This machine is completely stuck on the post screen. On the bottom of the screen, it says press delete to enter into setup, bu tno matter what I press, it won't go anywhere. It is a brand new mobo with a brand new sempron cpu. I read around and believe it may need a bios update in order to use the sempron, so I downloaded an update from website, and put it on a floppy. Problem is, I cannot get it to boot into the bios, boor from floppy, or go past the post screen at all. Please help.
