dive a and b not being recognized

drive a (3.5) and driveb (5.25) are not being recognized when a disk has been inserted?
all i get is error dive not recognized.  The lights are on all the time and when the computer starts up i do not hear a beep.  With a system disk it still boots right to windows 3.1 not dos. I dont hear the disks spinning just light is lit up??

This generally indicates that the drive cable has been reversed when connected to the motherboard.  On the ribbon cable coming from the drives (it is usually grey), one side should have a red or red spotted wire.  Like this:

                This wire is red or red spotted.
Anyway, most likely either the connection to the motherboard is reversed or the connection to to drives is reversed.  Check to make sure that this cable is plugged in with the red wire on the side of the motherboard connector marked 1, and that the red wire is on the side of the floppy drives connectors that has a 1.  If the cable is reversed at any of these points, the floppy drive lights will stay on all the time and the drives will not be seen by any software, not even by the computer itself.

hop this helps!

Have you had a look in the BIOS settings to see what drives the machine thinks you have?
Sometimes if the settings here are incorrect or have been corrupted, especially on older machines, the floppy drives don't behave properly.  The boot order of the drives is set here also, ie. C: then A: or A: then C:
Did the A:/B: drives ever work - if so, what has changed since then?
