Asrock ALiveNF6G-VSTA Motherboard.\r\nUnable to boot to OS

first disconnect ALL cables except power suppliy and frond panel switch. Startup and see if goes further.
dont forget to disconnect the front panel usb cables also !!!
if it goes better, connect he keyboard, reboot and enter bios to see.
etc etc

if it still hungs up at the start with all cables disconnected then a major chip on your motherboard is burnt (maybe the disk controller).

sorry i dont think a solution oher than buying a new motherboard.
