Just this morning I updated the bios to the latest one which is 7C80v18. Update went fine and when the pc rebooted, no display was shown and the cpu debug was lit and stayed on. After 3 hours I power cycled the pc and the had same result of the CPU Debug led being lit.
I have tried everything from removing/replacing the cpu, putting one stick of ram in the first or second slot, cmos reset (battery removal and replacement), removing all usb devices and gpu etc, still no luck.
Wondering if anyone else had this issue and what they did or if they had to RMA the board.
 
The same happened to me. It's not recognizing any of my peripherals and says the CPU has a failure. I have done everything as well and this is my last resort.... following and glad that im not the only one.

Usually this is my luck. Im also glad im not the only one. I just fear with no bios flashback on this board we are screwed if it cannot be something simple.
 
I couldn't find a fix for this. Tried everything yesterday. I need the system to work as it's my secondary work pc and gaming pc so I am going to most likely get another board and sell mine for parts. Hopefully someone can find a fix though.
 
I am a little disappointed in MSI right now. This is evidently an issue that people are having and they have, as of yet, given any response. This is beginning to make me second guessing my purchase.
 
Ok that is very unusual, they should've caught that during in-house testing before this BIOS was released to the public, if the issue so common. We got four different people here with the same board the and same problem, apparently. You should all log into the MSI member center, https://account.msi.com/ and report the problem. If four different people do that with a new BIOS all of a sudden, that should ring some alarm bells at MSI.

Will do . Had to buy an Asus Tuf board because all my troubleshooting went nowhere. Hoping MSI helps us out here with this as I smell as lawsuit coming for releasing a bios update that bricked motherboards that wasn't even a beta bios. Then there is no way to revert it or bios flashback on this board.

Already reported, going through the usual over and back with technician to confirm the issue. Going the same route as @datz.bunz and buying new board to tide me over til I get RMA return.

Reported it two days ago, but I haven't gotten any reply yet.
 
out of interest, anyone know what this does:

hoping support will come back to me and say there is an undocumented dual bios on the board :-)
