(PROBLEM RESOLVED) GPU Fails to Connect to PCIe Port
This observation is valid. The latch should automatically confirm if the card is properly seated. However, it seems the mechanism isn’t engaging correctly when trying to insert the card. You’re able to adjust the latch manually and trigger the button on the slot, which suggests you understand how it works.
The latch design for the top slot might be the reason. Over the past few years, PCI-E X16 slots have behaved similarly to regular slots, featuring boards from ROG Maximus/Crosshair and Gigabyte Aorus.
Observe the progress with the third board. Stay informed and let us know.
The latch is merely a plastic component and doesn't influence the electrical signals in the PCIe slot. It shouldn't be necessary; the screws and the slot should secure it firmly, preventing any movement. Ideally, it should hold in place without needing manual adjustment. Its only function is to stop powering on if it fails. If it doesn’t work, simply tilting the PC case can help keep it in position.
It seems we're confirming the approach. I'll go ahead and do it manually to lock it in, just as suggested. I was worried about possible issues with a manual latch click, especially if the PC is powered on, but good to hear it works fine. If lifting and screwing still causes problems, I'll consider a different board design instead of leaving the case flat. I won't have space like that on my desk, and I doubt airflow or pump placement would be affected. I'll update you later if everything checks out. Thanks!
In short, the third board arrived with damage, so I didn’t test it at all because the box had dents. The fourth board looked fine but the issue persisted. I tried opening it manually, inserted the card, and started it up—initially everything worked. There were a few error codes, which I resolved after some research. Now the PC is running properly and shows a picture. This was a tough fix, especially for someone new to building, but I really appreciate your help. Thanks a lot!
