Power Mac G5 :: System Will Not Boot Properly And Loud Fans

My husband's Power Mac G5 won't boot properly -- it hangs on the grey Apple screen, after which the fans in the unit come on really loudly, and the unit eventually shuts itself off. We've cleaned out the unit, all the vents, and checked the fans -- they seem to be working properly. Opening the case while the computer is on shuts one of the fans off, but the others are still really loud. We took it to a Mac store, which diagnosed a hard drive issue and suggested data recovery and an installation of a new hard drive for $500.

We are really broke at the moment and cannot afford something like this. So we've bought a new hard drive and are going to see if that solves any issues. When we got the machine back from the store, I booted the machine from the install disk (holding down "C" while the machine booted), and got a boot from the hard drive instead. No "install" screen showed up. Tried a re-start while holding down "C" and the same thing happened. I tried to run disk utility from the install disk, but the "repair disk" option was greyed out.

I ran "repair disk permissions" anyway, and tried to restart in safe mode, which resulted in a panic kernel message. Tried it again, with the same results. I was trying to write down the full panic kernel message, but it shut itself off in the midst of my writing. Meanwhile, I've been reading on the forums that this issue could be caused by:
faulty logic board;
old battery that needs to be replaced;
failing thermal paste.

Power Mac :: Mac Pro No Boot Sound, Black Screen And Loud Fans
I've had problems with my Mac for a while now. First of all, it indicated ram problems with 2 beeps. I later fixed this by moving and changing around modules. It was solved, but now a new problem. The Mac seems to turn on, making its iconic sound for startup, but the screen remains black. After about a half to one minute, the fans go crazy and I have to shut it off. I've tried a few things like holding shift or alt, but that doesn't work as it doesn't even display a white screen. 

I need to know what to do and I don't really have the time to buy new parts right now. I'm really a windows based pc fixer by the way so I'm new to fixing macs.

Power Mac G5 :: Fans Spinning Very Loud?
This doesn't happen every day but its happened at least twice now where I've walked into the room where my computer and have it found the fans to be spinning super fast and making a very loud noise.

My computer was SUPPOSED to be in SLEEP mode.

What is this a sign of? How do I correct the issue? I had to do a hard shutdown of the computer to get them to stop.

Power Mac G5 :: Computer Not Booting - Only Loud Fans At Sttartup
I took my Powermac G5 to the store today to get a new monitor. We were going to plug it in and try it there to make sure it worked, but they didn't have the right cable and I didn't bring mine, so I brought the computer and the monitor home to try it. Now it won't work! When I press the power button it turns on, but the fans run really loud for a long time and nothing happens. I tried it with the old monitor too, same thing. They say they are getting no signal. What happened? All I did was turn it off, unplug it, and take it to the store!

I was with it the whole time, it never got dropped or hit or anything. What do I do? My computer's serial number is not in the list of G5s covered for a power issue. I can take it in tomorrow but if there's anything I can do tonight, that would be great! I didn't back everything up because I figured all I would have been doing was testing a monitor, not doing anything with the system itself. I'll be very sad if I lost some stuff permanently.

Power Mac G5 :: Spinning Gear At Startup & Sometimes Loud Fans
so I see there are a lot of topics about spinning gears. However, I can't open my drive to put in a OS X install disc (I'm running tiger) to repair it. How can I open the drive? And what type of holding down keys do I need to do?

Power Mac :: G5 Fans Running And Making Loud Noise Before Crashing?
I was out of town so this description was second hand but the computer has been running a little weird for a while. When I have too many apps open or on a website that has a lot going on...the computer starts revving up until I quit out of everything and let it slow down. I guess while I was gone, this happened but nobody quit out the apps and it eventually turned the screen black. When I tried restarting it sounds like the computer is working but the screen is black so I can't see if it is booting up or not. I took the monitor into the apple store yesterday and it started up right away for them. It's a cinema 23" I think.

Power Mac G5 :: Loud Wild Fans - Hang Ups And Hard Reset
I have a DP 2.7 G5 Tower and lately I come into my office to find it with dark screens (dual monitor setup), and I am unable to in any way control it by the mouse or keyboard. I imagine it's "hung?" The fans are on full blast and it sounds like it's planning to take off at any moment. I've awakened in the middle of the night by the sound of it and it's in that same state. What to do? I restart it at the power button. I then have to run Disk Utility to verify all the disks and RAID setups.

Anyway, I read about the coolant leaks issues. I started running a temperature monitoring program for the past few months, and its been doing about the same type of pattern since I started monitoring it. Doesn't appear to be unusual. Everything appears to be working fairly well, except for this issue. System is OS X.4.11, and checks out fine with Disk Utility. So far the hard reboots haven't done any damage to my disks, but it worries me greatly. Also the "liquid cooled" aspect worries me greatly.

Power Mac G5 :: Quad Doesn't Start Up - Crashes And Fans Become Real Loud
I started having problems with my PowerMac G5 Quad 2.5GHz (late 2005) about a week ago. First I found the computer with the fans running at full speed (really loud) after leaving the computer alone for a while (instead of going into Sleep mode). At this point, I wasn't able to recover it from that state and had to force it to shut down by holding down the power button. Another thing that caught my attention was that a couple of red LEDs were on (just behind the power button). Last night, after finding the same situation and shutting down the computer, it would no longer start up. I could hear the hard disk starting to spin and the chimes sound, but I'd get no video at all (no gray screen or anything). After trying 3-4 times, the computer finally started up.

The situation got worse this morning, as again I found it with the fans on full blast. Now I can't get the computer to boot anymore. I no longer here the chimes sound or get a video signal at all. I can't open the CD tray either (it doesn't seem to recognize the keyboard) so I could not boot from a CD. And holding down the power button is no longer shutting it down, now I have to unplug it. I've already tried relocating the RAM, resetting the SMU, and read about resetting the NVRAM (however, this was not possible as I have no response from keyboard input). I've not installed any new software or hardware lately so maybe this was caused by the latest software update. After reading forums and searching the web, it looks like this problem has become quite common in the past few weeks. Has Apple taken any steps to solve this problem on the affected computers?

Power Mac G5 :: Boots Up And Hangs At Gray Apple Screen - Fans Rev Up Loud
I am so confused. For some reason my G5 boots up, I hear the tone, and it gets to the grey screen with the apple. The circular "wait" image never comes up and then after about 1 minute, the fans rev so high it sounds like my computer is preparing to take off! I tried taking out all the RAM and reseating it. I even tried booting with each pair one at a time. I tried removing the battery, and putting it back, I tried unplugging, resetting the PRAM, removing the DVD drive, and replacing the DVD drive. No luck. about 4 weeks ago i was able to get it to start up with an install DVD in there when (and this may be dumb luck) I tried a trick I read on these forums where you use a hair dryer to heat up the RAM board. I reinstalled Tiger and it seemed to work perfectly. Then it revved up the fans and froze, no kernel panic on the screen. The heat trick did not work again. Now all I get is the grey apple screen with revving fans. It won't even recognize that I have the install DVD in there when I hit the "C" key.

Power Mac G5 :: Start Up Won't Get Past White Screen - Fans Blow Loud
I have a G5 single 1.8GHz (late 2005 model?) serial number YM439***QYT It gets stuck on the White Screen at startup. A minute later the fans start to blow really loud and it just keeps doing that and does not boot up. I was using a hard drive that was copied from the original drive. So I put the original drive in and it was fine for a day. Now the computer is doing the same thing at startup with the original drive, as explained above. I reset PRAM & NVRAM, nothing. I have two different video cards, that's not the issue. I do not have the OS Install Disc as this computer was given to me as a gift.

Power Mac G5 :: Fans Come On But No Display On Boot
I have just got a 2004 power mac g5 off my parents to see if I can fix. The Mac has been sat unplugged for a year or so, and when you come to switch it on you hear it start up and the fans come on, but there is no video. I looked on the support section and it suggested resetting the PRAM but unfortunately I don't have a Mac keyboard for it so I'm guessing I can't do this.

Power Mac G5 :: Will Not Boot - Fans Run High Only?
My back up 1.6 ghz G5 power mac is misbehaving. I moved the system to another room and when I went to boot up, the only response I got was the fans running at normal speed - and then they started to slowly creep up to a very high speed. No hard drive activity, no monitor activity. I swapped out the memory for the original factory mem - same problem - reset the switch... nothing.

Power Mac G5 :: Fail To Boot - Fans Sound Tired
For the past month, I have been getting random bombs where the screen freezes with a strange distortion pattern across the entire screen. (See linked picts:[URL]. This would happen at completely random times and about once every other day. I ran applejack and it went away for about 2 weeks. Then it came back hard (twice in one day). Thinking it was the graphics card, I unplugged the computer and took the graphics card out, gave it a good look over (one of the connector pins showed silver instead of gold), cleared out the dust carefully and put the card back in.

After cleaning, I restarted the computer and saw an exclamation point on the screen [URL]. This looks really bad, so I forced a shutdown.

Now every time I startup the computer, the fans are making strange noises and the computer will not boot. Here is a short clip of the fan noise. [URL]I have booted it 7 times tonight and it started successfully once. When it did boot, the date was reset to 1969 but everything else seemed normal, shut it down and can't get it to boot successfully since.

Power Mac G5 :: Unable To Boot And Fans Turn On Full Blast
When I turn on the PowerMac, I get the gray screen with the Apple logo, but no spinning wheel. It just hangs on the screen. Thinking this was an issue with the hard drive, I attempted to boot from a backup image on a firewire external drive. I open up the startup manager and see the backup image, but the same thing happens when I attempt to boot from it. It just hangs on the gray Apple screen with no spinning wheel. After a few minutes, the fans turn on full blast.

Here is everything I have tried:
Starting from external backup image
Re-seat RAM
Reset PMU (pressing button on logic board)
Tried booting to Open Firmware: reset-nvram, set-defaults and reset-all. Computer freezes after giving it the reset-all command.
Tried booting into Safe Mode. Didn't work.
Tried going to the console (Cmd + Shift). Got into the console, but computer freezes before I can type anything.

I have a feeling that this is a problem with the logic board. However, without being able to boot from anything, I can't run any sort of hardware test.

Power Mac G5 :: System Freezes And Fans Out Of Control
We own a Power Mac G5 - bought in April 2005. We upgraded to Tiger years ago and very recently upgraded to Leopard - 10.5.6. Since the upgrade to Leopard the system has been freezing up. The freeze up is followed by the fans increasing in speed as if the box is about to take off. Subsequent to the initial freeze, it freezes ever after at start up and we can move no further. To stop the fans and turn off the machine, we have to hold the power button down until it turns off.

We've visited the Genius bar twice. On the first visit, the Genius ran a complete diagnostic, but found nothing wrong. He suggested that we possibly do an Archive/Install. We never got to that because we had the same problem again at home. On our second visit, we were able to reproduce the problem at the store. The Genius suggested that we have a problem with our graphics card. Apple replaced the graphics card. We took the machine home and used it for about 4 hours and then it froze.

This is extremely frustrating because we cannot do any work on the machine (including diagnostics). We never know when it will die and most of the time we cannot get beyond start up. The Apple employees have been great, but I'm not sure anyone knows the answer to this problem. This was an expensive machine and we are very concerned about losing it.

Power Mac G5 :: Dual 1.8 G5 Won't Boot Fans Running High
So last night i deleted a folder which was full of documents (school docs, nothing important). I then went to empty the trash and the little emptying the trash progress box popped up but nothing was happening. I was then unable to cancel the trash empty, and also unable to open any programs. I even attempted to restart the computer from the software but that wouldnt work. I then did a hard shut down by holding down the power button.

Now when i try and start up the computer it goes to the gray screen with the apple logo and the spinning thing underneath it (not a beach ball). After about two minutes the fans slowly begin to spin higher and higher until their running at full bore. I've tried a PRAM,and a PMU reset. I've also left it unplugged for about 10 min and tried to boot it again. I am able to boot into open firmware mode. I don't have any of the discs to do a hardware test. I've not updated any software, or any hardware, and I'm running 10.4.11. Is there anything else i should try.

Power Mac G5 :: Doesn't Boot - Black Screen - Fans Spin Up And Down Repeatedly
I installed a new system drive in my G5 today, installed the OS and Logic but while I was sorting the MOTU drivers it froze. I had to reset it at the plug but when I started it again it wouldn't boot! When I start it, all it does is start spining the fans(I assume it's the fans I'm hearing)for 2 seconds then stops then repeats the starting and stoping over and over. The screens are black. I haven't used the G5 for about 2-3 months if this makes a difference. What's going on?

Power Mac G5 :: Fans Work Fast When System In Sleep Mode
I have recently a problem with fans in my Power Mac G5. It happened only three times since November but I'm worried. In those cases, when my computer went to sleep, the fans started to work very very loud and I couldn't wake up the system. The only solution was to shut it down manually. Could you please give me any hints what can be wrong? I don't have any external devices plugged in; just a mouse, keyboard and a tablet.

Power Mac G5 :: System Will Not Startup Properly
Woke up this morning to find my 2GHz PowerPC G5 iMac (purchased in 2005) will not start up properly. I'm running Mac OSX 10.4.11, and my last software update was iTunes on July 18th, about two weeks ago. I have not installed any new software in the last two weeks. At first I had a blank blue screen. I did a safe boot and removed the startup items in Library/Startup Items. I also went into system preferences, to accounts, and to "login items" where I removed two items, one for iTunes and one for MSN messenger. I had three third party folders in that folder which have been there for over a year.

At this point, my start up screen got to the login screen where everything froze except the mouse. Back in safe boot mode, I went to the disk utility application and did "repair disk permissions". I received the message "The privileges have been verified or repaired on the selected volume." Restarting normally, the login screen came up and I was able to type in my password. The desktop came up, it loaded normally for about 5 seconds before freezing. So I restarted the computer in single user mode, and typed "/sbin/fsck -fy". I received the message "The volume Macintosh HD appears to be OK". Now I get varied start up results, including blank blue screen, grey screen with apple symbol, and frozen login screen.

Power Mac G5 :: Won't Wake From Sleep / Fans On Full And Wont Boot To Hardware Test?
PowerMac G5 Quad 2.5ghz. Stock Ram, no USB or Firewire attached, erase and install Leopard and updated to 10.5.4. Only thing not stock is the ATI x1900GT Vid Card.

When I select Apple Menu > Sleep... it sleeps but it wont wake up and after about 20 seconds the fans go full speed. Only way out is to hold power button for 10 seconds to shut down.

Also when I try to boot with the Apple Hardware Test disc in, and hold Option to select it, the screen is nothing but blank. It sounds like it might be going to the select screen but I cannot be sure.

Other wise this machine boots up to the desktop and runs normally.

Mac Pro :: Fans Making Loud Noise For Few Seconds On Startup
I just received my new Mac Pro from apple on Saturday. This thing is a beast! I am planning on running apps from Final Cut Studio 3, Photoshop, After Effects, and others. 2.66 Quad/6GB RAM (OWC)/640GB HD/ATI 4870

I have a few questions.
1.) Is it normal for the Mac Pro's fans to make a lot of noise when you first start it up or wake it from sleep? My fans make a lot of noise for about 16 seconds or so.
2.) I am planning to put a second optical drive in it. Is there a way to eject only one tray at a time, or will it do both?

Now, I am selling my iMac for around $800 and I am looking at some upgrades:
An additional 21.5" Acer LCD display
A mini display port to dvi adapter
A LG blu ray burner
Two 1TB samsung internal HDs
A blu ray player (I do not have one yet)
Elgato Eye TV hybrid

MacBook Pro :: System Making Loud Noises / Loud Sound On Start Up ?
I just bought my MacBook Pro last week. When I power it up, it makes a loud noise for about a second and a half. I think it's the hard drive starting up or the disc drive. I'm not sure which one, but it's pretty loud, so I was just wondering if anyone else noticed this and if it is normal.

Software :: Fans Really Loud And Black Screen
I have a Power Mac G5 that turns on but there is no chime- a black screen and after 3-4 minutes the fans start running flat out and get loud. I have tried unplugging everything- plugging it all back up, starting and holding down command option P & R but nothing is helping. It has no apple care so they will not help troubleshoot it.I turned it on tonight and it powered up fine- Then as i was checking mail the screen went black.

IMac Intel :: LOUD Fans Even On Slow Speeds?
my iMac's been getting hotter than usual, so I installed SMCfancontrol & istatpro to keep an eye on the tempuratures (cool down if needed), I took my iMac to an apple store who said the hardware is fine after running tests & said there was nothing wrong with it (I still consider it too hot though).
Which leads me the attribute the raise in temperatures to my recent upgrade to Snow Leopard as many people have reported the same issue, my intention was to downgrade as soon as I can.

OS X :: Loud Fans On 10.6.1 MacBook Pro / Make Them Normal?
Anyone else experiencing this? My fans have been going pretty much nonstop audibly since the 10.6 install. The "normal" for the fans is about 2000rpm, and now they RARELY dip under 3000, and the "new norm" is a very audible 4000-5000rmps.

This is SO annoying! Anyone else?

Power Mac G5 :: Noise From The Fans And The Blue LED Next To The Power Button / Not Booting?
I have a problem with one of G5s at the office. I'm afraid it maybe the logic-board. The machine took a hit from a power surge. I get noise from the fans and the blue LED next to the power button. But I get no video or no HD action. The drive was fine, I moved it to newer PowerMAc and I booted with it.My guess is that the Logic board is dead. Do you guys know if I can do any tests to confirm. My next step is to take it to an Apple store.

Power Mac G5 :: Dual Boot With Leopard And Tiger On System Drive
I've got a Dual 2 GHZ Power Mac, that I recently put Leopard on. Unfortunately there's a program that I need to used for a job that doesn't play well with Leopard. What I was wondering is if it was possible to partition part of the system drive and load Tiger back onto it, and then be able to boot from either Tiger or Leopard. That way I can load the programs that are only friendly with Tiger on to that partition. Or do I need to get another drive entirely and pull the Leopard system drive out?

Power Mac G5 :: No Boot Up From System Disk Or Tech Tool Pro 5
I suspect my system drive was having some issues as it sounded like it was being taxed and strained as I would open up applications from it. Upon verifying the disk using Disk Utilities, the test would stop short with the following message:

First Aid Failed
Disk Utility stopped verifying "Macintosh HD" because the following error was encountered
Filesystem verify or repair failed
In addition, an error message came up (in red) on the disk utility screen as well saying:
Volume header needs minor repair
The volume Macintosh HD needs to be repaired
Error: Filesystem verify or repair failed

Normally from here, I'd start up the computer from the Tech Tool Pro 5 disk (holding down C key upon restart). But when I did this, the computer never responded. Instead, the power was on but the screens went black and the computer went into a very quiet "idle" mode. After about a minute, the fans began ramping up pretty high (and loud). This went on until I finally had to manually shut down the computer by holding the power switch down for a few seconds. I didn't know what else to do. Those fans were not coming down (not even after 10 minutes).

Anyway, I pushed the power button again and held the C key down. Still, nothing. The fans stayed idle, for a little while and then ramped up again just like last time. I hit that same dead end and powered down the computer via the power button. Is there an alternate way to boot the computer from Tech Tool Pro or the original start up disks? I'm on my way into town to purchase a new internal drive (something with about 1TB of space) so that my pro apps can swim a little instead of being being bogged down on a 250G drive.

Power Mac G5 :: New Power Supply Now Fans Running Continuously
About a week ago, my G5 went dead - no power at all. An Apple certified tech that I know came to my house yesterday to replace the power supply with one (600W version) that I ordered. That got me up and running, but ever since then, ALL my fans have been running at high speeds nonstop. I looked to see if there is a firmware update and tried resetting the CUDA again - same results. Tried setting processor speed to reduced, even tried it on highest - same result. Only way I can get them to stop is to to the computer to sleep or shut it off. The fans were never like this before.

My XServe always has the fans running at the same speed. I have never heard them slow down, or even speed up. When I look at the server monitor, they all appear to stay around 4500 RPM. Anyways, is there a way to control this, or even get replacement fans?

MacBook :: Hard Drive Fans Loud When Watching Movie
I notice that while streaming a movie, watching a dvd or playing a game my hard drive fan is so loud, its annoying. I have a 2008 White Macbook and i replaced the stock hard drive with a western digital 5400rpm 320gb and I only have 1gig of ram. I have no problem replacing the hard drive for a 7200 but i just need to know if its worth it. If i were to upgrade the ram to 2gigs would that solve the problem? Is it possible to install a 500gig drive into the white macbooks?

Power Mac G5 :: External Hard Drive - System Won't Boot
I recently purchased a Western Digital 750 gb hard drive. I reformatted it to Mac Journaled and it is connected through firewire 400. It works great and all, but I've noticed that it has significantly slowed my system startup time when I press the power button (recently, it won't start at all). After I unplug the firewire cord and press the power button, it starts normally. I'd rather not have to unplug my hard drive every time I turn my computer off.

MacBook Pro :: 13 Inch Early 2010 Gets Really Hot And Fans Get Really Loud?
I have an early 2010 MBP (13 inch) whose RAM I upgraded to 8GB and the hard drive I upgraded to 750GB.Ever since I installed OSX Lion it takes ages to boot up (far slower than Snow Leopard which booted up almost instantly from turn on).Furthermore, when running, it gets very hot when running Windows virtualisation software inside OSX (VMWare Fusion 4/Parallels Desktop 6/7 - same results) and the fans turn on and become noticeabley loud.The machine is still under Applecare Warranty, is there anything I can do myself to resolve this, especially the heat/noisy fans?Is it due to having to work harder to virtualise Windows inside OSX and so run both systems concurrently, thus requiring more resources?
