I can tell you right now it is the MSI board. Their boards are complete ****. Take it from a former MSI owner get something different and the headache goes away. If you want to satisfy your curiosity run the Linux Firmware tests and watch what happens with MSI BIOS. I paid $35 for a brand new board from MSI and well you know the saying - you gets what you pay for. Had I spent just $30 more it would have saved me a pile of headache. From what I can see they have hacked a BIOS and it doesnt work.
