Reboots on Power-down

[Guest]

Reboots instead on power-down.

When I go to shut down my PC, it goes through the motions of Saving Settings,
Shutting Down, Power Interupts (stutters) but then it reboots itself and
comes back to life as if I just booted normally.
The only way I can shut down is by holding in the power button to shut off
completely.

I have been dealing with this problem for allmost a year trying different
solutions that have been posted on the net. but so far nothing has worked.
Including the recommendations Posted on this site.
I have a high-end customed built pc, running XP pro. (2nd Edition) I have
all the latest drivers, updates installed. I had the system running under a
RAID 0, and recently re-formattted to a RAID 1 configuration to try to solve
this problem.

Right from the start, the system will reboot after a shutdown. Same as my
privious system install as a RAID 0 config.

Notes: I had a Antec 480 PSU installed, which is recommend by INTEL. My
lastest solution was replacing my Power Supply; Now I have a brand new Antec
550HE PSU installed. Did not solve the problem...reboots on power-down. I
have additional software installed now, including Bitdefender and Spyware
Doctor.

HARDWARE SETUP:
Thermaltake SHARK Case.
Intel P865PERL MB - BIOS Ver. p21 (lastest posted).
Intel P4 3.4GHz, HT. Bus speed 800MHz (system reconized as a dual processor).
1023 MB Mem.
Nvidia GeForce 6600GT Video Card (Latest Drivers installed)
Antec 550HE Power Supply.
Dual (x2) WD 250 Gig HDD.
Liteonit DVD-R Disk Drive. (Latest firmware installed).
Liteonit CD-R Disk Drive. (Latest firmware installed).
Std. Floppy Drive.
Intel 536EP Modem.
Microsoft Natural PS/2 Keyboard.
Microsoft USB IntelliMouse Explorer 4.0 (IntelliPoint).

No problem devises reported.

I am at my end...NEED HELP FROM SOMEONE WHO CAN HELP!

Your computer is most likely experiencing a system failure when shutting
down your computer. When this occurs your computer will reboot automatically
by default. I would suggest to disable this feature and see if a BSOD will
appear. If a BSOD does appear then write down the full STOP code and post
back.

To disable "Restart Automatically on a System Failure"

Control Panel > System Properties > Advance Tab > Startup and Recovery
Settings > Uncheck "Automatically restart".
