Power supply would be my only guess to cause system wide failures with 2 separate motherboards, both of which would be unlikely to be bad in the same way. I have used a number of the AMD build sata2/sata3 MB controllers and never had them act up even when using all of the build-ins at the same time heavily. Possibly the sata3 uses a bit less power and that lowers things just enough that it does not happen, or possibly the sata3 chipset will survive with a lower voltage than the sata2 chipset. Power problems do weird things...whatever component is the most picky on its voltage will be what flakes out, and it can be just about anything. If both of the MB's were a similar AMD chipset then likely the weak point is the same.
