ethernet and booting problems

I finished building a new computer. i have a striker extreme mobo and installed vista 32bit home premium. I have had it working for about two weeks. it has two gigabit connections built into the mobo. it would only do 10 Mbps whereas my old system would do 100 Mbps connected to my router. I have tried both gigabit connections, i installed the latest nvidia drivers with no success.

I then tried to update the bios. the bios showed that it was successful in updating and now it won't boot. I have two SATA drives installed. the hdd is listed as the first boot and the raptor is in sata slot 1 which has vista installed on it. I reverted back to the original bios and it still won't boot. it gives me the won't book, insert boot disk message. :cry
