WinXP Pro won't shut down

[crazyray]

New install of XP with service pack 1a added. PC has ATI Rage Pro card , a Realtek NIC and a firewire card. All drivers were installed by XP. There is one hard drive and one DVD drive but no floppy. The system uses a board with an Intel 845 chip, a P4 2 ghz CPU and 512 MB's of DDR 266 RAM.

Whenever I attempt to shut the PC off, I get the splash screen indicating that it is shutting down and everything appears to be shutting down normally, but it reboots spontaneously. I have NO software installed (no ROXIO). I have unchecked the "automatically restart" box in the advanced properties tab in My Computer.

I would appreciate any help or links available. (Merry Christmas)

Try shutting down all running programs( applications ) and see if that does it. Then check the processes to see if you can eliminate unneed processes.

talks about roxio issue, but also other ussues...the second fix is the one that might apply to you.

-------------------------------

Windows XP may encounter a problem during startup that results in a STOP error message. Depending on the system configuration, the error message on a blue screen may not be displayed long enough to record the error information. To gather important information about the STOP error message and to verify the cause:

Right-click My Computer, and then click Properties. On the Advanced tab, click Settings under Startup and Recovery.
Click to clear the Automatically restart check box under System failure, and then click OK. The error message on a blue screen should remain on the screen so you can record the error information.

Instantly Reboot Upon a System Fault

Start/Run/Regedit. Navigate to...
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\CrashControl

In the right pane choose AutoReboot/Right Click/Modify. Change value to 0 to disable and 1 to enable.

------------------------------------------------------

possibly that reg entry and last sentance might help....see if you have that key and if its set to 1..try setting it to 0

But they did not solve the problem. After extensive googling, I found someone who blamed this problem on their firewire card! Sure enough, I disabled the entry in the BIOS "Wake up by PCI/WOL" and the problem went away...

This system is using an Antech "home theater" case. It is oddly shaped and uses low profile ("half-height") cards. The firewire and video cards were bought off eBay specifically because they would fit. I was able to, er, "modify" a NIC card I had to fit. I don't know if it is related, but the firewire card came from a Gateway box...

Onward and upward!

I had the exact same problem and it drove me crazy. I found out finally that it was the drivers for my Microsoft Keyboard believe it or not. I had to go to the web site and download and install the current drivers for the Microsoft Intellitype Pro Keyboard. It worked, no problem since.
