Jan 4, 2011My PowerMac G5 fans hardly ever speed up. I mean they certainly never go full speed or ever close how they sometimes behave on start up. I never get the jet speed noise. Even when I am rendering a movie in FCP, I hardly hear the fans. Right now on idle, iStat pro reports CPU A being 58C and CPU B being 56C. Yet, the fans are still only 400RPM both CPUS Intake/Outake.

Oct 26, 2006I have a strange problem with the powermac G5 1.8 SP, yes the one with the hardware bug. It was my first mac, what a dissapointment. The bug was partly solved with the firmware upgrade, but after that it still behaved strangely. The fans suddenly go up to maximum speed every hour, then quikcly return to normal. There still have been lockup's / beachballing with USB, and overall slow performance.Now I am running the latest mac osx Tiger version, about a few weeks ago, the fans start revving up almost to maximum, all the time, regardless of cpu load. The cpu temperature reads about 60...65 degrees centigrade when idling (minimum cpu load), cpu setting is already on "reduced speed". After switching-on, cpu temperature is already 60 degrees centigrade. The cpu heatsink is stonecold, as is the exhaust airflow. The cpu 2 fans roar like mad and keep revving up and down. When I remove the plastic transparent cover, the photocell is activated and a red LED comes on, now the fans immediately return to normal speed. Anybody else had similar problems wit the powermac G5 SP 1.8Ghz ?

Sep 17, 2009My CPU fans for proc.A are near-constantly capped at 300rpm(system minimum), no matter how damn fast the B-fans spin to compensate.I have: Kept it clean inside. Kept CPU settings on Highest, as usual, but tried Reduced/Auto Repaired permissions Reset the PRAM Reset the PMU Booted into single-user mode Reinstalled Leopard
Obtained & ran Service Diagnostic CD and passed all tests Re-calibrated the CPU's only to notice the speeds now hover around 400rpm now What more can I possibly try? I don't believe a re-seating of CPU's is in order. They work great. All my fans & temperature sensors passed their diagnostics tests, too.I am very irritated by the noise of 2/4 fans overcompensating and getting very loud, from 2000rm-4000rpm, and hey, my Mac is screwed up, and I really need to fix this.

Dec 3, 2008I've cleaned all my components except the HDD bay fans on my G5 Powermac. I've searched google about 5 pages deep and no luck. I have the service manual but it doesn't show how to remove those fans either. Anyone know of a link that shows how to remove them? I'm very good at taking stuff apart but I just can't seem to take this fan assembly apart. Maybe it's my kryptonite?

It also has the 7800gt video card.After I start it up it runs for about 15 minutes and then the display goes blank and the system fans go full out. I've tried resetting the PRAM, PMU, VRAM, all of those things...the last thing I have is the video card to test.Also the power supply was just replaced by a Apple Repair Center under extended warranty.

Apr 24, 2007I have this Power Mac G5 and every now and then it'll freeze up, the fans will go full blast, and the screen will go black. It's not even when I put a heavy load on it.I usually just hold the power button down and do a hard shut down. Does anyone know why this G5 keeps doing this? Should I re-seat the ram and GPU?

Oct 2, 2006I have a 1.8Ghz dual processor G5, 1GB Ram, 80GB HDD, with OS X 10.4.7 installed and all current updates, and today I was working on it and the fans on it slowly started speeding up, and then everything on the screen disappeared and a mesage appeared stating that a restart was required. After restarting everything seems to be working fine, but I'd like to know if this is a fluke or if I have a serious problem.

Nov 30, 2007recently my ibook keeps randomly locking up, it first started the other day when it got stuck on a blue screen at start-up eventually it came on, but kept locking up, no spinning beech ball just completely froze, i held down the power button to turn it off, i then had to wait at least ten minutes before trying to start up again, if i didn't it would get stuck on the blue screen, then something else weird happened, when i started up it came up with the mac set-up assistant similar to when you first upgrade, so i turned it off again and it went away, so i started up again this time i noticed that spotlight was indexing, despite it already doing that ages ago when i upgraded to leopard, so i thought this had something to do with it, because it kept freezing in the process, but today i turned it on, let it index and to my surprise it didn't lock up, so i went to play world of warcraft, and as soon as the login screen came up it locked up agai

Jun 29, 2008I have two problems with my PowerBook G4. It's a 1.5 GHz 15 inch model running 10.5.3.1. This problem gradually got worse - whenever I woke from sleep, it would freeze for 15 seconds to 30 seconds. Now, it's gotten to the point where it won't come out of a constant beachball whenever I open the machine. This is combined with general sluggishness and unresponsiveness during all use of the computer.2. The battery - sometimes it will randomly die and the machine will go to sleep mode. Sometimes it could be as high as 70% where it shows 70% then in a fraction of a second it goes to zero. The light on the battery shows the same - one second it could be at 4 lights, then one blinking one the next.

Feb 3, 2012My iMac randomly freezes and crashes on me. Most of the freezes occur when scrolling with my trackpad on websites with Google Chrome. I get the pinwheel and have to use the power button to turn off and on the iMac. I haven't noticed any particular connection to Flash websites or video related sites. It just seems kind of random. I've also been careful to have absolutely nothing else running and it still does not prevent it. Â
Also, from time to time the iMac will crash and go to a solid color screen. Either Blue-Gray, White or Black. It seems to be random colors. When this happens, I have to use the power button to cycle it off and back on again.Â
Some info about my iMac: Model Identifier: iMac7,1 Processor Name: Intel Core 2 Duo Processor Speed: 2 GHz Mac OSX 10.6.8Â
What could be causing this or how can I diagnose the problem? I can give more info if needed.

Mac Pro :: Randomly Freezes At Startup And Shutdown
Jun 23, 2014I have got a problem with my brand new Mac Pro. It randomly freezes at start-up and shutdown. I sometimes am able to work around the problem by turning on the monitors last or switching them off first but it does not always work and is a pain anyway. While waiting for Apple or another manufacturer to release a decently priced 4k display, I am using 2 HP 24' monitors inherited from my previous desktop.Â
One is connected via an HDMI cable (HP2405) and the other via a thunderbolt to HDMI cable with a DVI adapter (HP2448).Would I be better of using a Thunderbolt connection for both displays ? Or any other connection?
Power Mac G5 :: Overheating In Idle Mode - Fans Blow Harder
Nov 6, 2007I have a G5 dual 2gig and in idle mode it seems to a be slightly overheating as my fans start to blow harder and I get my mouse sticking I am running the latest version of Tiger with 3.5gigs of ram I did post in the IDvD, Logic Pro, and the Final cut pro forums the impact of an upgrade of 8gig of ram on my system whether my apps would run better and the system as a whole.
But I have not been able to get any feed back on this that was clear and I was asked to try here on this forum so here I am. I deeply love my G5 and what it can do I am just wondering if it is working at its most optimum I do regularly do my house keeping i.e. repairing permission and occasionally using Tech tool Pro to look over the system but nothing out of the ordinary jumps out. I have a screen shot of my activity monitor and cpu monitor but I do not know how to attach it.

Software :: GarageBand Not Respond Or Randomly Freezes
Jun 16, 2009I used to open up GarageBand 09 normally and it would take about 10-20 seconds. Now it takes a couple of minutes while it says its not responding. I don't think this is normal. Also sometimes when I am scrolling down through software instruments it randomly freezes and then shuts down unexpectedly. I have the new 13.3" 2.4ghz macbook. i have alot of free space and no files in the GB folder. I haven't touched anything regarding the system's font, new or old.

Apr 23, 2012I'm having huge issues with my 20-inch early 2008 iMac running 10.7.3. I upgraded my RAM (to 4Gb) 8 months ago and everything was running nice and easy until I upgraded to Lion. Either one of these things happen:Â My screen goes entirely grey or blue with white faded thin vertical stripes at random timesMac freezes working with any Adobe applications (mouse cursor still works but I can't click anything until I turn off and on)Mac freezes for a while and after a 30-second delay clicking and pressing buttons frantically everything goes back to normalÂ
The strangest thing is that when I play Sims 3 for example (a beast of RAM and video drainer) nothing happens. I tried almost everything from repairing permissions to re-install my memory modules. I couldn't run the hardware test.Â
Note: I live in Brazil so sending my machine to a Genius Bar is completely off the question.

Sep 10, 2014I got a new Macbook Pro Retina (mid-2014) a few weeks ago and the trackpad and screen randomly freeze even when the only thing I have open is Safari. In other words, it doesn't feel like my computer has a 2.6 GHz Processor and 8 GB 1600 Mhz Memory. My downloads folder also constantly has the loading bar under it; it goes away when I remove it from the dock and replace it, but appears again after downloading one thing.
This is really frustrating when I got a new Macbook so that I wouldn't have to deal with these types of problems. They're all issues that I never encountered with my Macbook Air (mid-2011).

MacBook Pro :: Freezes Randomly And Beeps When Coming Out Of Power Down Sleep
Jun 27, 2014So, I have a late 2011 MBP 2GH i7, OSX 10.9.3. 500GB HD 16 BG 1600 Mhz DDR3. Â
The problems started a while ago when the computer started freezing at random times. The mouse would move and there was no "pinwheel" but the computer was unresponsive. When I closed the screen the power was still on and the screen did not shut off. The only way to reset the computer was to hold the power button and do a hard reset. I don't remember if I replaced the RAM from 4BG to 8GB Crucial Memory before or after the computer started freezing, either way, shortly after or around the time when I replaced the ram the hard drive also failed.
I replaced the HD with I believe a Seagate hybrid drive with a small solid state segment. This whole time the computer is still freezing and now since I have a hybrid drive the Apple store can't support because it's not factory specs and MacMall here in Santa Monica can't find anything wrong with the hardware or software after running all of their tests.Â
At this time I have a feeling it is the ram so I purchase a new 16GB Crucial RAM. Everything is great till it yet once again freezes in the same way as before BUT!! Now if the computer sleeps because the battery run's low, when I plug it in and the computer reboots (grey opaque screen with the vertical lines as the bottom) it starts beeping 3 times. I hard reset via the power button and the computer boots up as normal (although a little slower). Â
