I was planning to move my PC to a Lian Li A3 case, but while checking it out, I noticed a small slow-blinking red light right above my GPU. I reseated the GPU and checked the power cables, but I'm not sure what to do next. My PC has been running fine with no crashes or performance issues. Just for reference, my motherboard is a Gigabyte Aorus Elite Z690M AX DDR4.

First off, as long as your PC is functioning properly, that light might not be a big deal. Have you checked your motherboard manual? Some boards have status lights that indicate certain conditions. If nothing’s wrong with performance, it’s probably not a critical issue.
I've heard that some red lights can be BIOS false alarms, especially if you haven’t experienced any issues. It might be worth checking if any BIOS updates are available for your motherboard, as these can sometimes resolve odd behavior like that.
