IMac screen turns white, then won't restart

24" iMac running 10.6.8
Just installed MacKeeper software and did a "Fast Cleanup". It says my system is running "excellent". Then, one day later, I am on the internet and the screen goes white. Pulled the plug as that was the only way I could get it to shut down, restarted, screen is now 50% white (frosted) but I can see the type. As I am talking to MacKeeper on the phone, it goes completely white again. Third time try to restart and button won't even turn it on. Fourth time restart (as above) and have the 50% white screen again. Long enough this time to figure out my Apple ID and password and type in this question.
Do you think this is software related (MacKeeper)? Or is this my first Mac to ever have a real problem.

Didn't get a response here, so I read some other similar posts. I've tried everything: rebooting to safe mode, uninstalling MacKeeper, and running disk utility (which said it could find no problems).
Any other suggestions out there folks?

IPhone keeps returning to DFU Mode, Screen turns white then yellow when restoring

I recently got a iPhone 3GS, I didnt jailbreak or anything. I was planning to restore and update to 6.1.3. After the restore it went directly to DFU Mode and wont exit. When I restored again, the screen turned white, when the itunes said preparing to restore, the screen turned yellow and restore proccess wont continue. PLEASE HELP!!!!!!!

I have the same problem. An iPhone 4S, 6 months old, stuck in DFU mode, black screen and iTunes can't restore (error 1600). Tried reloading iTunes, tried 3 different computers (Win 7, Vista, OSX) all report the same problem.
This phone has never been jailbroken (don't need that in Oz because my carrier doesn't lock their phones). It still had the original iOS that it came with from Apple.
Like migsiliciousI read lots of post about using jailbreak software to kick the phone out of restore mode without installing a custom OS, but I'm not going to try that as the phone is still under warranty. If there is no simple solution to the 1600 error, then I'm going to have to travel 40km to the nearest Apple Store and see what they can do.

My iPod screen turned white and won't respond to anything I do.?

I set it on the couch and picked it up and the screen turned white. I tried to reset it (holding the home and on/off button for 15 seconds) and that did nothing. So then I charged it for an hour and reset it again and that did nothing. What do I do? By the way I have the 4th Generation 32GB iPod Touch. I don't know my IOS though, I know I updated it a couple months ago to and IOS 6 it had other numbers too but I forgot.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

I have a 32in 1080p Sony Bravia. and a early 2009 iMac 20in. i bought a mini Dvi to HDMI adaptor. And i have the HDMI cable. but every time i connect my iMac with my Tv my iMac screen turns blue then back to the desktop.

i also click on detect displays and nothing happens.

You have the display set in Extended Desktop mode. In System Preferences>Display there should be an Arrangement tab when you have the TV hooked up to the MacBook and both screens working. Do you see two monitors side by side? One of them will have a Menu Bar at the top. Just click on the Menu Bar and drag it to the second monitor. That will make the second monitor your main screen. When you disconnect from the TV your Menu Bar will automatically change back to the MacBook.

My phone screen turned white and won't stop playing pandora. it wont minimize or turn off

Let the battery fullu drain. After charging for at least an hour try a reset and restore.

Hi, I accidentally spilled water on my Mac Air on the very right side of the keyboard. After a few minutes, the screen turned white and a gray folder with a question mark came up and kept flashing. THEN IT DIED HELP.

After the screen turned white and the folder popped up, it just kept flashing. After a few minutes the screen just turned white completely and I could hear the noise of the drive. It just sat there still with the noise for a good few hours until the battery died and then my mac just shut down completely. I tried to see if the computer could charge, and it does charge. I just can not turn the computer on no matter what. It is dead. It might be the logic board or the drive...I'm hoping it won't cost me a new computer because I just got this 5 months ago....

Do not attempt to charge as that will only make the damage worse. You need to take the MacBook Air to an Apple store genius bar and have the technicians check and see what repair work is necessary. It only takes a very small amount of liquid to cause short circuits and damage.

If this does not resolve the problem you have a hardware problem.

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?

IMac (3.4gHz Intel Core i7) shuts down when sleeps, then won't restart

Just bought a brand new 27" iMac (3.4gHz Intel Core i7) which shuts down when sleeps, then won't restart (ie completely dead).
In order to restart, I have to unplug the power cord from the computer, hold power key down for 10secs, replug in and it then starts up. I returned to the store and they spent a couple days letting it go to sleep etc and overnight and for them it was fine. Woke up no problems. They returned it to me yesterday.
So I set it all up again, left it overnight and this morning it was dead again. So now it leaves me to wonder if it's something I have plugged into it.
I have a new Seagate 3TB external hard drive hooked up using USB3.0. This is plugged directly into the back of the computer.
I also have a powered USB hub plugged into the computer which has regular USB stuff such as printer, graphics tablet and another external hard drive (this one is older LaCie 500gb, and have put it into a new USB 3.0 case as well for the arrival of the new iMac (this had an old firewire hard drive case). However this hard drive is switched off at the case and is not being used.
I believe it could possibly be the Seagate 3TB disk causing this problem, but it works fine during the day while I am using the computer, it's just when I either leave it at lunch time to go to a meeting or walk etc or overnight that I come back and it has shut down....leaving me to believe that it's due to the computer going to sleep.
Has anyone else had a similar problem with a Seagate drive? Today I'm conducting an experiment and heading off for lunch with both hard drives unhooked. If I come back and the computer wakes up from a click of the mouse or keyboard as it should, I will plug in one hard drive at a time and re-test. I will leave the Seagate for last, as I don't think it is the old LaCie disk (which is off).
For reference sake, I also have a NAS running off my network through Airport Extreme etc and have my old iMac hooked up to the network too, but don't believe this is the problem.
Initially I did put in some after market RAM (another 8GB) and though that might be the problem, but I removed and it still reacted the same way (plus store I bought it from again booted up fine and woke up fine at their shop after I had taken RAM out too).
Will keep this post updated with my next test (letting computer sleep without either hard drive in), but keen to hear if anyone has had any similar experiences with Seagate disks/cases and the new iMacs.
Cheers,
Kristin

Hey kristinandmike,
I had a similar problem shortly after I bought my 27" iMac. Here is an excerpt from my discussion:
"As BDAqua suggested, I started the process of elimination by shutting down the externals and just leaving up one of the USB drives and using the computer until time to shut it off. After eliminating 2 of the 3 drives I figured it had to be the last one. That drive is a Seagate GoFlex Desk version that allows different bases with differing connectivity. I had previously used FW800 to connect but had switched to USB3 on the new computer. I went ahead and got a Thunderbolt to FW adaptor cable and switched this drive back to Firewire rather than USB3. So far so good."
For some reason the Seagate I was using didn't agree with the USB3 on the Mac.

My ipod screen went white, then turned blank and will not respond to the buttons i touch. it is also able to open up now somehow, so i can see the inside

Let the battery fully drain. After charging for at least an hour try:
iOS: Not responding or does not turn on
If not successful time for an appointment at the Genius Bar of an Apple store.

When I select view Apple ID the screen turns white

I'm trying to change my credit card info in my phone so I go to iTunes and app settings and then select Apple ID and view Apple ID then the screen turns white and it stays like that. How can I fix this?

Hey there Vicky,
It sounds like your account info screen is not loading correctly on your iPhone 5s when you try to edit your billing. I would start by signing out of the iTunes & App Stores in your settings first. Then quit all the running apps on the device with this:
iOS: Force an app to close
http://support.apple.com/kb/ht5137
Double-click the Home button.
Swipe left or right until you have located the app you wish to close.
Swipe the app up to close it.
When you have done that and restart the phone, sign back into your account and test the issue again:
iOS: Turning off and on (restarting) and resetting
http://support.apple.com/kb/ht1430
Thank you for using Apple Support Communities.
Take care,
Sterling
