BIOS updates sometimes address that and then again, the board is new and could have a defect. Why not pester the seller about this for an exchange?
I have just built a computer and I am running Windows XP home, with AMD 3000+ chip (754 socket) on a ECS nForce3-A motherboard and 1GB ram with a Seagate 7200 rpm 160Gb hard drive. Every time I turn the computer on it requires me to manually select F1 to go forward and boot up or DEL to enter setup. All of my other computers simply go through the process and boot up! I am not real good at this techmical stuff and could use some help in solving the problem. Any help is greatly appreciated.
