your mb has a back up bios..if you clear the cmos it may boot to the back up bios.
sounds like you turned the pc off too soon. http://forum-en.msi.com/index.php?topic=119375.0
Thanks for the reply. I tested the psu with a paper clip test just to make sure it wasn't the psu. I tried clearing the CMOS and removing the CMOS battery. The problem is that nothing is booting. There isn't even any power going to the components attached to the motherboard, so it has no chance to switch to the back up BIOS.
I think I might have to RMA the board. It is still under the warranty. BIOS update failure aren't covered are they?
