The computer boots up but fails to detect the graphics card.
In short, I recently purchased a 3080 graphics card, functioned it for a couple of weeks without issues, then upgraded its case for better airflow. When I finally powered it on, there was no display output from the card itself. Only my CPU's built-in graphics appeared in Device Manager, indicating the card wasn't connected and needed manual reconnection. I've tried various other GPUs, different PCIe slots, but the problem persists. I'm unsure how to proceed.
