Hi People not sure if anyone can help but here goes

building a new pc and I think my motherboard has a fault

i built it changing the jumper to make sure it is running at 333mhz. When I boot it up nothing happens on screen


CPU fan and PSU running and HDD and power LEDS are constantly on, you can hear CD drive spinning but nothing after that whatsoever, tried 3 different monitors and a external agp graphics card

any ideas?
