Random crash : the screen gets frozen. ANy help ?
Hello,
I am getting bored with regular crashes. Symptoms : this usually happens while I drag the mouse, click somewhere (it happens in various apps), then suddenly the clock stops. Nothing is possible then, just hard reboot.
It also happens that the screen gets totally white, or with some thin horizontal stripes.
I tried to fix the disk permission, they are OK, but still, the crashes happens pretty often.
I was used to that with a PC, not with a Mac...
Anyone can help telling what to do and how to identify the problem ?
Thanks

Imac 8,1 here as well. Your issue was identical to mine. Out of Applecare so I opened it up, for the third time, got the screen out so I could access the NVidia 8800 MXM card. I took the heat sync off of the GPU and CPU. Cleaned the GPU and removed all flammable items from it. (I think it was just a foam pad, it's been awhile) I covered the little silver capacitor with alimunim foil to help protect it from heat and them I baked it chipside up in my oven for 12 minutes at 400F. I repasted the GPU and CPU with Shin Etsu X23 Aluminum Oxide compound. Reassembled completely and walla, no more white screens or lines or black screens.
My crashing would occur always at 140F or higher. Use a iStat to track that temp to see if yours follows the same pattern. Overall, I saved over $1000 in repairs by just researching and fixing this myself. NVidia used a high lead solder hwich is brittle and cracks when it heats and cools rapidly. The Shin Etsu keeps my GPU 10F cooler at idle and I haven't had an issue in about 4 months so far. I leave it on all the time too.
If you attempt this, make sure to research it. There are good videos online on how to do this. The Apple store will indicate you need special tools and a dust free room. You will need a Suction Cup, T8 & T6 Torx driver, probably an air can. I used my bethroom misted with fan sucking air up to keep dust down.
Good luck.

I Downloaded a update on my iphone 5 and now the screen is frozen any suggestions on how to fix
Good Afternoon rossiebud,
If your iPhone is not responding after your update, try the steps in the article below. If restarting or resetting your iPhone doesn't get you back on track, then you can reinstall the iOS by selecting Update while in recovery mode.
If your iPhone, iPad, or iPod touch doesn't respond or doesn't turn on - Apple Support

Hope that helps ...

I plugged my ipod into my computer, and it didn't come up on itunes. So I unplugged it, and when I did, the screen froze on my ipod. The backlight has been on the whole time. It is in hold, but the lock is not showing up on the screen. On the battery, it shows the lightning bolt, but my ipod is not plugged into anything. The buttons are all frozen, I really need help! Please answer.

MY iPod broke help
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 another cable
- 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 suspect whatever caused the broken screen progressed.

I went into a web page I must have left My Ipad in the web sight when I went to use it again the screen seems frozen. Anything I do I can't get a response. Please help
Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons.

Just turned on my MBP 2007 and the screen gets stuck on the light blue before the normal log in page comes. Any Clues?
Worked fine last night. It's running Snow Leopard.Does your iMac fail to boot every time or only some of the time? Here are some things to try:
- Boot into "safe mode", which will run the equivalent of Disk Utility's "repair disk" operation.
- Boot from the system install disc that came with that Mac with the "D" key held down to run the diagnostics. Run them several times to see if any hardware problems are reported.
- If you can't identify the problem or fix it any other way, download and install the OS X 10.6.7 "combo" updater.
- If that still doesn't help, try reinstalling OS X 10.6 over the top of what's on the disk. -

i recently upgraded my 4s to a 5s. the verizon store took my old phone for a trade in. i cannot get any of my pictures to download from icloud. my photo stream folder only has a small percentage of the photos in it. any help would be greatly appreciated.
That's possible if he didn't connect to a WiFi hotspot after taking them. I don't think the "Personal" Photo Stream uploads over Cellular, unless they changed it since the last time I used it.
If that's the case, then the photos likely didn't upload to Photo Stream and are stuck on the phone.
And you're not going to be able to get them back, either. -
have an ipod and then got the wife an iphone4. all passwords are screwed up. she can not access playstore cuz she doesn't have password. i can not get find any help on how to get or update a password for the ipod. and then get her a separate password for her iphone. we need to save her photos, music, etc to ? icloud and the phone stuff to verizon cloud? so when she gets her new Iphone6 she can have all her "stuff" back on the new phone. hope this makes sense. please offer suggestions here or at [email protected] thanks for your help!
Oh no! I'm sorry to see there's a lot of confusion here and data shared, x-rayDon. We can definitely work to fix. This happens when two devices share the same Apple ID, so she will need to reset hers. She can do so by assessing this link Apple - My Apple ID. You will need to decide who will keep the account if want separate Apple IDs since purchases cannot be shared unless you do Family Sharing.

I have iphone 5 and when I take picture and then later send it via text message to another person with iphone 5 the photo they get is always cropped on the right side. Any help?
Make sure the contact has a 10-digit number, not just the 7-digit number.
If that isn't it, does the problem only happen with iMessages, SMS or MMS messages?
Try tapping Settings > Messages, then turn SMS and MMS off. Test, then repeat again only leaving SMS or MMS on.
