Powermac G5 freeze REASONS

Everyone using Powermac Dual or Single may suffer from crashes or freeze suddenly. I would like to draw everyone attention that the cause was merely by USB port behind which we usually attach with Apple Pro Keyboard.
I suffered this for at least 5 months but my Powermac have not join Apple Care after warranty expired and I was headached all along coz' the crash and freeze is abnormal!!! I ran all test using utility but none error found, also doubt if my Kingston RAM incompatible with Powermac and tried many resetting PMU but none can't solve the problem really. So until today I plug out all USB device including APPLE keyboard from behind and let the powermac rendering IDVD and playing MP4 movie at the same times and found out without anythg attached, the system is very stable and seldom heard the crazy noisy fan spinning which we all heard after it freeze or crash.
Then I tried to use the front USB port for keyboard ( with anther USB 2.0 hub with power), then it solved entirely. Coz' I bought a Microsoft notebook wireless mouse attached on Apple keyboard after my mighty mouse got out of order 3 months ago and suddenly one day after it freeze several time and I reboot the PC, the wireless mouse seems very sluggish and I need to use extension cable to connect the USB dongle almost touch with the mouse then it work and I returned the wiremouse to dealer and they found that the dongle was so-how got burnt by unknown reasons. So today I just followed this clue to look out again and what a coincidenc to find an old thread posted in 2005 by someone who pointed the same thgs about the USB port behind the tower connecting Apple keyboard would cause Powermac freeze.
So anyone suffer form this can try out if this way work , if so, plse every one send a complain to Apple.

PowerMac G5 Freezing

Hey everyone. I've been having some trouble with a Mac in my possession and was hoping for some insight.
Apparently from the first few weeks of use this computer has experienced random lock-ups when running basic programs (Safari, Terminal, iTunes, etc.). It could be sitting idle for a few hours and then freeze, or within the first 2-3 minutes of using Safari, or within a song in iTunes...you get the idea. So I ran through all the regular stuff - checked for and updated system software, looked for firmware updates, and watched the 'top' command from time to time. None of these cleared up the problem. So then I tried a re-install of the OS (originally 10.3.9). This also proved fruitless, as the computer resumed stalling in all the previously mentioned ways. Next, I tried wiping the drive to all zeros and installing OSX 10.4. Once the OS was up, I ran the Software Updater to get all the latest patches. I ran the system for a few minutes in various programs before experiencing yet another freeze. So now I got down to the hardware...
First, I tried running the Apple Hardware Test disc that came with the Mac. I ran a short and long test, both of which passed. I then ran the Long Test on loop for 12.5 hours (12 loops). All passed without incident. The machine stayed running the entire time, never once crashing. Next, I removed the hard drive and zeroed it using a Seagate utility, hoping it was something the Apple software did. Reinstalled, patched...freeze. So I tried a different hard drive in its place. Zeroed it, installed 10.4, patched. Froze again. At this point, I got a bit frustrated. So, I attempted running a Linux PPC LiveCD on the machine. To my surprise, it ran like a champ. I had at least 6 programs running, playing music, browsing the web, running a game, etc. No freezes, no hiccups for 4 hours of use. Booted back into 10.4, and froze within minutes.
So finally, I tried the memory modules. I pulled all four, put them into my PC and ran memtest86. I let this run for about 3.5 hours. No errors reported. So I figured I'd try only plugging so many modules back in, leaving one slot empty. I tried this with all four, with no luck. (Interestingly, when I tried removing the Slot 0 DIMM and starting, the machines power light blinked three times repeatedly. Couldn't get to OSX until I replaced em all and rebooted.)
So, I'm not sure this is a hardware problem, seeing as how Linux PPC ran fine. Although I'm not sure it's not either. Maybe Linux didn't hit a bad segment of memory, processor, etc. I know that probably no one has seen a situation like this, but I've been all over these forums for the past week looking for answers, and coming up short.
Any help you all could provide would be GREATLY appreciated.
Thanks again!
PowerMac G5 1.6GHz Mac OS X (10.4.9) 1.25 GB RAM, 80GB HDD

So I've tried running the AppleJack utils. It completes and asks to have the machine restarted. Upon getting back into OS X I find that the freeze phenomenon is still present. I was hoping that I could pull the memory modules from my PC and try them in the G5, however I've run into a problem there too. I have 2 1GB DDR400 memory modules (matched) in my PC. The Mac uses 4 modules, 2 512MB DDR333 modules and 2 128MB DDR333 modules. They appear to be set up for dual channel operation. I tried removing all 4 DIMMs from the Mac and placing 1 of my 1GB pieces in Slot 0 of the DDR bank. Upon bootup, the power indicator blinks once with a 1-2 delay before a similar blink. Does the machine require a dual channel setup? Is it complaining because the memory config. has changed? Will the Mac's logic board not accept the DDR400 (i.e. not scale back the memory to operate at DDR333)?
This is one of the last ideas I have for this machine. I'm afraid that soon I may have to have someone from Apple diagnose it to find out if it's a logic board / processor issue. In that instance, how has everyone's experience been with them? Do the techs know whats going on, or is it hit-or-miss?
Thanks again everyone. I appreciate the help.

PowerMac G5 freezes shortly after startup without fail

Hi,
I have a PowerMac G5 running Tiger and am having an issue with it freezing.
The whole system will freeze, including the cursor, about a minute after startup. Sometimes it happens during startup and sometimes its longer than a minute, but it always happens.
I haven't installed anything new lately and I'm not sure what would have caused this.
I was able to boot from the install CD but unable to run it because the system freezes before I can do anything. I tried booting while holding down Command+S and was able to boot, but still have the freezing issue.
Anyone have suggestions on what to try next? Please let me know if you need any particular information to help determine the cause.
Thank you!
Dan

PowerMac MDD freeze seconds after start

Hello,
I have problems with my PowerMac MDD since months, I tried lot of things, but now it's getting worse and worse.
It used to freeze without warning (mostly with Safari), I tried to change to Fireforks with no luck.
It then freezed more often, I take back the memory chip that the previous owner added, I disconnected the mouse from the keyboard, added a new generic usb mouse directly in the USB port, nothing.
Now, after two kernel panics, my Mac freeze slowly within seconds, minutes eventually when I login with a new user account, even if I don't launch anything, and with ethernet unplugged (no internet).
The last time, they where lines of tiny dots visible in the logging window, and in finders window.
The processor has been changed if it is important, it's a Gigadesign G-celerator 2xPPC G4 1,42GHz.
I suspect a hardware problem, but I can't imagine what is wrong...
Thanks for any advise,

Powermac G5 - Freeze after startup, tried everything

Hi, I have a Powermac G5 Dual, its a few years old and I previously had an issue with the screen (line patterns and lank screen) which was serviced and in the end they replaced my ATI Radeon graphis card which seemed to do the trick.
Since updating to Leopard OS 10.5.6 whenever I start my computer up I get the chime etc and i can log in on my password screen, but straight on the desktop the mouse keyboard everything freezes and occasionally this is followed or preceeded with a blank screen. The fans then Rev up pretty loud. Additonally i do not have any 3rd party RAM
Ive tried a lot of stuff such as
resetting PRAM
trying to boot in safe mode (gets stuck on white screen with apple logo, doesnt boot)
running fsck -fy
Can anyone help?

Dear Dgandley,
If it should go wrong with the drive (which I honestly can't imagine), at least you tried the cheapest option and you're still be able to buy a new computer. It's an easy job installing those drives, certainly much more easy then in a MacMini! And harddisks come usually with 3 or 5 years guarantee. The only thing you should be aware of is static electricity, so ground yourself and don't touch the electronics!
Seagate is not the best choice, because of firmware problems with some of those.
Take my advise and do what I did: buy yourself one (or maybe two) 640 GB Western Digital WD6400AAKS "Blue" drives and you'll have one of the fastest, coolest running and most silent universal drives you can get for your good money. It's not the large capacity that counts here, but the overall speed of this particular type of harddisk (the 320 GB version in the same series has proven to be much slower!).
For super fast booting, devide it in f.i. 150 GB for the first partition (that's the outer part of the spindle with platters inside, which rotates at the highest speed), and reserve that for your system and applications only. The rest can be used for storage.
Again, success and best regards,
Robbert

PowerMac G5 freezes, fan is blowing hard

Hello everyone:
My PowerMac G5 is about 3 years old, running OS Tiger 10.4.11 and has been working fine. A couple of weeks ago, it started freezing up overnight with the fan going into overdrive and blowing hard. I can only shut it off by pulling the plug. At restart it makes 2 clicking noises, and then it boots fine--and works fine until the next freeze.
It started happening more often which prompted me to run the disk utility. It came up with a message that "Volume header needs minor repair." I repaired it using the OSX CD.
Question: does anyone else have the same problem and did the utility fix the problem for good? Or should I be thinking about a new hard drive? Thanks in advance for your help!!!

I can say I have the same problem with different results. I too have been noticing this is primarily happening when I out the machine to sleep. I will wake up in the morning to find the fans going full blast. I have also encountered getting a phone call from someone at home telling me my computer sounds like it's about to blow up! I put it to sleep each morning after checking my emails and heading out to work. At times the room can get get a bit warm and this may be adding to the issue. I have also read not to use any animated screen savers (which I have been) and so I may just do away with those to see what happens.
I have recently encountered more system freezes where I will have audio playing, the machine locks up with the audio sounding like a broken record repeating itself. The only way to get out of it is a hard reboot by holding the power button in. Same way I have to reboot it after I find it in the morning with the fans at full speed. I have also encountered a few kernel panics as well while in the middle of working in Photoshop or web browsing using Safari or just checking emails.
I have run the Apple Hardware Test CD both Quick and Extended Tests and get a pretty balanced result of everything is OK, or a Logic Board failure where it gives me this error code - 2STH/1/2:CPU B AD7417 AD1 - from which all I have been able to gather is something to do with a thermal sensor for one for the CPUs?
My CPU die temps are not horribly hot although I notice CPU B usually runs about 7-10º F warmer than CPU A. This is pretty constant as well no matter what task.
I have reseated all the boards, used compressed air to clean it out, cleaned the fans and radiator the best I can. I had one of the CPUs replaced less than 3 months after having bought the machine from Apple. I sure hope one of the CPUs is not going bad again as my AppleCare just expired 2 months ago.
I'd really love to know specifically what the error code I get from the AHT means. So far, I have been blessed not to see any leaks inside the case which seems to becoming a more frequent issue with my model machine.
I too am very interested to hear from others who are experiencing this issue. My S.M.A.R.T. status is good so I know my HD is fine. I have swapped out graphics cards and memory to the originals, neither of which have changed anything. Going to try reseting the SMU on the board again along. Also replacing the SRAM battery even though I know it has nothing to do with this specific issue. I just notice after forcing the machine to shut down and reboot, the date likes to come up as 1969 a lot of times.

HP Photosmart Studio freezes after launch

Does anyone else have a problem with HP Photosmart Studio freezing/not responding as soon as it is launched?
I have a 15 inch MacBook Pro running 10.5.5, though the problem has been the same since 10.5.1.
I have uninstalled and reinstalled the latest software from the HP web site, deleted preference files, repaired permissions etc but the problem remains.
Any help would be welcome.

I can confirm that I, too, am encountering problems with HP Photosmart Studio (version 9.6.9) that is mystifying me. I spent about 10 hours trying to figure out the problem, but I did not come up with any solution.
I have not yet explored all of the HP software features that came with my HP Photosmart C7280 All-in-One, which so far seems to be a very fine machine that has delivered full functionality in printing, scanning, copying, and faxing. The one feature that does not seem to be functioning properly has to do with scanning a JPG image to the HP Photosmart Studio. Every time I've tried to do that, I get the same result: the image gets scanned OK and is deposited into a folder called "Scanner Output." That part is good. However, whenever the Photosmart Studio application is launched—either as part of the scanning process, or if I just launch it independently of triggering a scan via the HP Device Manager—the Studio application delivers a spinning sundial gauge next to the "Keywords Album" item for about 30 seconds, which is the followed by the spinning beach ball, indicating that the application is not responding. I must Force Quit it.
That is what has happened since I first installed the HP software on my PowerMac G4 running Tiger, 10.4.11. Uninstalling the HP software and reinstalling it does not fix the problem. The thing that mystifies me is that I cannot discern if the problem lies solely within the HP software or if there is something wrong with Tiger on my PowerMac G4. The reason I say that is that, in order to isolate the problem, I ran comparative tests of the same, freshly reinstalled HP Photosmart Studio on an iMac G5 running Tiger 104.11, and I did not have problem getting a stable Photosmart Studio window to appear. The same spinning sundial gauge appeared, and it spun for awhile, but it eventually disappeared and the application became functional, unlike on my G4, when the spinning beach ball appeared.
Additionally, back on my PowerMac G4, which also has partitions running Panther and Leopard, the HP Photosmart Studio application, which resides on the Tiger volume, loaded OK when I re-started the G4 under Panther and Leopard. However, I do not consider that a solution, since I could see no way that I could access images that were not on the startup drive.
I wish I could say definitively whether or not the problem lay within the HP Photosmart Studio component of the quite extensive software package that came with the All-in-One, or whether there may be something amiss, or incompatible, with the Mac OS. But all of my tests thus far do not allow me to reach any definite conclusion. As you requested, it would be nice to know from others if this software application works or not with the Mac OS. For me, I guess I am just going to have to work around that particular feature, at least on the Tiger volume on my PowerMac G4. Strange, though, isn't it?

Edit:
Here it is: http://www.tweakenl.info/Picture 2.png
But the strange thing is.
I can see now only one CPU :S the other one is gone.

Re: Satellite C870-1J6 -Win8 freezes

Hi everyone,
My Satellite sometimes "freezes" wich is becoming quite annoying. It's been doing so since the very start and the moments appear to be random. Weither i'm using chrome or typing in word doesn't really matter. I'm running on windows 8 and couldn't find anything in the previous posts so thought i might ask...
Any thoughts anyone?
Best regards,

The mentioned freezing isnt a real freeing but I guess during this short period (30sec) the system does not respond because something stress and load the CPU.
I think some background process might be responsible for that
Start the task manager (win key + x -> task manager)
Within the task manager you could check the tab processes. Keep eye on the processes which needs the CPU performance while these short interrupt happens.
This could help to get more details about the freezing reason.

Can No Longer Play .M2V In QT

Hello,
I have been having trouble with a Dual 2.7 Powermac lately (freezing). I did an archive and install from my OSX 10.4 CD. I also ran disk repair from the startup cd, and repaired permissions, then ran Yasu (the correct version for tiger) to clean cache files. The mac has been running solid now for 2 days!
However, I have just realized today that I can no longer playback .M2V files in QT 7. I am not sure when this problem started but I do know that I used to be able to do this. I have FCS Installed (FCP5, DVDSP4, Motion 2, STP) and am running OSX 10.4.4 and QT 7.0.4.
My .M2V files (encoded with BitVice 1.6) import and play fine in DVDSP4. Any help would be appreciated as I usually do rough previewing of Encoding settings in QT.
Thanks,
Matt

I had this problem a while ago and somebody worked out a solution. If my memory serves me while you have to find your .m2v files and Command click on more than 1 file, so they do not try to open. Then control click on one a .m2v file and go to the "open with" submenu. Tell it to open with Quicktime 7 and tell it to always do so. See how you go.

Dual G5 2.5 missing processor.

I've been using a dual G5 2.5 for ages and I just realized lately that my dual G5 went from dual to single! While researching around the Internet, I saw that there are multiple instances about the liquid cooling leaking and killing machines.
Anyone dealt with this problem?
Many thanks.

Me and two friends use Macs for making music, I've had 4 iBooks, all off which had Logic Board failures. They were replaced until they were out of warranty. I've sent back countless iPods, and I believe this isn't the original PowerMac I bought, I can't remember why it went back cause I'd only just got it. But know this one's almost dead.
One friend, has always had iMacs, he's had similar problems with Logic boards and the Screens losing alignment.
Another friend a professional musician also had countless PowerMac problems, i think he's onto his 3rd.
All 3 of us of could just be unlucky, but I find that highly unlikely.
All the ice white plastic and brushed alluminium doesn't make it a Super-computer.
I'm slowly beginning to realise this!
Our consumer rights in Britain state any electrical appliance should last a reasonable amount of time, I don't call 3 yrs a reasonable amount of time for a £2000 computer.
Apple make a big point of being environmentally friendly these days... It would be a lot more environmentally friendly for me to be able to fix this powermac for a reasonable price (not £400-500) and have to spend more money disposing of this one and replacing it with the newest shiny model.

My Macbook Pro started freezing all the time & going to sleep on its own for no reason

I've been having trouble for a few weeks with my computer freezing way too often for seemingly no reason - I'm using it exactly the same way I always have with no problems, and even actively trying to have less applications open (which seems to have no effect). I can't always load simple webpages without it freezing and giving me the color wheel and it's just MUCH slower in general. It is seriously making it difficult to use my computer for work or for fun...
It has also started going to sleep on its own - the screen will just go black (or sometimes BLUE) and the keyboard lights turn off, and the only way to get it to wake back up is to close the computer, wait, open it again and click or press a key. It doesn't respond to any keys/clicks until it has been closed and reopened.
It seems to overheat really easily lately as well - but it does not always overheat when it freezes.
SMC reset did not seem to have an effect. Activity Monitor doesn't show anything crazy, everything is pretty much 0% except Firefox around 7-12% as I'm typing this. 246 GB available on my hard drive so that doesn't seem to be the problem either. Right after restarting my computer it seems better but the problems quickly resurface...
I googled for help before posting this and someone had suggested running the command
syslog -k Sender kernel -k Message CReq 'Channel t|GPU D|I/O|find tok|n Cause: -' | tail | open -ef
in Terminal, which they said "Normally the command will produce no output, and the window will be empty." But mine gave this:

I don't know what that means or if that is useful info to help solve my problem? I just want to know what I can do to make my mac go back to normal!

Eric - I dont understand how I'd use caffeinate. I am not running any code or particular script. My system goes to sleep if surfing the web, or running Word or Excel, etc.
Or.. Are you saying I should go through and type 'caffeinate X' for all of my applications?

Macbook pro freezes for no reason even after installing 10.8 on a brand new hard drive

Macbook pro freezes for no reason even after installing 10.8 on a brand new hard drive.
Tried to reset pram, smc, nvram.
Tried installing new RAM.
Tried installing new hard drive.
You should know that my internal drive is installed in a cheap external case and plugged in a USB 2.0 port because i am waiting for a new hard drive cable.all
Yep all good things happened to me...i don't know if all these problems are linked, ahh and also my trackpad is behaving very erraticaly sometimes, it's like it is possessed by a ghost. My computer is not under warranty anymore so i'd like to avoid a trip to the Apple store but i'm close to doing just that.
Any help appreciated...

It's diagnostic software. It's supposed to help you find problems. I don't think anyone is making any software yet that fixes hardware problems.
That said, the two comments:

would lead me to think it's the logic board. On older MacBook Pro's both the USB I/O ports and the keyboard/trackpad are fed out of an integrated USB controller integrated into the South Bridge I/O controller. On newer models, the USB ports come out of an integrated North/South bridge controller and the keyboard/trackpad are handled by an SMC controller, which itself interfaces with the I/O controller. All of these items are on the logic board, and they're all unrepairable.
...unless of course the "internal drive [that] is installed in a cheap external case" is itself causing the problems. Another thing to try might be a different USB port, if you haven't done so already.
I didn't know the price for Scannerz went up. I could have sworn I only paid 30-some bucks for it. Maybe it was on sale at the time. I don't remember.
In any case, good luck.

Laptop Toshiba P50-A-K9M often freezes due to unknown reason

Hi,
My Toshiba P50-A-K9M constantly freezes due to unknown reason. My OS is Windows 7 64-bit.
Initially I thought that it was due to overheating. However, when I enabled CPU temperature monitor I noticed that freezes happen even if the temperature is relatively low (39%).
My second guess was about memory. But Windows memory diagnostics passed without any problems.
I can't confirm it but I've a feeling that it happens on CPU intensive tasks but it's not linked to particular program.
I had freezes while compiling an Android application, other times it was during browsing in Google Chrome... I even had a freeze when only File Explorer and Image VIewer were running in foreground.
Could you help me with this problem?
Thanks,
Leonid

Try removing one of your memory sticks and run it that way. Try one at a time and in different memory slots to fully test your memory.
Run a boot time virus scan
Run a full disk check to test the hard drive.

MacBookAir freezing for no apparent reason

My new MacBookAir freezes for no apparent reason (e.g. in the middle of a Word document, in the middle of a Skype call, as well as in native Mac applications). Happens at least 3-4 times a day. Also seldom comes out of sleep without hanging. Hardware test says everything is OK. As a long time Mac user this is very disappointing and frustrating. Ironically Windows 7 on Boot Camp seems to run just fine. Makes me wonder why I bought a Mac - won't be buying another one anytime soon. Any ideas?

Not a temporary freeze - get those as well.
This is a full freeze (left it for a few hours without result).
Forced reboot - hold down the power key until it shuts down, then restart.
