A have Asus z87-Pro motherboard, which fell into strange cycle: during startup it produces following message: "CPU fan error!" and goes straight to BIOS. Needless to say, that cpu fan works fine.and it's recognized by BIOS and there current fan speed displayed properly. Switching to the optional connector, turning off monitoring cpu fan produce same result.

My machine stuck in that visions cycle and unable to lead her out of it.

UPDATE:
Ok, I've been able to clear CPU fan error, but now I am getting "AE - Legacy Boot Event" error code. Have no clue what that means. And, I suspect, that's why machine is going to BIOS directly instead of booting. It's kinda funny: machine IS a legacy one.:))) Saga continues...
