Hello,
When you say your computer locks, does that mean just your VI or all applications?
It's possible that LabVIEW is consuming much of the CPU, especially if it's the only application running, and you don't have any timing/wait functions in a loop. In such a case you can imagine that code is executing as fast as possible, and if nothing else is running on the machine, it can appear as though things lock up.
Try using the wait until next ms multiple or wait ms function.
Best Regards,
