i think i have a cpu fail with my other motherboard (msi z77a-gd55)
and i try everything i could
i plugged my phone on the usb front panel to charged my phone
and i have a notice than i unplugged an audio device
after a couple a minute the monitor goes black?v
i make a reset but nothing and the computer won't bootv
thing's i try:clear cmos
remove the battery fo the nigth, unpluged compu
change the ram 1 or 2
try another gpu and monitor
try to boot without hard disk
nothing appen

so i try my brand new motherboard and the computer wont boot
and i haved this red led boot device on the board

do you think it could come from a damage cpu

Make sure the videocard is installed in the top PCIe slot, then reset CMOS.

I have a crossfire
But i really think the cpu's dead
I think my last motherboard kill it
I m gonna wait after intel ram

Then remove the 2nd videocard w/ the remaining one in the top slot.

I try all i can try
Ram, gpu , monitor, boot without hard disk
Nothing's work, the monitor stay with a black screen
I don't see anything.
The fan, the mobo , the gpu work
Has i tell i think the cpu is *-( dead

Check the CPU socket.

The board are brand new

I'm not sure why you decided to create a new thread instead of just BUMPing your old one from last month, so I just merged the two. Is the 4 or 8-pin power plug from the PSU connected to the EATX12V connector on the board? And what code is showing on the readout at the lower RH corner of the board?

Why check the cpu socket
It look fine , nothing are damage
The board are brand new

The reason RJ suggested checking the socket is because sometimes even brand new boards come w/ bent pins in the socket, which can cause the same sort of issue you're seeing.
