The M.2 Gen 3 x4 port stops working once you connect the GPU.
You're experiencing an issue where one of your three M.2 slots isn't working properly after installing your GPU. This could be due to a faulty connection, incorrect BIOS settings, or compatibility problems. Try checking the physical connections, ensuring the slot is properly seated, and verifying that your motherboard supports the GPU model. If the problem persists, consider updating your BIOS or consulting your hardware manufacturer for support.
Identify your motherboard model and CPU specifications. Refer to the manual for available PCIe slots.
