I have the Asus Z87-M plus. I just had it up and running with the I7-4770k. Did a fresh install of Windows. Did all 218 Windows updates the bios came with the latest version 1107. Then I went and removed the I7-4770K and put in the I7 4790k I get no bios boot screen or keyboard. I can tell no keyboard because I have a light up steelseries. Not sure now what I can do about it. Any suggestions I appreciate it.
