PowerPC :: G5 Freezes After 5 Minutes Of Booting

My computer, a Powermac G5, Dual 2.0Ghz, 1st Edition Released Oct 2003, will just freeze. It usually happens within 5 minutes of booting into the operating system. I am also unable to boot from the Leopard or Tiger DVD's to try and install a fresh copy of the OS as they freeze during the install. This is what I have tried so far, but to no avail:

Resetting the RAM and Graphics Card
Resetting the Power Management (PMU)
Resetting the PRAM

Now this is the even stranger thing. I installed a copy of PowerPC Ubuntu Linux 8.04 and it works fine. This makes me think that it is unlikely to be a hardware issue.

IMac Intel :: Freezes 3-5 Minutes After Booting Up?
I've had my 24 inch 3.06GHz iMac for about 18 months now and it has always worked flawlessly. A few days ago, it froze without any obvious reasons. I forced it to shut down by pressing and holding the power key, rebooted it, and about 5 minutes later, it froze again. It kept doing this so I decided to do my usual troubleshooting procedure as follows:

-Zapped PRAM
-Reset SMC
-Booted up with Snow Leopard disc and ran Disk Utility (found no errors)
-Ran DiskWarrior (found no errors)
-Ran the Apple Hardware Test (found no errors from both short and long tests)all of Snow Leopard and had

MacBook :: Slow Booting - Takes More Than 5 Minutes
It seems that my MB(unibody 2.0Ghz) has some problem. I recently reinstalled leopard (and some softwares). It takes a little bit more than 2 minutes to boot. Worse comes with Windows 7 beta. I tried both 32bit and 64bit versions. It takes more than 5 minutes to boot! I saw some guy showing some comparison of boot time on youtube. It seems that Leopard should take < 1 minute and Windows 7 takes < 2 minutes (with the same hardware!). My MB takes around 3 times more than other MBs. Where should I start? I recently ran memtest and it turns out to be okay. HDD S.M.A.R.T also reports 'verified'. I'm not sure what would be the next.

OS X Leopard :: 10.5 Booting Very Slowly - Take Two Minutes For Apple Logo
A week ago I installed 10.5 and now it boots up very slowly. Or rather , it takes about 2 minutes for the Apple logo to appear and the process to begin.

I checked for firmware updates, but I do have the most current version for my mac Pro model installed. Also, the chime now has an echo. About one second after it has ended, it briefly sounds again. Don't know if that is relevant, but thought I mention it.

Power Mac G5 :: 5 Minutes After Booting Up, The Fan Turned On Loudly?
The fan continues to come on intermittently and then turns itself off. I plan on taking the computer to an Apple store to have it checked out, but was wondering if this is a common problem or indicative of something much larger? If I continue to use the computer, will something happen?

Mac Mini :: Booting - Mouse And Keyboard Doesn't Work For 2 Minutes?
I got a brand new mac mini 2.4Ghz just 3 weeks ago, got a few problems over the last week that I've been able to fix, but now I'm stuck with a problem when booting. The booting process seems a bit slow, and once the desktop has been fully loaded, the keyboard and mouse doesn't work, and the computer is using the non-calibrated Display Profile. After about 2 minutes, the display profile change to calibrated, and the mouse and keyboard work again. I have no clue about how to fix that problem, and I'm thinking about bringing the computer to an Apple Store by tomorrow if I can't fix it.

IMac :: Freezes After 15 Minutes Of Being On - Overheating?
My Imac freezes up a lot, usually after 10 to 15 minutes of being on. I suspect it has something to do with overheating. I have to get my data off of the drive before I take it into the Apple store for fear that they will will just replace the drive and all will be lost. I have a fan blowing on it now in the back and am copying data onto an external drive little by little until it freezes up.

I bought it last fall and have a 3 year warranty on it and this will be my second time bringing it in for repair. The first time it was a problem right out of the box when I brought it home and it was replaced. It's a 3.06 processor, 24 inch screen. I am not impressed by the hardware reliability and the all in one system. I am regretting buying the imac after being a PC user for so long and I am using my Windows PC to write this. I suspect the cooling system could be better on my IMAC given the compressed footprint.

IMac Intel :: Starts Up Then Freezes After Few Minutes
I have a 17 inch imac and I have had it for over 3 years. It had been working fine but when I came home from work yesterday it was frozen and the time said like 4 hours before. I had to do a hard restart and it would boot back up to a blue screen or sometimes to my desktop. I would even have situations where I wouldn't even get the startup noise and the apple logo, I would get a folder with a question mark on it. When the machine does start up I can navigate around for a few minutes before it freezes up. I have 2.5 gigs of memory as I added a 2 gig stick shortly after purchasing it. I reseated the memory and I still have the same issue. Keep in mind for keyboard suggestions that I am using a PC keyboard as my mac keyboard broke about a year ago.

MacBook Aluminum :: Freezes Every Few Seconds For Several Minutes
This problem started less than a week ago. I first noticed it when while watching a video file in VLC. After playing the same video file in other movie players, I noticed the clip froze in the same spot in all of them and concluded it was just another bad video file. Thing is, when it froze, it was so bad, my entire system froze. Now my laptop freezes every few seconds and lasts for several seconds at a time—too often and too long to do anything useful or productive with this machine. For example, typing this post should take me about a minute, but I've been toiling away for 5 minutes and counting. How can I stop this?

IMac :: Mouse Freezes After Few Minutes Of Startup
This is my first Mac user problem posting going back to my original SE! Power PC based imac running leopard 10.5.8 starts up but then mouse freezes after a few mins. Managed to change sleep mode to 15mins - same problem. Can't boot from Disk as same problem, also command+option and shift all still have mouse unmoved! Obvious change of keyboard and mouse have no effect. Could this be related to offspring's addition of ipad plugged into usb a few weeks back? He tends to unplug the device without ejecting!

I just upgraded to Leopard yesterday. The problem was there before Leopard but now it's 5-10 times worse. It usually starts with horizontal lines on the screen. The the windows don't refresh completely leaving a trail then eventually freeze and I have to power down. I was thinking it was a heat issue so I opened her up and dusted the fans except for the cpu....(hard to get to). I dusted the GPU and all. If I leave the computer idle, everything would look ok. Once I start using it, poof freeze (ball still rolling) forever (waited up to an hour) then I power it down. I just froze again. (I'm on a MacBook Pro). It froze after browsing the drive with finder.

Snow Leopard :: Desktop Freezes Up For About 3 Minutes After Start Up
This started maybe a month ago and I don't recall if it correlates to any sort of software update... When I start up my Mac the desktop freezes for at least 3 minutes. It seems that all log in items have loaded. I can use my mouse and the clock is moving but everything else stays frozen including all the dock items, mail, etc... until it all suddenly unfreezes. Any ideas? I'm not real familiar with terminal commands and stuff but is there a way I can check to see what is causing this?

IMac Intel :: DVD Drive Unstable - Image Freezes After 5 Minutes
My MATSHITADVD-R UJ-875 is consistently freezing up when I play DVD's - normal play only lasts about 5 minutes or so, and then the image freezes and the drive makes these cute little whirring sounds. DVD is undamaged but it's pretty pointless trying to get through a movie! If I reinsert the DVD it starts again from the beginning; no "resume playing" ability.

OS X V10.6 Snow Leopard :: MAC Pro 15" 2.4GHz's Freezes Every 12 Minutes?
I just purchased my mac book pro on the 18th of may from an apple store, brand new. I decided to upgrade the RAM myself since it is a much better deal, however once I replaced the RAM my computer began to run much slower and it began crashing (showing a gray window that says "please restart your computer" in many different languages) so i restarted my computer and the problem continues, after 12min of running that window appears. I replaced the RAM with the original and the problem still continued. I have run normal hardware tests and extended hardware tests as well as PRAM reset and still nothing changed. Does anyone have any idea what is going on? I'm totally lost on what is going on with my brandnew macbook pro!I should also add, I have been running the extended hardware test multiple times to see if it will crash during that and after 1hr it hasnt crashed yet.

PowerPC :: G4 Shutdown After 10 - 15 Minutes When Turned On
I just obtained an Ibook G4, it was my cousins, and it had crashed, so weeks later he gave up and bought a IMac. Anyway, the Ibook will turn on, boot up like normal. I had it turned on for about 10-15 minutes, and it just powers off. I had it plugged in, and it obtained about 11% battery, so I don't think it dies from battery shortage. Something I did notice, the battery charger cord, from wall to brcik is a 250V wire, while the brick it self needs about 100Volts. It isn't the cord that came with the Ibook. Could this cause the Ibook to shut down?

PowerPC :: G4 Lag - Startup Time 20 Minutes
I got a powerbook G4 with a smashed LCD. I hooked it up to an external monitor, and 1 thing keeps bothering me - it lags like hell. I have had an iBook g3, now using macbook aluminum, and I have never seen anything like this on a mac before. It lags like hell - it turns on in about 20 minutes. Sometimes it even doesn't. I have tried resetting Pram, Vram, premissions repair, looking @ activity monitor(nothing exceeding 2-3%). HDD capacity - about 55% full. I cant even describe whats up with it - launching any app takes about 2-3 minutes. For instance, iTunes launching takes 3,5 minutes and none of the songs are playable. I have tried to create a new account - did not help.

So lets start with system preferences. I have :
1,5ghz PowerPC processor
256mb Ram
Tiger 10.4.11
HDD 80gb Fujitsu MHT2080AT
So at first I though it was the lack of RAM - I bought a 1Gb stick. Now I am thinking it is because of the HDD. But I am not ready to buy another component randomly.

Mac Safari :: Safari Freezes After Some Minutes Working Properly / Fix It?

I am running Tiger... everything works just fine except the embarrassing battery life and unpredictable charging (b/c of the semi-broken power adapter).

PowerPC :: G4 Not Booting Up Properly
Yesterday I installed Ice Clean and ran a few of the maintenance procedures. This morning when I tried starting my laptop, it started with grey screen and apple symbol, then black screen with white text stating:
Mar 13 08:02:44 launched: can't exec /bin/sh for single user: no such file or directory.

I tried contacting Ice Clean, they claim it is not related. I checked my system profile and I thought I had 1gb of RAM it only says 512gb. Could a RAM failure cause this problem? Have started using target disk mode with my old faithful G4 and everything on the hard disk is still intact. Ran disk utility and all ok!

PowerPC :: PowerMac G5 Not Booting?
I have a PowerMac G5 dual 1.8ghz running leopard. It worked flawlessly since the day I bought it.

Then as of last week whenever I booted the computer I would get the gray screen with a black box saying to reboot the computer (in 5 different languages). I would reboot the computer. Same screen.

Is there some way to check what is wrong? Is this typically a hardware issue or an operating system?

PowerPC :: Powermac G4 Not Booting Up?
I was installing Tiger using FireWire from my Powermac G4 and it was nearly done when my Powerbook (target) died due to lack of battery... When the Powermac was rebooted, I get only a question mark and flashing smile.

I tried to test the C and T keys holding them down during boot up but only get the smiley face every single time... I even disconnected the secondary drive to no avail.

PowerPC :: PowerBook G4 No Longer Booting Up?
I know very very little about computer parts and things like that, but I hope to have provided enough information. When I boot up, both plugged into the power cord, and on battery, the powerbook will reach a white screen with an apple logo in the center. There also is a rotating disk below the apple logo. It will then shortly power down. I made a visit to the genius bar, and they told me something was wrong. I was like DUH!!! They said for $320 it would all be fixed, but I was hoping to be able to find out what was going wrong with it. Sadly I don't have the start-up disk that came with the laptop .

PowerPC :: G5 Not Booting - Fans Are Spinning
I opened up my G5, to install more RAM, and saw that one of the hard drives was unplugged (I just got it used), and so I connected that, blew some compressed air into it, installed the RAM and closed 'er up. Then I tried to power on and it didn't work (No Chimes, just fans spinning, no video, not even the start up chime). So, I disconnected the hard drive, took out the RAM I put in, and closed it, and it still doesn't boot. Same thing. My keyboard is wireless, but the wireless dongle thing doesn't get any power when it is "powered on". The fans are spinning all the time. (Except when it's powered off, obviously)

PowerPC :: PowerMac G4 Not Chiming Or Booting?
Have searched MacRumours and am unable to find a solution to my problem, so here goes: I've recently bought a "faulty" PowerMac G4, which would not boot, however all the parts inside were sold as working.

When I try to boot the G4 the light on the front flashes and the fans begin to spin but there is no characteristic Apple "bong" and nothing appears on the screen.

I know the screen's working because I use the same one with one of my Windows PC's. I've tried pressing the CUDA button and reseating the PRAM battery but to no avail. Does anyone know what my next step should be?

PowerPC :: Using IMac G5 With ISight Not Booting
I purchased the last generation iMac G5 when it came out a few years ago and I recently tried to sell it. I sent the item to the buyer and he said it would not start. The Apple logo or for that matter anything would not come up. He brought it to the Geek Squad at Best Buy and they said it was an issue that would most likely cost over $500 in repairs. I just got the computer back in the mail and all that happens when the power button is pressed is the white light on the front lower right hand corner comes on for a second, then the machine shuts down. You can also hear the machine begin to start for about two seconds, then it shuts down. Any ideas as to the problem and whether it is fixable without expensive repair costs?

Also after several minutes, you will hear a very loud noise come from the machine, the fan you can tell is extremely loud. Not knowing this stuff very well as i'm more a PC tech than Mac, what are some options to troubleshot?

PowerPC :: IBook G3 (Clamshell) - Booting From New MBP CD?
I recently came into possession of an iBook G3 (Clamshell) model M6411. Unfortunately, I believe it had a cactus HDD - it shows up in Target Disk Mode on my current model 13" MBP but refuses to format or read - locks Disk Utility/Finder up when accessed. The iBook also has NO CDROM drive in it, either (removed by previous owner, reasons unsure). I'd just like to get it to boot to see that everything else works ok. I have a retail install of OS 9.2.1 as well as an iMac G3 OS X 10.1 install CD, and a 10.3 retail disc too.

I am aware that PPC Macs cannot boot from USB CDROM drives, but they can using FireWire. So, I tried plugging it in via FireWire to my MBP, put the MBP in Target Disk Mode, put the CD in it, and held Option while booting the iBook. The iBook sees the CD on the MBP, I click on it to boot it, and it shows the Happy Mac (this is with the 10.1 CD). However, after about a minute, it shows a strange "broken folder" icon (a Mac OS 9 folder with a tear down the middle) on a grey background. It gets no further. If I use the 9.2.1 CD, it shows a Happy Mac briefly then switches to a floppy disk with a question mark. The 10.3 CD refuses to boot at all. One thing I forgot to mention is if I try and boot the iBook normally, it shows a Finder icon alternating to a ? in a blue Mac OS 9 folder.

PowerPC :: G4 Screen Changing Color / Not Booting
Yesterday I installed the latest security updates for my ibook via software update. I'm not sure if this is related to my problem, but I thought I might as well mention it. A few hours after installing the updates, I turned on my computer. Everything was running fine, however as I was listening to music and surfing the internet, my screen turned black. I checked the contrast and it was all the way up. The screen then turned completely off. Upon restarting the computer, my screen got to the loading page with the apple icon and the loading circle, and then turned black and flickered every so often with a screen of vertical multi-colored bars.

I held down the power button to turn the screen off, and the flickering increased, before becoming completely covered by the multi-colored bars and then shutting off. This morning I tried again and my computer actually booted up. However, after a few seconds the screen went black, paused for a few seconds, then went completely red, then green, then blue, then three shades of gray, and finally black again. It repeated this cycle twice before the screen turned itself off. Is this a virus, or hardware/software malfunctioning. I've had my ibook for two years.
