If you determine that one PCIe card is interfering with the operation of 
another card, first try reorganizing the cards on the motherboard. 
Moving the cards around can change the order in which the cards are 
configured by the system during power-on. This will go a long way 
toward resolving module conflicts. 

As previously stated in 

, it remains 

necessary to power up ALL Expansions Systems BEFORE you turn on 
the computer. This will ensure that your power-on software can read all 
available buses and properly configure all installed PCIe cards. 

Obviously, the reverse also remains true for shutting your system down. 
The computer must be shut off BEFORE you attempt to turn off your 
Expansion System(s). 

When trying to troubleshoot problems with PCIe cards in a multiple 
expansion system configurations, it is vital to correctly determine the 
nature of the problem. Therefore, the first task is to identify the card or 
chassis having a problem by using the Windows Device Manager, or 
Apple System Profiler. Refer to the first part of this Appendix for more 
information on identifying hierarchical levels in multiple expansion 
system configurations. 

Problems with 3

rd

 Party PCIe cards might only be traceable once you 

have identified the expansion system containing the problem card.  

Below is a flow chart offering a troubleshooting approach when multiple 
expansion chasses are involved:
