    Here is what I did.

    Boot to third party as long as the system drive will be accessible.

    Check windows update log, copy all that update last March 2, 2012 since that was the the date when we get blue scree.

    Here are 2 KB that I've seen.

    KB2532531

    KB2555917

    Out of the 2 in reference to Microsoft Support site I saw:

    MS11-054: Vulnerabilities in Windows kernel-mode drivers could allow elevation of privilege: July 12, 2011

    http://support.microsoft.com/kb/2555917

    Describe about the file: 

    Win32k.sys

    I went in the system drive search all folders with Win32k.sys inside systemroot.

    Check the date created for the file Win32k.sys (March 2, 2012) windows\system32

    Found that there is another file that was created Last July 2011.

    Go to system32 and rename Win32k.sys to zWin32k.sys as what I always do back in PC SAFETY days(I miss you guys!!!)

    Paste the new copy inside the system32 (one with july 2011 created date)

    Restart machine.

    Yah Lah!!!

    Can now boot....

  • Booting up to start-up repair. Opening a cmd prompt and typing this command fixed the problem for me.

    dism.exe /image:C:\ /cleanup-image /revertpendingactions

    After entering this in and rebooting, windows updates performed a "reverting changes"   I am now able to log into windows and everything is working correctly.

  • Mt screen is frozen and allows not typing in whatsoever.  I also tried the reinstallation CD and it never came on screen.

  • I searched through a lot of places and found nothing that would've suggested anything like this.

    But this worked perfectly and corrected the problem instantly.

    Much appreciated!

    I actually signed up just to make this comment.
