    The standard weather app on my iphone 6 has stopped working.  It shows just my wallpaper grayed out when I try to access.  The app can be restarted or deleted and reloaded?  If so, how?

    No, the soft part of the operating system, so it would mean reload the iOS together. Have you tried a forced reboot yet?

    Close all open applications by double-clicking the home button, and then drag to the top of the application window until it disappears from the screen.

    Reset your device: press and hold the home button and the sleep/wake button until the screen goes black, and you see the Apple, then let go. (No data loss)

  • Qosmio G30-153 stops and restarts when you try to run programs and games

    I bought inscribed in the computer of 22 days ago. After 4 days of work without problem the laptop started to plant a blue screen, mainly with the "MEMORY_MANAGEMENT" error

    Very often when you try to play a 3D game or using any program (internet browser, file manager or almost). As the Blue error screen is essential to the system, the computer restarts by itself, but even more often an (specific to the program or to a standard error window

    Windows "(nous sommes désolés, mais le programme doit mettre fin à cause de l'erreur...-une erreur principalement dans certains fichiers.dll dans le répertoire Windows) appears disabled to continue the work on the program until you restart manually."

    I restored the system once already - it did not help, I also downloaded the latest drivers, including upgrading the Bios.

    What can be wrong, I have no idea. Help, please...

    Hello

    Can you please tell us what games you have preinstalled and programs? Description of your problem is quite general and it is not possible to have any concrete indication that may be the problem. For some time, I have G30 and operating system runs very stable with standard applications such as Microsoft Office, Skype, Icq, MSN messenger and IE7 with LAN and WLAN connection.

    Up to now, I really didn't notice any problem. Because of this, I really want to know what programs you're using.

    Method 2: You may need to check the settings of the BIOS (Basic Input\Output System). Check if the hard drive is detected. If this is not the case, check the physical connections. Refer to the manual to check the same.

    Warning of the BIOS:

    BIOS change / semiconductor (CMOS) to complementary metal oxide settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the configuration of the BIOS/CMOS settings can be solved. Changes to settings are at your own risk.

  • Vista restarts when you try to configure the updates (stage 3 of 3 0% complete)

    Hi all

    Some time ago I got a video card fails on me during an upgrade. Of course, I had to stop him to bring it to the store for repair. Given that the video card has been fixed I can't restart the machine at all.

    I tried to start in safe mode, but unfortunately it did not work. I can not connect because she also tries to apply the update on hold in this mode. From last known good startup didn't work either.

    I also tried to recover from original DVD, but it did not help. Auto repair has failed, and it did not find my disk-based restore points when I tried to recover from a restore point (and I know that I have several of them already...).

    I don't want to lose the data on this machine (and yes I learned the hard way to do backups and I bought an external hard drive for this purpose), so from scratch is not really an option for me.

    Help, please!

    D.
