help installing new motherboard
 

ok ive just installed an asrock Socket AM2 for AMD Athlon™ 64FX / 64X2 / 64 and Sempron Processors NVIDIA® nForce3 250 motherboard.

when i turn on the pc i get no power. the main problem seems to be the jumper setup and onboard headers and connectors. there are more connectors than sockets. i have the manual but i totally lost on where they all go

can anyone help
