windows 7 (x64) restarts randomly RRS feed

  • Question

  • When I'm using my laptop (Sony Vaio) more and more often, the screen goes black all of a sudden and the system re-starts a few seconds later.  How do I fix this problem? 

    Thank you in advance for any answers.

    This troubleshooter should help resolve this issue :

    Could be heat related - try using a small fan to blow into the air intakes to see if that helps.
    Does it just act like it loses power or does it shutdown in a normal manner?

    Remove ALL power and reseat all card, memory, and cables (both ends) - actually remove
    and replace - do not just snug. Remove the dust bunnies and clean the vents. Check that the
    fans work (before and after opening the case). If a laptop about all you can do is reseat the
    memory and clean the vents (still can try adding a small fan as a test).

    Vista and Windows 7 love updated drivers so here is how to update the major ones.

    This is my generic how to for proper driver updates :

    This utility makes it easy to see which versions are loaded :

    DriverView - Free - utility displays the list of all device drivers currently loaded on your system.
    For each driver in the list, additional useful information is displayed: load address of the driver,
    description, version, product name, company that created the driver, and more.
    http://www.nirsoft.net/utils/driverview.html

    For Drivers check System Maker as fallbacks and Device Maker's which are the most current.
    Control Panel - Device Manager - Display Adapter - write down the make and complete model
    of your video adapter - double click - Driver's tab - write down the version info. Now click UPdate
    Driver (this may not do anything as MS is far behind certifying drivers) - then Right Click -
    Uninstall - REBOOT this will refresh the driver stack.

    Repeat that for Network - Network Card (NIC), Wifi, Sound, Mouse and Keyboard if 3rd party
    with their own software and drivers and any other major device drivers you have.

    Now go to System Maker's site (Dell, HP, Toshiba as examples) (as rollback) and then Device
    Maker's site (Realtek, Intel, Nvidia, ATI as examples) and get their latest versions. (Look for
    BIOS, Chipset and software updates at System Maker's site while there.)

    Download - SAVE - go to where you put them - Right Click - RUN AD ADMIN - REBOOT after
    each installation.

    Always check in Device Manager - Drivers tab to be sure the version you are installing actually
    shows up. This is because some drivers rollback before the latest is installed (sound drivers
    particularly do this) so install a driver - reboot - check to be sure it is installed and repeat as
    needed.

    Repeat at Device Makers - BTW at Device Makers DO NOT RUN THEIR SCANNER - check
    manually by model.

    Manually look at manufacturer's sites for drivers - and Device Maker's sites.

    How to Install a Device Driver in Vista Device Manager
    http://www.vistax64.com/tutorials/193584-device-manager-install-driver.html

    If you update drivers manually then it is a good idea to disable Driver Installations in Windows
    Updates, this leaves Windows Updates ON however it will not install drivers which will usually be
    older and cause issues. If Updates suggests a new driver then HIDE it (Right Click on it) and then
    go look for new ones manually if you wish.

    programs, update major drivers and BIOS, and also troubleshoot with the cleanboot method
    first.

  • Hi,

    Use the above troubleshooter and these might help gather useful information.

    If there are any BlueScreens or minidump files created.

    Check this thread for information using BlueScreenView, MyEventViewer and other methods
    to troubleshoot BlueScreens - top 3 replies (+1 other).

    http://social.answers.microsoft.com/Forums/en-US/w7repair/thread/c675b7b8-795f-474d-a1c4-6b77b3fcd990

    We can analyze the minidumps if you make them available from the SkyDrive or other file
    sharing sites.

    Zip or upload the contents of C:\Windows\minidump

    Use SkyDrive to upload collected files
    http://social.technet.microsoft.com/Forums/en-US/w7itproui/thread/4fc10639-02db-4665-993a-08d865088d65

    -------------------------------------------------------------------------

    Also do this so you can see the likely bluescreens (if any).

    Windows Vista automatically restarts if your PC encounters an error that causes it to crash.
    (also Windows 7)
    http://www.winvistatips.com/disable-automatic-restart-t84.html

    ===========================================================

    Check with these utilities to see if any information can be gathered :

    This is an excellent tool for posting Blue Screen Error Information

    BlueScreenView - Free - scans all your minidump files created during 'blue screen of death'
    crashes, and displays the information about all crashes in one table.
    http://www.nirsoft.net/utils/blue_screen_view.html

    -------------

    MyEventViewer can be checked at the time of the BlueScreen (BSOD) to within a second or
    so of the time of the BSOD to provide more information as to possible cause - see TIP.

    MyEventViewer - Free - a simple alternative to the standard event viewer of Windows.
    TIP - Options - Advanced Filter allows you to see a time frame instead of the whole file -
    set it to a bit before and after the time of the BSOD. This also can help for events
    other than BlueScreens so be sure to check immediately after one of those
    reboots.
    http://www.nirsoft.net/utils/my_event_viewer.html

    ------------

    AppCrashView - Free - a small utility for Windows Vista and Windows 7 that displays the
    details of all application crashes occurred in your system. The crashes information is extracted
    from the .wer files created by the Windows Error Reporting (WER) component of the operating
    system every time that a crash is occurred. AppCrashView also allows you to easily save the
    crashes list to text/csv/html/xml file. This also can help for your issue.
    http://www.nirsoft.net/utils/app_crash_view.html

    Hope this helps.
