Hi everyone! I'm working on upgrading my video editing workstation (spec below) and as part of that I bought a 2nd GPU; an Nvidia 3070 Ti. I bought it used so it may be a faulted GPU but the seller has sold many of the cards, and gotten nothing but positive feedback and claims the card was working before sale so I'm inclined to believe them.

Troubleshooting steps I've tried: - Swapping my 3060 for the 3070 in position and checking if it was detected in that slot.

• Checking all power supply cable seatings

• Checking the UEFI to see if the card was detected by the BIOS (It wasn't)

• Resetting the display drivers

• Deleting all display drivers and restarting

• Forcing a windows hardware rescan

• Forcing a UEFI hardware rescan

• Installing the latest version of the bios

• Checking for any chipset updates

• Checking the card seating

• Swapping the 3060 to different slots to check if there was a bad mobo slot

• checking the gpu pins for any debris or damage

I'm curious if there's anything else that I'm missing to try. I've never run dual GPUs before so I'm not super familiar with any special configurations that need to be done and google hasn't been terribly helpful.
