Grey screen, no matter what I do

Hello!

My iMac has been restarted itself recently; so I did a reinstall of Mac OS x. It seemed to work; and have no issues. Now, after surfing the net a bit, my computer is no further than the gray screen. I rebooted in safe mode; and it remains on the gray screen. Ditto for the recovery mode. I'be reset the PRam and fsck-fy done a number of times. Did a diagnostic check and it comes back as 'OK '.

IF I use the disk utility and the boot of 10.11.4; all my saved data types will be present? I just want to get to my computer to back up everything I have on it so I don't lose. I was a fool for not to do so.

Thank you in advance for your help!

If it displays a gray screen in recovery and in safe mode then the question is probably associated hardware.  I'd service.  Use https://locate.apple.com/country to find a service provider or store near you.

If you want to recover data from hard disk, you can try the disc mode target with another computer.

Share files between two computers with target - Apple Support disk mode

The built-in diagnostic test is not very complete, so it cannot report no error when there are hardware problems present.

  • My screen keeps flickering, no matter what I do. How to stop?

    The problem started when I first downloaded and started using RealPlayer, now my screen constantly flickers every 5-15 seconds no matter what program I use both. (Internet, Chrome, iTunes, etc...)

    How can I solve this problem / make him stop?
    First thing to do for a computer slow (or weird) should start to clean and see if an automatic startup program is the cause.
     
    Clean boot
    To see if other programs are causing the problem. Click on Start - Control Panel (and select Classic view in the left pane), select Administrative Tools , then System Configuration. Choose the general tab, and then click Start Diagnostics. Reset.
    Speed has been restored?
     
    The second thing is a virus check. This program is free and highly recommended.
    Use it as a scanner only.

  • Firefox refuses to save my tabs no matter what I do.

    I have the latest version of Firefox. And my computer was blue screening me recently. and yesterday, after I managed to do stop, it somehow reset my Firefox! I got most of it fixed, but it is not let me save my previous session no matter what I do. Do not ask me to restore the previous session, I tried to configure so it would restore my session every time I open Firefox and it does not work. He didn't even warn if I want to close. Seriously, I don't know what I'm doing wrong

    Make sure that you are not Firefox running in permanent private browsing mode.

    To view the history settings and cookies, choose:

    • Tools > Options > privacy, choose the setting Firefox will: use the custom settings for the story of
    • Uncheck the box: [] "always use the navigation mode private.

  • Booted XP went into the mode options regurly of open windows, or knowledge last configuration or safe mode. No matter what I choose, keeps restart and return to this page

    Original title: frozen configuration page

    My laptop running windows xp pro was fine, when I went to bed last night, but this morning I woke and went to use the lt and it started as usual but then in a mode options regurly windows open or to last working configuration, or 3 safe mode options. And no matter what I choose, it keeps restart and return to this page and has continually repeated the same steps over and over again... someone can please help me with this?

    It seems that your XP hangs for some reason any...

    Why do we know almost nothing about your system (except a laptop with XP Pro)?  I know this isn't your fault...

    Please answer these questions and to implement the following:

    Provide information on your system, the better you can:

    What is your system brand and model?

    What is your Version of XP and the Service Pack?

    Describe your current antivirus and software anti malware situation: McAfee, Symantec, Norton, Spybot, AVG, Avira!, MSE, Panda, Trend Micro, CA, Defender, ZoneAlarm, PC Tools, Comodo, etc..

    The question was preceded by a loss of power, aborted reboot or abnormal termination?  (this includes the plug pulling, buttons power, remove the battery, etc.)

    The afflicted system has a working CD/DVD (internal or external) drive?

    You have a genuine XP installation CD bootable, which is the same Service as your installed Service Pack (this is not the same as any recovery CD provided with your system)?

    If there is a problem starting, XP is configured to automatically try to start again and you can stuck in a loop not being able to go beyond the screen boot options, or none of these startup options you choose will work only.

    Sometimes, when XP has a problem starting or falls down and tries to start again, it will give you a "short" menu of boot options and none of them will appear to be good to get your system going again.  You have tried them all!

    The options are similar to the Advanced Boot Options menu XP, but the only option that you need (disable automatic error system reboot) are not offered, because XP went too far during the boot process and offers a limited number of boot options.

    If this is the case, you must call Options menu advanced boot yourself until you do not see the option:

    Disable the automatic restart in the event of system failure

    When you get the XP Advanced Options correct start menu you want to see, he has options on it like these:

    Safe mode
    Safe mode with networking
    Safe mode with command prompt

    Enable Boot logging
    Enable VGA mode
    Last good Configuration known (your most recent settings that worked)
    Directory Services Restore Mode (Windows domain controllers only)
    Debug mode
    Disable the automatic restart in the event of system failure

    Start Windows normally
    Reset
    Return to OS Choices Menu

    You need to choose in this menu is the option:

    Disable the automatic restart in the event of system failure

    Then if XP does not start normally, you will see an error screen with information and clues about the problem and then you can decide what to do next.

    If you do not see the automatic restart on system failure option turn it off, you must reset your system and start typing the key F8 on the keyboard until you see her disable automatic restart on system failure option.

    If you miss the window of opportunity F8, you must try again and start tapping the F8 key with more urgency (earlier and more frequently) until you see disable automatic restart on system failure, and then select.

    You must keep trying the F8 menu until you see disable automatic restart on system failure option, and select it.

    If your system has a Blue Screen of Death (BSOD), we need to know what the screen says:

    Here's a BSOD example showing information you provide:

    http://TechRepublic.com.com/i/tr/downloads/images/bsod_a.jpg

    Send for the nose and the Red arrows (3 to 4 lines total).

    Send all * line STOP message since there are clues in the 4 parameters.

    If it looks like there is some kind of name listed in the STOP message file, send this line also.

    Ignore the boring text unless it seems important to you.  We know what a BSOD looks like, we need to know what your BSOD looks like.

    Answering queries and results report of the disable automatic restart on system failure screen and you can decide what to do next.

  • my HP desktop computer crashes after a few minutes, no matter what I do...

  • research and new tabs take up yahoo no matter what I do in the options

    No matter what I do, the search engines in the toolbar by default return Yahoo! Remove all but Google does not help. When you restart Firefox Yahoo is the default value. Similarly, new tabs and the home page back to Yahoo after the reopening. This is a new laptop HP with Windows 10 and I just downloaded Firefox. I spent a lot of time trying to solve this problem and about to give up and to switch browsers. I bet that Chrome will allow me to use Google.

    Generally, changes in parameters are retained between reboots. If you change other preferences such as your home page, Firefox manages to retain those between reboots?

    We have an article of general support on issues that may lead to changes to get lost between sessions: How to fix preferences that will not save.

    Two other thoughts:

    (1) some software utility/security/life private changes the folder of Firefox settings between sessions. This includes Advanced SystemCare and various programs 'homepage protection' or "browsing protection" feature. If you have any software with a similar feature, disable it until everything is set as you want and stable.

    (2) you might check all the extensions that could possibly change the settings when you start Firefox. You can do this on the page modules. Either:

    • CTRL + SHIFT + a
    • "3-bar" menu button (or tools) > Add-ons

    In the left column, click Extensions. Then, take a critical look on the list on the right side. On a new installation, it is usually empty, unless Firefox has detected the extensions that already exist on your system. Something unexpected?

  • No matter what I do to get my Thunderbird as default email, GMAIL can always be default mail. What should I do now?

    I checked everything should be checked in the Thunderbird preferences, to make it the default mail provider, but no matter what I have gmail always happen to be the default email.
    TI tha.
    Thank you

    This happens when you click on a mailto link in your browser? You should maybe define TB as default, for example, for Firefox, see these instructions:

    https://support.Mozilla.org/en-us/KB/change-program-used-open-email-links

    A similar approach applies to the IE, Chrome etc.

  • No matter what I do on firefox, I get a message that the action is not reliable. How can I fix it?

    I started this morning, opens Firefox as usual. The normal task bar has been replaced by a taskbar of Bing. I couldn't get rid of him. So, I tried to reset Firefox. The taskbar of Bing was not deleted. I uninstalled firefox and downloaded the latest version and installed. I also uninstalled the taskbar of Bing as found in my list of programs. I opened Firefox and no matter what I select on the menu or on a website a message appears saying that the site is not reliable. It is as far as I can get in Firefox! The message arrives even for internal actions within Firefox. How can I fix it. It's very frustrating!

    Make a check of malware with several malware scanning of programs on the Windows computer.

    Please scan with all programs, because each program detects a different malicious program.

    All of these programs have free versions.

    Make sure that you update each program to get the latest version of their databases before scanning.

    Alternatively, you can write a check for an infection rootkit TDSSKiller.
