Guys, I need your assistance with an issue related to a newly purchased graphics card — Gigabyte GeForce RTX 5070 Ti WindForce OC.My system is based on an ASUS ROG STRIX Z690-I GAMING WIFI (LGA1700, DDR5) motherboard.Previously, I used a Gigabyte RX 6700 XT Gaming OC, which has always worked flawlessly in this system and continues to operate without any issues when reinstalled.After installing the new RTX 5070 Ti, the system fails to output any video signal. The motherboard’s POST indicator gets stuck on the GPU stage. In the BIOS, the PCIe x16 slot shows “Not Present”, meaning the motherboard does not detect the card at all.Here is what I have already tried:Updated the BIOS to the latest version available, manually forced PCIe modes (Gen 3 / Gen 4 / Gen 5)Enabled and disabled CSMPerformed a CMOS reset, verified all power connections (both 12VHPWR and dual 8-pin through the included adapter)Confirmed sufficient PSU capacity (1000W), Reinstalled the GPU multiple times, Confirmed several times that the graphics card is fully and correctly seated in the PCIe x16 slotDespite all these steps, the system still does not detect the GPU. Both the integrated graphics and my older Gigabyte RX 6700 XT work immediately and without any issues in the same PCIe slot.Could you please advise on further diagnostics or confirm whether this behavior may indicate a defective graphics card?Thank you in advance.
