Multifunction DAQ
Installing NI-PCI 6221 DAQ
that bluescreen error happened to me too, in my case, i had two os winxp and in one of them, the fist one installed on pc the card worked properly, but in the second one bluescreen appeared, perhaps something bad happend to os configuration during rollback, i've worked ni pci 6221 with 32 and 64 bits os and works properly. i recomend you to work with win7, the default os of your computer or get a good winxp installer so you can fix os with os assistant, or use a virtual machine to deal with your daq.
i hope you find it usefull
