Black Screen delay is 5 minutes after login ??

    Question

  • Since my Vista-to-Win 7 install, I have   e x t r e m e l y   s l o w   boot into desktop. Goes black after login/password and stays that way for several minutes. There must be someone out there that has mastered this huge drawback. Vista was new fresh on a new Dell .. same components, Win 7 chokes.  IsWin 7 that different from Vista in boot process ?

    There is nobody 'out there' who has your machine!  This is not a 'standard behaviour' of windows 7.  It will be occurring because of some condition present on your particular machine.


    First check if a monitor-related misreporting of EDID information is causing you issues.  Right-click on desktop and choose 'change resolution'.  In the dialogue box click on 'Advanced Settings' and then choose the 'Monitor' tab.  What is reported there?  If the monitor is identified as 'Generic Plug and Play' then it would be best to locate a suitable device driver for your specific make/model of monitor, and install that. 

    If Windows is failing to correctly identify your make/model of monitor, and that identification is being left to the display driver, problems can potentially result.  'Blackscreen' hangs or delays would be one potential such problem.



    Alternatively, it could be an installed program which is loading program components at startup and causing such issues.  To troubleshoot, try the following:

    * Press Winkey+R
    * Type msconfig and press ENTER
    *Select the 'Startup' tab

    The entries listed there will give you clues to which installed programs are loading at startup.  Use Google (or Bing, or other search engine of your choice) to help identify which programs those entries relate to.  Alternatively check the directory locations of the entries, to see which programs they relate to.  One by one, uninstall those programs and check to see if removing it resolves the issue.  Programs can be reinstalled afterwards of course.  And if a particular program proves to be the 'culprit' then it won't necessarily need to be ditched.  There may be 'options' settings available which prevent its components from being loaded at startup instead.



    Hope that helps.
    Cheers

  • Hi,

     

    If it works fine in both Safe Mode and Clean Boot, the possible cause should be a third party program or service. You need to finish the troubleshooting steps for Clean Boot to narrow down the cause. After determining the root cause, you may disable or uninstall it to fix the issue.

     

    Good luck!

  • Hi,

     

    In addition, you also can try to update the BIOS and the hardware drivers, such as display card driver, motherboard driver and so on. Then test the issue in Safe Mode and Clean Boot to determine if this is a hardware or software conflict. Clean Boot is the same suggestion as running msconfig Techwrighter provided.

     

    Good luck!

  • Both  SAFE  and  Clean Boot work well ... boots from password/logging to desktop  immediately .. dozens of services to weed thru disable/enable ...  will take days to do trial and error .. Almost listed svcs are Microsoft - how can one determine which MS Svc creates the log-jam for WIN 7 ? .. Non MS are around security (Zone Alarm) and Google Desktop.  Hopefully I don't have to dump these to make Win 7 boot faster.

    No graphics card (onboard graphics/sound) - Intel NIC -- real basic computer (not gaming, office productivity + email + browser).  Passed test for compatibility with Win 7. Monitor, Samsung, Model perfectly ID'd. Keyboard was generic as was mouse.. No trouble with printer.. Belkin MIMO wireless works fine, but maybe it is culprit.   What would delay boot to desktop... Boots fine/quick to Password screen, after that, 5+ minutes watching a black screen + mouse-curser.. very little HD activity.
