I checked my manual for what the beeps mean when you power on the MOBO and I didn't see anything. After looking at the newegg youtube tutorial i know that just one short beep means that everything is A-OK. But when I do it I get a beep, then maybe 1-3 seconds later I get another single beep and the UEFI BIOS comes up. Now, I do have my mouse and keyboard plugged into the motherboard because I wanted to play around with the BIOS. Does the mouse and keyboard affect the signal beeps or is there another reason why it makes another beep. (Note: When the ASUS splash screen came up I didn't get any error message whatsoever. It booted up and asked me if I wanted to enter the BIOS) Is this something I should be worried about?
