I'm having a weird issue where my PC only boots up with the monitor connected to the motherboard instead of the GPU. I had to lay my PC on its side to adjust some parts, and after reconnecting everything, I got a black screen on startup. When I plugged the monitor directly into the motherboard, it booted up fine. Once I switched back to the GPU, everything worked normally again. I'm just curious why this happened in the first place. Any insights would be really helpful! Happy holidays! Here are my specs: AMD Ryzen 7 7700X, 32 GB DDR5 RAM, Radeon 7900xt GPU, Gigabyte B650 Gaming X AX V2 motherboard, and I'm running Windows 11 with three monitors.

Just to clarify, were you using a new GPU? If not, it sounds like your system might have thought something had changed, maybe causing it to reset some hardware settings. Checking for BIOS updates might be a good idea since new updates often resolve such quirks.
With three monitors, diagnosing this kind of issue can be tricky. You’ve got a lot of potential factors at play. Just make sure your BIOS, GPU, and chipset drivers are all up to date. Also, verify that everything is securely plugged in. If it happens again, it could be something as simple as a driver issue or an intermittent connection.
It's possible that when you laid the PC on its side, the GPU was slightly loose in its PCIe slot. This can occasionally happen due to GPU sag. Just the act of reconnecting everything might have secured it better. It's a bit rare, but it’s definitely worth checking to make sure all connections are snug and the GPU is properly seated.
