PCIe on Arria 10 works on one host machine and doesn't work on other host

Hi,

I have connected my HOST (Workstation Desktop PC ) to arria10 SOC development kit through a PCIe cable Connector.

After Programming example design (PCIe AVMM DMA (AN690.pdf)) (EPCQ or sof) any way of configuration in Arria10 soc kit. When I poweron My Workstation PC, The kit does not show up in device manager.

I tried for simple Arria10 PCIe hard ip by exposing its main signals(Reset, Tx, Rx, Refclk). Here also it does not show up in device manager.

My host Desktop PC and Arria 10 SOC kit are connected by PCIe cable, where I have removed Power lines.

I am programming by giving external power supply and once done LED goes high I switch on my Host PC.

attached snapshots of my hardware setup.

and modified example design PCIe AVMM DMA and simple PCIe arria 10 hard ip design .

Please have a look and give inputs where I am going wrong.

Thanks,
