If your cRIO is freezing, hook up a null-modem serial cable and use hyperterminal or another terminal program to see the diagnostics from the kernel. It will often tell you what is wrong, or at least give you info so that people can help.

If you truly think you have a problem with the cRIO, try isolating it. Reimage it to the latest image, make sure it is a fresh battery with nothing else hooked up that doesn't need to be, and run an example program. If that crashes, freezes, or misbehaves, contact NI tech support by phone.

If it doesn't, then start adding things back on somewhat slowly.

You aren't going to get this debugged without more isolation and more information.
