PowerPC :: System Making Loud Noises / Gray Screen With The Apple Logo At Startup
Jul 12, 2006
I have a Rev A 12 inch Powerbook - 867 mHz, 640 RAM, 40 GB hard drive. The machine's always been reliable and has performed great over the years. I bought it the last week of July, 2003.
Yesterday, the Pbook was shut down, and I press the on button so it would boot up. Almost immediately, the hard drive makes a loud, whirring noise. The computer advances to the gray screen with the Apple logo, but it doesn't get past that point and the noise continues, as if it's a car engine that just won't start...
I'm going to take it to my local Apple Store in the morning, and hopefully the data, including my nearly 22 GB of music, can be saved. Any thoughts on how to get my computer working again? By the way, it's the original hard drive installed. Hopefully this is enough info to generate some ideas, I'm stumped.

So, recently (as of thursday or so) my PBG4 has been making weird buzzing noises, usually only when it was working hard (or watching things online). Eventually, as it got closer to the weekend, the noise started to get louder whenever it would come on, so I'd just turn off my computer for an hour or so and let it cool. Finally, today, I turn it off again and now whenever I turn it back on, all I get is the gray start up screen, sans spinner. Sometimes I even get a little folder with the mac face on it. What's wrong?

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.

IT does this every time, but when I do command and r or other such keyboard commands, it goes I the recovery pahe with no problem. Whenever I tried erasing the iMac to reset it, it said the disk was locked.

I have had my MacBook for almost two years and the battery had just died on me. So I sent it back to Apple and got a new one. But ever since switching over to this new battery, my computer has had issues starting up. A grey screen fades into white and the Apple logo never appears. The computer will just stay like that for hours. A friend suggested turning the power off and back on, holding apple+ctrl+P+R, which worked. However, the next time I turned my computer on, the screen stayed white again, without an Apple logo. Can you tell me what the deal is? Should I bother reporting this to Apple? Is this permanent damage I'm going to have to go thru everytime I start me laptop? Any way to fix it? Thanks.

I own an iBook G4. I could not get it to boot up, it would just go to a grey screen with the apple symbol and a timer/clock that looked like a gear.FYI: I may provide more information than necessary in the text below. I'm not sure what is and isn't relevant.
Following some advice I found in this forum I got out my old OS disks to boot from the disc instead of the hard drive. I intended to archive the old hard drive and install my latest OS (10.4.6 on the disc, 10.4.11 was the version I had been running on the machine, I believe). The machine told me it needed 4.5 Gb to install 10.4.6 Tiger, but I only had 4.0 Gb left on the hard drive. So instead, I archived and installed with the OS that came with the computer originally, 10.3.4.
I got things going, did the archive and install, and got to the log in screen. Unfortunately, I could not remember the password, so I booted up in single user mode, and entered the following to get into the machine:
1. mount -uw /
2. rm /var/db/.AppleSetupDone
3. shutdown -h now
This got me in with a new admin login, and I started up in 10.3.4. I soon noticed that I could still see all of the files that I put on the hard drive on my old operating system. I thought I shouldn't be able to see them, but since I could I decided to try to copy them to an external hard drive. When I did, I got an error message saying that there was a read/write error. I was not entirely surprised, but I decided it was time to turn back to the forums for help.
What I want to do is copy everything from my old hard drive onto an external hard drive, make room on the iBook hard drive to reinstall my latest operating system (10.4.6). Once I've done that I'd like to get the essential files back onto the iBook from the external hard drive and continue using my computer (even though it is a dinosaur).

Unfortunately I bumped the switch on the power strip that my Mac Mini (1.42ghz G4, OS X 10.3) is plugged into while it was running. Now it won't boot up. All I get is the gray screen with the gray apple logo and the spinning wheel but no OSX.

I just bought a new 27" iMac and when I start it up I get a white progress bar under the apple logo. When it does come up, iTunes will not play and sometimes the computer will not recognize the magic mouse or my WiFi. Everything works fine after I re-start.

I recently noticed the Apple logo is magenta at start up, when it is centered on the screen, before it turns gray and moves up the screen to make room for login details. I cannot replicate the issue on restart but only see it when it starts up first thing in the morning. It literally flashes up for just a second or two then normalizes to gray.

1.33 Ghz) has started acting up, and while I think I know what the problem is, I'd like some confirmation.The symptoms:
After starting the PB up, it runs for about 5 minutes before we get a permanent spinning beach ball. When the beach ball is up, I hear what sounds like (and is coming from) the hard drive. It sounds like it's spinning either way to fast, or as if something is wrong with it. All the open programs freeze, and we do a forced shut down.Also, the first time this happened, we had a song playing in iTunes. The song would play a 2 second clip, then stop, then start, and continue to stutter.
We've tried turning the computer off, unplugging the battery and the power, but it still does this.I think it's a hard drive problem, and that we need a new hard drive. Does this sound correct?

My friend's Macbook Pro (2006, 1.83ghz, upgraded to 2gb ram) has been making ridiculously loud fan noises. We found it was coming from the right fan, sounds like something is scraping - almost a tractor engine-type sound. I have a newer Macbook Pro and I installed fan control 1.2 on both of our macs to compare. It turns out on hers, the LEFT fan is running at 0rpm and the RIGHT fan (the noisy one) is running at fairly average speeds (compared to mine, which is quiet - between 1500 and 3500rpm). The temperature seems to be on par with mine (about 115-140 degrees F). We did a PMU reset, which didn't change anything. Do I need to replace BOTH fans? I have researched it, and it seems like I could replace them if I had to.

I have an Early 2008 Mac Pro 3.2 GHz dual CPU (8 Cores in total) one day I started the system as usual and the system start till the Apple Gray Logo appears and then it reboots and keep doing this in (loop)
I started the Apple Hardware Diagnose and it hangs in the middle! the Apple Authorized shop/repair people told me (after the tried to fix it) it is mostly the Logic Board
Can it be the RAM or the CPUs? my mac is out of warranty and the cost to fix it is crazy! so I was thinking I can buy the parts and replace it my self.

So, today I tried to install windows through boot camp assistant on my mac. When it got to partitioning my drive I got an error that my hard drive needed repairing. So I opened up disk utility and clicked verify disk (I can't click repair) and got this error Disk Utility stopped verifying �Chris Hard Drive� because the following error was encountered: Filesystem verify or repair failed. I then researched this and learned to fix the problem I must boot from my leopard install disk and use the DU from their. Unfortunately I don't have access to the disk. But I have the install disk from my old macbook (the white one) so I used this. I put in the disk and shut down. When I turn it on I hold C but all I get is a grey screen but with out the apple logo. When I try turning it out holding alt I don't get the option of the CD just Chris Hard Drive. But when I boot up holding D i do get to the hardware test screen but I get the error that's something like "Hardware test does not support this hardware". Will the Leopard install of a different type of macbook not work on my new macbook pro (13" aluminium)?

I'm noticing some weird behavior in my Mac Pro first gen.
Basically, when I start it up, the displays just stays black for some time, until the Desktop loads up and the computer is functional, but never displays the gray screen with the Apple logo. This just happened all of a sudden and stayed like this.
I know is not a big deal now, but I'd like to sell it in the near future and this could be problematic for that.

This morning, I would turn it on and it'd go to the grey screen with the Apple logo for a few seconds and then go to the icon that is a circle with a line through it. After reading online, I was able to boot it up in Safe Mode. I went to Startup Disk in Preferences. I chose the MAC OS X, xxxx and then clicked the lock to prevent further changes and then clicked restart. Now when I turn on the macbook, it goes to the grey screen with the Apple logo for at least two-three minutes and then just shuts off. Won't boot into Safe Mode now. I already tried the Command-Option-P-R keys trick like five times.

I just bought an iMac G5 off ebay and today I tried to use the Tiger install dvd because the previous owner had deleted software like textedit, etc.
Anyway, I put the disc in and clicked on Install Mac OS X, then clicking restart. once the iMac shuts down and begins to restart, as it is on the grey screen you can hear the disc being read, then as the background goes a different shade of grey and the Apple logo appears, a minute or so passes and then the iMac begins making a lot of noise. I went away for 10 minutes, came back and it was still doing the same thing.
So I'm basically looking for help because I really want to erase and reinstall everything.

For several weeks, my black MacBook (2008) has been acting odd. Certain applications won't open, and when I attempt to open them, the computer makes a quiet clicking noise, like the drive is failing. Last week, when trying to boot it, the thing just wouldn't. Stuck on the grey Apple logo screen. Assuming a hard drive problem or failure, I ran the tests. I ran Disk Utility from the Snow Leopard install disk, checked & repaired permissions, checked & repaired disk. All okay. I ran the Apple Hardware Test from the install disk that came with the computer, using the test that runs for an hour or so, and all appears to be fine. The computer won't boot into safe mode. I've tried flashing the PRAM. I doubt I could achieve much through target disk mode, as I've already run Disk Utility. What's left to do? Something doesn't add up here.

My Macbook Pro is not starting past the grey screen and the apple logo and the rolling circle. I have tried every method and I am desperate to do anything to start my computer even erase the entire disc. I have contacted the Apple store and they told me the cost will be equivalent to $600 to just repair it and no way I will be able to afford it. I am willing to do anything and even erase my entire disc. However, for that the instructions on the Apple page state that 'Insert your Mac OS X 10.4 or 10.5 installation disc'. However, I do not have my installation disc Is there any other way I can erase the OS system and at least reboot my Macbook?

Macbook Air, Rev A. Worked like a charm for 1.5 years.Upgraded to a Rev c SSD and gave the Rev A to the wife.She installed NOTHING.Within a few weeks it started running VERY slow. I'm talking 2 minutes of beach ball per click.I use Disk Utility to check the drive. No problems of any kind.
Rebooting would take -- and I'm not exaggerating -- over an hour. First it would sit with a grey screen for 5 minutes. Then with an apple logo for 10 more. Then with the little spinning circle for 30. Then the desktop background would show up and sit for 20 minutes, etc.
Was gonna upgrade to Snow Leopard so what the heck, backed it all up and installed Snow Leopard. To my surprise, it instaled Snow Leopard on top of the old OS -- it kept all the files around so no need to restore from backup.
Speed problem SOLVED!Then a few weeks later the same problems.This time I check the drive AND run the hardware test. No problems.I ERASED the entire drive. I installed Snow Leopard.All is good for a few weeks.Then the problem came back a 3rd time.
I go to reinstall a 3rd time and Snow Leopard doesn't even acknowledge that there's a hard drive in the machine! And when I look in system profiler it says there's no drive of any sort. Yet it will reboot and run... just VERRRRRYYYY slowly.
I'm ready to replace the drive with a Runcore SSD or some such other device but I want to be sure the problem is the drive and not some other aspect of the hardware (motherboard, RAM, etc.)Anyone ever seen this? Anyone have any ideas as to how to investigate, solve, conquer, save myself from madness??

I have a MacBook Pro from 2010 I believe with iOS Maverick installed. (MacKeeper is also on there, which I just found out is apparently malware)Â
So three days ago I was watching Netflix, the image froze, but the audio kept going. Figured my internet was slow, so I waited a little, nothing happened. pressed escape to leave the full screen mode, but nothing happened. None of the keys would do anything, not even the sound or brightness keys. So I did a force shut down by holding down the power button.Â
I waited a little, then decided to turn it back on. Start up sound played, white screen with grey apple logo and loading gear appeared together with a grey loading bar. I figured that this meant it had to repair something. But after about a minute or two it just went to a black screen/ shut down. I left it off for a day, tried it again, same thing. Next day I tried booting it up while holding the shift key to do the safe boot (I knew it wouldn't work since I already had the grey loading bar anyways), same thing happened.Â

I am looking at purchasing an Ibook G4 but the description of the item includes this:"When you switch it on it begins to load up i.e. the blue screen with the Apple logo, but then the screen goes black or flickers. Said friend has kindly wiped the hard drive for me so now when you switch it on it makes the �opening� noise then you get a blue screen with alternating �?� and the Finder logo."
I have a feeling this may have been a temporary fault with the screen connector being loose and possibly damaged.But i assume the alternating "?" and the "finder logo" is simply a lack of OS?
