Unless you have been messing around with the system files or anything like that, than you probably have a virus. You need some good antivirus software installed and you should be behind a firewall. I use norton antivirus and Zonealarm Pro for my firewall, both have never failed me. Also you should stay away from any bad websites, like porn, anything to do with getting serial numbers and cracks, and anything else shady looking. You will get infected in no time flat. For now I would suggest you go to http://www.pandasoftware.com/products/activescan?NRMODE=Published&NRORIGINALURL=%2factivescan&NRNODEGUID=%7b3B202047-35D4-4DA2-B310-B1DBEC2971F2%7d&NRCACHEHINT=Guest and do an online virus scan right away before any more damage is done. Good 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.

1.) did you reboot the computer?\n2.) uninstall and install the Software?\n3.) stop stuff that is comming up on start up that you do not need!\n4.) it may just be time for you to reload everthing.

You have a virus. It won't shut down because the virus prohibits the computer from being turned off. This is to corrupt data and transmit if you have any Internet connection. Please check your computer for a potential virus. It's best to be safe than sorry.

Try starting it in safe mode (hit F8 while it is booting).  If it starts in safe mode and does not freeze then you obviously have a software problem.  Try using mscong to stop a few things in your start-up, beginning with your anti-virus program.  Keep track of what you turned off and back on and you will eventually hit the problem program.

Sounds like you have a bug. Take your computer into a repairman (or repairwoman).

Could be that your CPU fan is not running or dirty, the CPU is over heating and causing the PC to reboot.\n\nYour Hard Drive is about too die.\n\nA sticking key on your keyboard.\n\nBad BIOS .\n\nGood luck, caned air and a vac helps your PC stay cool.\n\nOther then that I would run disk check and de frag.\n\nAlso in my old place this guys CB radio used to make my PC reboot.\n\nOk how abou a grounded out USB, that will do it, unplug any USB things you have and see it it does it.\n\nAlso make sure the USB female slots are not grounded to the case.\n\nA screw can be wedged between the Mother Board and the case.

Press the power button for 10 seconds.  That will shut it down hard.   Then restart.   If you have the same problem, trying starting it in safe mode.

If Windows XP suddenly starts without warning, or restarts when you try to shut it down, it may be because your operating system is set to automatically restart when certain system errors occur. This feature of the Windows XP operating system can be disabled. Use the information below to disable the Automatically Restart option. \n\nResolve this issue by turning of the Automatically Restart option: \n\n1. Click Start, right-click My Computer and click Properties. \n2. Click the Advanced tab and select Settings in the Startup & Recovery section. \n3. Remove the check mark next to Automatically Restart under System Failure. \n4. Click OK to close the Startup and Recovery window and click OK to close the System Properties window. \n5. Restart the PC.\n\nThe PC will no longer restart automatically when a problem occurs. Instead a blue screen appears with more useful information. You can now search for a resolution using the text from the error.\n\nAfter you perform the above steps, check if the issue persists in "safe mode with Networking", scan for virus, get the BIOS update from the manufacturer.

OK you do not provide a lot of information as to your system.\n\nFirst boot into safe mode by pressing the F8 key once the computer starts to boot. Choose command prompt only and see if it still shuts down.  If it does not that is good.  if it still shuts down, open the case and remove any expansion cards you may have installed except for the video card iof you have one.  Remove and put back in the memeory.  Look for lots of dust in the system also if there is a lot of dust then take the system outside and blow all the dust out with either canned air or an air compessor use care  not to blow too hard.  Pay attention to the poser supply.  After cleaning the computer out and reseating/removing all of the cards and memory restart the computer in safe mode and see if it stays on.  If so it is probably fixed.\n\nIf it still shuts down it is probably a bad power supply or the processor is overheating.  if you feel confident you can reseat the processor and replace the power supply.  If not ask the local computer nerd at work or a friend for help.\n\n\nIf the computer still shuts down it is probably something major.\n\n\nTo make sure a virus is not the problem just disconnect the power cable to the hard drive and boot the system.  if it will stay on but shuts down with the drive booting then there is a good chance you have a virus.  Do you have antivirus software installed and up to date?\n\nhave you tried system restore going back a week or so?\n\nRemoving a virus is a whole different question

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

#1 - you need to be more specific about what you are trying to do and when, since your problem could come from a hundred different causes, BUT\n#2 - try turning your computer OFF, leave it off for 20 seconds, and turn it back on. Is the problem still there?

I don't know what causes it, but it has happened to me.  I just reboot my computer and it fixes itself.

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!!

If your laptop repeatedly restarts even though you are trying to shut it down, the best thing is that you repair the Operating System. But that is what you don't want to do. You want an alternate way out. \n\nThe best alternative is to put the Laptop into hibernation. There are two ways to do so. \n\nFirst, it is very simple. Just close the screen of the Laptop (I mean to say that just pack it off). The next time when you will open it up, it will have the same program running. No data will be lost and no unusuall behaviour will be shown by the machine. \n\nSecond, you can set up the hibernation option (this is for the Windows users only). Go to Control Panel> Power option. There you will find the hibernation tab. You can then enable the hibernation in your Laptop. After this go to Start> Turn off Computer. Then press "Shift" button. The "Stand By" option will change into the "Hibernate" option. Keep pressing the "Shift" button and click the "Hibernate" button and the Operating System will go into Hibernation. \n\nJust pack it off and go to sleep!
