Ok, first things first, do you have a Floppy Drive on your PC ?
If no, go to Bios, in the Basic section remove the floppy drive.
If yes, go to Bios, in the Basic section and set error to ignore floppy. This will bypass fixing the problem and let you use PC.
You can check your floppy data cable to make sure it's inserted properly with no broken teeth and that the cable is connected the right way (not inverted - it will have light on all the time when it is inverted), same cable inserted right on MB.
Most likely the key to enter Bios will be DEL, some have F2 or otherwise specified.
