Computer wont boot up past apple logo

my computer has recently stopped booting up and wont get past the gray apple logo screen unless its off for a while...however when it does it just freezes up and I start this process all over again...any suggestions?

Being that it is Lion, you have a Recovery HD that you boot into in order to run Disk Utility. Hold down cmd-r while restarting and it will boot into the Recovery HD. From there you can run Disk Utiility and repair the disk.
You should take it in to Apple again. The odds of you getting two bad drives are pretty slim and I would imagine something else is causing the problems and killing the drives. If you can make it through exams and still get it back to them under warranty, you might consider that. Make sure you point out that you had brought it in before and they replaced the drive. If this drive is also, bad, make sure they look for other problems such as the logic board.

Open iTunes on computer. Connect iPhone to computer with USB Cable. Hold both home and power buttons until iTunes recognizes iPhone in Recovery Mode. Usually takes about 20 seconds of holding both buttons. Click Restore button of iTunes.

Mac wont boot, hangs at apple logo screen

Hello everyone,
I have a 2006 Imac. This morning I tried to boot and it hung at the silver/white screen with the Apple logo and the spinning circle of lines below it. The computer will just hang at this screen.
Every time I tried to boot I can eventually hear the hard drive turn off. I recognize the sound when the computer was working and I put it to sleep it made the same sound. Anyways, it will hang on that screen for however long before I turn it off. I am no expert with macs, I tried loading the install disc but it wouldn't even load that and now I can't seem to eject the disc either. Please help!

I have been having this problem for the last several weeks on my MacBook Pro–I think a 2006 also. Mine will hang just before the Apple logo so the whole screen will be silver. Every time this happens I turn it off using the power button and just try again. Usually on the second try it works, sometimes the third. I've been experimenting with how long I hold the power button down, although it shouldn't be too sensitive to that and I don't think I am finding a correlation. I have had this occur in the past but only as flukes, not as a consistent pattern like lately. I'm getting worried that someday this thing will just not start up.

Mac won't boot up past apple logo and spinning wheel

It wasn't responding at all, so I had to hard shut off (Hold down power for 10 seconds). When I tried booting it up, this happened. So after 10 minutes, I tried to hard shut off again, and retry. Same problem. I didn't know what to do at that point. Needless to say it's now off, but when I try to turn it on, it goes to the apple logo, the wheel sins endlessly.
I just got a new hard drive and battery in January. I can't lose this because it has some VERY important information on it

ok, it MIGHT be the hard drive, but I don't know enough to be for sure. When I booted from the leopard disc, it couldn't dint my hard drive to install it on. I went to disc utility, and it did show my dvd drive, but not my hard drive. I tried booting without the disc and holding option down, and nothing happened. I tried booting holding down the s key, and a folder icon showed up that had a question mark over it.
Any advice?
I have a late 2006 2.0 intel with 512mb RAM 80 GB hard drive

Screen replacement and iphone wont turn on past apple logo help please

I broke my screen on my iPhone 5s awhile back and when i finally get to replace the screen i did and then when i go to turn on my iPhone 5s the apple logo pops up and then it apple will go away but you can see that the screen is still on. I can connect it to iTunes and it said sn # N/A and when i go to restore and update it will say i think error 9 or 6 and error 27 or 29 then is will show and blue screen on my iPhone 5s and then it will shut off.

If you have opened the iPhone yourself and did home repairs then it is not meant to help you

Computer wont boot

no changes, computer wont boot. See apple and chime, and never makes it further. Happened once, did disk utility and it has catalog is bad.... decided to do an erase / install of leopard. a few days later it did it again. So this time I ran disk utility from the install disc, and it says the catalog is messed up again. zeroed out the hard drive first. then did another install of leopard. installed all my software again, iwork, ilife, etc. Turned on the computer a week later... SAME THING AGAIN. This is ridiculous. Why does this keep happening? What can I do?

the "catalog" essentially always resides in the same area of the hard drive (at the front). It is placed
there by the OS for quick access since the leading edge area of the drive transfers data the quickest.
Most likely your drive has some bad and/or marginal sectors giving you problems in the beginning
section of your disk. In other words, your hard drive is slowly "going away".
Check your drives S.M.A.R.T. (drive) status

G5 mac wont boot up past white apple screen

My kids mac wont boot up past the white apple screen. I can here everything running but the monitor starts to get all static and scan lines with a reddish tint to it. I tried the commandoption+pr but it still wouldn't boot-up past the white apple screen. Not sure what else to do. Any help would be greatly appreciated. Thanks in advance

Hi there Peter,
Not cheap anyway you look at it sorry, professional Data Recovery being the most expensive.
Unfortunately, Disk Utility can't fix all that much, and the only other Apple Options are erasing the HD, or installing OSX to a second drive, then using Migration Assistant to move stuff over to the new HD.
If Disk Utility or fsck should fail to repair it, your best bet is DiskWarrior from Alsoft, you'll need the CD to boot from if you don't have another boot drive...

This one would require another HD with plenty of space to recover to.
You should use another Boot Disk or other Mac with this one in Target mode to do the recovery.
They have a free demo to see what it could recover.

Won't start past apple logo, won't boot from install disc

mbp penryn 2.4 core 2 duo won't boot past apple logo. Running mtn lion 10.8... inserted Snow Leopard install disc, held down C key, only get a grey screen.Recently installed new HD, (seagate 750 Hybrid), upped ram from 2x2 to 2x4. All has been running very smoothly (and much cooler) for the past 3 weeks. Then this, prompted apparently by the mac going to sleep w/o being plugged in. Ran battery down, I suppose? Happens frequently.
Any suggestions?

ds,
"You might have ruined the RAM by handling it and touching the contacts.
Once you put new good RAM into the machine, reset SMC and PRAM then boot it up."
On the odd chance that I did ruin my ram I replaced w/ 4gb brand new ram, reset SMC and PRAM, then attempted to boot. Still a grey screen. Also re-attempted to put mbp into target mode, but no luck there either, nor with ejecting the Snow Leopard install disc via option/trackpad method, both on startup and while running, and no luck there either. I have a second Penryn mbp that I could salvage for a spare part if I knew what the problem might be. So far I get the idea from your responses that my machine SHOULD be rebooting, but for some reason isn't.
If this helps:
I hear, consistently on attempting startup, fans powering up, then two short whirrs as if a drive head is moving, then when the fans quiet down after 30-45 seconds, another short but different whirr, then only quiet fans and a grey screen.
Thanks in advance for any reply.

My i mac wont boot up past the start screen

My imac wont boot up past the grey screen with the apple logo, the progress bar gets to about midway and stalls at this point.
I even left the system on in this state for the remainder of the day to no avail.
The original problem which resulted in the grey screen, was that when the system did boot up i had a black screen with only the task bar, however when the task bar tabs opened i could not get any of the options to actually operate/function. At this point i turned the system of and after the third attempt the system faltered to the grey screen.
I have tried the Safe mode boot/nram/pra/smc rests but the system still stalls midway on the progress bar, even holding the c key.
Help please....

See if the computer will boot into the Recovery Partition (Command + R on startup) if it won't that means the HD has likely crashed and the ONLY thing to do is get it serviced.

IPhone won't reboot past Apple logo.

iPhone 4 won't reboot past Apple logo. It will not show up in iTunes to perform a restore. I can't even get it to turn off. Help?

Reset phone - press both home and sleep/wake buttons until the Apple logo reappears.
If that doesn't work, try recovery:
1. Update to latest iTunes (10.3.1)
2. Connect phone to a USB port directly on the computer
3. Press both home and sleep/wake buttons until the Apple logo appears, then continue pressing the home button alone until iTunes detects the phone in Recovery mode.
4. Follow the prompts to restore.

HT1199 my computer displays grey screen and apple logo for 10 minutes or more during start up and shut down. sometimes it refuses to shut down . this issues started after installing OS lion. what do i do?

I don't think it's exactly an incomplete installation brody, but most likely in-correct permissions somewhere along the line that either happened, or became magnified during the upgrade. Also, it could be corruption as well.
First thing to do, is boot up holding down Shift key to do a safe-boot so we an clean up any corrupted OS caches, after that do another reboot, but go to the Lion recovery, and scan the HD for errors, repair any if you find them, and then try to do a Repair Permissions job.
That should fix the issue, if not, we can start doing a PRAM reset and SMC for good measure.
