Start up freeze on white screen

My Macbook Pro 15' 2011 Starts up with the Apple logo then after freezes on a white screen. Before it was starting up then freezing in black screen, I restarted the NVRAM and then the computer was working fine and then after a week it froze and heated up in the middle of using it so I shut it down and ever since then it has been starting up with the Apple logo then freezing on a white screen.
I have tried with no success:
- SMC reset
- Start holding Shift down - grey loading bar for about 5 mins then freezed on blue screen
- again NVRAM reset
Please help!
Thanks

Your profile indicates your Mac has v10.8 installed.
Restart your Mac while holding down the Command + R keys.
You should be able to access OS X Recovery where you can repair the startup disk if necessary, or reinstall OS X.

I do hope you have recent backup, because it look like your hard disk is failing. You can start up in Recovery Mode, and run Disk Utility to see if the disk can be fixed: OS X: About OS X Recovery - Apple Support

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

During upgrade screen freezes in white screen

during install of Yosemite my iMac freezes in white screen.

Have you searched for iMac freeze:
http://www.macworld.com/news/2007/11/07/imacfreeze/index.php
There is a known issue that effects some iMacs. Mine worked fine under 10.4 until I added iMac Software Update 1.1 through auto-update. I rolled back to 1.0 and my Mac worked fine again. When I upgraded to 10.5 my system would frequently freeze again.
I took it to Apple, they kept it for 2 days, and then they decided to replace the system entirely with a new iMac. I know of no fix, short of returning the system to Apple.

Got a iMac upon start up it has white screen with apple logo and loading wheel spinning forever under it, does anybody know how to fix this?

PLEASE HELP!!!!!! EMERGENCY Upon start up normal start up noise occurs, then after white screen with Grey Apple logo, and a spinning loading wheel under it (thee repetitive lines NOT rainbow one) ?!? then thats as far as it goes it stays on that screen forever will not boot up. Any info on how to possibly fix? I've tried several of the Start up shortcuts , it wont even start up in Safe Mode . My fiance' is crushed she is a writer and EVERYTHING SHE HAS WORKED ON is somewhere on that hard drive. Any thoughts, i'm open to any and all LOGICAL responses, thank you very much for ya'lls time ........Its just heartbreaking to see my iMac in this vegistated coma,The whole reason i bought a mac was cause I love them I have Apple EVERYTHING, so once again please help.

Try this: Switch off your iMac wait 10-15 seconds hold down the Option Key (alt) key then press the power botton but keep the option key down. This should show all the available options to boot from. I trust you have a full backup, Good luck.

Start up stucked in white screen w/ apple & scrolling cursor.

Start up stucked in a white screen w/ apple logo & continous scrolling cursor. After just pretty much staying that way, display would intermittently go off for a bit then startups & does the same behavior over again. 2008 13" MacBook Pro on OS X 10.5.8 (Leopard). Tried some basic troubleshooting i've read from blogs but noo luck! Except for the 'Force Shut Down & just holding Power button while removing battery' option... does this have bearing in my case? Thanks!

Start up in a White Screen

This morning I tried to use my iMac and it was frozen, I rebooted it and when it was turning on I got a white screen with a flashing folder with a question mark in the middle. Does anyone know what this means? I am freaking out!!!!

Hi! The flashing ? mark means the computer cannot see a valid startup OS and often means that the system is heavily damaged or the hard drive os dead or the logic board is toast. Most likely it is the hard drive that is having problems. Try starting from the install disc, right after the language screen use the drop down menus to locate the disk utility and try repairing the disk from there. If that fails you have more serious problems. Now is a good time to have a bootable backup of your entire system? Tom

IMac Freezes at white screen during startup

Hello,
I was off of my iMac for an hour or two so my screen saver when on. I went to wake the computer and it was frozen. I tried using the keyboard and mouse to wake up the computer from the screen saver, but it would not work, so I powered the iMac down manually from the button on the back. I let it sit for 15 minutes, then I tried to start the computer up again. Now at start up, I get to a blank white screen with the spinning moving pin wheel, and that is it. Any suggestions?

You could try to use SafeBoot mode on startup, essentially you'd hold the Shift
key down on startup, perhaps you may need to login after waiting quite awhile,
then continue holding the shift key down until you see a traditional desktop.
And then use Disk Utility to verify HDD, & repair disk permissions.+ Restart.
Or if you have a system install-restore DVD, boot from that and have the
Installer's version of Disk Utility check verify repair the hard disk drive.
It can also repair disk permissions, too, from the booted version of D.U.
Then when it is done, choose the startup disk from installer menu options.
The DVD should eject, but if not, it should be ignored as a boot volume
after you've chosen the Mac HD as a boot system.
PS: If your computer is now running a system later than Snow Leopard,
where no DVD would be needed if it has a Recovery partition in the HDD
then you could see about booting into Recovery (command + R) to access
the later system's OS X Utilities, and choose Disk Utility to check/repair, etc.
These may help.
Good luck!

3 GS freezes to white screen occasionally after hitting home button. Has anyone ever experienced this?

Has anyone ever experienced a white screen that freezes then turns black after hitting the home button?

I have had intermittent white screens for some time (as in three years). It happens when the phone "wakes up". I hae lost calls that I could not answer because the screen was white. It has come up white when I hit the home screen. Not always, but with random frequency. All I have to do it hit the power button (I do not have to power off, just hit the button) and reopen the phone and it is gone. I know the phone is functioning under this screen, I just cannot do anything.
My first 3GS had the problem so severly I called Apple. After two and a half hours of resets of various kinds, they decided the phone was bad and sent my a replacement. It was better, but it still has the issue. I have gotteb used to it and am waiting until I can get an upgrade to the phone in the hopes it takes care of it. In the meantime, I occasionally doa search here and un the intertubes to see if someone else has the issue and a solution.
My suspicion has been that some app I downloaded causes it, but I have deleted apps and cannot get rid of the issue.

Mac sometimes freezes to white screen out of nowhere?

I have a MacBook Pro late 2011 running on Lion. Out of nowhere the screen just turns white and item it will turn a grayish color and get really hot. I am out of the warranty, and I have no clue how to fix it. I can get it to turn on occasionally, as I have been trying to get files off of it, but then it will freeze and go to the white screen in no more than an hour.
