Its been awhile but here is an update... The PC fixed the above reboot issue but as time went on we started having the "reboot issue" on the other 13 stations and replacing the PC did NOT always fix the problem. So we started using the PCI-8335 MXI-3 (fiber optic) and that took care of the issue. It is thought that the copper wire was creating a ground loop and pulling down the PCI BUS but there was no further investigation on the matter.
FYI...The PCI-8335 MXI-3 card has been discontinued and the NI replacement is a copper wire only...
