With NI-Daq installed the computer reboots anytime Measurement and automation is opened. I have tried NI-Daq versions 6.8, 6.9.3 and 7.4. It doesn't matter if the PCI-MIO-16E-4 card is installed or not. If Ni-Daq software is installed, the computer will reboot when Max is opened. Uninstall Ni-daq and no issues are noted. I can communicate with a PCI-GPIB card just fine. This is on a Windows 2000 machine and it worked fine. Came in one morning and this just started happening.
