comp shuts down and restarts on its own. how can i get in it to pinpoint whats causing the error?

Yeah...sounds like a shutdown virus has been downloaded onto your PC. But before you go that route, have you checked if the fan is running well? At times the fan may not be working so well, which may cause your PC to overheat and shut down. But if you do have a virus, you should just google 'Shutdown virus' and see if there are any anti-virus files available. Good luck!

This could be a heat problem.  May one of the internal fans has stopped working, mainly the cpu fan.  If it was memory, you would get weird errors all the time.

check for viruses (specially when your system booting after connect to internet ) \ncheck power voltage \ncheck  cpu fan \nreinstall win xp \nif cpu fan is good

Your computer could have been heated too much.Try working on it after shutting down your pc for an hour or two.

try clicking altogether ctrl+alt+delete and click shut down. if it's still not working, you have to contact your pc manufacturer

Could be anything of a million and one reasons.\n\nTry taking the CD back out and see if it boots now.\n\nYou might have zapped the motherboard with static.\nYou might have unseated the RAM.\nYou might not have hooked the power supply back up.\nYou might have...\n\n///

All programs have to shut down before the computer can shut down.I sounds like you have alot of programs running in the background.You can go to the start menu and click on run,when the box comes  up that says open,Type msconfig and click ok.Now a box with several tabs will appear,click on the one that says start up.Now you can uncheck allexcept the ones that say windows system or kbd for the keyboard,now click apply then close and restart computer.When computer restarts,a box may appear that you can check to never show this again.If this does not help,then I would suggest that you have a memory or ram issue and the computer needs to be serviced by a professional.\n\nGood luck and I hope this helps you

When your comp. is starting up press F8, and then log on i safe mode, and the try to make one new one or configure a new one.

Go look at your power settings in the control panel and disable standby.\n\nWhat happens when you use the start button to shut down the computer?  SOmetiomes viruses and bad stuff will hang during shutdown. Make sure your antivirus software is up to date and running.

Well, in that moment of peril, try using <CTRL> <ALT> <DELETE> to open task manager and end any processes that are showing "Not Responding". However, this may not always work, though it might help.\n\nIn the future to prevent this from happening, try the following things.\n1. Make sure your PC is not overheating, with more heat, the performance falls. If it is overheating, buy a cooling dock fan for around $30 dollars.\n2. Make sure you are not running to many "stealth" programs in the background. These programs take up RAM and CPU. To fix this problem, go to Run and type in "Msconfig" and go to last tab called Startup. Now uncheck everything that you reconize from past program installations except for your firewall.\n3. Make sure you don't run too many programs at the same time. This would increase your RAM and CPU usage and cause your PC to freeze much easily.

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

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.

It could be many things.... start by disconnecting  your Hard Drive... if it still restarts and does not let you stay in the bios try a new Power Supply... if persist its most likely your motherboard... make sure to disconnect  everything else...

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.
