• What has changed about the system? Did you recently move the 
system? Was there electrical storm activity? Did you recently add a 
new module, memory chip, or piece of software?
• Refer to your chassis user manual for additional troubleshooting steps.
Things to Try
• Make sure the chassis is plugged into a working power source. 
• Check any fuses or circuit breakers in the chassis or other power 
supply (possibly a UPS).
• Make sure the controller module is firmly seated in the chassis.
• Remove all other modules from the chassis.
• Remove any nonessential cables or devices.
• Try the controller in a different chassis or a similar controller in this 
same chassis.
• Clear the CMOS. (Refer to the System CMOS section of the 
NIPXIe-8106  User Manual.)
• Recover the hard drive on the controller. (Refer to the Hard Drive 
Recovery section of the NI PXIe-8106 User Manual.)
For more troubleshooting information, refer to the NI PXIe-8106User 
Manual. The manual is in PDF format on the recovery CD included with 
your controller and on the National Instruments Web site, ni.com/
manuals.
What If I Cannot See the Video?This problem usually results from having the video card output set past the 
limits of the monitor. You will need to boot Windows in Safe Mode. To do 
this, reboot the controller. As Windows begins to boot, hold down <F8>. 
You should now be able to reset the video driver to lower settings. Try 
setting the resolution to 640 × 480 and the refresh rate to 60 Hz. Once you 
reboot, you can raise these values again, using the test option in Windows. 
These settings are accessible through the Advanced tab of the Display item 
in the Control Panel. Alternately, you can try a different monitor, 
preferably a newer and larger one.
If the system has been booted without a monitor attached, the 
NIPXIe-81 06 may have defaulted to the video output connector being 
disabled. Press <Ctrl-Alt-F1> to re-enable the video display in Windows. 
Press <Ctrl-Alt-F4> to re-enable a DVI display. For more information, refer 
to KnowledgeBase 3OHCFRD8 at ni.com/support.
