Hi Randy,
Is this a National Instruments MXI-3 card and PXI chassis?  If so, what model?  Is there software (other than the driver) that came with the PX2000-107 board?  If so, have you uninstalled/reinstalled the software?  You could also try the uninstall/reinstall of the driver as well.  Can you see the PX2000-107 board in hardware device manager and does it have a yellow exclamation mark next to it?
Hope this helps!
