Additional Information
If the issue occurs with a PCIe card, also make sure you test different PCIe ports of the PC. The PCIe cards that NI provides are compatible with x1,x4,x8, x16 PCIe Ports (you can check the specifications of your device to confirm this in the Bus Interface section). There are cases where the PCIe cards work only in one of these ports depending on the motherboard.
If you are using Thunderbolt connections (such as the PXIe-8301) to control your NI hardware, additional Thunderbolt troubleshooting steps may be needed. These can be started at
