Hi Sean,
Have you tried this card in another PC? Also does the system crash with the card in, but while it is not connected to the MXI-4 that is in the chassis? What other devices do you have in the PXI-1045? Please provide me with a detailed descriton of your hardware set-up as well as the error you are seeing when you boot up your PC. For instance what does it say on the screen, when does the system crash, etc. One thing you might be aware of, but make sure the chassis is powered on prior to booting up your PC.
