Black screen after the user logon in Windows 7

Hello
I use Windows 7 ultimate x 64 on my desktop. Recently, I just turned on my PC and when I tried to connect to my account after the Welcome screen, a black screen came up with the cursor and nothing else has been demonstrated. He just hung there.
There is another account in which I can start but it freezes and does not respond. I can boot into safe mode but no icons, programs do not start which is pinned to the taskbar and I must run firefox.exe via the Task Manager... System Restore does nothing. I do not have the disc to install windows 7. All other patches? Please say.

Also, the black screen goes after 40 minutes or more and I'm able to use my pc.

Help, please.
Thank you.

  • Black screen after the windows login

    Hi, I have a HP Pavilion DV7 notebook with Windows 7 Home Premium installed on it. A problem I've noticed is that, once I connect to windows during a boot, the screen is black for about 1-2 minutes. After awhile, explorer.exe would with desktop, taskbar and icons. I am concerned about this 1 to 2 minutes of black screen after the boot as it did not exist previously. I know I have options such as restoring the computer laptop back to the default state, or by using the system restore. However, I don't want to lose all my stuff, and with respect to the restoration of the system, I'm not sure when the problem happening, as it was some time ago. I have read a Microsoft article, (http://windows.microsoft.com/en-US/windows7/why-is-my-screen-black-when-i-start-windows-7) and tried all the steps with the graphics card and the regestry, but nothing seems to work.

    -Task Manager is able to open when the screen is black (shows explorer.exe running)

    -J' have the drivers on the HP support site

    -laptop is HP Pavilion DV7 3024ca

    You will need to login using the method of trial and error. Please uncheck all of the MSCONFIG Startup tab and restart the system. If the black screen issue is resolved, then check out an application every time and restart the system. This will help you to identify the program interfere.

    Hi Zach_1,

    Have you tried to launch the installation of recovery again? Maybe that something was wrong during the first installation, it might have arrived
    Then retry the recovery facility and see what happens.

    If it doesn't work you should try a normal Microsoft disk so determine if the problem is related to hardware or recovery disk.

    Hi @vikash4309 ,

    At this point I agree with the tech that look at the computer I think it's a problem with the hard drive or even the system board. They may give falsely on the test results. I would recommend that you take it back to this HP's Service Center.

    If you do not replace the hard drive recovery CDs should work as long as replace you it with another hard drive and not an SSD because they are different and the recovery CD will know how to properly partition the drive.

  • Black screen after the attempt to upgrade to windows 10

    I was trying to upgrade windows 7 on a laptop HP Windows 10. The first attempt was via the white windows logo in the taskbar. This attempt was interrupted, probably accidentally turned off the button wifi trying to move the computer. The second time I tried to use windows ten upgraded Installer. I did the usual download and installed up to 99%. He remained on the installation of 99% during the night and the next morning without change. I turned off the computer and he made a series of updates before shutting down for good. When it starts again, it has a black screen but the cursor is there and movable. I tried in safe mode for the repair and restoration of the system, but it did not work. I tried to reset the BIOS to default, but does not. I try to leave the computer turned off for an extended period of time disconnected from the internet to see if that helps. The last attempt to start, windows 7 seems to start but then ends up on the black screen and I held down the power button to stop it. I'd rather upgrade to windows 10 if possible, but if cannot then if can go back to windows 7 will be enough. It worked great on Windows 7 before trying to upgrade, so there is no problems with the computer.

  • black screen after the mode standby, windows 8

    I upgraded my laptop HP dv6 to windows 8. I get a black screen after I wake up from sleep mode. as if the monitor has no power.

    In fact, I solved the problem by upgrading my graphics card driver.

    but I was troubled because I thought that it was up-to-date.
    display the properties of the computer - device manager - adapters - NVIDIA GeForce GT 230 M
    I have a click right on NVIDIA GeForce GT 230 M, and then clicked on update driver software. He told me that the driver was updated.
    but I checked the nvidias site. There, I found a newer version.
    It was confusing. Why windows can't find this newer version?
  • Vista black screen after the loading bar

    I have the problem that I am assuming that almost all users of Windows Vista have probably experiences - the black screen with the white cursor lonely after the loading bar 'Microsoft Corporation'. Here are the steps that I tried to solve the problem, but have not yet worked:

    • With the help of "last known good configuration" brings back me to the screen and the white slider
    • Go into safe mode which brings back me to the screen and the cursor
    • Activate the video mode low resolution which brings back me to the black screen and a cursor
    • Using Ctrl + SHIFT + ESC to appear during the black screen Task Manager
    • CTRL + Alt + Delete does not work on the black screen
    • I do not have access to the installation CD, as it was preinstalled on the computer

    Yes, as usual, what happened after a windows update - I really should stop waiting for something good to these updates.

    I'm under the original version of Vista Home Premium without service pack - these caused a similar problem, but at least I was able to return the system restore.

    Thank you in advance, I know how useful these forums can be.

    Yes, a new installation of Windows 7 was the way for me. Lucky he composed a back all my documents, however. Thanks for the help all. Unfortunately I have no where near more closely to solve the problem, then when I started.

  • Satellite A100 system goes to a black screen after the recovery procedure

    I tried running the recovery CD, I received on my cell phone. the process perfectly, (I have only one CD, I don't know if I need a second). At the end of the process, I have the option to insert the second CD, or jump.
    Because I don't have that one CD I have support on ignore.

    I tells me that the installation is complete and I can restart my system.
    Then I removed the disk and I tried to reboot the system. The system goes to a black screen (on which he indicates that Microsoft load) and then crashes. That was the problem I was facing before recovery.

    Basically, the recovery process has not worked. I don't think I did something very wrong, unless I need a second CD. What could be the problem?

    Help me please!

    Hello

    The A100 is one of the new series of laptops and AFAIK the image of Toshiba was placed only on a CD (DVD) recovery.
    I think that the message and the possibility to insert the second CDconfuses a little.

    In my opinion the black screen and freeze has nothing to do with the recovery procedure and the new installation if Windows OS.
    Due to the fact that this problem has occurred until you have installed the OS from the recovery CD, I assume that there must be something wrong with the hardware.

    But it s very interesting to know if the same problem appears after the new installation of Windows from the original CD of Microsoft.

    It's worth a try.

    • Find the Display card Driver.

    • Select the check box delete the driver for this device.
    • Restart the computer after the uninstall is complete.

    Step 2:

    Uninstall the drivers of device from the list of programs in the control panel

    • Click Start, select Control Panel
    • Now, click on programs and select programs and features.
    • Find the Display card Driver.
