[Solved] The computer does not detect the card - the PC can not see the graphics card, th

Hello
I got my motherboard ASRock Z68 Pro3 and Intel i5-2500K from my friends so I decided to take my computer

Unfortunately, when connecting the monitor to the graphics card, i.e. GTX 1050, the image on the monitor is not displayed and the monitor itself is at rest (only the sound of Windows loading is audible)

I downloaded GPU-Z and checked in the device manager and this 1050 m is not found in the same inegra.
I checked the primary BIOS is set correctly ie PCI-E

The graphics card on another computer works without a problem, as does the CPU and motherboard
I even changed the BIOS from the manufacturer but it did not help

I tried to reset BIOS and CMOS earlier without results: /

That's how the whole album looks like, if you can tell me because maybe something else needs to be connected: /

Tomorrow morning, I am still purging with compressed air and let me know

Problem solved
And here I will write what I did:

I put the graphics card in the slot, but I connected the monitor to the integrated. In the device manager -> the graphic detected only the Intel, so I clicked right -> properties and turned it off.
The screen blinked twice and appeared normally. Then I turned off the computer and turned it on. In the manager he detected the NVIDIA card (1 success)
Then I downloaded the drivers and tried to install, the first attempt was unsuccessful, I downloaded the GPU-Z which indicated that it sees my card, so I restarted the computer and restarted the driver installation, this time it worked.
Everything is going as it should, and all those who somehow wanted to help, thank you
