  Have you checked to see if the computer is overheating all in game.  Games is intense and can cause a heat.  This can certainly cause the computer to reboot unexpectedly.  There are many FREE programs that you can use to check the time.

  Thanks for the tip I will load CPUZ and check the temperature which would be the specs of temp on this one

• BlackBerry 8350i smartphones turns off By itself and back!

  OK, I have an 8350i by Nextel. A couple of weeks my BB itself off and turned and then turn the. I don't think much of it until he started to happen very frequently. When I say often, I hear every 10 minutes. Pretty frustrating for a phone that I use for work. I took it to a local service, but they didn't know what was going on so they simply slipped the software and reloaded it. This solves the problem for about 24 hours, and then she went back. There has been sporadic with about one day between each of them, but it has since become a very common question again. It happens about 5 times a day I know. It's embarrassing and I hope someone can help. Thank you in advance!

• WiFi falls frequently, must turn off wifi to the computer, then turn on

  Greetings,

  I have four Macs, all the different models and with different OS, with El Capitan and this happens on all. I have an Airport Extreme router, aged about 1 1/2 years. Throughout the day, wifi doesn't work. To get to resume, I have to go into menu wifi on the computer, turn off wifi, then turn it back on. This example gets going again.

  I tried using automatic channels as well as various specific channels on our Airport Extreme. I also have 5 GHz and 2.4 normally. I, of course, restarted a gazillion times (this has happened for about a year). I still have to find a solution.

  Suggestions?

  Thank you!

  Amy

  It is possible that you have a faulty AirPort base station, the other thing to ask is: do you live in a place with a lot of other Wi-Fis operating? As an apartment or condo complex... or a dorm student perhaps? Connectivity spotty Wi - Fi is usually associated with some sort of interference of a Wi-Fi connection. Other Wi-Fis in the close vicinity would be a major culprit.

• Why my internet accounts automatically get disconnected after that my computer turns off by itself?

  I have a Compaq PC with processor Dual-Core AMD Athlon X 2 5000, and it runs Windows Vista Edition Home Premium... In my view, that is running Service Pack 2. I use the computer to check my e-mail, my YouTube and Facebook accounts (and possibly other accounts spread I connect to).

  I usually use Internet Explore to browse the web. Sometimes my computer turns off by itself due to overheating. But whenever when this happens, when I turn my computer back on and return to the use of the Internet, I've totally frustrated to find that all my accounts were automatically disconnected!

  Even when I check these boxes to keep me connected to these accounts when I turn on the computer again after a successful stop, my accounts still get disconnected!

  It only seems to happen when my computer turns off by itself without stopping... mainly due to overheating. When I turn on the computer again after a successful regular stop, my accounts are automatically saved on once again, due to activate me "Keep me connected" by checking these little boxes. But after a situation when the computer is off all the time (either by himself for a reason, either by me with strength to turn it off when my computer crashes), my accounts do not remain.

  How can I prevent my accounts automatically be disconnected so that whenever I start the computer, after it turns off by itself, my internet accounts turned on? There must be a patch for this embarrassing situation here on the internet.

  Perhaps because an improper shutdown / forced can inpact on different parameters.

  Hello

  Could be heat related - try using a small fan to blow into the air intakes to see if that helps.
  It is just like it loses power or stop it in the normal way?

  Remove ALL power and reinstall all the memory cards and cables (both ends where possible).
  in fact, remove and replace - don't do not just tight. Remove the dust bunnies and clean the
  air vents. Check that fans are working (before and after opening the case). When your laptop on all the
  You can do is to reinstall the memory and clean the vents (still may try to add a small fan as a
  test).

  This sounds like material so if the above does not help you then probably need help

  Vista and Windows 7 updated drivers love then here's how update the most important.

  This is my generic how updates of appropriate driver:

  This utility, it is easy see which versions are loaded:

  -Free - DriverView utility displays the list of all device drivers currently loaded on your system.
  For each driver in the list, additional useful information is displayed: load address of the driver,
  Description, version, product name, company that created the driver and more.
  http://www.NirSoft.NET/utils/DriverView.html

  For drivers, visit manufacturer of emergency system and of the manufacturer of the device that are the most common.
  Control Panel - device - Graphics Manager - note the brand and complete model
  your video card - double - tab of the driver - write version information. Now, click on update
  Driver (this can do nothing as MS is far behind the certification of drivers) - then right-click.
  Uninstall - REBOOT it will refresh the driver stack.

  Repeat this for network - card (NIC), Wifi network, sound, mouse, and keyboard if 3rd party
  with their own software and drivers and all other main drivers that you have.

  Now in the system manufacturer (Dell, HP, Toshiba as examples) site (in a restaurant), peripheral
  Site of the manufacturer (Realtek, Intel, Nvidia, ATI, for example) and get their latest versions. (Look for
  BIOS, Chipset and software updates on the site of the manufacturer of the system here.)

  Download - SAVE - go to where you put them - right click - RUN AD ADMIN - REBOOT after
  each installation.

  Always check in the Device Manager - drivers tab to be sure the version you actually install
  presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
  in particular that) so to install a driver - reboot - check that it is installed and repeat as
  necessary.

  Repeat to the manufacturers - BTW in the DO NOT RUN THEIR SCANNER device - check
  manually by model.

  Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

  If you update the drivers manually, then it's a good idea to disable the facilities of driver under Windows
  Updates, that leaves about Windows updates but it will not install the drivers that will be generally
  older and cause problems. If updates offers a new driver and then HIDE it (right click on it), then
  get new manually if you wish.

• How and when the computer turns off automatically?

  Listen to internet radio, Sys Pref > saving energy on the default setting, wake up and radio program cut.

  This is great... .buth how and when the computer turns off?  When I reopen it wifi comes back, I'm correct when she stops she also turns off wifi?

  Hello allan299,

  Thank you for using communities of Apple Support.

  According to your post, I see that you have any questions on how and when your computer shuts down, and how the WiFi on your Mac is affected. I know it's nice to be able to properly manage what happens when your computer stops and starts in mode 'sleep'. I'm happy to help you find the best resolution.

  You're right, when your computer stops completely it will turn the Wi - Fi. If you enable the wake for network access, Wi - Fi remains lit, and you can access shared resources on your computer, such as printers or iTunes shared playlists even when your computer is in "sleep". Definition of a calendar closing and start on your Mac can also be useful.

  Check out the following resources that will help the set options that control the energy use of your computer, sleep, and wake-up times for your Mac and the calendar from your Mac to turn on or turn off or go to sleep:

  OS X Yosemite: energy saver Preferences

  OS X Yosemite: set sleep and wake up on time for your Mac

  OS X Yosemite: A schedule for your Mac to turn on or turn off or go to sleep

  Best regards.

  Did you do the changes on the computer outside of download sound card drivers?

  Step 1: Roll back the driver of sound card and see if that solves the problem of the sound card.

• 2-3 days after the expiry of my warranty of one year, my computer turns off suddenly during use. I rebooted, but it stopped again.

  2-3 days after the expiry of my warranty of one year, my computer turns off suddenly during use.  I rebooted, but it stopped again.

  The model is that the computer runs for 15-30 minutes, then suddenly stops, the system reboots, runs for 2-3 minutes, stops, restarts, spans less than a minute, stops, restarts, stop after a few seconds, etc., and at that time there I give until the next day when I repeat the same cycle all over.    I have Windows Vista Home Premium 32 bit and it is a model of Dell Inspiron 518.  There is no error message but a beep at startup upward.  I ran Windows repair program 'Start' who did a restore without success.  The problem occurs even in Safe Mode.

  Does anyone have a guess as to what is the diagnosis?  Thank you.

• On the start with progress bar page, after that it becomes a little more than half, the computer turns off.

  MY MacBook Pro is frozen and I had to turn off get out of the frozen page and when I pressed the button to turn it on it makes the departure noise and then the progress bar lights. When it becomes a little to Midway, the screen goes black and the computer turns off.

  The progress bar that starts from the left end appears when your startup disk is too damaged to mount. The illustrious progress is the functioning of the equivalent of disk utility (ERD). He is never more than half before taking a decision.

  If your drive CAN be mounted, start-up continues normally.

  If your drive cannot be mounted, your Mac stops, because there is nothing productive that it can do.

  If your Mac is trying to start and crashes, which can produce always different results, but that doesn't seem to be the case here.

  I recommend that you start in recovery and run utility disk (ERD) until it comes clean or is hopelessly.
