Motherboard does not beep when PC boots up

My Gigabyte GA-8INXP motherboard does not beep when the PC is turned on and all I get is a blank screen. All the fans and lights start and I've tested all the components and monitor which all work. The only things that I can think of which are not working are either the motherboard itself or the CPU.

Can someone tell me why the motherboard doesn't beep (as it always does) and if this due to a problem with the motherboard or the CPU.

Thanks.

Here's a picture of the CPU which seems fine apart from the bit inbetween the pins.
