Hi,
For PCI-GPIB boards the following steps may help to troubleshoot and resolve this issue.
1. Confirm that the GPIB cable is not connected to any GPIB device. If it is connected to the GPIB device, disconnect the cable and run the Troubleshooting Wizard.
2. Install the latest version of the NI-488.2 hardware driver. The driver must be installed before hardware is inserted into the computer.

4. If you have another PCI slot available in your desktop, move the PCI board to that slot. After moving your GPIB device, run the Troubleshooting Wizard.
5. For Windows 95, 98, 2000 and XP, go to My Computer�Control Panel�System. Click on the Hardware tab and then the Device Manager button. Verify in Device Manager that the GPIB hardware has been detected by the computer. Right-click on the GPIB device and choose Properties to verify that the hardware has been installed correctly. Click on the Resources tab to see if there are possible resource conflicts. Your device may have an interrupt (IRQ) conflict with another device. For information on how to resolve IRQ conflicts with third-party devices, refer to the following websites:
