So thank you all for the help.
Im a little bit frustrated because 1 of the boards is dead after 4 Days. (i waited 2 Month for it, because i ordered it in Canada). I try to contact the support that they send me a new.

I wish you great time.

Thanks again
Greetings

Hold on before throwing this board away;
I'm not fully convinced your board is dead. Some chips on it are still running. Did you try to power everything off, unplug the PSU, wait 10 seconds, replug everything, then power everything back on? Its called a power cycling and waiting for the charge to dissipate before repowering it on is important.
Every single time i've had a bunch of x's i always fixed it with this. A soft reboot does not work when there chips go derp like this.
And if this does not work, i would still suspect it would be more likely for the PSU to be bad than the board. Did you try with another, good PSU?
