[M2N-E] no screen, beep indicates "keyboard error"

Hi,

just bought some new hardware. after installing, there is no screen, just 1 long and 3 short beeps. This means "keyboard error" - i have no idea what this means.

any ideas? I need help!!!

thanx!
Felix

resolved

i removed some cables and fixed the vga-card again. now i get the starting screen now i must connect the hdds again hoping the vga-card was responsible
