Odd DAQ problem after rebooting PC

I have one PC running an LV app (LV 8.6, DAQmx 8.7.2). After a system reboot, the readings from my DAQ card (PCI-6251) are garbage. If I stop and restart my application (but don't reboot the PC) the readings are fine. I have the same app running on a couple of identical setups and it runs fine. So that would seem to point to a hardware issue. My app resets the DAQ card before setting up all my tasks. I tried reloading my app and DAQmx. I haven't been able to try a new DAQ card yet.

Can anybody think of an explanation for this odd behavior? Does it seem to indicate a problem with the DAQ card?
