Please check the voltage input (measured at the cRIO connector). If you contact NI to get a replacement make sure you send in your broken cRIO quickly so we can take a look. Killing a cRIO is very rare, and so far has been impossible to reproduce in the lab, so when you call in please provide as many details as possible including your configuration, what was happening at the time of failure, length of time you've been using the cRIO, etc.
