you know that voltage regulator thingies on your board? You know, that the bios does more than setting ram speeds - like setting the signal strenght on a couple of 'busses', like agp, or sata or pcie?
So a different bios might drive the pcie-bus with a stronger signal (more volts) which might be able to solve line noise&low voltage related problems.
