So this laptop is BRAND new, 1 week in. I started to get two beeps every 15min no matter what I do, and I don't know how to fix it, I've muted everything and it's still there, it wasn't the system sounds, it wasn't any program, but the beep is still there, is there any solution to this problem? I've become so sick of hearing the two beeps continuously for 15 minutes.
