    I have no idea if its a malware or what. It does it once a day,yesterday it was about 3:30 pm today it was 11:30 am its done it at 9 pm and I have windows update service disabled on the msconfig startup.

    Please walk me through how to go about this. Should I post a hijack this log, a log from the event viewer (please give details on how to do this) .

    Im at a loss on this typpe of issue but I need help so anyone interested please take some time to chip in and get me started.

    Thanks everyone.

    This may stop restart.
    Start - Control Panel - Open System Icon - Advance System Settings (at the left top corner) - Advance Tab (at the top) - Startup and Recovery Block click Settings -
    Remove the check mark for - Automatically Restart- OK If needed Click Apply - OK
    If now your computer restarts and you get a blue screen write the error number down
    and go to Microsoft Knowledge Base and do a search for information for the cause of
    your problem.

    Create a Windows 7 Repair Disc
    Start - Control Panel - Backup and Restore - at the left top corner -
    Create a System Repair Disc - It may say DVD but a CD works OK

    Computer Repair
    Put System Repair Disc into CD - DVD Tray
    Restart your computer - Be ready to press any key when asked.
    If you don’t press any key in time, windows starts normal.
    Windows is now loading files.
    Title of new screen is - System Recovery Options
    If selection is correct click - Next - Next - Startup Repair
    If it finds something wrong it may repair at the beginning.

    hijackthis can be downloaded here.

    When using click - Scan and create a log. Notice were the Log is saved.
    It may go to your Documents of your Desktop.
    You open - Select All - Click Copy. You paste this log in the Forum for help.
    They are busy so may take a while. For this Forum look to the left top of this page.
    Security and HJT
    hijackthis has some boxes were you can put check marks and remove and item from
    the list. DON'T FIX AND DON'T CHECK MARK ANY THING.

    I wouldn't disable the Windows Automatic Updates.

    ok so far I did step 1, start control panel startup and recovery no automatically restarts.

    Today it just rebooted itself, 11:59 no blue screen. Firefox saved its tabs so Im assuming its not a hardware crash.

    Whats next hijack this or event viewer?

    Did you try this ?
    Create a Windows 7 Repair Disc
    Start - Control Panel - Backup and Restore - at the left top corner -
    Create a System Repair Disc - It may say DVD but a CD works OK

    Computer Repair
    Put System Repair Disc into CD - DVD Tray
    Restart your computer - Be ready to press any key when asked.
    If you don’t press any key in time, windows starts normal.
    Windows is now loading files.
    Title of new screen is - System Recovery Options
    If selection is correct click - Next - Next - Startup Repair
    If it finds something wrong it may repair at the beginning.

    On this Forum only trained personal are allowed to work on a hijackthis log.
    That's why I said go to the left top and click on Security & HJT and put your log their.

    Could be an overheating problem or maybe a power supply problem

    The cpu is idling at 32c and I dont suspect the psu, plus the fact that it saved the tabs I had open for firefox leads me to be pretty certain its not a hardware crash.

    There are a lot of winlogon occurrences in the event viewer. I just dont know where to start with going through the logs.

    If the PSu dips in power it will shut the PC down.

    You can post your Hijack log and see if anything shows up

    In your Bios settings under "Power Management " you should find a setting for "auto restart on power loss" try disabling it. If the next time it shuts down it does not reboot you can be fairly sure it is a problem with the PSU. The PSU problem could be anywhere from the wall socket to a bad connector on the motherboard.

    I doubt an HJT log is going to show anything that could cause a System Shutdown without a BSOD occurring and it is permitted for anyone to request an HJT log in the general forums but you need special permissions (or above) to use the tool to make any changes.

    From that error it sounds more like a problem with a Windows Update that may be corrupted. Run through this guide and see if the problem continues.
