Why does my computer shut down randomly at least once a day?

null May 27, 2011

I use Internet Explorer 8 and Windows Vista. At least once a day and sometimes as much as 3-4 times a day my PC shuts down by itself. What can I do to fix? Thank you

    There are several possible causes for your PC slowdown--and as many solutions. There's a article (http://www.articlesbase.com/software-articles/free-tips-for-computer-maintenance-4849091.html) that talk about repairing and maintaining your computer with built-in utilities and free software. I hope it will help for you to speed up your computer.

    Don't know why nobody asked this yet but...
    Is this happening while you are actively using the computer or after you have been away from it for some time?
    If it is happening while you are using it, open up the Event Viewer and check the System log for any warning or error messages.  They may lead you to the culprit.  Checking for heat related issues may produce results, but they can be difficult to track down depending upon what sensors are available on your system.
    If it happening while you are away from the system, it is probably just your power settings dropping it into a low-power mode (suspend/hibernate).  This can be remedied by changing your power settings in the Control Panel.

    Hello, first thing I would do would be to open the case and make sure that your cooler fan and also the power supply fan are free of dust/dust bunnies.  You can get a can of compressed air and clean it.  Also make sure that your cooler fan is working.  Sometimes due to wear and/or mechanical malfunction the cooler dies.  Make sure that your cooler fan is working.

    It would also be very important for you to remove the cooler fan for the cpu and make sure to clean old thermal paste.  Get a good quality thermal paste that you can get at the computer store and apply new paste.  If you do this, make sure that when you install the cooler back, it is tight and set the right way.

    It would also be a good idea to install some extra fan/fans on your case to help with the cooling of your computer.  Air flow in the case is very important to keep the case cool.  By default computers have certain default settings that when reached, tell the computer to shut down/restart to protect itself.  Usually if the cpu/motherboard reached a temperature of 70 degrees it shutdowns by default.

    You could also disable the automatic restart.  When you disable the automatic restart, it will give you a blue screen that contains an error.  Once you have the error you can research it and/or post it here so that somebody can help you.

    To disable automatic restart on vista do the following:

    -- click on windows key + Pause/Break key
    -- on left hand box find and select advanced system settings
    -- click on start up and Recovery
    -- on the bottom of box, make sure to uncheck automatic restart
    -- make sure that the option to write event to log file is marked
    -- click on ok

    When the computer shutdown/restart next time, it will give you a blue screen.  Make sure to write the error code you get.  Every time the computer restarts/shutdown because of an error, it will write a file to the minidump folder.  You can get software like http://www.resplendence.com/whocrashed that can tell you more about the errors found on the minidump folder:

    Also you can check the log file for more information about what is causing the problem.  To see and check event viewer do the following:

    -- click on start
    -- type event viewer on search box
    -- click on event viewer
    -- expand the windows logs option
    -- select the system option
    -- check the events that give you warnings or errors

    Turn off power management, of all types, in Windows see if its the guilty

    Open Event Viewer and look for messages/reasons

    You should try to run some system monitoring software like CPU-Z: http://www.cpuid.com/

    It could be that your computer is overheating and it shuts off because of that. How along ago was it since you did maintenance to the hardware (remove the dust, cleaned it, etc.) A system Monitoring software can log everything in your PC so when it shuts down after reboot you can check the log and find about what happened. Like a planes' blackbox.

    Can you listen the cooling fans being activated when you use the computer?
