Robot not Listening to Code (LabView)

[SamJr.]

Ok, so, yesterday, everything was working. Even Autonomous, more or less. This morning, we came back in to work, and the robot was simply unresponsive. Eventually, we succeeded in connecting, but the code seemed to be completely ignored. All throughout the day, we tried everything we could think of, including switching out the C-RIO. Symptoms include: flashing Talon lights, brief spurts of activity in the drive train before a return to silence (without any input from us), and random motion in other motors. Probing all of the lines in the code proved that there were no errors. Replacement of the C-RIO, most of the PWMs, and old code that we know works had little to no effect. We've never seen anything like this before. Any help, soon, would be greatly appreciated.
