Possible that the keyboard interface is fauty, the linking cord is worn out or an error at the connector.
If you can open to remove the board and reset the connect it will confirm on any loose leads.
if not the keyboard can be faulty. Try and attach a wireless keyboard using the USB port to confirm on the status of the mother board.

When i turn my compter on to re-download windows 2000 it says keyboard error but wont read the d: drive. but the keyboard works except my f keys

Since windows 2000 is quite old now, I suggest using a PS2 interface keyboard USB may work.

Also your keyboard may have a F-Lock key, make sure its pressed when you boot up.

Locked Metrologic MS9520-37 (keyboard wedge) after unintentional programming

You programmed it for usb interface, but the scanner is keyboard wedge. Try pointing the scanner at the "recall defaults" barcode in the manual as you plug the scanner back in.
