You can use the page here to help identify the device in question, as well you could also take the server to its minimum to post configuration, and then test if the issue continues under that configuration. If not then individually add the removed devices back until you identify the culprit.  Minimum to post for the R710 is removing everything internally and externally but the following;

 

System board
Risers
Processor (CPU1) with Heatsink
Power Supply
One stick of memory in dual in-line memory module (DIMM) slot A1
Control Panel with cable

 

Let me know what you see.
