Windows Vista Computer Reboots Randomly

    Question

  • Hello,

    My 4 year old computer running Vista Home Premium recently started rebooting itself for no apparent reason. The screen will sort of disolve into colored pixels and then disappear and go black.  Sometimes it will just stay that way but the computer will still be running.  Other times it will reboot itself and come back to the screen where you can choose to start normally or other starting formats.  I choose start normally and it comes back to the sign on screen and will sometimes run as normal like nothing ever happened.  There are times when it will go back into reboot mode after the desktop appears and whatever programs in the background are done loading.

    Not sure if it is hardware or not. But I ran a diagnostic test with the Vista programs and it says there is a service that is stopping abnormally. What are my options here?

  • Hi,

     

    What is the make and model of your computer?

     

    From the symptom, it is likely has something to do with your graphic card. Please tell us the model.  We can find and install the latest driver to check the result.

     

    As you mentioned the disgonstic test and a service, could you clarify what are they?

     

    At this point, certain things you can try are to find out the root cause of the problem are given below.

     

    1.    Have a look whether you can reproduce the problem in safe mode.

     

    Start your computer in safe mode

    If behavior doesn’t persist in safe mode, it indicates that a third party program or service is preventing you from performing the action as supposed to.

     

    To validate or determine which service/startup item could be causing this, restart the computer and boot to desktop normally. Once done, perform clean boot.

     

    2.    Clean Boot prevents software conflicts by preventing the startup items and non Microsoft services from loading. This way you can safely follow the process of elimination to check which application is causing this behavior.

    Note: Ensure that you put your computer back to normal startup mode after completing the troubleshooting steps. Steps are available in the article given above.
