (and/or bad sys config block)
5 beeps = processor is not usable
In addition to the beeps, on some computers the power LED will flash a corresponding number of times plus one. The LED will repeat the sequence after approximately a 5-second pause. The tones are only played once.
Note: In this case, a flash is considered to be 1/4 second or 250 ms or greater in length.
http://support.apple.com/kb/HT1547
Power Mac G5 (Late 2005) computers have six or seven built-in diagnostic LEDs on the main logic board that can help Apple Authorized Service Providers (AASPs) troubleshoot certain issues. These LEDs are located to the left of the top bank of DIMM connectors (where your computer's RAM is installed):
