Bluescreen problem related to nipalk.sys when restarting PC

[QHKLA]

Hi,

Just recently everytime I restart my PC, whether there's an NI application running or not, I always get a bluescreen error related to nipalk.sys. The error is "page_fault_in_nonpaged_area". Has anyone seen this before? I am only using Labview 2018 (32-bit) on my laptop since early this year. But this problem only happened from yesterday.

Thanks!

If it is a pretty new labtop (13 or 14 generation Intel CPU) it may be that a recent update to the System or other drivers enabled some new virtualization feature of those CPUs that was in previous driver releases not used. The NI kernel drivers from 2018 can't even know about such features.

There is a chance that upgrading NI-DAQmx or some other driver you are using (or at least did install) might help but it is a somewhat tricky operation. Because you use LabVIEW 2018 you could not go higher than drivers from 2021.8. That might or might not be enough to remedy your problem.

Thank you! After I installed DAQmx 21.8 (although not using it), so far I didn't see the blue screen problem.
