operationBindinding is null - this result is also null
result = operationBinding.execute ();

my computer crashes, I press ctrl alt delete and it thaws
original title: don't know what's wrong
my computer crashes, I press ctrl alt delete and it thaws, this happens very often, he does not have it for weeks at a time and then it again. I'm a paint shop pro user, I uninstalled and reinstalled psp more 2 browsers, firefox and chrome. My main browser is lunascape which he doesn't seem to be a problem. On chrome when I click on a tab, it closes. I can't copy on firefox. It did not help. Also, when this problem is occurring, I can't drag and drop only cut and paste. This has happened for several months. Someone told me I have a memory leak, but do not know that for you, I was getting ready to reformat with a full system restore and that said person who would not help, but again, I am not sure it is. I ran the antivirus scans, nothing I don't know what to do. I use a dell inspiron 531.

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.

Click right does not work. Profile already deleted and started in safe mode
I googled and used solutions of mozilla for safe mode, delete and create a new profile (deleted all files) disabled all the plugins. I discovered a problem where clicking on ask to activate does not drop down to select another option. I tried the plugins folder thought I could delete all the plugins and start again. Nothing I've tried has worked at all. I also uninstalled and reinstalled the latest version. I noticed that the version installed is under program (x 86), which is where I thought that 32-bit applications are implemented? Anyway, even by selecting text on a page and right click does not work
You have a problem of mouse anywhere else?
The software on your system is up to date?
Start your computer in safe mode with network. Then launch Firefox.

I just bought the latest iPad and now I have restored from a backup, it has been deleted and the songs at random out of my playlists for example a playlist, used to have 534 songs (I know because they are always on my ipod) and now he has 137. Why he did I have no idea. The songs are on my Itunes yet, but not playlists which is why I think it must be some sort of bug. Help, please.
p.s. Ideally I'd like just use my ipod as a backup (can I do that?) but I can't connect to the risk to delete playlists.

I don't know exactly what you're asking here. It seems to me that you deleted a few MMS, and you try to get back them. Is this correct? If so, then if you have a backup of the device that was made so that the MMS were still on the phone, then Yes, you could restore this backup unit to retrieve the MMS. However, understand that everything you've done since the backup was made will be removed.

I even deleted and reloaded firefox, Thunderbird , but it continues to try to recover a deleted account emails. Where it becomes the info to try to access the account? Tools/choice of account does not contain the account more.
The title of the question and first sentence edited by moderator. This question is about Thunderbird, not Firefox. AW
Something was quite wrong. Settings that use Thunderbird cannot come from his profile, but if the account has been for settings and yet the account is always logged, then the settings page has become out of step with the real state of the profile. Note that uninstalling and then reinstalling the program Thunderbird are usually ineffective because the settings are kept separately in the profile folder.
I would go to tools | Options | Advanced > Configuration Editor and search for it references to the unwanted account and see if they can be removed by here. If this fails, I close Thunderbird and browse the js files in a text editor. If you do this, be sure to make backups, because if the files are preferably incorrectly formatted, Thunderbird will not start.

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)

Apple ID hacked, iPhone deleted and locked
Hello
Apple ID my brother hacked, iPhone has deleted and locked. When you set up the phone he asked once again for the Apple ID and password which is then said to be incorrect. When he tries to change his password on https://appleid.apple.com/ it says that the password is incorrect and more - there is no such an Apple ID. Then of course, it has been changed as well. He also received a letter from the hacker asking little money for recovering his Apple ID. Has attempted to call Apple support - nobody takes the phone even if it is an hour of work. Is it possible to reset the iPhone to factory settings, so that he can use it? ITunes will restore aid? Also, how can we get Apple to answer calls?
Thank you
Edgar.

all my files were deleted and I don't know how to retrieve them.
Original title: maintenance cleaning disc
all my files were deleted and I don't know how to retrieve them.
Hi BarbaraJenkins,
· How do you delete files?
· Did you remove them permanently? (Shift + delete)
· What is the operating system installed on the computer?
You can check if the files are available in the Recycle Bin
Windows 7: recover files from the Recycle Bin
Windows Vista: recover files from the Recycle Bin
If there are no files in the Recycle Bin, then unfortunately, you maybe not be able to recover their return.
However, try looking for a third-party software that can help you to do. You may need to search the Internet.
