Most likely the cause of this is a defective 3.5" Drive.
Replace the drive and see if the problem is cured.  Cost around $20US.

If the problem persist then the problem is with the MotherBoard which is obviously more expensive.  This is the reason I would start with the 3.5" drive.
Check the power connection to the back of the floppy to make sure it's snug.  Also, look at the flat cable connected to the floppy.  The first thing to notice is that there is a twist in the cable.  The floppy must be using a connector after the twist.  If this is the case, try reversing the way it is plugged into the drive.  You can tell that the flat cable is facing the wrong direction if the little LED light on the front of the drive is constantly on.  If all of your cables are correct and it still fails, try going into the CMOS setup and making sure the system is set to use the correct type of floppy drive.  If all of this fails, it's time to invest in a new drive.  Celtics is right, it will cost only about 20 bucks.
If problem is on the motherboard you could try a floppy controller card and disable controller on the motherboard. If it works it would be cheaper than a new motherboard.

How do U do this?
"If all of your cables are correct

system is set to use the correct type of floppy drive".

I went into CMOS setup and it says
A and B have 3.5 disks....can't
see any options about enabled and
unenabled drives. NOVICE here!

Note, I can still use the drive if
I bypass BIOS using F1 and
also if I click (in windows)
"Drive A" I get an error message
that drive is empty. When I click
on "Drive B" then I can read the
floppy in the drive. Weird.

What can I do?....thanks for your

How to fix this problem:

Go into the CMOS Setup. Next to drive B, use the Page Up key until the drive turns to 'None'. Reboot the computer. If you still get the message, go into the BIOS again, and select BIOS FEATURES. Find where it says 'Swap Floppy Drive Letters' or similar. Make sure it says disabled.
