When start IMac screen is white with no spiral and no apple logo

Why is my Snow Leopard OSX 10.6.8 IMac screen all white when I turn it on? There is no spiral and no Apple logo and the desktop does not appear. The screen is just white.
Prior to this, we had a wind storm in our area with some power glitches today. After one of them, the dock items disappeared and just the wallpaper was there. The colored spinner began going around when I clicked on the mouse but nothing was happening. I unplugged it to try to reset it, but now the screen comes up all white, there's no apple logo that appears at start up and that's it. Now what should I do?

Hello kathy15945,

White sceen with blue dots and an apple logo

Hi. I have a iMac and when starting it up I get a white sceen with blue dots and an apple logo. Is my computer totally broken?

Sournds that way however you should take it to your local Apple Store or AASP to be professionaly diagnosed.

I'm having issues booting up my MacBook Pro. When I turn it on, I get the sound and the apple logo with the spinning wheel, then a loading bar appears, then after about 30 seconds it shuts off. Suggestions?

I believe it's OSX 10.7.5 or .4, can't check now. I'm not able to boot up past the login screen. A bar comes up below the apple logo as if it's installing an apple update, but doesn't make any progress. Eventually, the bar goes away and just the apple logo and spinning wheel are there, then it just shuts off soon after. I've tried holding shift key on power up to enter safe mode, but nothing happens. Any help/ suggestions would be greatly appreciated. Thanks!

You can't backup without booting the computer unless you remove the drive. But it may be you have a more serious hardware problem, so I think you may be better off taking it in for service.
But here's what you might try since you now have an external drive.
Repair the Hard Drive and Permissions - Lion/Mountain Lion
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair
When the recovery menu appears select Disk Utility. 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 drive's main entry (topmost one) and click on the First Aid tab, then click on the Repair Disk button. This will fix the boot block if it's damaged. Next, select your OS X volume from the list on the left (sub-entry below the drive entry,) 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 then click on the Repair Permissions button.
If you have no problems with the above, then quit DU and return to the Main Menu. Select Restart from the Apple menu. See if the computer will boot properly.
If you get this far you should backup the drive ASAP. You will need to prepare your external drive:
Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.

IMac screen gone white with small flashing question mark in centre of screen

iMac screen went blank (greyish white) on startup and now has a small question mark flashing in the middle of the screen.
Any idea what I should do?

Thank you.
Was just trying the routh of a USB keyboard & mouse and by holding down the 'option' key, the request for wireless network popped up; after connecting, 'internet support' popped up and now it's showing a small rotating globe and a horizontal hourglass with 1:23 to go still....
Let's see how this does

When booting the screen remains white with a flashing globe. What is this?

I am a new Mac user and the last two days I have seen this happen when I boot. What is the computer doing?

To fix it when the machine does boot navigate to System Preferences - Startup Disk and select the internal HD so it's highlighted then restart the machine.

Help blackberry curve 8520 screen gone white with funny icon and saying reload softwear 552

hello my blackberry curve 8520 screen has gone white and funny circle icon has come up with reload softwear 552 at bottum of screen what do i do as it wont do anything ive tried battry pull and turned back on and it still brings that up
Solved!
Go to Solution.

It seems that you have not installed the correct blackberry software for your device, or might be select the incorrect carrier for your blackberry handheld. You need to download the correct blackberry software with your service provider and before installing the software, disconnect your BB device from the computer and then install it with proper administrative privilege.
After installing the software on your computer, make sure to hard boot your blackberry handheld before connecting it to your computer. If the same problem persists, then use JVM Loder to complete wipe your blackberry device memory then connect with the desktop manager and install the software.
Good luck..!!!

Mayank

Hi , and a warm welcome to the forums!
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.
If 10.7.0 or later...
Bootup holding CMD+r, or the Option/alt key to boot from the Restore partition & use Disk Utility from there to Repair the Disk, then Repair Permissions.
And sorry to report that OSX is more Widows like than ever, but….
If that doesn't help Reinstall the OS.

Reinstall Snow Leopard 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.

Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

Sometimes when downloading a .pdf file I'm not automatically switched to Acrobat reader, but the screen becomes white with a red borderline left and upper, IE doesn't have this problem

The screen shows the borders of the original site. Beneath the Mozilla workbar the screen becomes white, on the left and upper side there appears a thin red line. Nothing is downloaded, clicking the right mouse button doesn't solve the problem. It doesn't happen everytime I try to load a .pdf file. When I go to the same site using Internet Explorer I do not encouter the same problem, swiching to Acrobat Reader or FoxIt is immediate.

To enable this right you need Acrobat, not the free Reader.
However, starting from Reader X it is possible to add simple markups to any file, unless it has been specifically disallowed by the creator of the file.

Just updated my Ipad operating system and one of my apps starts but then the screen turns white, with only the advertisment at the top showing

Just updated my Ipad operating system and one of my apps starts but then the screen turns white, with only the advertisment at the top showing

The normal suggestions.
Close the app,off fully. Double tap the home screen then touch and hold any of the icons on the task bar until they jiggle, then close them all off by touching the - sign.
Then reboot the pad and try the spp again. If same issue, delete the app, then reload it. ( no charge). You may just have a bad copy. If continues, write to the developer, they may need to do an update. I have an older version of the same app and it works fine.
Since yours is the ad supported version, they are maing real sure you see the ad. Is it as simple as you need to click thru the ad to get to the game?

What does mean when a imac screen goes all white

what does mean when a imac screen goes all white

Hopefully its not the logic board. try a PRAM reset: http://support.apple.com/kb/HT1379
basically hold cmd, option, P, and R directly after start. Keep holding them down until you hear two chimes. That indicates a successful PRAM reset. It is not uncommon to hear 3.
If that doesnt work try an SMC reset. Pull out the power cord from the back of the mac for atleast 15 seconds. plug it in again for 5 seconds and power back on ...http://support.apple.com/kb/HT3964

TS3274 My start up screen (the one with the apple) is lime green and other parts of the screen is pink. It happened suddenly.

My start up screen (the one with the apple) is lime green and all screens are pink and green. Some parts of screen still have white. It happened suddenly. What is this?

Hey there,
Thank you for your question. It sounds like you are seeing some graphical issues when you boot your iPad at the Apple logo. I had a couple of recomendations for you to try. First, reset your iPad:
Reset
You should reset your device as a last resort and only if you can't restart it.
To reset, press and hold both the Sleep/Wake and Home buttons for at least 10 seconds, until you see the Apple logo.

You can also try backing up the phone to iTunes and then restoring from that backup as well with this article to help determine if the issue is software or hardware related:

Part of my screen is white with lines?

My computer was fine a couple of days ago. I had not used it for a few days, and when i powered it up just now, a small portion of the screen is white with a few lines. It annoyingly covers a part of my screen and i hate it. I have already tried restarting my laptop many times. Help! Here is a picture of it: https://www.dropbox.com/s/w8tzp70rbzp5eap/2014-11-28%2014.28.50.jpg?dl=0

That is going to require a new screen to fix. Looks like maybe it is a dv6000? If not, please give us the full model number of the laptop. Screens now cost under $75 and are fairly easy to fix.
