Try this: Start tab>Run>type msconfig then ok>go to startup tab & disable or uncheck all unnecessary programs.

Did you already swap the floppy cable w/ a known good one? If not, try it. If it didn't work. There's something wrong either w/ the controller or power connectors/cables. Try this one, if its not recognized in the OS but its recognized in the bios, reinstall your OS but dont format. Hope these would help you!
