Hi guys -



Just completed my build and everything seems to be working fine in terms of fans turning, lights, PC booting, etc.



I am having difficulties getting into the BIOS - mainly due to the keyboard at times not being recognised. I say 'at times' because it takes waiting 5-10 minutes on the "ASUS / Press F2 or DEL for BIO" screen until the keyboard is recognised and even then it is not a sure way through into the BIOS.



Given the annoying circumstances of the above, I still managed to get into my BIOS (typically after 5-10 restarts) and once I am in I am trying to enter into the Boot priority to turn the USB as my preferred boot option and it is not recognized, the only option is my HDD. Again, annoying.



Can anyone help with the above?
