Is there Motherboard diagnostic software for PCIe slot available?

Hi.
First, the question. Is there any diagnostic software available to let me know whether my PCIe slot is working?

Just thought maybe someone here, might be able to answer.

P8z77-v motherboard for i7 2700k.
HD6970 gpus.

I used to run Crossfire in Windows 7. Worked great. I pulled a card and let someone else use it for awhile.
I tried to install it again and now, I can't get crossfire to work.

Since then, I have...

upgraded to win 10
Tried each card individually in the 16x slot. Both video cards work.
Tried each card individually in the 8x slot. All I get is a black screen
i can't try the 4x slot, my cards are too thick & the PSU gets in the way.
enabled crossfire using my iGPU & HD6970 and it worked.
*when I install both cards, I do not get an option to enable crossfire
*MSI afterburner, GPUz, and windows10 does not show that I have 2 graphics cards installed.
My fans for the 2nd gpu is working
I uninstalled AMD drivers using the AMD driver uninstaller. Re-booted. Then installed the most up to date drivers available for my graphics card. Tried this a couple different times. Once with each card installed in the 1st pcie slot.

I have done searches, but every post says: "try this or try that..." none answer the question of... Is there any diagnostic program to tell me for sure, that the pcie slot is not working.

There are troubleshooting tools available, but they involve plugging in a piece of hardware into that interface. Your bios controls whether it will see the device in the PCIe slot or not. Also the spec's for your motherboard for what type of PCIe slot that is, determines if it can handle that card, along with your power supply.

Thanks for the response. The point is moot. Unfortunately, under windows 10, I get lower frame rates in my primary game so I will be uninstalling.

Thanks.

You will have to update the video driver and also tweak the settings for the game. 10 optimizes the RAM, CPU and without enough power for that card or enough RAM on the card or slow APU/CPU/GPU on it, yes the rate can be off some.

There are some dedicated gamers on this forum, you may want to have this post closed and open a new one over athttps://www.tenforums.com/graphic-cards/ if you have not done already.
