Hello,
I have a problem in my S2600CP2J board, firstly I installed a GPU (MSI GTX 760 OC) on the x8 blue PCIe slot the second one after the x16 slot, when monitor connected with the new GPU, the screen not show anything during boot (no POST or windows boots screen and no signal to monitor) and the monitor turns on after windows enter to the login page.
After reviewing the BMC log I see some errors related with PCIe, the picture is attached below
