Hi rpg217,
A little more info please :)
Is the hard drive detected in bios?
Is the Windows 7 install disc original or burnt?
What on screen messages do you get when you change the boot sequence then reboot?
Have you made any hardware changes?

What model gigabyte MB you got

As theog's first link instructs, try booting with a linux boot/install cd inserted. Use the fdisk function to delete ALL of the partitions.
