New-built computer not detecting GPU

Hey all! First time pc builder here, and it’s gone really well, but my computer just won’t recognize my gpu.

My hardware:
- PNY Geforce RTX 5070 Ti
- Gigabyte B850 Eagle Wifi6e
- AMD Ryzen 5 9600X
- MSI MAG A750GL PCIE5, Fully Modular Compact Gaming 750W Power Supply
- Manta XSky DDR5 32GB

Current State:
- Gpu light turns on but fans don’t spin
- Black screen when monitor is plugged into GPU
- Device manager does not detect GPU

- Nvidia driver installer does not detect GPU
- Computer works on integrated AMD gpu

What I’ve tried:
- Changed gpu slot from PCIEX16 to PCIEX1_1
- Turned on hidden devices in device manager and scanned for new hardware
- Tried to install nvidia drivers (but couldn’t complete because it didn’t detect the gpu
- Changed pcie from auto to gen 4 and 5 manually
- Reconnected power cord and adapter
- Updated bios
- Installed Gigabyte Control Center and installed all recommended drivers
- replaced gpu with a friend’s 5070ti to see if there was a problem with this specific card (no difference between the two cards noted

- Connected PSU directly to GPU using a 12v 6x2 connector

- Resetting my CMOS

- Trying a new PSU (it seems to still work the same as the previous PSU)

- Using Display Driver Uninstaller to clear any traces of drivers

Things I haven’t tried:

- trying a new motherboard- This feels like the next stop, and I obviously feel really reluctant to try that. I guess it’s technically possible that I somehow damaged the pcie slot in the motherboard, but my guess is that an accidental scratch wouldn't lead to the motherboard just fully not recognizing that the gpu is there? I could be wrong

Any thoughts? As i said, this is my first time, so if there’s something obvious i might have missed, please let me know! Thank you!
