You're experiencing a problem where only one PCIe slot appears after a cold boot, causing high GPU usage during gaming. Rebooting resolves the issue by detecting all slots. Possible causes could include driver conflicts, BIOS settings, or hardware configuration mismatches. Your system specs and recent updates suggest you're on the right track, but checking the BIOS compatibility and ensuring proper PCIe slot mapping might help.

Yes, you're way behind on BIOS revisions. Starting with F33, it notes #4 "Enhanced PCIe compatibility" So maybe F33 and newer fixes the issue.

You can install F36 directly, but it's often better to start with F33 first for proper setup.

You can proceed straight to F36. Regarding your GPU setup, did you apply any stress to the GPU while reviewing this? Note: Lowering the PCIe gen speed is typical to conserve power, but lanes shouldn't be affected as highlighted by @Blue4130, so that wasn't the case. It's normal for the system to reduce PCIe gen to save energy, but not for increasing lanes, as pointed out. I'm sure this will help you avoid unnecessary strain and keep your performance stable.

You can jump straight to F36. However, it's probable that any personal configurations you set in the BIOS will revert to their default values. Remember to save any custom adjustments—like fan curves—and capture them with a photo on your phone if you want to retain them.

I am not sure what your question means so I assume I didn't. The only thing I did, when I built the PC (last October), was to change the behaviour of fans as far as I remember. I'm not tech-savvy so I try not to mess around too much if I don't know what I'm doing. This raises the question: has this happening for longer than I noticed? I don't know. I have played a variety of games and I have never had any problem. I think my games would be lagging hard? I played Black Myth Wukong without major issues. Thank you for the advice. I think I did change some fan settings when I built the PC but, other than that, I didn't mess around. I just hope updating the BIOS fixes the issue.

Another problem occurred: After updating the BIOS, GPU-Z still displays an x16 PCIe slot even after a cold boot. The value changes—showing x16 1.1 during idle, then jumping to 2.0 and 4.0 while gaming. Should I be concerned? Is this typical?

It won't affect the PCIe generation, though the lanes remain unchanged.
