Macbook-After start up sound white screen persists!!!!!!!

Help is urgently required. My macbook began to operate a little slow, e.g. spinning rainbow whenever I tried to operate anything. As a result I held power button to turn the computer off but when I tried to turn it back on (after the usual start up tone sounds) all I get is a white screen. I've tried inserting the start-up disc and holding down 'C' but nothing happens for at least a minute or two (as if the keyboard isn't functioning, e.g. cannot turn caps button on) after which CD spits out again.
Help???!!!

HI,
*"I've tried inserting the start-up disc and holding down 'C' but nothing happens for at least a minute or two (as if the keyboard isn't functioning, e.g. cannot turn caps button on) after which CD spits out again."*
Try booting in Safe Mode
What is Safe Mode
*"(as if the keyboard isn't functioning,"*
Try resetting the SMC

Thank you for your support.

You need to take it in for service, it may be a stuck key or component failure.

Why won't my MacBook Pro start up? White screen and flashing question mark.

Hi,
I've had my MacBook Pro for almost 2 years now and I installed OS X 10.8 about 4 months ago.
Today I turned the MacBook Pro on and a white screen with a flashing question mark appeared. I tried then getting the startup manager up: turning on the laptop and immediately holding in alt (option). But nothing appeared for about 25 seconds until a rotating Earth labelled 'Internet recovery' appeared that gave me options to join wireless connections. However, my internet wasn't in the options and when I tried typing in the information required to join my internet the laptop would just load and never find it.
I then tried putting in my Mac OS X install DVD (10.6.7) and help in C until the apple logo appeared on the screen and the little rotating loading circle appeared. That then disappeared and a cicle with a cross through it appeared (similar to a no entry sign). Then after about 30 seconds a blue screen followed by a grey screen appeared until eventually the disc ran properly. I then went into Disk Utility but there was no option called Macintosh HD, only the discs content. It wouldn't let me first aid, erase or repair anything.
I'm totally stumped and have 4 exams at university within the next 2 weeks. I'd really appreciate it if anyone could help me out here?
Thanks,
Best wishes,
Connor

The support article linked below is somewhat outdated. Where it refers to starting up from an installation disc, you should instead start up in Recovery by holding down the key combination command-R at the chime. Release the keys when you see a gray screen with a spinning dial.
If you don't have a current backup of all the data on the startup volume, and you want to preserve that data, then you must try to back up before you do anything else. Ask for instructions if you need them.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to reinstall OS X from Recovery, if necessary. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.

My MacBook Pro starts with a Gray Screen and Apple Logo, a bar comes at the bottom, but after few seconds the machine shuts down. This was bought approx 1 year back. Please help!!

jayanta.ray,
which model MacBook Pro do you have (did you buy it new?), and which version of OS X is installed on it?

Restarted my MacBook Air, just have a white screen with apple . Will not start up

What version MacBook Air do you have? Usually identified by the year you bought it, i.e. mid-year 2012, 2011, etc. Also, what OSX are you running? (please provide OSX ver number, i.e. 10.8.2 for latest Mountain Lion, etc.)
Not sure I can help you directly but for others to lend a hand, they'll need to know this information to make a sound suggestion. I see you're new to posting here so this will help you in the future.
Good luck.

Hi..
Your profile indicates you are running Lion v10.7 so you need to use Lion Recovery to repair the startup disk if necessary or reinstall Mac OS X.

You should be able to turn off your MBP by pressing the power button down continously for about 5-10 sec. When you reboot it you are going to want to enter into a terminal screen. Hopefully the following YouTube video helps: http://www.youtube.com/watch?v=qKOX72xNmbo

Nokia N70 starts with a white Screen.

Hi all,
My nokia N70 starts with a white Screen and does not go any further. It does not make any sound while starting. When i connect it to the PC it is not detected by the PC while the phone is on showing a white screen. I have tried performing a Hard reset using the *3 and the green key but it is not formatting either. I also tried updating the software but as the PC is not recognising the mobile connection the updater is not working either. I am using the latest PC suite.
Please help...

Remove the battery for at least 5 minutes and then replace and see if that makes any difference. Also try removing the memory card.
If the above two don't work then try these.Always remember to backup your phone before performing resets as your data may be lost.
First try these
*#7780# - Restore factory settings - resets all the settings to the default
*#7370# - Reformat your phone
If still not working
Then try the "3 finger deep reset". With the phone powered off, depress and hold these three keys simultaneously "*" "3" "green phone" and then power on phone using the on/off button whilst keeping the three keys depressed until you hear start-up tone.
This should ONLY be done if the device doesn't power up normally anymore and it wipes everything in the Phone memory that is not part of the ROM.

You are using Snow Leopard so you have no OPTION+R shortcut. You need to boot the computer from your Snow Leopard DVD or USB flash drive.
Reinstall OS X without erasing the drive
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

White Screen Persists

It seems I have tried every avenue short of removing the RAM from the computer, and continue to get a white screen. I can even get an image using the OPTION and C key method to access the INSTALL disc.
I have started up with
C key
Option Key
Shift Key
Command Option Shift Key
Command Option P and R Key
Only the Option key action prompts a password to access, but after that nothing, continued white screen.
All peripherals have been removed, I have also removed all cables for about 10 minutes, and restarted. Nothing.
Any ideas? DId I miss anything?
Thanks in advance, Teejay

Need to add that I finally got to be able to run the Disk Utility off the install disc. It says that there are no problems, so, I re-installed my software and the computer screen was working as it should. After re-install, it restarted back to a white screen. Could this be a RAM issue?
Thanks in advance!

Try connecting the iPod Touch to your computer and restore it. http://support.apple.com/kb/HT1414

Try starting your iMac with the original DVD that came with the machine then launch disk utility to repair your hard drive.

Start up remains white screen

During start-up, only white screen with Apple logo...what's happening??!

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
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.”
b. 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.
c. 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 either of the techniques in Steps 1b and 1c 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 you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
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, or if a firmware password is set, or if the startup volume is a Fusion Drive or 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 10. 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
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 10
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 11
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 12
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.
