    May seem silly, but have you scanned your PC for virus and spyware. You may
    have something running that's causing this to happen.

    Re: Windows Keeps Shutting Down

    I recently downloaded MSI's PC Alert4 for my PC and it has been monitoring my
    PC for about two weeks now.

    One symptom that has cropped up is that the +12V has registered about 2V
    only on a few occasions. So what do I do now?

    I've ruled out viruses and spywares as I've done two clean installs and have
    had the same problem.

    Same Problem Here!!!

    My friend is having the SAME Windows Vista reboot problems. I am trying to help him. Here are the events that seem relevant from this computer:

    The process C:\Windows\system32\winlogon.exe (ComputerName) has initiated the power off of computer (ComputerName) on behalf of user (ComputerName)\(Username) for the following reason: No title for this reason could be found
    Reason Code: 0x500ff
    Shutdown Type: power off

    event id: 1074

    source: USER32

    The description for Event ID 100 from source SDWinSec cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

    If the event originated on another computer, the display information had to be saved with the event.

    The following information was included with the event:


    source: SDWinSec

    ID: 100


    source: winlogon
    id: 6000

    The winlogon notification subscriber <SessionEnv> was unavailable to handle a notification event.


    The Desktop Window Manager has exited with code (0x40010004)
    Source: Desktop Window Manager

    Any help would be awesome!

    Hi, first post here... just been looking into the same issue on a friends laptop - vista premium, all updates, ie 7 and firefox...
    read your post earlier - this laptop was shutting vista down automatically on a few sites and whenever a download was attempted. I created a new account which creates a new profile and the problem does not exist. I probably won't look further oz I have already spent a couple of hours on things like java and flash updates, browser test sites etc. so will just create a new account and transfer data... hope this helps... Many blessings... Chris ) John 3:17

    Update to last post. Before I gave up on the profile I added AVG and it found a worm i-worm.vb-tc I think. AVG deleted one instance which then allowed the original profile to download file from the internet successfully. I then ran a full a scan and it found several other instances which were dealt with. Laptop is fine now.

    Hi ari_ekt,

    You can try to use shutdown.exe to initiate the shutdown. E.g. from the elevated command line run:

    shutdown.exe /r /d P:4:2

    This will result in an eventlog and SEL entry with reason code 0x80040002.

    Shutdown reason codes can be found here:

    Re: Windows Keeps Shutting Down

    Hi EINSTEIN_007,

    and the reason for that shutdown is?

    i read the same here: with link to the same msdn

    but in my case the shutdown was not planned nor wanted. the system with it`s own will decided to fully shutdown the system with no warning, and no error. the log claims winlogon.exe was the service that initiated the process

    compared with the one suggested by you that woks (as well ) good:

    The process C:\Windows\system32\shutdown.exe (computer1) has initiated the restart of computer COMPUTER1 on behalf of user computer1\user1 for the following reason: Application: Installation (Planned)
    Reason Code: 0x80040002
    Shutdown Type: restart

    any, ...other ideas?

    Re: Windows Keeps Shutting Down

    I have 4 computers in my workspace, one tower running Windows xp with updates, a laptop and a tower running Windows vista, and one laptop running Windows 7. For some strange reason, just the computers that are running Windows vista are shutting down randomly. I have run PC Doctor, virus scans, defragged and ran ccleaner on all of the computers. No matter what I have done, the Vista computers still keep shutting down.
