    Default Gigabyte GA-EP45-UD3R high pitch noice when exiting BIOS and restarting

    Whenever I exit my BIOS or restart my computer, a high pitched tone comes from the mobo for about 4-5 seconds. It happens before the computer begins to post. The screen stays black while it makes the noise and then everything starts up (note: my computer case doesn't have a speaker so it has nothing to do with the beep sequence). I have had no problems with my computer but am wondering if I should be concerned about this noise or if it is normal.. because I have not seen anyone else mention this and figured that if it was common, other people would ask about it too. Any insight as to what may be going on would be appreciated!

    Hi secondfall,
    Welcome to the forum
    I'm running the same board but must admit i've not heard a noise like you described.
    Have known boards make noises in the past, usually from capacitors or chokes. I don't think this board will give those isssues.
    Might it be a fan ? I have noticed that if you have the CPU fan plugged into the PWM header, the fan is slow to start and come up to speed on startup. Perhaps it's from that?

    Edit:
    THis might be of interest and relevence Whining X58

    Hi Supershanks, thanks for the reply. It's not a fan, my CPU fan is plugged into the correct slot.. the fan does not start immediately but my understanding was that that's normal for this board. I have a 750W PSU, and it's definitely not a whining sound, it's a steady tone. Maybe I just need to send for a new board :(
