Sorry to hear that you are having issues on one of your R815's. The problem could be one of the PCIe devices, or one of the PCIe slots itself.
This system has two PCIe slots directly on the I/O riser (slots 3 and 4). There are also two Risers… Riser1(Center) which has PCIe slots 1 and 2, and Riser2(Left) which as slots 5 and 6.
Drain flea power by unplugging the system and holding the power button for at least 15 seconds. Remove all PCIe devices and try to Post. Ensure that you re-seat all Risers also.
If you are still getting an unsuccessful post, you should move to minimum post to ensure there is not another fault that is falsely pointing to the PCIe. However, is most likely a PCIe device fault, or a fault on one of the Slots on the risers, or I/O board.
The minimum components to allow the PowerEdge R815 to complete POST are:
System board
I/O board
Risers
Processor (CPU1) with Heatsink
Power Supply
Power Distribution Board
At least 2 DIMMs in sockets A1, A2 (lock-step pair) to POST
Thank you very much for replying and your helpful suggestions. We removed all PCIe devices and went to a minimum post, however we are now encountering the problem of our machine not being able to boot past the Dell logo screen. We replaced the PCIe devices, reseated the risers and all the ram and made sure everything was securely connected but we are still unable to boot past the Dell logo screen.
Just to clarify the minimum to post. It is often overlooked that the KVM, DVD optical drive, iDRAC6 enterprise adapter (if applicable), and backplane all need to be disconnected as they too can cause a short. If you already disconnected those devices during your minimum to post test, then the fault lies within the core components. To further rule out the CPU or the DIMMs, you should swap in the other proc into CPU Slot 1 and another pair of DIMMs.
Also proceed with clearing the NVRAM. See the attached jumper settings:
If the problem further persists, then it is likely that you will need to look at replacing the I/O board and/or the Risers.

Please let us know how that goes.
