Device not recognized, GPU not found.
PC uses Ryzen 5 5600g, GPU is gigabyte Aorus 3070. Mobo is B550M Pro with VDHWIFF and WiFi. PSU is 750 semi-modular bronze NXT. Recently my PC froze and the monitor stopped working, saying signal not detected. I looked in Device Manager but didn’t find the GPU, even after checking hidden devices. Tried many fixes online—updated BIOS, changed settings, reset CMOS, reinserted the GPU—but nothing works. Need assistance.
Consider forcing PCIe 3.0 through the slot, but note that the 5600G doesn't support PCIe 4.0 and the AUTO option may not function correctly. This usually stops the system from starting entirely, making the fact that it boots with the 3070 connected a red flag. Generally, I'd rule out Windows by only trying to make it start from the 3070 in UEFI/BIOS. If it can't display anything there, it's unlikely to work in Windows either.
