Black Screen after W7 logo before login screen - HELP!

Hi,
When I start windows, after Windows 7 start logo, I get a black screen for about 20-40
seconds, then a black screen with cursor for around 1 and a half minute and then I get the login screen, thats around after 3minutes.
I am facing this problem for quite some time now, I also did a clean windows installation
after wiping out harddisk using diskpart. But it was of no use, still I get that annoying Black Screen at startup and I think my laptop is a bit slow too. When
I open windows in safe mode, I get the Black screen there too but for like 35-45 seconds.
I also ran Dell PC Checkup, everything is fine.
I'd be really grateful if someone helps me find out what exactly is wrong with my laptop
and how can I get rid of this black screen, thanks! 
*Windows is up to date, all drivers are installed perfectly.

Hi,
Did you make any changes recently before this issue? Have you looked into the event viewer for any related recorded information? regarding to reinstallation, are you using a offical installation disc or an image customized by yourself? Any 3 rd party seervices
lauched on startup?
Unplug all the external devices, except mouse and keyboard and then restart the computer.
You can use this small tool Autoruns to check what is launched on a startup

Meanwhile, update driver for graphic card, BIOS and chipset driver will be helpful to improve the performance of your PC.

  • Black screen after boot but before login screen

    Hi,
    I have a windows server 2012 machine running ADDS, recently I installed new hardware in to the machine but when I turned the server on windows would not fully load, in Safe Mode nor normally. So I removed the hardware I had installed but it
    was still like it. The only mode I can boot and interact with the login screen is in Active Directory Restore Mode
    Current config

    I don't see 2012 R2 listed but you'll surely want the proliant support pack installed.

  • Win 7/Z580: Black screen on boot up, before login screen?

    Win 7/Z580: Black screen on boot up, before login screen?
    =======================================
    I find some interesting posting in this forum. Thanks for keeping this forum to help windows/Lenovo community. I like to pick up the brain of this forum to resolve the black screen issue. I am not sure, whether it caused by virus. I use Microsoft Security Essentials. I am not able to run this in command prompt.
    I started my laptop this morning & login screen showed up. Once I entered my login credentials, I heard the sound that usually plays once a login is successful, but I ended up with a black screen. After this occurred, I had to hold down the power button to manually shut down the computer. Once I started it up again, I was prompted to do a system repair, which eventually ended up with all successful outcomes, but I now have a black screen with a cursor before the login screen now. I have no idea what caused this to happen. My laptop is a Lenovo Ideapad Model Z580 (500 GB HD, 6GB RAM).
    I am not able to get into safe mode or any other mode, which all leads to a black screen described above. I am able to use the "Repair Your computer" tools after pressing F8 during booting only . All other options leads to Black screen with cursor in the middle
    Last Known Good Configuration leads to same
    Enable Low Resolution Video (640x480) leads to same My Z580 is not responding to CTRL+ALT+DEL Windows Logo keys as well.
    **** I tried SAFE Mode. It loaded couple of drivers and paused at CLASSPNP.SYS load. It went to Black screen with cursor at center.
    I am able to invoke control pannel from Command prompt of working PC by typing control.
    Z580 PC is not responding to control from command prompt (under Repair Your computer)  either.
    Z580 is able to use the "Repair Your computer" tools after pressing F8 during booting .

    Under Admin user login, it provided system recovery options. It is not picking up the recovery point created a while ago.
    Windows Memory Diagnostics is not launching and shows a black screen without cursor.
    I am able to get into command prompt. I tried the following there.

  • [SOLVED] Black screen halfway through boot before login screen appears

    I originally installed my Arch Linux 64 system on a quad core intel cpu with 4GB RAM and a Nvidia 9600 GT graphics card. Arch is installed on 2 500 GB HDD running on software RAID and LVM. A few months ago I decided I wanted to upgrade my machine to an i7-2600K with 8 GB RAM and a Nvidia 580 GTX graphics card. Since I was using pure software RAID I knew that I could just reuse my installation. So I popped in the drives into the new machine and glory glory Arch booted just fine. One thing I notied though and this has been bothered me since then. On my old machine I could see the whole boot process from start to finish. On my new machine I only see the first few seconds and then a black screen for few seconds and then I get the login screen (KDM in my case). Now I'm running a pure systemd system and I can see the boot process until
    [ok]     started loading random ...
    and then the black screen sets in. Why does this happen? Why can't see if udev, samba etc. start correctly anymore?

    I don't have the nouveau driver installed at all. But I finally got rid of the black screen. I simply added nomodeset to the kernel parameters in grub and now everything ass before.

  • GDM displays only a black screen and a cursor, before login screen

    I'm using the xf86-video-ati driver for an R9 270, and GDM (v3.16.1.1) only shows a black screen with cursor. I can run TWM fine with startx, and I've got 2 displays attached via DVI.

    The first is the audio codec, which is WM Std at 44.1kHz. WVP2 is the video codec and I have not heard of it. Nor seen it playback in QT assisted by Flip4mac so it may be unplayable.
    There are always listed one audio codec and one video codec in that box assuming there are audio and video in the clip, e.g. AAC 256 bit (audio) and H264 Simple Profile (video) in an iPod clip.
    Ooh bad news, from another source:
    +"It seems that the Flip4Mac WMV Player, which should provide the missing Windows Media support for Mac users (as endorsed by Microsoft) does not support all Windows Media codecs, namely *it refuses to play content encoded with the Windows Media Video 9 Image v2 (WVP2) codec.* "+

  • MSI R9 270X - Black Screen after Win7 logo

    Hello there.
    About a week ago I upgraded my PC, buying several components and putting it to work. Here's the specs.
    Main Board: M5A97 EVO R2.0
    Bios Version: Latest
    Video Card: MSI Radeon R9 270X TwinFrozr OC Edition 2Gb
    PSU: Don't know
    12v rail Rating of listed PSU:
    CPU: AMD FX 8350 4.0Ggz BE SkAM3+
    Memory: 8Gb Crucial Ballistix DDR3-1600Mhz
    SSD/ HDD: Western Digital WD10EZRX-00A8LB0 1TB
    CPU COOLER: The one that came with the CPU
    Raid Card: Onboard
    Sound Card: Onboard
    OC: (Yes / No) Don't know
    Operating System: Win 7 SP 1 64
    So, it worked just fine for about 3 days. Last Saturday night I tried to open Google Chrome after some gaming and the the system froze. I got a screen with vertical black and white stripes. I had to reboot the system and it gave me a black screen, crashing again, after the Win Logo at start up. At this time I was running either 14.7 or 14.9 ATI drivers.
    I could only start the PC on Safe Mode. Removing the drivers and getting Windows general VGA card settings would allow me to use Windows in normal mode though. Once I installed the Graphic Card's drivers it crashed on reboot, always with the black screen after Win logo. I installed several ATI drivers, namelly 14.9, 14.11 beta, 13.12... and nothing worked.
    I flashed the Mother Board BIOS to the latest version, formatted the HDD doing a fresh install of Win 7, installed Catalyst first and then the drivers, the drivers without catalyst, etc. and nothing worked, always getting a black sreen on reboot once the Graphic Card's drivers were installed. I even swapped the Graphic Card to a different slot to no avail.
    Right now I'm using my old Radeon HD 5670 with the latest drivers and everything works just fine. It even works fine if I keep both Graphic Cards installed with the monitor plugged to the older card. I find this odd since to do so, Windows loads both cards drivers with no errors. But once I switch to the new card everything goes black.
    Can someone help me out? I've tried to contact my vendor's technical support through mail but they're not answering. I fear that I'll have to report it as DOA and swap it out, which will take quite some time taking into consideration the way things tend to work around here.
    EDIT - I don't have a 2nd system to test it on.

    Nope. Not driver issue at all. I tested at least 3 different drivers, all with the same result. Besides, I used both Driver Fusion and Driver Cleaner and CClean to remove any non-deleted registry entries. Always got the same problem. Went as far as formating the drive and doing a clean Win install. The problem persisted.
    Tried installing drivers without Catalyst to no avail. Tried installing Cataltst first and then the drivers. Nothing. It always crashed omce the drivers were installed.

  • Hello my MBP 15" stops at grey screen after apple logo disappears

    hello, my MBP 15" stops at grey screen after apple logo disappears, what can i do about this? ive tried booting into safe mode but screen turns blue with black lines also tried resetting NVRAM and PVRAM but still stops at grey screen, also tried using applejack, it shows no problems at all, says my disk volume is ok but the screen still stops at grey during start up, havent tried the installation disk thing because i dont have my installation disk with me

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    Step 1
    The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.   
    There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
         a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
    b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
    Step 2
    If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use either of the techniques in Steps 1b and 1c to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
    Step 3
    Sometimes a startup failure can be resolved by resetting the NVRAM.
    Step 4
    If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
    Step 5
    If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
    Step 6
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
    Step 7
    If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
    Start up in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Post for further instructions.
    Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 10. If you ever have another problem with the drive, replace it immediately.
    If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
    If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 8
    Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
    This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
    Step 9
    Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Step 10
    Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
    Step 11
    This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
    Step 12
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

  • White screen after apple logo

    Hello
    i have big problem with my MacBook Pro 15 (2011)
    when i start up my macbook after apple logo show White screen , and i'm trying start up with safe mode but still white screen
    i'm try every solutions in site
    This I’ve done so far:
    1) I started in safe boot (holding shift) but that only takes my to Darwin/BSD logon screen. It asks for at username, but I can’t type in the following password.
    2) I tried single-user-mode. I did “fsck” and it told me “everything appears to be ok”. Also tried: mount -uw / etc and that didn’t do it either.
    3) Tried to boot from MacOS CD installer. but Still blue screen
    4) I did the “option+command+r+p” – nothing.
    Please help me to solve my problem
    Regards,

    Reinstall Lion, Mountain Lion, or Mavericks without erasing drive
    Boot to the Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
    Repair
    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu.
    Reinstall Lion, Mountain Lion, or Mavericks
    OS X Mavericks- Reinstall OS X
    OS X Mountain Lion- Reinstall OS X
    OS X Lion- Reinstall Mac OS X
         Note: You will need an active Internet connection. I suggest using Ethernet

  • Initial Message before login screen

    I am facing a problem,
    I need to display a message once before login screen, the message will be more than 200 characters I tried to use Alert and message builtin but the limitation was that only 200 characters can be displayed thru these builtins, therefore I am unable to display the message.
    How Can I do that ?

    You could null out the on-logon trigger and call your own Form which displays the message and the calls Logon built-in.

  • IMac seems frozen in that following start-up, sun flower just keeps spinning on a blank screen (only Aplple logo on white screen)

    IMac seems frozen in that following start-up, sun flower just keeps spinning on a blank screen (only Aplple logo on white screen).  Turning off and on not helpful.  Any ideas?

    What  iMac is it and what version of OS X are you running?
    Try an SMC reset: https://discussions.apple.com/docs/DOC-3603
    If that doesn't help, try a Safe Boot: restart holding down the Shift key until you see a grey progress bar - you'll need to input your admin password during boot-up - and once booted, restart as normal from the Apple menu.

  • Please Help: iMac black screens after startup logo + spinning wheel no cursor).

    Hi, guys.
    I'm in a fair bit of a desperate situation; my iMac's screen seems to shut down every time after the white startup screen. The Apple logo appears, & the progress wheel begins spinning, then after a while - when it would usually then go to the gray login screen - it would, instead, go black. I can tell that the machine is still on (I can still hear it clicking as it does during processing) but I'm unable to determine anything else. Nothing is visible on the screen - not even the cursor - it's as if the display had turned off completely. I'm not sure if the login screen sits beneath that black screen (I have tried to log on by typing my login details in blindly, but even if it does log in, it's hard to determine what state the computer is in without seeing the screen.
    I have tried the PRAM reset (holding CMD+OPT+P+R) during both the white startup screen, & the black screen to no avail. It seems unresponsive because I don't hear any additional chimes that I've been told should be heard during a PRAM reset attempt. I can't even be sure that the command is being inputted correctly because the light on my wireless keyboard remains off during the process.
    I've tried rebooting over & over again; the results are the same.
    The steps that led to the problem occurred thusly:
    1 - I was trying to clear some memory from my current session, so I scanned through my active processes, quitting anything which seemed to be eating up considerable amounts of memory.
    2 - One particular process I quit was 'launchd' which was functioning under my profile username.
    3 - After quitting launchd, all opened apps seemed to close, & it looked like I was forcibly logged off the machine. The screen froze during this point, & I decided to do a hard reboot to log back in.
    4 - The problem began after this hard reboot; startup seemed to occur as per usual; white screen > apple logo > progress wheel > and then suddenly, a black screen where the login screen should be.
    I've shown a flashlight into the screen while it's black & it seems well & truly like the display has shut down while the iMac continues in the background. I have had issues relating to my screen going black before, but they were random & intermittent; they didn't occur without fail during the exact same time immediately after startup, & could be remedied by using the CTRL+OPT+EJT keys.
    I am on an iMac 2010, 27", using I believe Lion OSX. I am unable to recall additional specifications while the problem persists.
    Could anybody please help me? I'm quite desperate; I was in the middle of some urgent work that I need to get back to as soon as possible.
    Thank you I'm advance to anyone with advice on how I can go about fixing this.

  • Acer XB270HU black screen after windows logo for about 20-30 seconds

    Hi all,On a fresh and fully up to date OS (Win 7) with 2x GTX 980 Ti I have an issue where the screen goes black (No Signal) just after windows logo. Im using UEFI SDD boot flow, have secured boot disabled. Im connected with DispayPort 1.1 (not sure if that matters). This issue did not occur after getting to Windows just after the reinstallation of the OS (no drivers, no updates). It started to occur after the OS got fully up 2 date. Any ideas? As Im losing 30 seconds on boot-up with UEFI so it feels like IDE....

    I also have the same issue, it only started a few days ago and ive had it for 2 weeks. Sometimes when I start up the computer, it will say no signal and my secondary monitor will turn on and take its place as the primary monitor. A restart will fix this issue, but then my Acer goes black, says no signal, comes back at a resolution of 600:800 and then 1920:1090, and changes again to its native 2560:1440.
    Not to mention G-SYNC does not work at all on my monitor. I can't beleive they charge $1,000 for this extremely mediocre at best monitor

  • Black screen after windows logo problem

    Hi people, i have the HP Probook 4530s LH306EA and i have been using it for 3 years without any problems but this week after i did a restart on my laptop i got a black screen after the windows logo.
    The problem is whenever i install the AMD Display driver it says that there were some errors during the install and the pc freezes and restarts into a black screen...
    AMD Display drivers 13.152-130830A-162882C(18 Oct 2013)
    Windows 8.1 64bit
    Is there any solution to this or some other drivers?

    you wouldn't by chance be attempting to use a Sandforce controller using SSD?
