Shutdown problems can certainly be the work of spyware and the like, but it's also just as likely the result of (non-malicious) software conflicts or corruption. \n\nLet's see if the system is leaving any "suicide notes": Open the Event Viewer utility in your Administrative Tools control panel and look through the system and application logs for any errors, warnings, or other messages which might point to the source of the problem.

probably you are not shutting down the system properly. Make you do it correctly.

I heard that happening with some anti virus software.\nTry shutting down after deactivating the software.\n\nIf that doesnt help try finding out if its a hardware problem.\nGet a program called "end it all" which will close down all running applications and your computer should shut down, if it doesnt then its a hardware thing.

Goto your CONTROL PANEL and select POWER OPTIONS.  Make sure it is set at a level you want, I assume it says to turn off hard disk after 20 mins...Just change that to NEVER.

some application that is running and then refuses to close down on its own when you shut your computer shuts down, if you want it to stop happening, run msconfig.exe and then uncheck it in the start up menu, if it doesnt start up it cant be forced to close down, if its some crap you need for your comp to run well then , kill yourself and blow up your computer at the same time cuz i dunno

Buggy RAM?  Was it all of a sudden?  Try running spyware tests.  Could be hidden programs task manager doesn't see.  You say you "sometimes" have the problem.  Any triggers that might set it off consistently?\n\nHave you considered reinstalling windows?  Might help.  Good luck.\n\n--An addition to Jerry's suggestion.  If the fan is kaput, the whole system will slow down.  I had a fan that was stuck from time to time.  Once I figured it out, my sys was back to normal.  Thank goodness I figured it out before the CPU fried.

could be a hardware or heat related condition. if the fan for the cpu stops working, the cpu will get too hot and the computer will shut it's self down.

the computer turns off, because you might be eitehr using MS windows 2000 or MS Windows XP service pack 1 which had lot of errors. USe MS_windows XP Service PAck 2 for the computer to run better. Hope it solves your problem, enjoy.

On a laptop, it shouldn't affect the computer, provided your battery is in good working order.  If your laptop's power supply failed, your batteries should kick in until AC power is restored.  If you think it's your power supply, try to get another one to see if it happens with that one.  If that's not the case, then it may be an internal issue (overheating, for example).\n\nOn a desktop, though, the power supply might be a cause, but then again, viruses, a bad motherboard, or overheating could also be causing your computer to reboot spontaneously.  You'd have to take more notes when it happens - does it happen when you do a particular thing (maybe a virus) or after a certain period of time (maybe a virus or a heating issue), or is it completely random (power supply may be working intermittently)?  And then, after your computer shuts down, does it come back up immediately or does it take a few minutes to start again (maybe a heating issue)?  I would check for viruses first before getting into the case.  If I went into the case, get some compressed air and blow out all the dust, and then see if all your fans are working properly.  And if that doesn't help, try another power supply if you can.

you will need to check your settings, some times the computer is set up to shut down if it encounters a fatal error or " BLUE SCREEN OF DEATH"  do this  ...right click on START, PLACE YOU MOUSE POINTER ON ADMINISTRATIVE TOOLS, THEN  RIGHT-CLICK ON EVENT VIEWER, THEN RIGHT -CLICK ON  APPLICATION OR SYSTEM, it will have a warning sign that says something about whats causing you shutdown, you might have to research the answer through  THE HELP SYSTEM IN WINDOWS or on microsoft .com or you  right-click on START, put your mouse pointer on CONTROL PANEL, then right-click on  SYSTEM , then right-click on ADVANCED, go down to START-UP AND RECOVERY and check your settings, where it says SYSTEM FAILURE, make sure AUTOMATIC RESTART is unchecked. and that WRITE A EVENT TO THE SYSTEM LOG and SEND A ADMINISTRATIVE ALERT is checked. then try again, a error should show up explaining the problem so you can use the WINDOWS TROUBLE SHOOTER. to solve this problem.

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.

Your PC is shutting off, because you have two or more Anti-virus programs installed and they are not compatible.\nYou need \n1 Ad-Aware\n2Anti-virus\nand a good firewall

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.

It is possibly overheating. Check the fan. Check power supply, it could be going out. If not:\nYou probably need to reorder your BIOS by hitting del on startup. If you dont know how to do this please dont try, get help first.\nHere is a search of this problem, choose one of these forums that seems most similar to your system and ask them. They should be able to help. Its hard to troubleshoot a problem on Yahoo Answers as we cannot easily have continuous dialogue.\n\nGood Luck!\nhttp://www.google.com/search?hl=en&q=computer+restarting+over+and+over

This could be a cooling issue, check your fans and dust out your system. I saw one system the other day that did this because of the massive amount of dust, even though the fans were still turning. \nAlso try starting the computer in safe mode and see if it works then or locks up without restarting. A bad XP install will cause this sort of action. Sometimes there is a bios option that tells the system to restart on error, you can turn this off to help diagnose the problem.

Try removing programs that you don't use. There may be something shutting down in the background that you don't know is running. Also get a good spy-ware removal software such as Spyware Doctor. There could be hundreds of little spy programs running without your knowledge. When Windows shuts down it must first shut down all of the programs that you have running.
