I would second the HW issue, if the machine is doing a full reset with 
no printout out of any type I would think PS, or some other serious HW 
issue, Linux generally does not crash without some error message.

How big of PS do you have?

I would try just dding the 4 disks at the same time and see if that 
also crashes.

And then if you can remove 2 disks from the machine and retest.
