Your BIOS is corrupted
the fact that its looking for a floppy disk is very fortunate for you
it means you can easily flash the BIOS
go to your board's manufacturer site and download the latest BIOS for your board
find out if its Award or AMI BIOS, and flash it accordingly (each BIOS is flashed differently in case of a bios crash, there instructions for each one in MSI's site - www.msi.com.tw )
oh, i forgot, there could be a much simpler solution - try reseting the CMOS with the reset jumper on your board (documentation should say where it is located), and if that doesnt work try removing the battery from your mobo, wait a couple of minutes and put it back)

good luck
