I recently built a new PC and installed Windows 11, but I'm having trouble with my graphics card. My GTX 1070 Ti won't work, and neither does my older GTX 1060. The only card that seems to work is an old GT 620, which doesn't require a power cable. My power supply seems fine, so I'm not sure what's going wrong. Any suggestions on how to troubleshoot and fix this issue?

When you plug in both GPUs, does anything happen? Fans spin, lights flash, or any beeping sounds? If you’re getting some signs of life, it might narrow it down, but I'm leaning towards that power supply theory too. Maybe a trip to the store for a new one could be the answer!
Have you considered checking the power supply? It might be worthwhile to test it with another one if you have access to a spare. Sometimes the PCI-E power connection can fail, even if everything else seems fine.
