If it's not power then I'm still with Alan re the cables. Maybe you have very long cables?
I used Alan's nForce4 pata driver for a year or so and didn't have any problems. OTOH maybe at this stage it's worth checking whether amd74xx (old IDE) breaks in similar ways?
Also, I assume you've memtest86'ed the machine?
