My computer keeps turning back on after I turn it off..

The simplest thing you could do is to use a surge protector and shut the surge protector off.

Do you have a network connection?  If so, then Wake On LAN (WOL), could possibly be causing.

Are you sure it actually shut off, and didn't just restart?

Another thing that could possibly cause this is a similar feature of dial-up modems.  Some have a feature called Wake On Ring (WOR), that is designed to do the same thing if it gets a call.

Hi there,

    I have comcast highspeed internet and it does seem like it is just restarting instead of shutting off...I don't use a dial up modem...I've been getting alot of firewall alerts could someone have changed anything in configuration or anything?

Try this:

Windows XP restarts when you try to shut down your computer
http://support.microsoft.com/default.aspx?scid=kb;en-us;311806

1.      Right-click My Computer, and then click Properties.
2.      On the Advanced tab, click Settings under Startup and Recovery.
3.      Clear the Automatically restart check box under System failure, and then click OK. The error message should remain on the screen so that you can record the error information.

you can check the bios, for any restart otions, like wake on modem, wake on lan

...and it can be a motherboard or power supply problem too

I just put a new motherboard, power supply and CPU in and it has been working great.  I haven't changed any setting at all for it to have started to do this:(

Hey Crash,

   The thing about system failure scares me for my pc is new rebuilt, this clearing and everything won't hurt anything will it?  Can I get back to my desktop after I read the error message if there is one?

Thank you, (Waiting on needles and pins!)

All you're doing is changing a setting to prevent the computer from restarting when it crashes.  Instead of just restarting, it should show you an error on the screen.  Once you read the error, just turn the computer off, or press the reset button, and when you turn the computer back on, windows will start like it normally does.

You could also try this, check the event viewer for errors.  Go to start->run, type "eventvwr.msc" and say ok.  In the program that appears, click the "System" entry, and see if there is an error that occurred around the time you last tried to shut the computer down.

while i would advise this setting far everyone, it will do nothing for the restarting when you turned it off.

Hi There,

     Sorry I haven't commented in awhile have been on a trip :) Anyway Crash2100 I believe I did what you said and now whenever I rey to restart my computer I get a blue screen that says:

A problem has been detected and windows has been shut down tp prevent damage to your computer.

     Driver_IRQL_NOT_LESS_OR_EQUAL

If this is the first time you've seen this stop error screen restart your computer.  If this screen appears again follow these steps.

   Check to make sure any new hardware or softwarre is properly installed.  If this is a new installation ask your harware or software manufacturer for any windows updates you may need.

   If problems continue, disable or remove any newly installed hardware or software.  Disable BIOS memoryoptions such as caching or shadowing.

Technical info:

***STOP: 0x000000D1 (0x0000002B,0x00000002,0x00000000,0xF7B959B0)

*** kbdclass.sys-address F2B959B0 base at F7B95000, datestamp 41107b08

I don't remember installing any hardware or software.  I've seen this screen a couple of times when I restart.  Then I just push the warm boot button and windows starts normally.
     What is that about the BIOS memory options?  I do remember getting a couple of low memory warnings when I was building a website.  But just alotted more memory to the program I was using.  Any ideas?

Thank you,

Thank you very much Crash!! :)

     Yes I did install LogiTech keyboard program.  I will unistall it like you said and restart and see if it goes away,  I'll post back in a few.  I accepted your answer because I did install the LogoTech program, but now I will see If my computer will stay offLOL be right back:)
