For a start try to put the GPU in the primary slot on the motherboard. If the system does not see GPU it is necessary to check BIOS and driver. You also need to test that GPU on another computer. After that, you can check the performance of the riser. But this happens very rarely. Need more specifics to give you the right advice.

Thank you.
I already try to put the gpu in the primary slot on motherboard the VGA runing normal.Also test this GPU with another computer the VGA is normal.
Only run the VGA with riser card the system can't detect.
