Hello, please help me. I can't find a solution to the problem. The problem is that the system does not see a discrete video card (rtx 3080ti) on the motherboard biostar tb250 btc, that is, when connected, on the start screen when booting, it says that there is nothing in the pcie slot and the task manager does not display (only video from the processor). I looked for a solution on various forums, changed bios settings, tried to connect other video cards, but still the system does not see any.
