Vista Black Screen Blinking Cursor After logon

    I am the supervisor of a Help Center on a college campus, and work on
    students' computers as the students have issues. I don't always know what
    happened immediately before the issue appears. This one has me stumped. Here
    is the data:
    Dell Inspiron 1525 (Celeron)
    Vista Home Basic
    2GB Ram
    Bios Date 6/2008

    Problem: Computer boots to logon, accepts password, appears to be loading
    Vista, then comes to a black screen with an arrow.

    Other: Does the same thing in Safe Mode. Control & Alt & Del do not work

    Tried and failed solutions:
    Diagnostics - ok
    Repair from CD
    Chkdsk /r command
    Restore to earlier date
    Booted to Last Good Configuration
    BootRec /rebuildbdc command
    Reset Bios
    Reseated Memory and switched it around
    Booted without Power Cord
    Disabled USB in Bios
    Disabled 1394 in Bios
    Read through Dell Forum

    One thing I couldn't get to work was to change the winlogon shell registry
    item to explorer, through a command prompt. The path is
    HKLM\Software\Microsoft\WIndowsNT\CurrentVersion\Winlogon. I tried to change
    the value data frm cmd.exe /k start cmd.exe to Exploer.exe, BUT every time I
    restarted the machine it reverted back.

    Any ideas? I have the data backed up, ready to do a system restore. Sadly, I
    have seen this several times, and would love to find a fix for it.

    Thanks to anyone who can help!

  2. Try tapping F8 just as Vista begins to boot up. This will take you to the
    advanced boot option menu.

    You can try booting with the last known good configuration. This may get you
    in. You can also try again using low resolution booting - in case someone
    has set the Window resolution above the capabilities of the video system.

    Let us know how it works out.

    Actually, I have tried to use the lower resolution to boot, as well as the
    advanced boot options, also, tried selecting the option to ignore the driver
    compatibility check with Vista (I don't remember the exact wording.)

    Have you tried inserting your Vista installation DVD and running Startu
    Repair, as detailed on this page
    'We are sorry for the temporary outage.
    (http://www.bleepingcomputer.com/tutorials/tutorial148.html
    How to automatically repair Windows Vista using Startup Repai
    What is Startup Repair? This Microsoft page has a great deal mor
    information about that
    'Windows Vista Help: Startup Repair: frequently asked questions

    Windows Help and How-To: Startup Repair: frequently asked question
    Startup Repair is designed to detect operating system startup problem
    and troubleshoot any found and correct them with little use
    interaction. It can repair problems such as
    - missing or corrupt drivers
    - missing or corrupt system files
    - missing or corrupt boot configuration settings
    - corrupt registry settings
    - corrupt disk metadata (master boot record, partition table, or boo
    sector.)
    When the Startup Repair Tool has taken control, it analyzes startup lo
    files for clues about the source of the problem and launches diagnosti
    tests to determine the cause. If it determines the cause of the failure
    it attempts to fix the problem automatically. After successfull
    repairing the problem, it will reboot the system, and notify the user o
    the repairs, filing a detailed report in the Windows Vista event log.
    If the Startup Repair Tool can identify the cause of the problem, bu
    can't repair the problem by itself, it will provide access to a set o
    tools that you can use to manually troubleshoot the problem further.
    One of these is the Bootrec tool described below
    If the Startup Repair Tool cannot identify or repair the problem, i
    will roll back the system to the last configuration that was known t
    work (Last Known Good Configuration.) Again it will add detaile
    information about the problem to the Windows Vista event log

    I think the above (incorrect value at Winlogon in the registry) is your
    main problem. If Vista Startup Repair doesn't fix it, then I would bet
    that the reason you cannot get the pc to stop reverting back to the
    invalid value is that it is still infected by some sort of malware which
    has a component in the "Run" keys of the registry to reinstate the bad
    Winlogon value. If you can mount the pc hard drive as a secondary on a
    working machine, then a virus check and running of such free tools as
    SuperAntiSpyware could correct the problem.
