Why can't you rma it? Msi will accept an rma as long as there is no physical damage to the board (shorts, burn marks, modifications, etc.) I would go ahead and request one. To possibly get your board going, try using the cmos jumper to reset the bios. Move the jumper over one position keeping two of the three pins covered, then return to the original position. Do this with the power supply unplugged.
I'll go try that.. and let you know if it worked or not. And I didn't know that about the rma from them
It didn't work.. how long are you supposed to keep the pin in the second position?
