This MUST be a bad motherboard--right?

I have a system with the following:



Motherboard-----Albatron KX18D Pro II with a NVIDIA nForce2 Ultra400/MCP-T
chipset



Memory--------512 MB Corsair



CPU----- Athlon XP 2500+



Since this system was built, there's been a problem--Windows will not shut
down. When you tell Windows to shutdown, it restarts the computer.



Here are some things I've tried to fix this:



1. Updated the BIOS to the latest version.

2. Disconnected all peripherals except the main hard drive and floppy--still
restarts instead of shutting down

3. Unplugged all switches (power, reset) and LEDs (Power LED, HDD LED, etc)
from the motherboard and tried shutting down Windows. I was thinking a
faulty switch was shorting the startup pins, but it still restarted instead
of shutting down.

4. Replaced the boot drive (still nothing else connected but the floppy) and
put a fresh install of Windows XP on it with nothing else. Same problem.

5. Replaced the power supply with a much higher-wattage, high-quality one.
Still no fix.



At this point I'm thinking it has to be a defective motherboard--I can't see
how the RAM or CPU could possibly fail in such a way as to cause this. On
the other hand, there's a chance it could be the floppy, modem or video
card, those are the ONLY other things in the system I haven't replaced or
checked.



So, I am going to try disconnecting the floppy and modem and swapping out
the video card to see if that has any effect.



Is there anything else you can think of that might cause this problem?

It was the video card! I was using a Rage 128 PCI card. I swapped it for a
Matrox Millennium G400. I was able to shut down the system successfully! I
retried a number of times and every time I was able to shut down. Whee!

Have you checked for bios updates?
