Device not recognized during startup.
In the past few days my computer would freeze while playing Valorant. It shut down because VGA wasn't detected. My hardware includes a Z690 TUF ASUS D4 12700KF (no integrated GPU), an RTX 3070 at 64GB, 3600MHz DDR4 from a TFLOAT 1 NVMe SSD, and a 650W TingTong power supply. I've already tried two different GPUs—one works on another machine—and the steps I took didn't help. I'm trying to reinsert the GPU, check the RAM, use a different cable, or switch to HDMI. It's really confusing.
Check if you can start using another GPU, open the Windows Event Viewer, and look for any issues that might cause a crash. I’ve used this method to identify faulty drivers.
