[PLUG] Hardware driving me nuts!

Abit NF-M2S with onboard Gigabit and nVidia GeForce 6100 and 405 chipset
Two 320 GB SATA II drives
Two DVD+-RW Dual layer
AMD-2 4600 64-bit
Two 1-GB Corsair RAM
Raidmax case, replaced PS with Antec 500 w

Any time I have extensive disk activity I get a sudden power off, like
pulling the power plug out of the back. I have run the Western Digital
Lifesaver Diagnostic Utility on the Ultimate Boot CD and it ran all the
way through (70+ minutes) with the hard drive light on constantly the
whole time. No errors. But formatting a partition will power off the
computer after a few minutes. So will adding a device with mdadm.

I have replaced the the power supply and I have swapped the motherboard
for a new one, but the problem persists.

In the BIOS there is an option to shutdown on certain errors. I set it
to "no errors." I think that applies to booting only, but I'm grasping
at straws here. 

Does anyone know if there is a list somewhere of hardware faults that
can cause a sudden power off? If this was your box, what would you
suspect next?
