Issue Details

I have cDAQ-9139 running on Windows Embedded Standard 7 (WES7). It does not boot into operating system (OS).
I see black screen with flashing cursor on the upper left corner when powering on the device. Only power LED is lit.


This behavior indicates OS corruption or memory issue. Re-installation of the OS may solve the problem.
Refer to instructions on the NI cDAQTM-9138/9139 User Manual, pageĀ A-2, chapter Installing an Operating System.
If instructions on the user manual don't help, contact NI technical support.
