Screen goes blue and then goes back to login mode

This is happening on a couple of imacs in our department. It's happening a couple of times a day just randomly.
any suggestions? I searched other posts to see if I could find an answer.
Thanks

Hello Amin Najib Zadeh,
Because you have tried multiple times restarting your iPad with it still going to a blue screen, then check out the article below to restore your iPad. Make sure to set it up as a new device and test it out.

Screen switches to blue and then fades back to normal repeatedly

My Mac Pro's screens have started switching to blue and then fading back to show the normal screen contents. Each cycle takes a couple seconds and looks like my Mac thinks it's waking up from sleep. It starts off happening a few times a minute and gets faster until it's happening once every 5 seconds or so. The mouse goes unresponsive just before it switches to blue and then comes back to life when the blue fades out. Interestingly this has been occurring every morning since I started using Snow Leopard; once I shutdown and start back up again it's fine (until the next morning). No messages in the console to indicate what's going on.
Has anybody seen this or do you by chance know what's happening? I power off the monitors at night but leave the system on (not sleeping), so it's interesting that it seems to happen every morning, about 15-30 minutes after I start using it.
Thanks,
Adam

Nah, I'm on latest Snow Leopard version. I think the issue is actually RAM as I installed 8gb worth on top of the 4gb I already have in the Mac Pro at teh weekend. Rise B was not seated right at first so I had to open it up and re-seat it - it then showed all 12gb
I've just had a look and it's showing Riser B as empty for some reason again!! I know it's not the memory itself but for some reason this whole board does not want to go back in properly - grr!!
Will try again in a mo and see if it makes a difference
As it happens while i get the same result as you do with the blue blinking I have a few minutes in between each fade to blue and back again! AND it closes all applications at same time too!

Itpod touch screen turns blue and then white and wont turn on

all of a sudden my screen went white and then blue and unable to turn on my ipod touch.Tried again and it started going black and red vertically . then the screen stays blue. have tried to restore 3 times know. nothing has worked?what wlse should i do.

start up from the System DVD and use the disk utility app from the utilities menu at top of screen before the system installation. Repair the disk and permissions (will only repair permissions for Apple software, not third party, but it'll address the system components which may need it)
If that doesn't fix it, then boot up from the DVD again and this time reinstall the System software (be sure to check the options to keep user so you don't overwrite all your personal data).
Another option is to restore your entire system from a time machine backup that was made when your computer was working fine (ie: the day before this started). Problem eradicated.
This assumes you have an external hard drive set as backup disc and are using time machine. If you aren't, you should be.
Also, for the moment, remove all items from the auto- startup-at-login list in accounts prefs.
Also remove all hardware peripheral devices except the power supply and assess whether the issue still exists when nothing extra is plugged in. Temporarily turn off the airport card and bluetooth too for the same test. If no change when all these things are disconnected or turned off, then you will have narrowed down the issue considerably and reinstalling the system software will probably do the trick

When I get to the login page on my macbook, I type in my password and it starts to load, but then the screen turns blue and it goes back to the login. What should I do?

I was having some problems with my mac, safari and itunes was freezing alot. I have to force shutdown and when I tried to start up again i get to the login page, type in my password and it starts to load, but then the screen turns blue for a few seconds and it goes back to the log in screen. What should I do?
Please Help!!

Somewhat similar problem:
Put in the password, hit enter, the screen goes blue for half a second, then goes back to login screen and carries on logging in as usual. Drives me mad. It doesn't happen with a fresh Lion installation, nor if booted into safe mode. On the machine in question it also happens to new user accounts.
I've removed all login items, including Startup Items and Launch Demons (pun intended) and Agents, I've compared system login plists with a fresh Lion installation - can't see differences. I've removed Little Snitch and PeerGuardian (no more third party kexts).
@Carolyn: I've done disk maintenance with DiskUtility and fsck and even DiskWarrior, cleaned caches, etc. etc.
Any ideas would be gratefully received.
Sorry for trying to hijack the thread (as it's not about Lion), but it seemed dead anyway.

Iv tryed this numerious times still keeps going back to pasword. Can not get any further. Tried restart holding shift key.. still nothing. What do i do?

Thank you for your help.
I couldnt get to the hard drive/ desktop. Soft login not even working. So i could not do any of that.
In the end i took it to Apple and its actually the hard drive on its way out. A common issue with that series of Mac. Funny seeing i dont use this mac much. However being 2.5 years old and out of warrently, Apple have recognise this issue with this series/ Model and installing a new hard drive at no cost.
Very luck and greatful. And not feeling so dumb that it was something i did or could troubleshoot myself.
Hope this helps others that it just might be your hard drive failing.

Make sure your Mac's software is up to date.
Click your Apple menu  top right in your screen.
From the drop down menu click Software Update.

When I open my Macbook pro- the screen lights up and then goes black- keybook stays backlite- can not get screen to come back on. Must reboot-
thoughts-?? Macbook is 6 months old and on second hard drive ( failure after 45 days).

Hey! exact same thing happens to me... I use the keyboard shortcut to turn off the screen which is ctrl - shift - eject button. Then just poke a key and it wakes up again fine, it doesn't fix the problem but at elast you don't have to reboot. x

Priscilla,
if your Mac is still in warranty, then you should contact the Argentinian technical support service. If it is out of warranty, then we can try to lend a hand. (We’re just fellow Apple product users here.)

Hello kidmango,
I am going to have to agree with planb77. Look into other drivers in your computer causing the issue, not just the nano's drivers.
It is possible that security software is the culprit. Use this:
iTunes: Troubleshooting security software issues
You may have to restore your computer to a previous point. From before the issue started. Contact computer manufacture or Windows for steps, or do a search with a search engine.
I would test the ipod on a known good computer to see if its the ipod is the issue. My gut says no. You can set a reservation at an Apple Retail Store. Apple.com/retail .You can also test a known good ipod on your computer.
Hope this helps.

Google seems to change their login security occasionally, and apps that assume it will work a particular way get left out in the cold till they are updated, since the login process is hard-coded into the app.
Here is the automated e-mail I received today from Google when tried to upload a movie using iMovie.

The screen on my ipod nano 2nd generation turns black. It still plays music. I've tried resetting the ipod to clear the black screen and the screen goes back to it's normal state but after a few minutes the screen goes black again.

The screen on my ipod nano, 2nd generation, turns black. It stills plays music. I've tried resetting the ipod to clear the black and the screen goes back to it's original state. But after a few minutes the screen turns black again, while the music is still playing. What can I do about this?

That's just the iPod's backlight timer going off, signaling the iPod's backlight to turn off to conserve battery power.
