Dear Darren,
This sounds like there is a problem with your chassis supplying the power required for all of your PXI modules. This could indicate either a problem with the power supply on the chassis itself, a problem with the PXI backplane being shorted, or a problem with one or more of your modules. If possible, I recommend testing this system with a different PXI chassis.
If a second chassis works, then we know the problem is with the first chassis. In this case, I recommend checking for bent pins on the backplane. You can also send it in for repair.
If the second chassis does not work, then we know the problem probably is not with the chassis. I recommend testing each card. One of your modules could be shorting the backplane. I recommend testing the s
ystem with each module one at a time. Place each module in each slot in the chassis to see if any combination of modules and slots makes a difference. Once you verify that each module works, you can then test to see if a certain combination of modules causes the problem. The goal here is to determine which module or modules is causing the problem. We need to find out which module is either shorting out the backplane or is drawing too much power.
This could also be a problem with the MXI-3 connection or the PC. I recommend testing this system with a different PC. You may also consider upgrading your PC's BIOS.
If you want to send in your chassis or PXI modules for repair, you will need to call in. In this case, go to http://www.ni.com/support and generate a phone support request.
