Power Mac :: G5 Won't Start Up Correctly / What To Do?
Dec 10, 2007
I will start up my G5 and I hear the chime but at that point my CRD monitors never come on. The lights on my USB hub don't light up, either. Then my G5 fans rev up really high. I have to hold down the power button to get it to shut off, then after waiting around 10 seconds I'll try to turn it on again. After several times of repeating this process, my monitors finally kick on, the USB hub lights up and all is fine for the rest of the day. But it's really aggravating having to do this up to five times to get things going. It's like the G5 isn't communicating to the monitors or the USB hub.
Could this be a motherboard issue? It shouldn't be a power issue, as the only thing plugged into my battery backup APC is the tower itself. I'm at a loss here...

I'm planning on giving my brother my early 2008 aluminium iMac but he lives in Canada; I live in the UK. I read somewhere that iMacs have a voltage recognition ability... is that true? If he buys the equivalent North American power cord, will it work correctly?

Ok, I know I've had 2 discussions here already but it still doesn't make sense to me. Everything says its a bad Logic Board. Ok, Power Mac A1074 2.0 DP It hangs at white screen w/ grey apple logo and no spinning wheel. I have ran the Apple hardware diagnostics disc several tims. Everything comes back that all hard ware is GOOD. I try and run the OS diagnostics on the same disc and it hangs at the white screen/grey apple logo. I have replaced the hard drive and started it holding 'option"it reads the Apple OS Install disc (just as it reads the hardware diagnostic disc just fine) when I try to boot from the install disc it again hangs at the white screen/grey apple logo with no spinning wheel.

I have a 1.8GHz G5 that will just not boot up. When I start it I get the grey screen with the Apple logo and nothing else. The fan then fires up and up. Have tried starting it in Safeboot mode. In this mode I can hear the initial chime and some activity for about 5-6 secs and then nothing. I have an extra 2GB of Kingston RAM in the machine that I put in a couple of years ago and apart from this nothing has changed apart from upgrading the OS's.

It was checked with another power cord too, no power at all. The battery has been replaced, still no luck. Who can repair it? I called a guy, he said to change the logic board that "could be" the problem is too expensive. Advice: donate to Salvation army......Nice, right.? I love this machine, even I have a brand new iMac, iPad, PowerBook, u name it! but it runs the Classic and I have all my files written by this op.. System.

I have a G5 dual processor ((I think its a 2.5) running Tiger. I had it stored for several months and when I brought it out it won't start.. No response at all to pushing button..
Cord is good as it will power my display.

I received a semi working powerMac G4 Cube from a freecycle community, and while initially it worked fine, I had to dissemble the unit to replace the dvd drive which had a dvd stuck in it. I used one from a second unit that I was also given and I think the dvd is also bad , as placing the 'software installer', which I presume is OS9, causes dvd unit to make what sounds like spinning noise ( Does not sound to me like its reading anything ), and then after a few seconds it spits it right back out, and this happens everytime.Before I dissembled the unit, the cube at least booted into OS9 just fine, yet I am sure I put everything back properly. I might have chosen a bad setting in system perferences I suppose, and if so is there a fix short of getting a new dvd unit so I can reinstall OS 9 ? Also, I did try 'control' while startup, and it takes me to a very odd screen, with a icon for 'reload' ( browser icon similarity ) , or what looks like a right arrow. Choosing either does nothing, short of showing what looks like a watch moving in circular fashion.

My G5 has been making more noise at start up. It sounds like one of the fans is making a grinding "rrrrrrhhhh" noise. My living space if very cold and quite dusty (warehouse). I notice it more on colder mornings ( inside temp 45° - 65°F ). Should I refrain from using my machine on cold mornings/nights until the heat is running?

I've got a strange issue with my PowerMac dual 1.8GhZ and I can't figure out where it's coming from.Last Saturday I experienced a Kernell Panic while using Safari and the Dictionary (MacOS 10.5.1).Since then, whenever I try to start my computer, it shuts itself down while the grey screen with the Apple logo is on screen. However, this isn't always the case:I can use my computer 'normally' if I press the option key at start-up and manually choose my startup disk.
I can boot from a Panther or Tiger installation disk, but not Leopard.If I try the hardware test the computer shuts itself down in the middle of the test.TechTool works and didn't find any issues with my computer. Nor did Disk Utility.I tried to erase both my internal hard-drives and do a clean install of Tiger, but the problem is still there (I have to press option at startup).I tried to reset the PRAM and Cuda/PMA. Doesn't resolve the issue.When I tick 'Restart automatically after power failure' in Energy Saver my Mac will indeed restart, meaning it thinks there was a power failure.Any idea what it might be? And why it only happens in certain situations?Do you think it's a hardware or a software issue?

When I start my computer up in the morning everything else starts normally. First the light comes on on the front of the computer and on the bottom of the monitor, then the start up tone rings and the computer is fully running. But my monitor is black and I do not get the apple picture or nothing on the screen. I thought my monitor was going out, but we have another work station the same and I switched the monitors (same 27" cinema screen as mine). I can actually use the other computer and network into my computer and fully use everything on my computer. But my monitor is black (no display)! I have contacted MAC and have reset the PMU button many times and sometimes this works, but most of the time it does not. I just keep restarting the computer and finally it will start up normally with the display and everything.

I am the original owner of a Power mac G5 dual 2.0 I purchased this machine in april of 2004 and it has been working nearly non stop ever since. Recently I put it into sleep mode and when I came back it had powered down and would not start up. I assume it's the power supply and I would like to know if there is anyway to tell what type of power supply and model thereof without tearing down the machine.

I have a big problem. For some months now I haven't been able to start up my Mac. It's a Mac PowerBook G4 bought back in 2002. It's a laptop. When I push the start button it shows me the grey screen with an apple. Then the screen turns blue showing the white and square icon with an apple, Mac OSX and the line for loading saying "starting Mac OS X..." When the loading sign is complete or almost complete it stops. Nothing more happens. It just stands there the blue screen with the loading line that looks pretty complete. What can be wrong? Some time ago I was asked the message: if I want to use the new way of starting up my computer, and I clicked YES, because I thought it was the normal software updating. And eversine then it hasn't been able to finish starting up. Can anyone give me suggestions of what to do? Or maybe tell me what is wrong? Maybe it has something to do with the "new starting up" message I said yes to, or maybe not.
I really hope someone out there can give me some advice, because now I haven't been able to use my Mac for months!

I have a G5 dual pro 2Ghz (June 2004), 1.5 Gb ram, Leopard
When I press the start button, the dvd drive spins, the startup disk "sparkles" (noise seems normal) but no image appears on screen (black monitor enabled), no start-music. It starts correctly after + / - 15 attempts ignition-extinction.
The various reset (pram, motherboard) have been tempted. "Cleaning" the computer with Onyx (maintenance). Battery voltage Bios = OK. The authorization of repairs were made. Repairing minor problems in head volume repaired (the install cd has booted). Tempted to start with a minimum of devices. The symptoms still persist for 2 to 3 weeks.
I have installed a new hard drive. I've installed Leopard on it.
But the problems stay. My mac starts when he wants...

Tried to wake my 24" white iMac from sleep yesterday and discovered that it was off. Pressed the button in back but no go. Unplugged and replugged, pressed the button and it fired up fine. Surfed a bit, then put it back to sleep.
Came back about 3 hours later and it was off again. Unplugged and replugged, pressed the button and nothing. Tried it a couple more times just to check, and no go.
Any ideas? I've had this computer for a little over two years. Bought it used and bought Applecare which expired on.... Nov. 16th. Beautiful timing or what.

I have a G5 Dual 2.5 and the power light on the front (white) is lit but nothing happens when I press the power button. I was trying to reset the PRAM manually by pulling the battery and inplugging the unit because my startup shortcut keys were not working. I had seen it recommended to reset it by pulling the battery and reinstalling in other threads. I put the battery back after about 15 sec and plugged in back in. Now it wont start up.

Powermac G4 MDD Originally had 2 hard drives -- 60GB (jumpered as master) and 40GB (jumpered as slave)
The 40 GB failed and the 60 GB was diagnosed as failing so I purchased used Seagate 160 GB ATA/100 Hard driveÂ
I installed the new 160 GB Hard drive in place of the 40 GB HD and used SuperDuper to clone the still working 60 GB drive. The files were all copied to the drive and the drive showed up on the desktop as a hard drive icon, and it was recognized in the System Profiler. However, I could not select it as the startup drive from the System Prefs window.Â
I then took out the 60GB drive and replaced it with the 160 GB drive jumpered as cable select and now the computer won't start up (flashing question mark).Â

Only an issue in OS.X not OS.9. Pulling the power cord eliminates issue for next start but not subsequent starts. Pulling the cord isn't easy how the computer etc is set up so I'd like to rectify the issue.

I still have a couple of OLD apps that require System 9. When I attempt to open either of them I get the "Classic is starting" progress bar, but it never quite finishes. I can start Classic okay with extensions off but then I can't use the printer, and my old copy of Photoshop Elements won't load no matter what I try. I get an error message when I try to run "Install Applications and Classic Support" from my installation disk. I really don't want to part with the $$ for System 10.4 AND two new pieces of software right now.

I recently purchased a 30" apple monitor to be used in tandem with my 23" cinema monitor. The card that was shipped with my G5 twin 2.5 GZ will not support the 30" as it lacks dual link dvi. Hence the 9600 pro for Mac & PC card. The problem is this...The screens light up at start up but the computer crashes before the boot sequence completes. I took the card to the apple service center where I bought it and it worked fine on both their G4 and G5 machines running Tiger. I cant make it work on mine in Tiger or Leopard.

I'm currently out of the country doing field research and just the other night, there was a power outage here and now my ibook won't start up. Of course, being in a "third world" country, I wasn't able to invest in a good power surage protector.
Is my computer dead for good?
I have a lot of work that needs to be done and my computer is essential here. Anyway, I can rescue my computer? I press the power button and it does absolutely nothing.
What do you people think might be the problem and how much am I looking at to fix this?

I have an iBook g4 that is just totally messed up. The menu bar at the top does not show up except for the right side(sound,clock,power). Also, whenever I click on an application on the dock the icon reacts, but never starts the application.
I wish I could give more information as relates to the specs, but I can't access any services.

Three days ago, I stored my ibook in my bag, but I forget to take it out. (normally it is sitting on desk recharging)
The ibook itself was in sleep mode (by simply closing the lid). The battery indicator was 1/2 full.
Today I tried to continue working with it. Opened the lid, but the ibook didn't turned itself on. The sleep led wasn't pulsating either. I just thought that it might run out of juice. First I pressed the Power button. Nothing happened.
I plugged it in the power adaptor and then pressed the power button. Nothing happened. I tried holding the Powerbutton in order to force a reset. Nothing happens.
I unplugged the ibook from the power adaptor, and tried to reseat the battery. Opened the lock, pulled it out, pushed it back in, closed the lock)Pushing and/or holding the power button did nothing.
I tried starting the ibook without the battery (does this even work?), while only the power adaptor is plugged in. Pushing and holding the power button did nothing.
To sum it up: It doesn't start with and without the battery nor with the power adaptor.
The strange thing is that the battery is charging. (the light on the power adaptor plug is oragne) Three of the four battery leds on the underside are "on" while I am writing this post. Resetting the power manager (ctrl + option + shift + power) didn't do anything.

This morning when the power button is pushed, nothing happens at all. The button does not light up. The computer does not start.I checked the power cable. I took it out of the computer and put it back in. (I did note that the plug looks a bit darkened but it does not smell burnt.) I tried it in a different outlet. Same thing. It won't turn on.I can't recall if this iMac is a G3 or G4 and I can't find my documentation to let you know. But I don't know that it matters which G it is. It is the old special edition grey iMac and has been working for us for many years.Is this the end for this iMac? Could it be something that is simple to fix?Â
