Troubleshooting
This chapter answers common troubleshooting questions you may have when using the
RMC-8356.
What if the RMC-8356 does not boot?
Several problems can cause a controller not to boot. Here are some things to look for and pos-
sible solutions.
Things to Notice
:
•
Which LEDs come on? The power indicator LED should stay lit. The hard disk drive LEDs
should blink during boot as the disk is accessed.
•
What appears on the display? Does it hang at some particular point (BIOS, Operating
System, and so on)? If nothing appears on the screen, try a different monitor. Does your
monitor work with a different PC? If it hangs, note the last screen output that you saw for
reference when consulting National Instruments technical support.
•
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?
•
Has the system overheated? If the Overheat/FanFail LED is lit, this indicates overheating.
Unplug the AC power cord from the controller and allow it to cool down before powering
it on again.

Make sure the CPU and memory modules are properly seated in their slots.

My RMC-8356 boots fine until I get to Windows, at which point I cannot read the screen.
This may include garbled output, white screen, black screen, or an out of synch message
from the monitor.
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 RMC-8356. As Windows
begins to boot, hold down <F8>. You should now be able to reset the video driver to lower set-
