My motherboard is listed in my specs ( Asus Gryphon z87 ) with latest BIOS version 2103. I'm experiencing slow start up, laggy UEFI bios and unknown device problems too. Leaving the AUX power USB connector out seemed to fix the unknown device problem though. Noticed the keyboards unresponsive in bios, safe mode, starting up and shutting down. Lights stay on when the PC is off, but I fixed that by enabling ERP in bios. Would have been difficult if I didn't have UEFI bios, which has mouse support on account of the keyboard being unresponsive. Still took forever since it was slow and laggy, because of said keyboard. CUE software causes Dead Island to crash when starting the game and other compatibility issues with steam/games. My bios, chipset and all drivers are up to date.
