Same problem here...I bought K70 RGB a week ago. For 4 days the keyboard was working great, no slower boot. Then there was "keyboard malfunction" error in CUE and the trouble started. Sometimes the PC was stuck at the ASUS logo, sometimes it wasn't. Yesterday I updated BIOS. Still the same. Tried to enable Full Initialization, enable Legacy support. Connected the keyboard to one USB2, two USB2, one USB3, even two USB3. Sometimes the PC starts normal, sometimes it says that "no keyboard found". My MB is Asus H97-Pro. Everything up-to-date.
