When I shutdown XP-pro the computer just reboots.

A month ago it started. Hit or miss. Sometimes the computer shutdown, sometimes it rebooted on sutdow. Now it just reboots when I try to shut it down. WHen it reboots it loses the network connection. Going into "standby" first doesn't help.

Temps are good.
Viruscan says no viruses.
No new hardware. Just a couple new programs, VOIPbuster and filezilla (FTP client).

I'm pulling my hair out. Why does this thing reboot when it should shutdown?

If you boot in safe mode, does it still not shut down properly?

How old is the MB? Look for bulging caps. I have seen that cause that type of problem

Take Panther505's post seriously. Older failing hardware leads to wacky problems.

Your motherboard isn't Abit by chance?
 
I deleted filezilla and voipbuster. Still reboots. Reboots from Safe mode.
I can't even shut it down using the on-off button. It just reboots after pressing that. I'll be looking at the capacitors next.

The MOBO is an ASUS A7n8x.
 
RE:"Do you happen to have the reboot on critical failure -- or whatever that feature is titled -- on"

I turned that "automatic restart" option off and no effect.

I'm wondering if this could be power supply related?
 
I have tha same issue, I changed video card, memory chip, NIC card, HDD, and still rebooted quite often. So finally I decided to take a closer look at the mobo, and bingo, bulging capacitors, so I sent the mobo back to the factory, after paying $30.00 because the warranty expired. When I got the mobo back, no more issues.

I had te same issue, it used to restart everything in my PC , took a look at the Nexuz fan controller and some wires were exposed and causing a couple of fans to function abnormally, so I rewired everything back and never had anymore issues.
 
have you check with the casing wire (hdd, power and so on) which connect to the motherboard is connected properly or plug it on the proper place??
 
Opened the case, blew it out real good.
Don't see any leaking or buldging capacitors.

Still can't turn it off, it reboots...
Unlike a restart, something clicks inside once when it turns back on. Almost like it's restarting rather than rebooting.
 
Check your network cable.

Go into BIOS and turn off Wake On Lan and Wake on Ring. It may think it is getting the wake command.
 
RE:"Go into BIOS and turn off Wake On Lan and Wake on Ring. It may think it is getting the wake command."

I can't seem to find it in the BIOS. Any ideas where is is?

mobo is Asus. A7n8X

Power Management. Also, check for new BIOS. This was a symptom of bad ACPI implementations, but you have been working, so I would put that lower on the list, but still possible.
 
I checked and "power on lan" was already disabled... Still reboots. I dunno what to do about ACPI, it's activated in the bios. The computer has worked flawlessly for 3 years.

Could this be a PS-powerswitch problem?
 
Find the shutdown.exe, not exactly sure where it is, a malware program can rewrite it with a -? switch and cause the computer to reboot no matter what. Try creating a shortcut on your desktop for shutdown, with no optional parameters and see what happens, if this works, then reconfigure your computer to use this shutdown method upon request... just a shot in the dark...
 
On my computer the shutdown.exe files show modified in August 2004. Much earlier than when this all started. Other than that I dunno how to tell if they have been hijacked.

That isn't the first place I'd look, but it would be easy for you to test - do a parallel install of Windows XP (say, to c:\winxp, rather than c:\windows) and test if you can shut down that install properly.

However, since safe mode has the same shutdown problem, I'd guess it's a problem with your hardware. That said, a parallel install would be an easy test....
 
If the OS can't catch the problem and throw up an exception (read: if the OS doesn't show a bluescreen or do a reboot which masks a reboot) then that means the hardware is failing, not notifying the OS, and taking down the machine.

Things to check: No minidump in c:\windows\minidump (check the dates...), no dumpfile in c:\windows\memory.dmp, and no memory.dmp / minidump entries in the System portion of the Event Log.
