coputer worked fine for three months then used the evil norton antivirus update

and there it was two floopy icons and they work as if they where both a drives BUT TRY TO USE THE "B" DRIVE and the pc hangs.
DONE the device manger thing and wont resolve

tried the bios nop luck because it only is seeing one drive a
