Hi all. I breadboarded my new build using the Gigabyte B360M DS3H motherboard. All fine. Put into Corsair spec-01 case. Normal short beep on startup then a very (what can only be discribed) as a long "harsh, rasping, distorted" beep. All appears fine. I can use pc ok, no error or warning messages. Ram and drives are fine. Just want to know what this second beep means.
