• iPad Air keeps crashing and restarting

  Why my iPad Air keep crashing and restarting in Safari? I also think other applications. iOS 9.3.2 must be the culprit because it never happened so often. Any solution?

  Go to settings - Safari - clear the history and data from the Web site.

  If that doesn't work, reset your device. This will not erase your data stored on the phone.

  • Press and hold the sleep/wake button
  • Press and hold the Home button
  • Press and hold both buttons until the display turns off and on again with the Apple logo on the subject.

  Alternatively, you can go to settings - general - reset - Reset all settings

  If that doesn't work, restore your device to factory settings. Please note that this will delete the data on your device.

  Take a look this Apple Support article: use iTunes to restore the iPhone, iPad or iPod to factory settings - Apple Support.

• Satellite A500 - crashes and restarts when I play games

  Help, please

  For these last months, I had a problem with my laptop crashing and restarting in 10-20 minutes from a game.

  Please help, give me ideas or tell me how to find out what the problem is, I have read a few other discussions to talk about questions of heat but no real answer on how to solve the problem.

  Help, please
  Thank you
  D

  Hi Dale.Johnston,

  Overheating would be a typical pattern of this behavior. I mean, that's if the laptop has a higher internal temperature and it will immediately fit to protect the equipment. Then it the normal behavior of s from overheating.

  Overheating may have different reasons. In most cases it's dust that blocks the fan. This would mean that you have to clean the cooling system of your laptop using the jet of compressed air to blow the dust from the cooling fans.

  Generally, it should help. If this isn't the case, I would check the display driver. What display driver and operating system you are using?
  If you install the display driver Toshiba not they can also cause overheating if it recommendable s using Toshiba pretested drivers only. ;)

• My computer crashes and restarts with windows xp but it does not occur with any other OS

  When I use windows XP, 2000, ME, 98 in my computer (Dell latitude D600) it crashes and restarts all of a sudden. But when I installed winodws vista, 7 or ubuntu it will never happen. I thought that the problem could be drivers, so I ran my computer only with windows XP, without installing any driver, but it happens again. I already send my computer to dell and they changed everything in the computer, but I still get the error. What can I do to identify and solve the problem?

• Guard Windows Explorer to crash and restart on Windows 7

  I use a Dell Vostro V13 laptop. Last night suddenly kept windows Explorer crashing and restarting over and over to the point where I can't do anything. I tried the system restore, but the problem is still there. I can't do anything except the exit ramp of the computer with Ctrl + alt + delete.

  I am only able to send this message in SafeMode where the problem occurs.

  To solve most computer problems, it allows to watch the evidence available in the system information file and Event Viewer logs. An experienced eye can choose needles in a haystack and see more clearly the precise nature of the problem or problems.

  Please provide a copy of your system information file. Type the system information in the search box above the Start button and press the ENTER key (alternative is select Start, all programs, accessories, System Tools, system information). Select file, Export and give the file a name noting where it is located. Not to place the cursor in the body of the report before exporting the file. The system creates a new information file system each time system information is available. You must allow a minute or two before the file is completely filled before exporting a copy.

• MacBook crashes just after an hour

  Towards the end of July 2016 my MacBook (13-inch, aluminum, Late 2008) with OS X El Capitan 10.11.5 version (15F34) and 256 GB Solid State SATA drive began to break each time exactly one hour after, he turned. First, I assumed it was due to bad battery because I have not changed it since I bought the computer. I bought a new battery, but it did not help. I ran using disc using disk utility, and it found no errors. The accident starts with the freezing system and round Rainbow rotation pivoting for several seconds. Then, the system and application partially crash or in most cases, the system locks and the screen goes black. After I restart the computer, the system runs again normally within 60 minutes exactly, and then it crashes again. I found the article with the similar problem where the software Cocktail caused this problem, but I don't remember to set everything up. Help, please!

• iMac crashing and restarting on its own

  Hi all

  My iMac has been crashing lately and restart on its own. After trying to solve what was going on, I noticed that, just before these accidents occur, the following 2 warnings repeatedly appear on the Console:

  kernel [0]: could not open the file 2

  kernel [0]: vm_swap_create_file @ 1554 dry failure

  During the inspection, I realized that the var, there is no /vm folder and, therefore, no swap file, that made me suspect that the problem is related to virtual memory.

  I tried to launch an intensive application of memory while monitoring the use of memory through Activity Monitor and, of course, when all memory is used, the system crashes. Used swap shows 0 bytes at all times. In comparison, my MacBook Air has always a certain amount of used Swap data, even if some memory is used.

  I tried to verify if the virtual memory was somehow disabled, by using 'sudo launchctl load-w /System/Library/LaunchDaemons/com.apple.dynamic_pager.plist' but it seems that the service is already loaded.

  I'm at a loss and need help. Someone at - it clues about what is happening?

  You can have the logic board replaced, but that will be your responsibility. You can download this provisional application:

  This will allow you to disengage the discreet GPU and use only it integrated. This will stop the panic kernel, but at the expense of the graphics performance.

• iMac 2015 randomly crashes and restarts

  I have a 2015 27 "iMac 4 GHz with 32GB of RAM from OWC and necessary devices connected via USB and Thunderbolt running El Capitan (updated) and are experiencing random crashes every day.

  Most of the time I'm just browsing through Safari. All of a sudden, the machine crashes, including the mouse pointer and after about 10 seconds the machine will restart and everything is back to normal, as if you start the machine manually. So, no messages saying: it was an unexpected stop, no accident recover/journalist, nothing.

  Checking the logs is without kernel panics. The only thing I can find in the system.log is a recurring cause:-128

  Encounter the same problem or does anyone know what this error code is talking about?

  (Devices: Sonnett Express SE II with Blackmagic Decklink and ATTO HBA H680, mini monitor that connects to a tape drive HP Ultrium 3000 SAS, a TVS - 871T, a Wacom Intuos 5 QNAP NAS and some card readers.)

• MacBook Pro keeps restarting after iPhone updated 9.3.5

  Given that I didn't have at least a 50% load, I connected my iPhone 6 s to my MacBook Pro (10.11.6) updated the phone to v. 9.3.5. The phone updated fine, but now my Mac keeps on rebooting over and over again. The display shows the Apple logo and progress bar, but there are thin horizontal red lines across the entire screen. When the progress bar is full, the gray screen runs for about 10 seconds and then restarts, and it does the same thing again. I have absolutely no idea what to do. Can anyone help?

  Hello robbob116,

  Thank you for using communities of Apple Support.

  If I understand your message that after upgrading your iPhone 6s to iOS 9.3.5 via iTunes on your MacBook Pro, your MacBook Pro now repeatedly restarts. I know how it is important for your MacBook Pro start correctly for you. The first step I would recommend would be to start up your Mac in Mode without failure. The following article explains the use of Safe Mode and the steps that you will need:

  Try safe mode if your Mac does not end commissioning
