well i do have all ready speaker connected on the motherboard but they are connected to the back panel. HD AUdio. i did disconnected it but nothing was changed, beeping continues. the source of beeping is somewhere sound bridge i cant locate it exactly, but when i am moving with the mouse,i can hear the noise mostly.its sound something like a load... i did disconnected the hard drives too, but nothing. Perhaps I should update new BIOS?
