PCI 6503 The device is not responding to the selected base address

[ChadVI]

When trying to enter the test panel within NIMax, the app gives the error above "The device is not responding to the selected base address."  I have tested the card in a different PCI slot and the different computer.  I have added this card to 7 different PCs, and this is the first one to have a problem.  I have tried a second card and got the same result.  Are there any more trouble shooting procedures that I can consider?   If not, I will attempt to return the cards that were purchased only 4 months ago.

Hello ChadVI,


The resources that Kal linked to are a great start to troubleshooting
this issue. You mentioned testing the 6503 on several computers in addition to
this current system, with only this new system failing. Have you confirmed that
the device drivers are up to date and the operating system is current with
service packs?


Have you attempted to install the 6503 again in one of the previous
computers which you know to be working? If the board works on several computers
then I am leaning towards there being an issue with the way this new system is
setup.
