Random rebooting with LabView application

[benegin]

I am having problems with my computer rebooting when I run a LabView application. I am using LabView 6.0, Ni Daq 6.8.OF9, MAX 2.0.3.6. My application uses an AI one pt.vi inside a timed while loop. I read from 1 to 8 channels. I am using a SCXI 1000 with a SCXI 1125 and an SCXI 1327. My PC has a PCI-MIO-16XE-10. My application is a program that I use on many LabView applications and runs good. My problem started when the hard drive was replaced and I reinstalled all the software. Now when I try to run this application the computer will reboot at random. Sometimes as soon as I start the application other times minutes into the data collection. The IS department could not find anything wrong with the PC.  Any idea what is causing this or what I can try to fix the problem?

Hello benegin,

The problem you are describing is typical of either a hardware conflict or corrupt driver.  Perhaps when you installed you new hard drive (and reinstalled all your drivers/hardware) you received conflicting devices.

You mentioned that this one application causes your computer to crash.  Does your computer reboot/crash when running any other application, or any other VI inside LabVIEW?  If other LabVIEW programs cause your computer to crash do they require NI-DAQ VIs, or does it seem to be more related to LabVIEW instead of your DAQ device?  For example you mention that you use a timed loop and file I/O.  If you just use a timed loop or just do file I/O in a VI does this cause your computer to reboot?  If the reboot is related to your DAQ device, can you cause the same crash when just using Measurement and Automation Explorer (MAX) test panels? 

If you believe the problem is related to your devices (or drivers), you can try upgrading your version of the DAQ driver.

Jesse,

Thank You for the help. I installed the NI-DAQ 6.9.3 and the program has worked without a glitch for a day. The problem seemed to only show up on this one program but it was too intermittent to know for sure. MAX test panels always worked.

Howard,

I think from your post that upgrading to NI-DAQ 6.9.3 fixed your problem.  If not please let us know the results of the tests I mentioned in my last post (i.e. Does your computer reboot/crash when running any other application, or any other VI inside LabVIEW?).

Have a great day,
