    Hi DreamMeng,

    You can try to use third party software to back up data and check.

    You can use your favorite search engine to navigate on the third-party data backup software and that the software allows to save data.

    Note: The use of third-party software, including hardware drivers can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the use of third-party software can be solved. Software using third party is at your own risk.

  • The Explorer does not start, the Task Manager does not start, safe mode does not start. Wat to do?

    I have recently been diagnosed with some sort of spyware / trojan in Avira and, apparently, he had removed. Apparently NOT.

    Yesterday my laptop crashed and explorer.exe would not load at startup. The screen is all black with just the cursor. Windows Key + R is not raise Run and Alt + Ctrl + Del to appear the option lock and stop... but no task manager.

    Safe mode has the same problem. I tried the option restore also, but all the restore points has mysteriously disappeared.

    I wonder if there is no solution without a ridiculous amount of data backup and restoration of the entire system. Thanks in advance

    Hello

    You can access Mode safe? Repeatedly press F8 as you start? If yes you can try Control Panel - device
    Manager - graphics card - Double click on - driver tab - click on UPDATE driver - then right click
    on devices and UNINSTALL - REBOOT.

    Another method to try to get to the desktop (try in normal Windows Mode without failure)
    CTRL + ALT + DELETE and on the tab process EXPLORER.exe and COMPLETE the PROCESS on this subject - then
    on the Applications tab - lower right - new task - type in EXPLORER.exe. Safe mode is reached
    by tapping F8 as you start several times.

    First check this thread in case it is simple and if not to come back to this thread.

    Black screen problems are extremely difficult to repair and all patch is usually on a base hit or miss.
    That there is no information on a black screen as it is on a blue screen just adds to the
    Difficulty. Often using a restore point or Startup Repair will have no effect. You can try a

  • Able to boot normally to Windows 7 but can not start safe mode

    Hi, I have a laptop of Lenovo who has Windows 7 Home Premium installed on it.

    I had a few problems with not being able to see all the videos on CNN or the Weather Channel site, is not showing me any local report.  So I thought that I would try to start safe mode to make certain shortcomings.  (I can see videos very well elsewhere).  This happens on all 3 browsers I have (11 IE, Firefox and Chrome.

    However, after pressing F8 and get the option screen, once I chose the Mode safe mode (with or without network) it works the list of drivers and then darkens with only the arrow on the pointer in the center of the screen and stays like that for a long time without anything happening.

    I already ran all antivirus programs and spyware that I have, but nothing changes.  Any help would be appreciated.

    Thank you.

  • My computer has a virus, can I start safe mode and download the scanner software?

    My daughter has a virus on his computer and he was arrested for perhaps a year. Can I try and see if it will boot in safe mode and down load a service of scaning as Mirco soft essentials for a scanner or Malware Anti-malware bytes. I guess my question main you can down load a program in safe mode.

    Hello

    Of course you can. Use safe mode with networking to download directly on his computer--several times

    resident who can cause as many questions as the malware and may be harder to detect as
    the cause.

    No one program cannot be used to detect and remove any malware. Added that often easy
    to detect malicious software often comes with a much harder to detect and remove the payload. Then
    its best to be thorough than paying the high price later now too. Check with them to one
    extreme overkill point and then run the cleaning only when you are sure that the system is clean.

    It can be made repeatedly in Mode safe - F8 tap that you start, however, you must also run
    the regular windows when you can.

    Hello

    I have a VBScript script that I created to add a little extra security to my machines and I running normal start very well. What I want to do is to prevent users not allowed to Dodge it and boot into safe mode to access my machine.
    Y at - it a registry key that I can modify my script even in my machine to start in safe mode?

    The answer should be "No, it isn't" like Safe Mode is designed to use only the components of the system designed by Windows.

    You might consider disabling the F8 key to prevent the safe boot mode.  Here are some links that deal with the ways to do this: -.

  • Can not start safe mode

    I know how to do this. Whenever I try, I go about this Mac, and then the reporting system and double click on the software.

    Then he said: I'm in normal mode. I tried with two keyboards, to check if the shift key works.

    Restart the computer. At the chime, press on and hold down the SHIFT key until the Apple logo appears, and you see the progress indicator. If you are in Safe Mode , then you will get a login screen that says Safe Mode. Make sure that you are using an Apple keyboard and mouse. Disconnect all other devices, as appropriate.
