    Before reaching the log-in page, I receive an error titled "winlogon.exe - Application Error" with the following message:

    The instruction at "0x75978dc1" referenced memory at "0x00000000". The memory could not be "read".
    Click on OK to terminate the program
    Click on CANCEL to debug the program

    I have clicked on OK, CANCEL and the "x" in the top right hand corner of the message then I receive a FATAL ERROR on a blue screen stating the following:

    "STOP: c000021a (Fatal System Error)
    The Windows Logon Process system process terminated unexpectedly with a status of 0xc0000005 (0x00000000 0x00000000).
    The system has been shut down.

    Then there is no way out of the screen except to hold down the on/off button for the laptop itself and re-start all over again.

    Hi have you made any Hardware - Software changes prior to this happening?
    Reboot - tap F8 as Pc starts up.
    Safe mode with command prompt..
    Log on as administrator.

    This should launch System Restore.
    Choose a date prior to the problem.
