VIs stop running after two seconds

[ErikRantapaa]

On one laptop I am having a problem with VI's terminating a couple of seconds after deployment.

For instance, when running the Analog Input example I can deploy the VI, and it appears to run, but then it just stops after a couple of seconds. No error dialog box comes up - apparently the VI goes from running mode to stopped mode.

Other symptoms:
- the status led on the cRIO will start to intermittently blink three times (i.e. blink-blink-blink, pause, blink-blink-blink, pause, ...)

- the driver station indicates there is no communication with the cRIO

- if I single step through the code, I never make it through one iteration of the inner while loop; the top branch of the OR operator connected to the stop condition becomes true right away; if I remember the VI correctly, this is an error condition, but I haven't been able to figure out what the error is.

However, I don't have these problems on another laptop. The main difference between the two is that on the one that works I installed Windows 7 myself and the one that doesn't has a factory installed Windows 7.

Any ideas of what the problem is? Is there more I can do to diagnose the problem?

Thanks!
