I just finished assembling my new PC, but I'm stuck with a POST VGA failure light on the motherboard. My monitor isn't displaying anything, and I'm not able to access the BIOS. The graphics card seems to be functioning since it's warm to the touch, so I'm hopeful that power is getting to it. I've reseated the card, and it clicked into place, but there's a little bit of movement without the screws securing it to the case, which I'm not sure is normal. I'd appreciate any tips or advice on how to troubleshoot this issue! P.S. My specs are: Intel i5 12400F, GeForce 3060 12GB, B760M Gaming Plus WiFi DDR4 motherboard, and 32GB of 3200MHz RAM.

First off, make sure all your power connectors are snug. Sometimes, the GPU might not get enough juice if the connectors aren’t seated properly. Since you're using a 6+2 PCIe connector, double-check that it's securely connected. Also, you might want to check if you're using the HDMI output from the GPU, not the motherboard—sometimes that trips people up. And it wouldn’t hurt to screw in the bracket properly; that often helps with stability and connections. Good luck!
It sounds like you've done a great job assembling everything! It's definitely important to make sure all the PCIe power connectors are fully plugged in. You should see the light on the graphics card indicating it's getting power. If you're getting that POST VGA error, it could be a seating issue—like you mentioned, if there's play when you reseat the card, it might not be making a good connection. Try to secure it in place, and if you have a different PCIe slot, give that a shot too!
