On laptops the main reason for shutdown is overheating. First make sure the fan in back/bottom is working. If it is not, it will need to be taken to a shop for replacement. Check the back fan area for dirt buildup and clean it with a can of air. Also do not use the laptop on things that will block airflow such as in bed on blankets. A laptop cooling pad (has fans in it) helps also.

Right click on My Computer icon> properties>Click on Advance Tab>Down at the bottom find Start up and System Recovery> hit the settings> uncheck---Under System Failure----Automatically Restart..\nThat should take care of it temporarily.\nU might wanna rebuilt your PC from scratch...U might have some other serious issues which is causing it.\nGood Luck.

Go to Run and type shutdown -a . This will stop the shutdown sequence. However this is not the definite solution because it will pop up the next time you start your computer. It seems you have a Blaster worm that triggers this event. Update your PC to SP2 and the problem will be solved.

Because you are starting the process of shutting down your computer.  If you never started this process, your computer would never shut down.

First go to control panel > Power Options > Power Schemes > Settings for Home/Office Desk Schemes  and check whether you have activated any auto turn off for HDD or Monitior (say after 10 minutes). \n\nCheck whether you have activated any screen server which gives you a blank screen after certain amount of time.\n\nIf it is not this please make sure your data cable, mouse cable and keyboard cables are properly connected to your system. \n\nMake sure that no automatic shutdown tasks is created earlier.\n\nAlso run a virus scan so as to make sure that there is timer based viruses which activate them selves in a sp. time.

It may get overheated or some hardware is broken (it can be a HDD,RAM,Video card etc., I think the HDD has a problem). Try getting a hardware diagnostic tool.

Good information to help you resolve this would be:  new or used computer?  It could be shutting down for a multitude of reasons...  The first to come to mind is temperature.  Most motherboards shut down a few degrees before the processor's thermal breakdown point.  You may want to see that your heatsink is seated on the processor properly, and that any and all fans are functioning.\n\nAnother common culprit would be a virus.  Look for a free program that will let you do a boot time scan of your system.

shutdown the computer by holding in the power button about 30 seconds. there are gears that control the movement of the tray of the cd rom, if it doesnt work after restarting just buy a new one they are not economical to repair

Simple answer: Yes.\n\n\nA little more complex answer: If you screwed with your registry without knowing what you are doing, do yourself a favor and reinstall windows.  Registry can and will cause a computer to go into shutdown.  If you want to go through some ahssel, try to do a system restore to take you back to before this problem happened

If your power supply is faulty or your processor fan is broke your PC will shut down to cool down, but wouldn't necessarily start up again.\nIt sounds like a virus or worm infection.  I would try going into windows in safe mode (F8 function key normally) and see if the system continues to close down.\nIf it is stays on o.k. check you haven't installed a driver or software recently that may be conflicting with Windows.  If this happens you should be able to roll back the driver or system restore to a point where you know your PC was o.k. (In F8 this is the "Last known good configuration")\nIf it shuts down again it may be a virus, have a look on symantec's site for a hotfix for the latest virus/worm,if it is a virus you'll proably need to disable your system restore whilst trying to remove it.  Follow the instructions to remove it carefully so not to destroy your pc further!!

you may have anyone of the following problems: 1) Your computer may have a virus, use spybot (site bellow) to check. 2) Your computer may be overheating, try running your computer with the case open and see if it continues to restart. 3) if you have made any recent hardware changes, the new hardware may not be completely compatible, try removing it 4) your powersupply may be dying. Buy a power supply tester (a few bucks, see site below) and make sure that u are not overloading it.

you need to give more information such as...\n\n1. did you get an error when it closed?\n2. what happens just before the error occurs?\n3. does windows freeze?

Shutting down your PC should ALWAYS be done by using the "shutdown button". Windows will unload certain components from the memory, save it's present settings and flush the virtual memory when doing so. \nAs stated in the former comment, shutting it down by the power switch (aka hardware reset/shutdown in contrast to software reset/shutdown) will result in the loss of ANY non saved information on your pc and mey provoke STRANGE results on boot-up (desktop settings lost, driver missing etc...). It should ONLY me a last step measure when the pc hangs (does not respond).

might be that your cpu overheated....\n\ncould also be software issue..ie..spyware.\n\ncan also be your HD encountered bad error\n\n\nwhat am i trying to say?  that symptom alone is too generic.. could be a lot of causes

Is the computer on standby? If it is then you should shutdown the computer instead. \n\nRun an antivirus program on your computer to see if a virus may be the cause as well. Also check to see if you have had any recent errors, like driver conflicts or "the blue screen of death". That could also be a cause.
