Possible KSOD (blacK Screen Of Death) Solution for Windows Vista

A few days ago, my Windows Vista on my notebook started to have the KSOD (blacK Screen Of Death) syndrome. This syndrome is that after typing your username and password on the login screen, you are presented with a black screen and a mouse, nothing else. When searching on the internet for solutions I found out that quite a few people experienced the same issue with all kinds of different solutions. I tried some suggestions like System Restore, file system check, registry changes etc etc, but nothing was working for me.

When you are presented with a KSOD, you can try to press the left SHIFT button a few times to trigger the sticky keys feature of windows. This will popup a window that contains a link. You can then click this link and from there you are able to launch different applications. Of course, if you disabled sticky keys, you are out of luck…

After wasting almost a whole day on trying everything I could think of, I stumbled upon a blog where they said that it might be related to the eventlog. To test this, I wanted to disable the eventlog. Unfortunately you cannot disable the eventlog from a running Windows because some other services are relying on it. I booted into “safe mode with command prompt”, because normal safe mode would also give me the KSOD. I disabled the eventlog and rebooted the machine and to my surprise everything worked :)

The next step was to delete all eventlog files from C:\Windows\System32\Winevt\logs, switch on the eventlog again, reboot and everything was again working :)

    Worked for me…
    All operating modes gave me the KSOD. I had to:
    1)Go to recovery mode(press f8 at startup)
    2)Choose comand prompt from the list
    3)Type in c:
    4)Then type in Regedit
    5)Clicked “File>Import”
    6)Clicked to show “all files” at the bottom
    7)Surfed to C:\Windows\System32\Winevt\logs
    8)Deleted all event logs one bye one.

    closed all windows, clicked on restart and was done. I am operating on a Dell Studio with Windows Vista.

    Thanks Guys!

    Rowedahelicon, i saw that post of yours several months ago and so far its worked on ever KSoD case ive had. In return ive been re-posting your original to spread the word about it. In general its reletivly simple but unless you know what your doing it can be confusing. When ever i get one in i try other methods besides the sticky keys solution (incase i get one where its turned off). Only other method i have is to boot into SLAX (lynux on a jump drive) and navigate your way to the log files in system 32 and delete them. If the bios doesn’t support usb booting you can also hook up the hard drive as a slave on a stable system and do the same. I understand that not everyone has access to this but it works none the less. Thank you for your original solution!

    Note that I’m not taking credits for this solution. I just found it myself after searching the net a few hours, the link is in my post. Since it took me so long to find the solution I thought it would be nice to also post it on my blog to increase likelihood for others to find it :)

    here is a new solution for the Black screen of Death.
    Using the ultimate boot disk tools, used explorer to access the registery directory at C:|windows\system32\config\ found two registery files “software” and “software_previous” I renamed the “software” file into “software_corrupt” and the “software_previous” to “software”.
    Guess what! it worked.

    If not, it might be your screen that is broken…

    THANKS to Marc for this blogthread!

    Currently bashing a client’s notebook with VIsta KSOD bad bad
    No combination of recovery disk or boot sequence “fixer” works,
    can get command line in safemode, but have no rights to delete things.
    Best I could do there was msconfig to lean up startup.

    Have now booted the latest Mepis live disk and been able to delete any and every i choose,
    now THAT’s FREEDOM, as in free software.
    It’s rebooting now… hang on….

  15. Marc Gregoire said,

    The pressing SHIFT key 5 times is a feature called Sticky Keys in Windows. If you have disabled the Sticky Keys feature in Windows you cannot use this method. Unfortunately, I don’t know of another way.

    Thanks Mark Gregoire after trying many solutions I stumbled across this and it actually worked! Kudos on re-blogging this I encourage anyone experiencing KSOD to try this fix.

    Only difference I tried in my case is renaming Logs to Logs.old and creating new Logs folder.

    UBCD4WIN also helps a good deal for any unfamiliar with command line.

    I fixed my black screen problem by realising that the bios boot section had moved my usb drive to the main boot drive. the only way to get around this is to disconnect all usb devices (leave keyboard attached) boot the comp 1 – 5 secs go into your bios make sure that the main boot device is the hard drive with windows on it, save and boot again and it should load windows (7) in my case, if not then boot and 1 – 5secs in press F8 and manually choose your hard drive to boot from, I realise that differnt motherboards have different keys to press, but they all should allow you to choose which hard drive to boot from manually. After you get into windows create a back up and then fix the comp with windows repair and it should successfully rewrite the boot commands again. I hope this helps.

    I don’t have the KSOD-problem, but if you accidently disabled SHIFT sticky key, then there might be one other way to explore your computer… Press control+alt+delete and enter task manager. Once you did this, click on the butten ‘New Task’ and typ in ‘C:\Windows\explorer.exe’. Now you can explorer your computer and edit everything they sad here, but, like I sad, I don’t have the problem and I don’t know if you have any acces to the task manager.

    None of the usual tricks worked for me. Here’s what worked for me (caveat that I’m glossing over steps here):

    (1) Boot from your installation CD and choose Recovery Console.
    (2) Use the “listsvc” command to list all services.
    (3) I started with AVG antivirus, disabled about 6-8 services related to it using their names from the “listsvc” command and using the “disable XXXX-service-name” command for services, then rebooted to see what happened.
    (4) Reboot worked fine, no KSOD, so I uninstalled AVG, and then re-installed another antivirus.

    In my case, it looks like the users had older AVG installations that were EOL’d (plus they’d just installed new versions over old versions over the years). Hope this is useful to someone else because when Safe Boot doesn’t work, well, you’re left with very few options. And I’m too much of a geek to just reinstall without learning what is really happening.

    I have to reboot my PC up to 6-7 times before Vista starts up. I can’t delete the files in :\Windows\System32\Winevt\logs. Every time I try that Vista tells me the action can’t be completed before the file is open in another program. Via cmd I can’t get access to \Winevt which is strange.

    You cannot delete those files as long as the event log service is running. So try to disable the event log service as described in this blog post.

    As mentioned in my post you cannot disable it from a normal running windows.
    You need to do it from safe mode with command prompt.
    The command line to disable it is:
    net stop eventlog

    In my case…nothing seemed to work.
    I couldn’t get to any version of SAFE MODE…
    ======
    I found a couple or three blogs which mentioned three files.
    c:\windows\EXPLORER.exe
    c:\windows\system32\TASKMGR.exe
    c:\windows\system32\WINLOGON.exe.
    I did not have a VISTA CD available & found a VISTA recovery
    program on the web. It gave me screens & allowed me to run
    SYSTEM RESTORE & run a DOS prompt.
    I found another computer running VISTA & made copies
    of the three files above.
    ======
    I ran the RECOVERY disk & went to a dos prompt.
    I made a renamed the first file (something like explorer.old).
    Then copied the version that I took from the working computer.
    I noticed that the two files were not the same size.
    When I rebooted the system, some things started to work but it was
    still not working properly.
    I ran the RECOVERY disk again & renamed the second & third files.
    Then copied the files that I took from the working machine.
    The third file was a different size.
    TASKMGR.exe was the same size & when I ran a file compare
    (FC firstfile secondfile), they were identical.
    This time when I rebooted, the system came up.
    Subsequently, the system was operating nominally.
    In my opinion, I found two files that became corrupted.
    In my case, I thought that this was the case because the computer
    was experiencing power problems. The laptop’s battery was dead & the
    AC supply had an extremely bad connection. So it was quite likely
    that the computer was going on & off at random.

    Hi.
    As this site is the number two Google hit for “KSOD,” I will post my successful resolution of a KSOD here. I hope that you can edit your original post to reflect some of the evolution of the KSOD since you first encountered it.

    I had two machines with KSOD. One occurred before the login, the other after login. The one that had the ‘early KSOD’ gave me no joy. I mounted up the drive in a second system.
    I ran chkdsk /f — no joy.
    The winlogon value was explorer.exe — no joy
    The RpsSc value was the correct network one — no joy
    No restore points were available.
    Safe mode was not available
    Msconfig cannot be run from the recovery environment
    Sticky Keys and CTRL-ALT-DEL -> taskmanager do not work.
    I reworked the registry from the RegBack directory.
    I renamed the winevt logs.
    No Joy.
    I copied off the important data and reformatted.
    If there is a cure for ‘early KSOD’ I don’t know it.
    Neither does MS Product Support, who I called for only the third time in a decade as an IT professional.

    The ‘late KSOD’ unit is a different and more joyful outcome.
    CTRL-ALT-DEL -> taskmanager DOES work.
    Safe mode worked.
    Then things got tough.
    SFC wouldn’t run
    Explorer wouldn’t run
    msconfig wouldn’t run.

    But cmd would run
    AND Regedit would!

    Disable UAC -> regedit
    HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System
    Key EnableLUA give it a value of 0

    Enable the administrator account.
    You might have to reboot after disabling UAC to get a cmd prompt that will work (sufficient permissions)
    At the cmd prompt –> net user administrator /Active:yes

    Now we’re starting to cook with gas.

    Boot up into normal mode.
    Try logging on as administrator.
    My first attempt didn’t play…BUT

    Logging into safe mode ->msconfig ->diagnostic start

    got things going.

    Log in to administrator in Normal Mode
    Now run cmd -> sfc /scannow.

    Lots of errors it says. Check C:\Windows\Logs\CBS\CBS.log
    Searched for ‘failed’
    Lots of files!
    Almost all in c:\windows\softwaredistribution

    Bingo!

    That’s the windowsupdate files.
    I am in diagnostic mode, so I can rename SoftwareDistribution to SoftwareDistributionOld.
    For good measure I rename C:\Windows\System32\winevt\Logs to LogsOld and create a new Logs folder.

    Boot up in normal mode.
    WindowsUpdate won’t play
    Error 80072EFD — firewall issues
    But Windows Firewall is off…hmm

    cmd -> netsh winhttp reset proxy.

    Windows Update now works.
    So does IE

    This unit was only SP1 — so I downloaded the full SP2 package.
    Installed it
    And then every other myriad update it didn’t have.

    Turn on UAC
    Turned off the administrator
    cmd -> net user administrator /active:no

    Logged into the original profile
    Installed Flash 10.1

    All good.

    Call to MS Product Support — $59 (waived as a Windows Update issue)
    Fixing a KSOD — priceless

    Hello all,

    Maybe I’m doing something incorrectly, but I’ve tried a few of these without success. The same symptoms persist:
    Black screen after logging in, can access task manager, can access safe mode, dont’ have explorer.exe running, etc….

    I deleted my event log, and MBakir’s suggestion was to rename Software_previous to software and rename Software to Software_corrupt….except I only have one Software in Windows/system32/config, so i don’t know where to go with that one.

    I also did Nick67′s idea only to find my BLACK screen of death had changed into a Pale BLUE screen of death with the same symptoms (not the old school blue SOD with the error message displayed). And when I get to the step “sfc /scannow” it won’t let me.

    So what now?

    1. Right-click Taskbar (or CTRL-ALT-DEL) and select Task Manager
    2. File > New Task (Run) > Regedit
    3. Disable UAC
    HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System
    Key EnableLUA set value = 0
    4. Enable the administrator account.
    File > New Task (Run) > cmd > net user administrator /Active:yes
    5. Diagnostics Mode
    File > New Task (Run) > msconfig > select Diagnostic Startup > Ok > Reboot
    6. Logon as Administrator
    7. Rename c:\windows\softwaredistribution to softwaredistributionold and create new softwaredistribution
    8. Rename c:\windows\system32\winevt\logs to logsold and create new logs
    9. Boot up in normal mode
    10. Run WindowsUpdate
    11. Turn on UAC
    12. Turned off the administrator
    cmd > net user administrator /active:no

    Done.

    I am sorry to sound like a novice, but my Systemax (asus 5gpc MB) Running Vista will not let me past the dreaded “Loading windows files” screen. My Bios screen pops up, but I cannot even get it to recognize a boot request from CD (I only have drivers, pre-installed Vista). All requests (safe mode, etc.) lead to Loading Windows Files, then NADA! Ctrl/Alt/Del gives nothing but “Loading windows files screen. I cannot access hardware, safe start, and have no Vista disc for reinstall. Tried ultimate boot CD, but it would not recognize CD drive for boot. Can anybody help?

    Wrote on January 20, 2011 @ 6:49 pm

    If your machine does not recognize the CD drive for booting, it probably means something is wrongly configured in the BIOS. Try to enter you BIOS. This is usually done by pressing DEL or some other key right at the beginning when the PC starts. Then you should try to browse the BIOS settings and find somewhere something called boot sequence. There you should be able to add your CD-Rom to the boot sequence.

    KSOD for two days now and going insane :( Here is the info, if anyone has any suggestions I would be so greatful!

    HP Pavilion laptop (dv4), originally Vista 32bit. Had been upgraded to 7 through the upgrade program. Came to me with a Win7 repair disc (not recovery discs)

    Needed to get back to Vista and did not yet know there was an HP tool for this, so stupidly followed these directions found all over the web (legit but turns out NOT for use with upgraded units, only clean installs I believe – since there is no “full” Vista OS to revert to)

    http://www.intowindows.com/how-to-downgrade-from-windows-7-to-vista-step-by-step-guide/

    C:
    Md Win7
    Move Windows Win7\Windows
    Move “Program Files” “Win7\Program Files”
    Move Users Win7\Users
    Attrib –h –s –r ProgramData
    Move ProgramData Win7\ProgramData
    Rd “Documents and Settings”

    move /y c:\Windows.old\Windows c:\
    move /y “c:\Windows.old\Program Files” c:\
    move /y c:\Windows.old\ProgramData c:\
    move /y c:\Windows.old\Users c:\
    move /y “c:\Windows.old\Documents and Settings” c:\

    D:\boot\bootsect /nt60 c:

    First section went fine. Second section was fine except for the Program Data and Users – both came up with “not found”. Googled this, and other people w the same tutorial said to just keep going if that happened. Also, I mistakenly put in D: as the text lists, not E which is my dvd drive.

    Now – the laptop boots up, I see the XP logo, Windows logo with the bar going left to right…but then goes to ALL black with a cursor and that’s where it stays. Cursor is movable, but nothing else. CT alt Del and shift 5x does not work. Same thing with safe mode, sm with CP or NW. After a few minutes, I see the default screen saver come up, and occasionally a second of the four corner text in safe mode comes up but then goes away.

    I put in the repair disc and can view that fine – screen is normal.

    Memory check comes up fine, and the repair option says “no errors” Restore has no point to go back to, and image recovery – no image found/have none saved or on disc.

    Command prompt, which is where I entered the stuff to begin with that messed this up, is the only option left really I can work with. I did get
    into the regedit menu as people here suggested and followed those directions, but this did not work either. Don’t know what else to do with regedit so leaving it alone for now. HP doesn’t carry the 32bit recovery discs and all I have here is a set of 64bit ones.

    Also, not sure if this matters, but when running the repair disc, it finds two entries for windows – windows 7 and windows 7 home premiums. Both identical partition size and on C:local disc. First option must be Vista as choosing that gives “this version of system recovery options is not compatible with the version of Windows you are trying to repair” However, it still saying Windows 7 means I messed something big up, I suppose! It does have a “load drivers” button that seems to work.

    Any help would be greatly appreciated!

    Thanx MBakir! Your solution worked fine for me.
    Rename windows/system32/config/software_previous to software.

    M. Bakir had the answer to my KSOD problem this time as well. I had this once before, but can’t quite remember what the solution was. I think it was the clearing of the log files, since I had a folder named Logs_bad in addition to the Logs folder. Of course I tried that solution this time without success, so it may just have been from a failed attempt. I didn’t use the previous_software file since it was dated 2006. I found a folder created by System Mechanic which backs up my registry and had a software file dated 9/2010 which is probably pretty close to when the pesky KSOD reared its ugly head this time around. Mind you, it didn’t take me that long to fix the problem, I just gave up for awhile and used my backup PC. Every now and again, I would take another crack at fixing it. I’m now in the process of updating software and running System Mechinic to get another good backup of my registry. Many thanks to all who persevere, especially M. Bakir.

    I finally found a way to get the desktop to show after login on Vista.

    1.Go to Start –> Run –> Regedit
    2.Find the following key:
    HKEY_ LOCAL_ MACHINE, SOFTWARE, Microsoft, Win­dows NT, CurrentVersion, Winlogin
    3.On the right hand pane, find Shell and double click it to edit its value. Its value should be explorer.exe only.

    Mine had the explorer exe and winlogin exe or something. I deleted the winlogin one, leaving only explorer.exe and it worked. Thanks goes to Duno http://www.technize.com/my-documents-folder-opens-at-windows-startup/comment-page-1/#comment-73588

    Mine looks overcomplicated than the problems u guys got. Avg antivirus captured some system files including winlogon. I used winxp boot disk to repair the captured files. During repair, with 2 mins remaining, there is power failure and i had to restart the repair process again. Thinking that the power is okay, i tried again and with 25mins remaining, power failure occurs. Not risking another power failure, i powered up my generating set and tried the repair again from beginning. After the repair consule has copied the files it needs to use for repair, system reboots, windows xp loads and then the blacK screen with only cursor shows, preventing the repair. Tried every idea u guys have posted but nothing. I dont wanna format cos of important family photos and videos. HELPPPPPPPPPP

    You should at least be able to access your files throught the windows recovery console.
    Or maybe you can connect the drive to another working machine to copy all data from the drive.
    NOTE: you should *always* have offline backups of your data. Never trust a harddisk.

    NONE of these have worked. I have repaired the registry using a program, done all the fixes listed here… I do not have or cannot find my disc and I do not have any recovery points.

    A little more info..

    I have Windows Vista Home Premium.
    The kid had an annoying popup so he used my admin password, then the black screen… dang kid
    Found and removed a virus, which is why I started with the registry repair first.

    check disc, malwarebytes, and spybot come back clean

    Tried all the fixes above, logs are changed, softwaredistribution is changed, etc. nada

    any other ideas folks? Thanks in advance!!

    Hi,

    changing the software_previous to software worked for me

    I was a bit confuse if it was in regedit or directly in directory (tried many linux livecd)

    Finallly I changed the files in the directory [C:/]windows/system32/config (which is not necessarily accessed via a regedit software)

    Bactrack 5 worked for me using the commend prompt:

    fdisk -l (to check if C or system disk is an NTFS disk and its name)
    mkdir /mnt/windows (create a “shortcut” folder into which mouting the disk)
    mount -t ntfs /dev/sda2 /mnt/windows (to mount the disk: for me, C: is named /dev/sda2 accoring to fdisk -l)

    then in /mnt/windows i had the same directories software and software_privious that Mr. Bakir, so i did the same and it worked!

    For the Linux commands explanation in backtrack, check this video: http://www.youtube.com/watch?v=lsGlnhF7JbE

    Good luck :)

    mv (to rename a file)

    here is a new solution for the Black screen of Death.
    Using the ultimate boot disk tools, used explorer to access the registery directory at C:|windows\system32\config\ found two registery files “software” and “software_previous” I renamed the “software” file into “software_corrupt” and the “software_previous” to “software”.
    Guess what! it worked.

    if it worked for you join my network

    After spending 2 days trying to fix this issue for a friend of mine’s Vista 32 bit laptop, M. Bakir’s solution worked like a champ! Instead of software.previous, I had to use software.bak. Still worked perfectly.

    Thank you SO much!!!

    I ploughed my way through various fixes on this site and others and to no avail. I was about to format the drive and start again when I did one last thing which was the PREVX fix I think and it appeared to work – until my son touched the top of the screen and it went black again. After all that effort (15 hours+ probably over 4 days) it was the screen cable into the back of the pc! I know, a stupid mistake, but in my defence the screen worked fine for the BOIS parts and the SAFE mode. I recken there were just enough pins connected to work the screen with 800X600 but when it finally went to the 1200X1600 or whatever when the windows desktop opened the last few pins on the connector weren’t in enough and it went black. Don’t want anybody else to forget this early in the list check.

    Cheers,

    Hello from “The Future” :) Well, I was at a loss with W7 KSOD – tried a stack of things that had previously worked on other machines and had to say that M Bakir’s fix – posted way back in 2009 and for Vista – actually worked for W7 in 2013. To get the fix done quicker and easier I would add two options:

    1. Use Hirens Boot Cd / Mini Windows XP to do the file moving / renaming.
    2. In W7 the two files are actually in different folders – they are both called software – the one in //system32/config/RegBack should be copied to //system32/config and overwrite the file there.

    AOK now – I was about to assume it was the graphics fried or some other hardware issue as all else had failed.

    Thanks M Bakir
