Hi, computer just died recently, it has 4CoreDual-VSTA( Asrock FSB1066) in it, all fans are working but it keeps emiting 3 long beeps all the time, and when pc is turned off but connected to power, i keep hearing continuous, loud high pitch noise in my headphones. Is this the failure of the motherboard or something else? I tried placing different working RAM sticks, but i get the same result.
