Perform a random shutdown and restart.
Your setup has been experiencing frequent black screens, shutdowns, and reboots, especially while using Fusion 360, Cura, or browsing the web. PC specs include a Gigabyte X570 Arorus Elite with a Ryzen 9 3900X, 32GB Corsair 3200MHz RAM in XMP profile, a Rocket 4 1TB M.2 NVMe SSD, and a Be Quiet Dark Rock Pro 4 with a 500W PSU. The BIOS is up to date, but issues persisted on previous models. Temperatures are normal (36°C idle, 72°C load), memory tests show no errors, and the PSU is within specs despite low wattage concerns. System logs report no errors. Possible causes could be overheating under load, driver conflicts, or power supply limitations. Consider checking cooling performance, updating drivers again, and ensuring proper ventilation.
The power source seems insufficient, especially if it's just restarting. If the CPU, RAM, etc., are unstable, you'd notice error messages. The 5700xt offers 225W TDP (unless overclocked) and the 3900x provides 105W. Likely the issue is brief power surges that overload the supply. Edit: consider lowering the GPU power limit and try slowing down the CPU and RAM. A better upgrade would be this model: https://pcpartpicker.com/product/4ZFKHx/...ga-0750-x1.

It might be several factors at play. If it completely shuts down, it’s likely a power supply issue or insufficient voltage. Running Prime95 and Furmark for two hours suggests power fluctuations could be the cause, especially during startup spikes. The RX5700XT needs a minimum 450W PSU, ideally 500W or more—your setup should meet that requirement. If it restarts, the problem could stem from software, memory, or hardware faults. Recent BIOS updates may also be involved; on my system, switching to an older version resolved the issue. Consider reverting to a previous BIOS release (like AGESA 1.2.0.3c) and checking forums for similar experiences. You might also try using F35 or F36 BIOS versions to test.
I haven't encountered any problems with AGESA 1.2.0.7, but I'm using a gigabyte board so I'm not sure. If the issue was related to software, memory, or hardware, I'd expect some unexpected behavior. He mentioned it would just shut down and restart, which suggests the power supply might be the cause. For now, I think trying to lower the CPU and RAM voltage could help. The GPU should have its power limit set to 90 or 85. If the problem is with the PSU, it should stabilize once you upgrade it.
Thank you for your feedback. I was concerned it might be a PSU problem, so I’ll lower the GPU power and monitor the situation. Appreciate the guidance! I initially suspected BIOS issues, as I moved from 34,35,36 to 37°C with persistent random black screens and reboots. The 37°C resolved the USB disconnect issue, which helped me decide to explore older BIOS versions after adjusting GPU power limits. Thanks for your support.
