I've got this 3070TI that only lit up at boot (no fans and not seen by PC). When taking it apart I noticed the PCIe GPU power plugs to the GPU had pin 3 from the top of the card pushed out of the connector. Once I got the pins realligned I put the card back together to try it again. Now it lights up and the fans come on but the PC does the normal single beep for boot and right away does three fast beeps and fails to boot. I unplug the card and the PC boots normally again. Clearly another issue with the card. Anyone see this before? Feel like some progress...
