I recently upgraded my PC by swapping out my old AMD 6600 graphics card for a new NVIDIA RTX 5070, but my system isn't recognizing the new card at all. I've followed several troubleshooting steps: I removed the old GPU, installed the new one in various motherboard slots, used DDU to uninstall the previous drivers, double-checked the power connections, and updated my BIOS. However, I still can't install any drivers for the RTX 5070 since it isn't detected by my PC at all. I get no image output from the new GPU and have to rely on integrated graphics to troubleshoot. I'm wondering if anyone has suggestions on what else I might be missing or if it could be a faulty card.

I recommend testing the GPU in a different PC if you can. If that’s not an option, boot into safe mode, run DDU to clean drivers, and ensure that Windows isn't trying to auto-update with incompatible drivers. Also, check if your card is appearing as an unknown device in Device Manager—sometimes it shows up there even if it's not functioning properly.
It might be a case of the graphics card being dead on arrival (DOA). I've had that happen before, where a new card just wouldn't work. If possible, you might want to consider getting an exchange to see if a different card works better.
This sounds like a driver issue. If you have an HDMI port on your motherboard, try plugging your monitor into that temporarily. Sometimes it's easier to get the old drivers cleaned out that way. If removing the old card and drivers doesn't work, there might be something wrong with the new one.
