"New" GPU only works with HDMI - display ports don't work

[anoor9000]

Hi all, I recently swapped out my GTX 1080 for an RTX 3060 to do some local LLM stuff.

 

I DDU'd the old driver, shut down, then swapped the GPU.

 

At first, I got NO output on my monitor even though the system was booting fine. I eventually cleared the CMOS, plugged into the HDMI port on the GPU, and it finally booted. I took that chance to install the NVIDIA drivers. Then I shut down, and plugged in the displayport cables I usually use. 

 

At that point, nothing happens. No splash screen. No display on either of my monitors on ANY of the 3 display ports. Only the HDMI port works. I've cycled the monitors, the computer, etc.

 

Any suggestions? Thanks everyone! This is a used GPU so I'm wondering if the guy sent me a dud or it's something weird with my drivers. 

 

CPU: AMD Ryzen 7 3700X 3.6 GHz 8-Core Processor  ($0.00) 
CPU Cooler: Cooler Master MasterLiquid 240 66.7 CFM Liquid CPU Cooler  ($0.00) 
Motherboard: MSI B450 GAMING PRO CARBON AC ATX AM4 Motherboard

try a different pcie slot, and contact the seller to see if they had the same issues.

Do you have UEFI mode enabled in bios?
